 6Why Are Emergency Communication Techniques 
Different?
- Life and death communications are not part of our 
daily experience  - Most of what we say and do each day does not have 
the potential to severely impact the lives and 
property of hundreds or thousands of people  - In an emergency, any given message can have huge 
and often unintended consequences  - An unclear message, or one that is modified, 
delayed, mis-delivered, or never delivered at all 
can have disastrous results

 8Why Is Listening Efficiency Low?
Hearing what you want to hear
Juggling
Mental Tangents
Bored
Daydreaming
Dont Want to Be There
Dont Like the Speaker
Dont Understand the Topic
Forming a Response
Too Interested in Physical Characteristics 
 9Listening..The Forgotten Skill
- Listening is not the same as hearing 
 - You can have excellent hearing but still have 
weak listening skills  - Listening is a learned skill 
 - What does ineffective listening cause?
 
  10Ineffective Listening
Frustration
Misunderstandings
Embarrassment
Confused Instructions
Loss of Important Information 
 11Listening
Acknowledge the Talker
Taking In Information
Improve Communication
Invite Communication to Continue
Carry Idea Forward
Non-judgmental
Empathetic 
 12Listening Exercise from NCS Class
- An exercise to increase listening awareness.. 
 - For five minutes, list all the sounds you hear 
 - Do this 2-3 times a day in different environments 
to sharpen your listening awareness  - Perhaps even add a radio or scanner and try to 
follow the traffic as well  - Listen to weak signals on Shortwave/HF/AM 
Broadcast Band  
  13Microphone Techniques
- Using your microphone correctly can make a big 
difference in intelligibility  - Hold the mic close to your cheek, and just off to 
the side of your mouth  - Talk across, rather than into, the microphone 
 - Reduce breath noises and "popping" sounds that 
can mask your speech  - "Voice operated transmission" (VOX) is not 
recommended for emergency communication 
  14Speaking
- Normal, clear, calm voice 
 - Shouting  over-modulation and distortion 
 - Will not increase volume at the receiving end 
 - Normal pace 
 - Rushing  slurred and unintelligible speech 
 - Pronounce words carefully 
 - Making sure to enunciate each syllable and sound 
 
  15Repeater Use
- Leave a little extra time between pressing the 
push-to-talk switch and speaking  - A variety of delays can occur within a system, 
including CTCSS decode time, and transmitter rise 
time  - Leaving extra time is also necessary on any 
system of linked repeaters  - Allow time for all the links to begin transmitting
 
  16After Transmission
Pause a little longer than usual between 
transmissions any time there is a possibility 
that other stations may have emergency traffic to 
pass from time to time. A count of "one, one 
thousand" is usually sufficient. 
 17Brevity  Clarity
- Only the information necessary to get the message 
across clearly and accurately  - Extraneous information 
 - Distract the recipient 
 - Misinterpretation 
 - Confusion 
 
  18Brevity  Clarity
- If you are the message's author and can leave a 
word out without changing the meaning of a 
message, leave it out  - If the description of an item will not add to the 
understanding of the subject of the message, 
leave it out  - Avoid using contractions within your messages 
 - Words like "don't" and "isn't" are easily 
confused.  - If someone else has drafted the message, work 
with the author to make it more concise  
  19Brevity  Clarity
- Listen to a scanner 
 - Police/fire radio dispatchers 
 - Air traffic controllers 
 - Transmissions sound crisp and professional 
 - Do not editorialize, or engage in chitchat 
 - An emergency net is no place for 
 - "Hi Larry, long time no hear," 
 - "Hey, you know that rig you were telling me about 
last month...."  - Or any other non-essential conversation.
 
  20Brevity  Clarity
- Say exactly what you mean 
 - Using non-specific language can lead to 
misunderstandings and confusion  - Communicate one complete subject at a time 
 - If you are sending a list of additional food 
supplies needed, keep it separate from a message 
asking for more sand bags.  - Chances are that the two requests will have to be 
forwarded to different locations, and if combined 
one request will be lost  
  21Plain Language
- Plain Language Common terms and definitions 
that can be understood by individuals from all 
responder disciplines. The intent of plain 
language is to ensure the clear and accurate 
communication of information during an 
incident.  - FY07 NIMS Compliance Metrics  Terms of Reference 
 
  22Plain Language
- Not everyone involved in an emergency 
communication situation will understand amateur 
slang and technical jargon  - Exception 
 - Standard "pro-words" (often called "pro-signs") 
used in Amateur traffic nets, such as "clear," 
"say again all after" and so on  
All messages and communications during an 
emergency should be in plain language  
 23Common Terminology
- Is an ICS wide fundamental 
 -  
 - Necessary for operations, planning, and standard 
operating procedures (SOPs)  - A common dialect for describing the who, when, 
why, where, what, and how of operations  
  24Plain Language
- Not all Plain Language has the same meaning 
 - For example 
 - The California Highway Patrol requests Backup 
when they need another officer in an emergency. 
They request Assistance when they want a cover 
unit.  - The Los Angeles County Sheriff uses the same two 
words, but uses them in the exact opposite 
meaning.  -  
 
