Questions

  • WA3VEE, Ron:
    • Students are using APRS to track balloons they launch.
    • using a kenwood HT and phones to track APRS.
    • suggest maybe a beam for tracking it directly
    • What is the range of APRS?
    • Suggestions for tracking?
    • W3KZG, Scott:
      • check with Corbin, K3HXW.
    • KD3EE, John:
      • it’s packet radio, so relayed by digipeaters
      • bridged to the internet, so reliably visible on aprs.fi
      • btech uv-pro is a great, inexpensive radio.
      • seeing DC to Williamsport to New Jersey on my map here
      • I have a fixed antenna for APRS 30 ft in a tree
  • AA3LH, Leon:
    • Un-Un at the end of an EFHW, how do they get away without a counterpoise?
    • WA3KFT, John:
      • Needs a good earth ground to be the other half of the antenna
        • stake, water pipe, etc.
        • need a radiating element and a counterpoise
    • KC3RFG, Jim:
      • started with end-fed antennas
      • if you don’t install a counterpoise, it’ll use the shield of your coax as the other half of your antenna
      • choke the coax before it enters the house or gets to the radio
      • proper counterpoise helps avoid RF on the coax
    • NA3CW, Chuck:
      • he wrote an article on the 985 website
      • not all end-feds are horizontal, any vertical antenna is an end-fed
      • running low power, you don’t need to worry as much about return RF.
      • vertical whips are end-fed
      • horizontal random wire is an end-fed.
      • ground plane or radials of a vertical is a counterpoise
      • person serves as counterpoise on an HT
    • AA3LH, Leon:
      • always uses speaker-wire counterpoises with ham stick verticals
  • WA3VEE, Ron:
    • Has anyone interfaced a weather station to NOAA via APRS or via internet connection?
    • W3MOW, Mike:
      • Is this the same integration like Weather Underground?
    • WA3VEE, Ron:
      • Weather Underground and all those other services.
      • Ground Truth Weather
    • W3KZG, Scott:
      • Dylan, K3DZN, has a weather station at the house that’s all linked up.
    • KC3OOK, Bill:
      • Have you bought the Davis View weather station yet
      • It has lots of modules
      • APRS is a module, good for emergency service
      • Can run on a RPi or small computer depending how much you want to do
