985 Workbench: 2025-03-24

My Week in Radio

  • 985 breakfast
    • chatted lots of Vic and Jerry
  • pota
    • 2 parks: middle creek and state game land down the road
    • set up multiple antennas: efhw + tactical delta loop
    • telescoping antenna for CB walkie talkie
  • observed some degraded propagation the next day or 2 over the weekend
  • need to check and tune up my slim jim again

Questions

  • KC3TYX, Vic: Tried to tune into WA3KFT’s 6M net, but could only hear 1 person. What kind of antenna should he have used for local contacts like that?
    • W3MFB, Mike:
      • PVC pipe with caps and made a rigid half-wave dipole and put it on a lightweight rotor to change direction of the horizontal broadside.
      • try an omni-angle antenna (circular)
      • you may also hear better in the summer.
    • WA3KFT, John:
      • used 2 perpendicular wire dipoles thumbtacked to the ceiling in an apartment.
        • single feed point
        • omni-directional
        • feed directly with coax
        • VHF frequencies have smaller antennas
        • thicker elements give wider bandwidth (copper pipe)
    • KC3SQI, Wayne:
      • built one that looked like a hula hoop: folder 6m dipole in a loop
        • omnidirectional + wide bandwidth
        • he can lend it
    • WA3VEE, Ron:
      • double bazooka design
  • WA3VEE, Ron:
    • What’s the minimum to deploy in the field for HF, VHF, UHF?
    • KC3TYX, Vic:
      • radio, hamstick, battery
    • W8CRW, CR:
      • just his truck: it has everything for UHF, VHF, HF.
    • KC3YSM, Steve:
      • looking at plans for simple wire antennas.
        • KB9VBR pota performer on a camera tripod with elevated radials
        • going to try to build that one
    • WA3KFT:
      • handful of hamsticks
    • W3MFB, Mike:
      • for emergency in car: UHF/VHF radio, CB, G90, some hamsticks
      • tune anything with a G90