  25Be Careful
- Avoid words or phrases that carry strong 
emotions.  - Most emergency situations are emotionally charged 
already, and you do not need to add to the 
problem.  - "horrific damage and people torn to bits" 
 - "significant physical damage and serious personal 
injuries"  
  26Phonetics
- Certain words in a message may not be immediately 
understood  - The best way to be sure it is understood 
correctly is to spell it but  - Spell the word using letters, it might still be 
misunderstood  - Use phonetics anytime a word has an unusual or 
difficult spelling, or may be easily 
misunderstood  
  27Phonetics
- Standard practice is to first say the word, say 
"I spell," then spell the word phonetically  - Lets the receiving station know you are about to 
spell the word he just heard  - Phonetic alphabets 
 - Most hams and some public safety agencies use the 
ITU Phonetic Alphabet  - Others use military alphabets or the APCO 
alphabet  - Make up your own phonetics has no place in 
emergency communication  
  28ITU Phonetic Alphabet

- Procedural terms with specific meanings 
 - Save time 
 - Everyone understands precisely what is being said 
  - Some pro-words are used in general communication, 
others while sending and receiving formal 
messages  
  32Pro-words

 33Tactical Call Signs
- The tactical call sign allows you to contact a 
station without knowing the FCC call sign of the 
operator  - Identify the station's location or its purpose 
during an event, regardless of who is operating 
the station  - Have a meaning that matches the way in which the 
served agency identifies the location or function 
  - Should be used for all emergency nets and public 
service events if there are more than just a few 
participants  - Net Control Station (NCS) may assign the tactical 
call sign as each location is "opened"  
  34Tactical Call Signs
- Emergency communications use tactical call signs 
exclusively to call other stations  - You dont contact another station on an emergency 
net by using their amateur call sign  - If you have a reason to call them on the net, 
they have either a DESIGNATOR (if a mobile 
station) or a LOCATION (if a fixed station) and a 
FUNCTION! 
  35Example Tactical Call Signs 
 36Example Tactical Call Signs
- Road Rally Operations on-site at 
 - MOUNTAIN TOP. This is the TACTICAL call sign 
for the over event Net Control Station.  - SERVICE TACTICAL call sign for vehicle 
maintenance area during rallies.  - CHAIRMAN TACTICAL call sign for event leader 
from the rally organization.  - START TACTICAL call sign for the initial start 
point for a specific stage in a rally.  - MID-POINT TACTICAL call sign for the midway 
point for a specific rally stage.  - SPECTATOR TACTICAL call sign for a specific 
spectator point during a rally stage.  - FINISH TACTICAL call sign for the end or 
finish point for a specific rally stage.  - SAFETY TACTICAL call sign for designated Rally 
Safety Official/Coordinator.  - ADVANCE TACTICAL call sign for Advance 
vehicle on a specific rally stage.  - PACE TACTICAL call sign for any pace 
vehicle(s) used on a specific rally stage.  - SWEEP TACTICAL call sign for sweep vehicle(s) 
used on a specific stage.  - TIMERS TACTICAL cal sign for stage timers on 
a specific rally stage.  - Other locations and tactical call signs may be 
used at specific rally events that will be 
established by the event chairman or their 
designated representative.  
  37Calling with Tactical Call Signs 
 38Calling with Tactical Call Signs 
 39Calling with Tactical Call Signs
- Calling a station 
 - Team 2, this is SAR Base 
 - RTC Command, this is SAG 21 
 - The correct response is to identify with YOUR 
call sign, followed by the prowords go ahead  - Team 2, go ahead 
 - SAG 21, go ahead 
 - To end a contact, use the term out - not 
clear  - Heres how it sounds 
 - SAR Base out, WB7OML 
 - RTC Command out, WB7OML 
 - Operations out, WB7OML 
 - What if you need to call a specific person at a 
location?  - Redmond EOC, this is RTC Command with contact 
for Deputy Smith  - What if you have a written message to deliver? 
 - Redmond EOC, this is RTC Command with traffic 
 - (Contrary to what some teach, you dont identify 
the recipient of a written message in the call - 
it will be in the message itself, and theres no 
reason to duplicate the information!) 
  40Calling with Tactical Call Signs
- Your call sign is WB7OML and you have status of 
Medic 1 to which you are assigned  - Net Control from Medic 1 with status 
 - Your call sign is WB7OML you are assigned to Rest 
2 and you need to talk directly with KE7DXW 
assigned to Rest 3 on the same net  - Net Control from Rest 2 with traffic for Rest 3 
 - Your call sign is WB7OML, spotter id KING145 and 
you have weather traffic  - Net Control from KING145 with weather 
 - Field unit assigned to SAG1 has traffic for net 
control  - Net Control from SAG1 with traffic
 
  41Calling with Tactical Call Signs
- Field unit assigned to SAG2 has a message for 
Medic1 and requests permission to pass the 
traffic.  - SAG2 Net Control from SAG2 with traffic for 
Medic1.  - NCS Medic1, can you copy SAG2? 
 - Medic1 Affirmative 
 - NCS SAG2, you may go direct with Medic1 
 - SAG2 Medic1 from SAG2 
 - (If Medic1 responds, message is passed and SAG2 
clears. If Medic1 cannot copy, SAG2 may ask Net 
Control to relay traffic.) 
  42What about FCC Call Signs?
- FCC requires that you identify at ten-minute 
intervals during a conversation and at the end of 
your last transmission  - Give your FCC call sign as you complete each 
exchange  - Tells the NCS that you consider the exchange 
complete (and saves time and extra words)  - Fulfills all FCC identification requirements
 
