WHAT IS D-STAR

• Digital Smart Technology for Amateur Radio
• ICOMs implementation of JARL open standard for
  UHF/VHF digital voice and data communications
• 2 Meter, 440 MHz and 1.2 GHz
• Consists of radios, repeaters, and (optional)
  Gateway hardware and software
• Gaussian Minimum Shift Keying (GMSK) with forward
  error correction
• New Modulation Scheme
• RF aspects remain unchanged (RF is RF)

WHY D-STAR

• Why Not D-STAR?
• Something in it for everyone
• Gateway and PC
• for Data Commx , Programmer , and Networking
  Interests
• RF for the Antenna and RF System interests
• Rag Chewing on Local and Gateway Repeaters
• Amateur Radio allows experimentation
• An experiment that seems to be working
• More Elegant and targeted form of networking than
• IRLP or EchoLink
• Must know users QTH and node number at that QTH
• D-STAR only requires knowledge of persons call
  sign
• D-STAR Replace Analog FM???
• Akin to AM to SSB on HF in the 50s and 60s
• Not to worry D-STAR and Analog will co-exist
  for a long time

D-ECHOAuthored By Robin Cutshaw, AA4RC

• The repeater will record your transmission and
  play it back upon un-keying.
• The application is invoked by entering repeater
  call-sign and E into the UrCall field (e.g.
  KF6BQK E).

COMMUNICATING WITH D-STAR RADIOS
21
Getting Started Local Repeater Usage

• No Squelch Tails Or Courtesy Beeps From Repeaters
• But You Do Get A Status Read Back!
• Ur Or Ur? Usually Means You Did Go Through
• RPT Or RPT? Usually Means You Did Not Go Through
• Local Repeater RPT -Try Again
• Gateway Ops RPT
• Check Your Routing Calls RPT1 RPT2 Or Local
  Gateway Could Be Down
• Remote Repeater Could Be Busy
• Short Transmission From The Repeater
• About 1 Second After Unkeying
• Be Conscious Of How Close To The Cliff you Or
  Other User May Be

22
PROGRAMMING USERs RADIO

• Lots of Memory Channels
• Many Setups Organization Of Channels Names
• Programming Software Strongly Recommended
• When You Begin To Program For Gateway Usage
• You Dont Want To Program Calls While Driving !

RADIO INITIAL SETUP - DV

• Turn on Radio
• Set Frequency as for Analog FM (Mt Woodson
  446.980 MHz)
• Set offset (0.600 MHz for 2M 5MHz for 440 )
• Decide on the Communication You Want to
  Accomplish
• To whom you want to talk
• Defined by RPT1 and RPT2
• Enter / Program Call Signs into the Radio
• Push Buttons, Turn Knobs to Alpha Numeric Entry
  Areas
• MyCall Always the Radio Owners Call Sign
  (e.g. Cecil uses WD6FZA)
• UrCall Always the Station Being Called
  (CQCQCQ, Repeater, or Individual)
• RPT1 Call sign ( port) of the originating
  (input) repeater
• (Local Repeater e.g for Woodson use KI6KQUA, B,
  or C)
• RPT2 Call sign designator of the gateway
  or cross band port
• Call Routing (Local Repeater e.g for Mt. Woodson
  use KI6KQUA, B, C, or G)

PROGRAMMING D-STAR RADIOS CALL SIGN ENTRYS

• Decide On The Communication You Want To
  Accomplish
• Simplex
• Repeater
• Local
• Same Band
• Cross Band (2M To 440, 2M To 1.2 Ghz, 1.2 Ghz To
  440 Mhz
• Another Part Of The World Via The Gateway (e.G.
  San Francisco, Atlanta, Australia, Italy)
• Same Band
• Cross Band (2M To 440, 2M To 1.2 Ghz, 1.2 Ghz To
  440 Mhz)
• Tells You What To Enter Into Urcall, RPT1,
  And RPT2 Blocks
• Eight Character Positions For Each Block
• Seven For Station/Repeater Call Signs
• Character Position Number 8 Is A Switch

28
SIMPLEX OPERATION CALL SIGN ENTRYS

• Preferred Entrys (First 7 or Fewer Character
  Positions)
• MyCall The Radio Owners Station Call Sign
• UrCall No Entry Required
• RPT1 No Entry Required
• RPT2 No Entry Required
• Owners Call Sign (MyCall)is automatically
  transmitted each time PTT is pressed
• Communications can be accomplished with nothing
  entered for MyCall, UrCall, RPT1 or RPT2

29
Gateway Essentials

• Registration Required For Gateway Operation
• Get With Your Local Administrator To Get
  Registered
• Registering More Than Once Can Mess UP Gateway
  Data Base
• Similar to IRLP Except
• D-STAR Calls Are Automatically Routed
• No Registration Required For Local Use
• Conversations Are NOT Private
• Both Ends Hear All
• User Linking / Routing, Not Site Linking
• User Determines The Route His Transmission Takes
• Program Your Radio Ahead Of Time For Mobile

Gateway Call Sign Entries

• First Decide
• With Whom You Want to Communicate
• To Where You Want to Communicate
• Preferred Entrys (First 7 or Fewer Character
  Positions for Call Signs)
• MyCall The Radio Owners Station Call Sign
• UrCall / Remote Repeater Call followed by an
  , , or
• OR The Call Sign of the Individual
  With Whom You Want to Talk
• RPT1 KF6BQK , or , or (note
  the 8 characters)
• For 1.2 GHz Repeater
• For 440 Repeater e.g. for Mt Woodson
• For 2M Repeater
• RPT2 KF6BQKG

THE CUTTING EDGE?

• Not the only digital game in town, but it works
  out of the box
• Excellent performance on 440
• ISDN rate internet access via ID-1
• Transparent call routing throughout the D-Star
  Network
• Significant experimentation and innovation is
  occurring (e.g., home brew radios, openstar.org)
