1
A Discussion RegardingExpanded High Frequency
Amateur Radio Operation at ISU

• facilitated by
• George Oster NP2N

2
Overview

• basic considerations
• license and equipment requirements
• stealth operation
• ISU club stations
• expanding HF at ISU a skeletal plan

3
What is HF?

• Radio Frequency Propagation
• 1.8 MHz to 29.7 MHz
• Amateur bands (by wavelength)
• 10/12/15/17/20/30/40/60/80/160 meters

4
Technical aspects

• all range communications
• short, medium, long range
• learning opportunity
• RF, propagation, antennas
• Media interface
• internet
• Multi mode / multi faceted activity
• technical, social, career, network

5
HF modes

• virtually all RF modes
• CW
• Telephony
• data (multiple)
• Television

6
Why HF?

• person to person communications
• a truly world wide medium
• emergency communications
• international good will
• its fun!

7
Why expanded HF for CARC?

• Emergency operations
• Community and international good will
• Expand student opportunities
• Station(s) and equipment available
• Promote ISU
• Club activity builder

8
License requirements

• Technician Plus (10 meters)
• General/Advanced/Extra (all bands)
• Future
• communicator
• entry level
• no CW
• portions of most HF bands
• expect possible current tech upgrade

9
Equipment requirements

• Transceiver
• 5 to 100 watts
• Antenna
• vertical / dipole / sloper / yagi
• Antenna tuner
• Log and QSLs
• paper / electronic

10
Stealth Operation 1

• Low power (lt 100 watts)
• Antenna
• mobile vertical (window or balcony)
• dipole (trees or attic)
• sloper
• Tuner

11
Stealth Operation 2

• Via internet
• http//www.qsl.net/oe3mzc/receivers.html
• online receivers
• http//www.lamonica.com/
• remote transmitting

12
Stealth Operation 3

• Remote control
• local station via
• internet control
• UHF link

13
ISU club stations

• Campus Radio Club
• W0YI (W9YI / 9YI)
• roots of WOI
• trustee K0NJ
• Cyclone ARC Union Drive Association
• Cyclone ARC Union Drive Association
• W0ISU (WA0KHF)
• trustee AD0H

14
History

• The Y stations granted to technical
  Universities
• 1920s as 9YI, 1YU etc.
• some remaining examples
• W0YI Iowa State University
• W1YU Yale
• W5YJ Oklahoma State U
• W8YX University of Washington
• W9YJ De Pauw
• W3YP Villanova

15
History
16
Capturing a uniqueHF opportunity

• CARC well established
• Coover remodeling
• HF mentors available
• Benefits to members, ISU, community

17
Proposed goalexpanded HF presence for ISU

• Suggested steps
• solicit mentors
• determine goals
• develop operational plan
• seek Coover space
• modify operating capability per plan

18
Proposed goalexpanded HF presence for ISU

• Beginning steps
• Formalize relationship between CARC and Campus
  Radio Club
• Define use of W0ISU and W0YI
• Solicit dedicated station space and antenna
  supports -- Coover

19
Significant HF presence

• Increased general class operators
• Training
• Operating
• contests
• field day
• university nets
• Computerized logging
• QSLs
• paper
• Log Book of the World

20
Significant HF presence

• Station
• Simple HF transceiver (e.g. Kenwood 440, Icom
  718)
• No tune legal limit amplifier
• Automatic legal limit antenna tuner

21
Significant HF presence

• Antennas and supports
• Tower
• Log periodic dipole array (LPDA) 10 or 14 MHz to
  29 MHz
• rotor
• Masts (1 or 2)
• 40/60/80/160 dipoles
• dipoles may be multiband and / or shortened

22
HF presenceOption 1

• 2 HF stations (1 with VHF/UHF)
• Friley
• low power HF
• VHF/UHF
• Coover
• high power HF station

23
HF presenceOption 2

• 2 special purpose stations
• Friley
• VHF/UHF only
• Coover
• HF high and low power

24
HF presenceOption 3

• 2 linked stations
• Friley
• low power HF station
• optional control point for Coover station
• VHF/UHF center
• Coover
• high power HF station
• optional control from Friley via UHF or internet

25
HF presenceOption 4

• 1 station in Coover
• high and low power HF
• VHF/UHF

26
HF presenceOption 5

• 1 staffed, 1 remote station
• Friley
• low power HF station
• VHF/UHF center
• control point for Coover station
• Coover
• remotely controlled high power HF station only
  (internet or UHF link)

27
Added value options 3 5

• If internet control, provides access to qualified
  members