  43Completing a Call 
 44A Review of Habits to Avoid
- Thinking aloud on the air "Ahhh, let me see. 
Hmm. Well, you know, if..."  - PTT is not Push to Think 
 - On-air arguments or criticism 
 - Rambling commentaries 
 - Shouting into your microphone 
 - "Cute" phonetics 
 - Identifying every time you key or un-key the mic 
 - Using "10" codes, Q-signals on phone, or anything 
other than "plain language"  - Speaking without planning your message in advance 
  - Talking just to pass the time
 
  45Exercise  Tactical Call Signs
- Break off into groups of 6 
 - Assign a NCS from your group 
 - NCS assigns a tactical call sign to each student 
in their group  - Practice a roll call to get a SITREP from each 
station using tactical call signs and FCC call 
signs  - SITREP for all stations is no damage at this 
location  this is an exercise 
  46Practice
- Do you practice with tactical call signs on your 
training nets?  - Example  do a roll call and assign tactical call 
to each station responding. Use tactical call for 
remainder of the net. 
  47Lesson 6 Activities
- Using what you have learned, edit the following 
exchange to make it clear and concise.  - "KA1XYZ at Ramapo Base, this is Bob, K2ABC at 
Weston EOC calling."  - "K2ABC, this is KA1XYZ. Hi, Bob. This is Ramapo 
Base, Harry at the mic. Go ahead. K2ABC from 
KA1XYZ."  - "KA1XYZ, this is K2ABC returning. Hi, Harry. I 
have a message for you. By the way, remember to 
call me later about the get-together the club is 
having next month. Are you ready to copy the 
message?" KA1XYZ, this is K2ABC, over to you 
Harry." 
  48Lesson 6 Activities
- Based upon what you have read in this lesson, 
list five errors to avoid when communicating 
during an emergency.  
  49Lesson 6 Questions
- In emergency communication, which one of the 
following is NOT true?  - Listening is only about 10 of communication. 
 - Any message can have huge and unintended 
consequences.  - A message that is never delivered can yield 
disastrous results.  - Listening also means avoiding unnecessary 
communications. 
  50Lesson 6 Questions

heard at the receiving end.  - Whenever possible, use voice operated 
transmission (VOX).  
  51Lesson 6 Questions
- In emergency communications, which of the 
following is true?  - Never use "10 codes" on Amateur Radio. 
 - Use "Q signals" on served-agency radio systems. 
 - Under NO circumstances use "Q" signals on a CW 
net.  - Use technical jargon when you feel that it is 
appropriate.  
  52Lesson 6 Questions
- Which of the following is always true of a 
tactical net?  - Personal call signs are never used. 
 - Personal call signs are always preferred over 
tactical call signs (such as "Aid 3").  - Personal call signs are required at ten-minute 
intervals during a conversation or at the end of 
your last transmission.  - Personal call signs are required at ten-minute 
intervals during a conversation and at the end of 
your last transmission. 
  53Lesson 6 Questions
- Which of the following is the most efficient way 
to end an exchange on a tactical net?  - Say "Over".

  55Lesson 7 - Introduction to Emergency Nets 
 56Definitions
- Net A group of stations who gather on one 
frequency, with a common purpose. The net 
provides a structure and organization to allow an 
orderly flow of messages.  - Net Control Station (NCS) The station in charge 
of the net and directing the flow of messages and 
general communications.  - Formal Messages Written messages that are sent 
in a standardized format.  - Informal or Tactical Messages Brief verbal or 
informal written messages, intended for direct 
and immediate delivery.  - Traffic A term referring to messages sent over 
Amateur Radio, usually formal, written messages. 
More generally, any messages or activity on a 
particular frequency.  
  57Definitions
- Pass to send messages from one station to 
another.  - Third Party Traffic Messages transmitted on 
behalf of a person or organization other than a 
licensed Amateur Radio operator. This term also 
applies to when a person other than a licensed 
operator is allowed to use the microphone.  - Liaison Station A station responsible for 
passing messages between different nets.  
  58What is a Net?
- Network 
 - Something resembling an openwork fabric or 
structure in form or concept, especially  - A complex, interconnected group or system 
 - An extended group of people with similar 
interests or concerns who interact and remain in 
informal contact for mutual assistance or support  - A net of amateur radio service operators is one 
of the most effective methods of providing 
primary or supplementary communications support 
for a variety of public service or emergency 
activities or events  - A Declared Net is a net started with a statement 
of purpose 
  59What is an Emergency Net?
- An "emergency" net is a group of stations who 
provide communication to one or more served 
agencies, or to the general public, in a 
communications emergency.  - An emergency net may be formal or informal, 
depending on the number of participants and 
volume of messages.  
  60Net Formats
- Directed (formal) Nets 
 - Net control station" (NCS) organizes and 
controls all activity  - One station wishing to call or send a message to 
another in the net must first receive permission 
from the NCS  - Directed nets are the best format when there are 
a large number of member stations  
- Open (informal) Nets 
 - NCS is optional 
 - When a NCS is used at all, he usually exerts 
minimal control over the net  - Stations may call each other directly 
 - Open nets are most often used when there are only 
a few stations and little traffic  
  61Net Formats
- Directed Net 
 - NCS declares the net active 
 - NCS controls the frequency 
 - Normal use of the frequency stops 
 - Specific net topic, conditions, and/or 
instructions for check-in is given 
- Open Net 
 - Net is declared, not much happening 
 - Generally normal repeater use 
 - NCS may be there but not in tight control of the 
frequency  
  62Net Formats
- Informal nets 
 - Interest Group Nets 
 - Swap Nets 
 - Training Nets 
 
