985 Workbench: 2026-01-19

My Week in Radio

  • at breakfast, I showed off a USB adapter to use a CW key on the computer to chat online or play video games to practice CW
    • I’m quickly improving my score as I practice.
  • helped install antennas today at field day site
    • see the seasoned pros in action
    • afterward, I visited Micro Center, since I was relatively close

Questions

  • W3MFB, Mike:
    • Everyone checking in, sounded clear. WA3KFT, John, clicks in and out on his Anytone rig. Why?
    • WA3KFT, John:
      • 100W into the cable
    • NA3CW, Chuck:
      • WA3KFT is badly deviated, needed to turn down audio when receiving.
    • AF3Z, Jim:
      • As Chuck said, WA3KFT, John is loud.
      • Can hear everything just fine, no cut-out, so that may be Mike’s rig.
    • WA3VEE, Ron:
      • Mike, do you have the ability to set narrow/wide?
      • Delaware City UHF repeater exhibits clipping
    • W3MFB, Mike:
      • has deviation set to wide
      • Yaesu hears John just fine.
      • AA3LH, Leon, is always loud, but OK.
    • W3KZG, Scott:
      • google that radio and the problem. there are settings to adjust to mitigate it
  • W3MFB, Mike:
    • Does anyone have any experience working aurora on 6M? There’s a flare coming tonight.
    • WA3VEE, Ron:
      • a couple years ago when solar cycle was lower, he made a few contacts.
    • More people should use 6M.
  • AF3Z, Jim:
    • Has anyone heard anything much about the effecst of solar flares today around 1pm?
    • W3KZG, Scott:
      • forums complaining about bands being totally dead, even up to 2M
    • W3MFB, Mike:
      • 10M and 40M were noisy around 4pm
      • 80M has some people, and is pretty clean right now
    • AF3Z, Jim:
      • a K3Y operator was struggling to pull people out of noise
      • one station would be clear, then another like a spark hash
      • Jim heard warbling tones
  • WA3VEE, Ron:
    • Antennas were cut long, then installed, we tested, then adjusted. What’s the formula for determining the amount to trim?
    • NA3CW, Chuck:
      • SWR guesses were just good guesses.
      • For adjusting the length of the dipole: “tuning your dipole, second time, every time”
      • lots of things affect resonance:
        • height
        • quality of ground
        • insulation
        • wire velocity factor
      • to adjust:
        • measure before you put it up, while long
        • install it
        • measure where it resonates
        • corrected length / original length = desired freq / resonant freq
  • WA3VEE, Ron:
