  1. A Discussion Regarding:Expanded 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 QSL’s • paper / electronic

  10. Stealth Operation 1 • Low power (< 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 • 1920’s 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 goal:expanded HF presence for ISU • Suggested steps • solicit mentors • determine goals • develop operational plan • seek Coover space • modify operating capability per plan

  18. Proposed goal:expanded 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 • QSL’s • 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 presence:Option 1 • 2 HF stations (1 with VHF/UHF) • Friley • low power HF • VHF/UHF • Coover • high power HF station

  23. HF presence:Option 2 • 2 special purpose stations: • Friley • VHF/UHF only • Coover • HF high and low power

  24. HF presence:Option 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 presence:Option 4 • 1 station in Coover • high and low power HF • VHF/UHF

  26. HF presence:Option 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