- Formal Nets 
 - Traffic Nets 
 - Emergency Nets 
 - Started after a request for service has been 
submitted by a served agency through an 
appointed, local amateur radio Emergency 
Coordinator 
  63ICS Command Net
- Usually only one Command Net is used during an 
incident by the command and general staff  - The positions down to Division/Group Supervisors 
will likely need 2 radios, one on the Command 
Channel and one for Tactical use.  - Scanning may be a solution, but it is highly 
recommended to avoid it if possible.  - It may be patched via a gateway when personnel 
are on disparate radio systems  - Cache radios or radios can be programmed for 
command and general staff use  - This frequency/talkgroup is also used as a link 
between the incident and the Dispatch Center  
  64ICS Tactical Nets
- There may be several Tactical Nets at the 
Division (geographic)/Group (function) Level  - May use mobile communications units at the 
incident to patch Tactical Nets  - Other Nets include 
 - Ground-to-air 
 - Staging 
 - Logistics Net 
 
  65Available/Assigned Nets
- Available Nets (ICS Form 217A) 
 - Shared Channels Reference 
 - TIC Plan 
 - Frequency/Talkgroup agency listing 
 - Local/Region Communications Plan 
 - Assigning Nets 
 - Coordinate with the Local COMC 
(Communications Coordinator)  
  66ICS Form 217ACommunications Resource 
Availability Worksheet 
 67Types of Emergency Nets
- Traffic net 
 - Handles formal written messages in a specified 
(i.e. ARRL) format.  - National Traffic System (NTS) 
 - ARES or RACES traffic nets may be directed or 
open depending on their size  
- Tactical nets 
 - Real-time coordination of activities related to 
the emergency  - Messages are usually brief, and frequently 
unwritten.  - Usually has a NCS, but may be directed or open 
 - The NCS may have other duties or responsibilities 
as well  
  68Types of Emergency Nets
- Resource" or Logistics" net 
 - Acquire resources and volunteers and handle 
assignments  - Usually a directed net 
 - Accept check-ins from arriving volunteers, then 
directed to contact an appropriate station or to 
proceed to a specific location.  - Locate needed resources, such as equipment, food, 
water and other supplies for emcomm volunteers  
- Information net 
 - Open net used to collect or share information on 
a developing situation  - Official bulletins from the served agency 
 - May be sent by the NCS 
 - An agency liaison station 
 - Official Bulletin Station (OBS) 
 - Example is a SKYWARN weather net activated during 
a severe storm watch  
  69Checking Into an Emergency Net
- You will need to "check in" to a net 
 - When you first join the net. 
 - When you have messages, questions, or information 
to send.  - Directed net 
 - Listen for the NCS to ask for "check-ins" 
 - Listen to any specific instructions 
 - "check-ins with emergency traffic only" 
 
  70Checking Into an Emergency Net
- At the appropriate time, give only your call 
sign.  - If you have a message to pass, you can add, "with 
traffic."  - If it is an emergency message, say "with 
emergency traffic."  - The same is true for stations with priority 
traffic.  - Wait for a response before offering more 
information.  - Checking into a directed net when the NCS has not 
asked for check-ins is usually considered a bad 
practice.  - If a long period passes with no request, you 
might wait for a pause in the net activity and 
briefly call the NCS like this  -  "Net control, WB7OML, with traffic."
 
  71Checking Into an Emergency Net
- Open net 
 - Call the net control station with your call sign 
 - If you have a message to pass, you can add, "with 
traffic."  - If it is an emergency message, say "with 
emergency traffic."  - If there appears to be no NCS, call anyone on the 
net to find out if anyone is "in charge" and make 
contact with them.  - If you are already part of the net and have a 
message to send, simply wait for the frequency to 
be clear before calling another station  
  72Checking Into an Emergency Net
- If you are not part of the organization operating 
the net, do not just check in and offer to 
assist.  - Listen for a while 
 - Be sure you have something specific to offer 
before checking in  - Ability to deliver a message close to your 
location when none of the regular net members can 
  - If they really do seem to need help that you feel 
you can provide, you might check in briefly to 
ask if they have a "resource" net in operation, 
then switch to that frequency  - If not, make a brief offer of assistance to the 
NCS  
  73Checking Into an Emergency Net
- If you are not part of the organization operating 
the net  - Do not be too surprised if you receive a cool 
reception to your offer of help  - Emcomm managers prefer to deal with people with 
known training and capabilities, and with whom 
they have worked before  - May assign you as an apprentice, logger, or as a 
"runner".  - If you are given such an opportunity, take it!
 
  74Passing Messages
- WB7OML with traffic 
 - WB7OML list your traffic 
 - Destination and priority 
 - NCS will direct you to pass each message to the 
appropriate station in the net, either on the net 
frequency, or another frequency to avoid tieing 
up the net  - Sign with your tactical call sign and your FCC 
call 
  75Passing Messages
- NCS "WB7OML, list your traffic. 
 - You "WB7OML, two priority for Seattle EOC, one 
welfare for the Section net.  - NCS "Seattle EOC, call WB7OML for your traffic. 
 - Seattle EOC "WB7OML, Seattle EOC, go ahead. 
 - You "Number 25, Priority... 
 - (After you have sent your messages to the Seattle 
EOC, the NCS will next direct the section net 
liaison station to call you for their message.)  
  76"Breaking" the Net
- Net is in progress 
 - You have emergency traffic to send 
 - Break" into the net 
 - Wait for a pause between transmissions and simply 
say  - "Break, WB7OML" 
 -  NCS will say, "Go ahead WB7OML" 
 - You respond, "WB7OML with emergency traffic"
 
  77Checking Out of an Emergency Net
- Always let the NCS know when you are leaving the 
net, even if it is only for a few minutes  - Reasons for checking out of (leaving) a net 
 - The location of your station is closing 
 - You need a break and there is no relief operator 
 - You have turned the location over to another 
operator  - Remember to sign with your FCC call sign
 
  78Special Situations for Checking Out
- If you are asked by someone in authority, such as 
a law enforcement officer, to move your station, 
then move immediately and without argument. 
Notify the NCS of the situation at the first 
appropriate opportunity.  - If you are requested by someone in authority to 
turn off your radio, or to refrain from 
transmitting, do so immediately and without 
question. Do not notify Net Control until you 
have permission to transmit again, and can do so 
safely. There is usually a good reason for such a 
request. It may be an issue of security, or it 
may be a potential hazard, such as an explosive 
devise that could be triggered by RF energy. 
  79Levels of Nets
- Network systems are often "layered" for greater 
operating efficiency  - Local messages travel between destinations 
directly on local nets  - When a message has to go to a distant city, it is 
passed to a regional net, and if it is really 
distant, to a long distance net  - National Traffic System (NTS)
 
  80Levels of Nets 
 81National Traffic System 
- Created by the ARRL and authored by George Hart, 
W1NJM in 1949  - Handle medium and long distance traffic 
 - In an emergency, the National Traffic System can 
be used to provide a link from the area impacted 
by the emergency to the outside world  - Hierarchical (layered) set of nets 
 - Local nets 
 - Section Nets 
 - Region Nets 
 - Area Nets 
 - Transcontinental Corps 
 
  82Non-Voice Nets
- Emergency nets may also use other modes of 
communication besides voice  - Traffic nets have used CW since the beginning of 
Amateur Radio  - High speed CW nets can actually handle more 
messages per hour than most voice nets  - Packet communication on VHF and UHF 
 - Accuracy and a record of the message 
 - HF digital modes on long distance circuits 
 - AMTOR and PACTOR 
 - PSK31
 
  83WinLink 2000 
- Blends radio and Internet transmission paths to 
permit rapid and seamless email message transfer 
to stations anywhere on Earth  
  84FNpsk  FNpack 
- FNpsk is a windows program designed to allow easy 
handling of ARRL format messages via PSK31  - FNpack program provides for message handling and 
net management of amateur radio emergency 
communications applications via packet networks  
  85Lesson 7 Student Activities

  86Lesson 7 Questions
- Which of the following best describes a net? 
 - A group of stations who purposely frequent the 
airwaves.  - A group of stations who gather on one frequency 
with a purpose.  - A group of stations who occasionally meet on 
various frequencies.  - A group of stations who propose to meet at a 
particular time. 
  87Lesson 7 Questions
- What is a major difference between an "open net" 
and a "directed net"?  - The presence or absence of full control by a Net 
Control Station.  - The presence or absence of formal traffic. 
 - The type of radio traffic on the net. 
 - The approval or sanction of net operations by the 
FCC. 
  88Lesson 7 Questions
- Which of the following is true of a "tactical 
net"?  - The net is used to acquire volunteers and to 
handle assignments.  - The net is used for the coordination of 
activities associated with future emergencies.  - The net may be directed or open, but will usually 
have a Net Control Station.  - The net handles only formal traffic.
 
  89Lesson 7 Questions
- When should you check in to an emergency net? 
 - When you want to comment on something that 
someone else has said.  - When you are tired of listening. 
 - When you first join the net and when you have 
messages, questions or relevant information.  - When you first join the net and when you would 
like to send greetings to one of the 
participating stations. 
  90Lesson 7 Questions
- What is the most frequent cause of errors on 
voice nets?  - Speaking too softly. 
 - Speaking too rapidly. 
 - Failure to write down the message before sending 
it.  - Failure to copy the message exactly as it was 
received.

 93Lessons 8  Basic Message Handling I Lesson 9  
Basic Message Handling II 
 94The Big Question
- In Emcomm or Public Service Communications, are 
most messages Formal or Informal or Tactical ? 
  95Types of Traffic
- Formal message traffic 
 - Fault-intolerant information (for example, lists 
of names of authorized personnel)  - Requires authentication or signoff of originator 
or recipient  - Passes through several 'hands' between originator 
and destination  - Requires a formal paper trail to verify receipt 
and reply  - Informal message traffic 
 - Does not require formal authentication of the 
originator or recipient  - Logged by sending and receiving stations but does 
not require the use of message forms or 
structured handling procedures  - Tactical message traffic 
 - Goes directly from originator to recipient 
through only two radio operators (sender and 
receiver)  - Does not require a paper trail or record of 
communication  - Does not require formal authentication of 
originator or recipient  - Must be delivered in a timely or instantaneous 
manner.  
  96Formal Traffic
- Pros 
 - Equivalent to a telegram or email 
 - Written in a specific format, i.e. ARRL 
 - Two or more people will handle them before 
reaching the recipient  - Stations working formal message traffic operate 
like a telegram office or service desk, accepting 
messages in written form from a number of clients 
and transmitting them via voice, packet or other 
modes either directly to a destination or through 
a formal traffic network (like the NTS network)  - Formal message handling guarantees high accuracy 
and validation of receipt, and is very good in 
situations where direct sender-to-receiver 
communications is unavailable 
- Cons 
 - Formal message handling tends to be slower than 
informal and tactical messaging  - Most clients will find the formalized procedures 
of authentication and submission very 
intimidating and user-unfriendly, making the use 
of amateur resources unattractive even in times 
of need.  
  97Informal Traffic
- Familiar to operators who have worked on public 
service events or participated in routine radio 
nets  - Most common type of messaging used in emergency 
situations  - Verbal or written but not in a specific format 
 - Best used for 
 - Non-critical and simple messages 
 - Messages that require immediate action 
 - Those are delivered directly from the author to 
the recipient  - Does not require extensive operator experience, 
intimidating authentication and submission 
procedures for clients, or much overhead  
- Typically, operators will be imbedded in an EOC 
or at the 'office' of a facility and will work 
alongside emergency management personnel to 
provide whatever communications are required  
  98Tactical Message Traffic
- Equivalent of a telephone conversation or 
tactical radio communication (such as fire and 
police tactical communications)  - Tactical messaging is used between stations that 
are attached to single client or persons (such as 
an aid coordinator)  - Tactical communications involves an operator 
repeating a client's information or instructions 
over the radio channel, or in some cases allowing 
the client to speak directly over the radio  - The originator and recipient may actually present 
during the QSO, allowing for rapid 'back and 
forth' communications that may be essential in 
some situations  
- Example 
 - A radio operator who is shadowing a critical 
resource person during an emergency is likely to 
use tactical or informal messaging, rather than 
formal messaging  
  99Informal Messages 
- Informal or tactical messages are not written out 
in ARRL format, or not written at all  - This does not mean that accuracy is any less 
important  - If someone gives you a short message to relay to 
someone else, you should repeat it as closely to 
the original as possible  - Messages that will be relayed more than once 
should always be sent in ARRL format to prevent 
multiple modifications  
  100Informal Verbal Messages
- Some emergency messages are best sent informally 
in the interest of saving precious seconds  - If you need an ambulance for a severely bleeding 
victim, you do not have time to compose and send 
a formal message.  - The resulting delay could cause the patient's 
death 
  101Formal vs. Informal
- Formal messages are not needed for most 
 - Real-Time Tactical Communications 
 - Direct conversations between third parties 
 - Life-safety matters when timing is critical 
 - Most routine task assignments 
 - Most routine task completions 
 - Most routine resource coordination 
 - Record routine exchanges as line-items in your 
Communication Log (such as ICS 309) 
  102Formal vs. Tactical Traffic
- Sending formal traffic takes time 
 - Sound Shake example ? NCS tried to send 
everything as formal traffic, and only a small 
fraction of the messages were sent, most late  - Not all messages need to be sent as formal 
traffic!!  - NTS was designed to deliver messages across the 
country in 24 hours  - E.g. Disaster Welfare Inquires (DWI's) from the 
American Red Cross  - Many emcomm messages need delivery in minutes
 
  103Message Authoring -- Them Or Us? 
- One of the oldest arguments in emcomm is the 
question of whether or not emcomm personnel 
should author (create) agency-related official 
messages  - If your job is strictly communication, and the 
message is not about the communication function 
you are providing, the best answer is "no"  - No direct authority and usually lack necessary 
knowledge  
  104Message Authoring -- Them Or Us?
- You should always work with a message's author to 
create text that is short, to the point, and uses 
the minimum number of words necessary  - If the author tells you to "just take care of the 
wording for me," it is still a good idea to get 
their final approval and signature before sending 
the message  
  105Message Security  Privacy 
- Information transmitted over Amateur Radio can 
never be totally secure  - FCC rules strictly prohibit us from using any 
code designed to obscure a message's actual 
meaning  - Messages sent via Amateur Radio should be treated 
as privileged information, and revealed only to 
those directly involved with sending, handling, 
or receiving the message  
  106Message Security  Privacy
- In general, any message with personally 
identifiable information about clients of the 
served agency should be avoided -- this is a good 
policy to follow with any agency if you are in 
doubt  - Messages relating to the death of any specific 
person should never be sent via Amateur Radio  - Sensitive messages should be sent using 
telephone, landline fax, courier, or a secure 
served-agency radio or data circuit.  
  107Message Security  Privacy
- There are ways to reduce the likelihood of casual 
listeners picking up your transmissions  - Use a digital mode packet, PSK31, fax, RTTY, 
AMTOR, digital phone, etc.  - Pick an uncommon frequency -- stay off regular 
packet nodes or simplex channels.  - Do not discuss frequencies or modes to be used 
openly on voice channels.  - Avoid publishing certain ARES or RACES net 
frequencies on web sites or in any public 
document.  
  108Privacy
- EmComm personnel must NOT discuss disaster 
information when media is nearby  - Names are not used in messages except to identify 
the agency contacts  - Refer media requests to the agencys Public 
Information Officer  - HIPAA
 
  109HIPAA
- Health Insurance Portability  Accountability Act 
of 1996  - Privacy  Security  Confidentiality 
 - PHI ?Protected Health Information 
 - Relates to the past, present, or future health of 
the individual, payments, and identifies or can 
be used to identify the individual  - de-identified data does not fall under HIPPA 
rules  - PHI can be 
 - Paper copies 
 - Patient Files 
 - Telephone calls, email, voicemail 
 - Verbal communications 
 - FAX transmissions 
 - Internet/intranet transmissions 
 - Cameras/voice recorders on cell phones/PDAs 
 - Radio Communications 
 
  110PHI
-  Health Plan Numbers 
 - License Numbers 
 - Vehicle Identification Numbers 
 - Account Numbers 
 - Biometric Identifiers 
 - Full Face Photos 
 - Any Other Unique Identifying Number, 
Characteristic or Code  
- Names 
 - Addresses including Zip Codes 
 - All Dates 
 - Telephone  Fax Numbers 
 - E-mail Addresses 
 - Social Security Numbers 
 - Medical Record Numbers 
 
  111Incidental Disclosure
- Incidental Disclosure generally refers to a 
sharing of PHI that occurs related to an 
allowable disclosure of PHI  - An incidental disclosure is allowed if steps 
are taken to limit them ? try to prevent them  -  
 - For example, visitors may hear a patients name 
as its called out in a waiting room or overhear 
a clinical discussion as they are walking down a 
hallway on the unit 
  112How Does HIPAA Impact You?
- Role-based Access 
 - Overheard conversations 
 - Overseen patient treatment 
 - Overseen medical records 
 - Inappropriate requests to transmit PHI over the 
radio  - If your agency insists, have an official sign the 
log book indicating they demanded it! 
Failure to Comply Can Result in Civil  Federal 
Criminal Penalties 
 113Message Handling Rules
- Do not speculate on anything relating to an 
emergency!  - Pass formal messages exactly as written or spoken 
 - Apparently misspelled words or confusing text 
must be sent exactly as received  - Only the original author may make changes 
 
Should you return a message to the author before 
first sending it if it seems incorrect or 
confusing? 
 114Message Handling Rules
- Non-Standard Format Messages 
 - Passed exactly as received 
 - It is critical that you include the signature and 
title of the sender in every message  
  115Message Handling Rules
- ACCEPT ONLY MESSAGES YOU CAN RELAY OR DELIVER 
 - Try to accept only those messages you can forward 
or deliver in a timely fashion  - Sometimes you may be asked to do otherwise as a 
liaison station or for store and forward  - If you accept a message, and are unable to pass 
it on promptly, try to find another station to 
accept it and keep it moving  - Phone a fellow amateur to take custody if you can 
not handle it properly  - Mailing, personal delivery, telephoning neighbors 
of the addressee, etc., are alternative methods 
to direct telephone delivery  - Ask fellow amateurs for help if you have 
difficulties. 
  116Message Handling Rules
- ACCEPT ONLY MESSAGES WHICH MEET FCC RULES 
 - Accept only messages in which content and purpose 
comply with the FCC regulations in force 
regarding third party traffic,  - Prohibition of "business" traffic 
 - Encryption 
 - Other rules regarding prohibited communications
 
  117  118Formal Written Message Formats 
 119Disaster Welfare Message 
 120ARRL Radiogram Form
- Preamble Message number, precedence, HX 
(optional handling code), station of origin, 
check (text word count), place of origin, time 
filed (optional), and date.  - Addressee Name, call sign (if a ham), full 
street address, city, 2-letter state 
abbreviation, zip code (very important)  
telephone (be sure to include area code).  - This Radio Message was received atStation 
identification and location.  - Text 25 words maximum, 5 per line Use the word 
xray for a period (.) and query for a 
question mark (?). Last word is salutation 
(i.e., 73, Love, etc.)  - Signature (Write-in above RECD block) Name  
call sign of person who wrote the message  
include full phone number if not a Ham or if new 
to NTS. 
- RECD  SENT Record the names and call sign of 
the person you recd the message from and/or 
sent/forwarded the message to, along with the 
date  time (PST/PDT or Z). 
  121Components of a Standard ARRL Radiogram
- Preamble 
 - Message number 
 - Originating station 
 - Message precedence 
 - Origination date  time 
 - Address 
 - Recipient name 
 - Street address or PO box 
 - City, state, and zip code
 
- Text 
 - Limited to 25 words or less when possible (new 
form  50 words)  - Written in lines of five words (ten for keyboard) 
 - Punctuation should be used only when the meaning 
of the message would not be clear without them  - Signature 
 - Single name 
 - Name and call sign 
 - Full name and a title 
 - Occasionally a return address and phone number
 
  122Block 1 - Message Number
- No standard way of numbering messages 
 - Number assigned by the station that first puts 
the message into ARRL format  - Common practice is to use a numeric sequence 
starting with the number "1" at the beginning of 
the emergency operation  - Consecutive (1, 2, 3..., starting over at the new 
year or monthly)  - Order by month  number (507  7th you originated 
in May 11244  244th message you originated in 
November  - One common problem is keeping track of messages 
from multiple field station locations  - Each field location assigns a number starting 
with 1  - Preface the message number with the tactical call 
sign or abbreviation of the field site  - Example Group Health Central initiates their 
first message  - Message number is GHC1 read as GOLF HOTEL 
CHARLIE 1  
  123Block 2 - Precedence
- The Precedence of the Message determines what 
order the messages will be handled  - Four precedence are used in ascending order of 
priority  - Routine R 
 - All traffic that does not meet the requirements 
for a higher precedence  - Not used during emergencies 
 - 99.99 of all messages have this precedence. 
These messages will be handled last.  - Welfare W 
 - Inquiry as to the health and welfare of an 
individual in a disaster area  - Message from a disaster victim to friends or 
family  - Handled before ROUTINE traffic 
 - Priority P 
 - Important messages with a time limit 
 - Any official or emergency-related messages not 
covered by the EMERGENCY precedence  - A notification of death or injury in a disaster 
area  - Usually only associated with official traffic to, 
from, or related to a disaster area  - EMERGENCY 
 - Life or death urgency ? handle first and 
immediately  - Due to the lack of privacy on radio, EMERGENCY 
messages should only be sent via Amateur Radio 
when regular communication facilities are 
unavailable 
  124Block 3 - Handling Instructions
- HXD -- Report to originating station the identity 
of the station who delivered the message, plus 
date, time and method of delivery. Also, each 
station to report identity of station to which 
relayed, plus date and time.  - HXE -- Delivering station to get and send reply 
from addressee.  - HXF -- (Followed by date in numbers.) Hold 
delivery until (specify date).  - HXG -- Delivery by mail or telephone - toll call 
not required. If toll or other expense involved, 
cancel message, and send service message to 
originating station. 
- HXA -- (Followed by number.) "Collect" telephone 
delivery authorized by addressee within (X) 
miles. If no number is sent, authorization is 
unlimited.  - HXB -- (Followed by number.) Cancel message if 
not delivered within (X) hours of filing time 
service (notify) originating station.  - HXC -- Report date and "time of delivery" (TOD) 
to originating station.  
  125Block 4 - Station of Origin
- FCC call sign of the first station that put the 
message into NTS format  - Not the message's original author 
 - You are the radio operator for a Red Cross 
shelter. The fire station down the street sends a 
runner with a message to be passed and you format 
and send the message.  - You are the "Station of Origin," and fire station 
is the "Place of Origin" 
  126Block 5 - The Check
- Number of words in the text section only 
 - Preamble, address and signature are not included 
 - Count the words in the message and compare the 
word count to the "check" number in the preamble  - If the two numbers do not agree, the message 
should be re-read by the sending station to 
verify that all words were copied correctly 
  127Counting Words
- The first operator to transmit the radiogram 
enters the check in the preamble this check 
should carry through to destination  - The relaying operator has no authority to change 
the check unless it is determined that the check 
is incorrect  - If an error is found, the original check should 
remain in the preamble  - Example an original check of 10 corrected to 9 
would be sent "10/9  - Numbers count as one, regardless of length 
 - Punctuation is counted in the check 
 - Hyphenated word counts as 1 (e.g. out-going)
 
  128How Many Words?
- New York City 
 - 527B 
 - NYC 
 - Fifty six 
 - H O Townsend 
 - W1YL/4 
 - Thanks Xray 
 - 800MHz 
 - 146.90 MHz 
 
  129Example Word Counts
- New York City 3 words 
 - 527B 1 word 
 - NYC 1 word 
 - Fifty six 2 words 
 - H O Townsend 3 words 
 - W1YL/4 1 word 
 - Thanks Xray 2 words 
 - 800MHz 1 word 
 - 146.90 MHz 2 words 
 
  130Special Case
- Telephone Numbers 
 - ARRL-recommended procedure for counting the 
telephone number in the text is to separate the 
number into groups, with the area code counting 
as one word, the three-digit exchange one word, 
and the last four digits one word.  - 860 594 0301counts as three words 
 - 594 0301 as two words 
 - Separating the phone number into groups minimizes 
garbling. 
  131Block 6 - Place of Origin
- Name of the community, building, or agency where 
the originator of the message is located  
  132Block 7 - Time Filed
- Optional field, unless handling instruction 
"Bravo" (HXB) is used  - Unless the message is time sensitive, this field 
may be left blank for routine messages  - Completing the time field is generally 
recommended for Welfare
