My Week in Radio

  • outside wire broke and rehung a couple times
    • avoiding tension on it
    • cheap throwing weight from big sockets from Habitat Restore
  • my first summer of HF: May not be as exciting as past Winter/Spring
  • tape measure yagi for direction-finding/tx
    • Quansheng shows dB and S-level of the signal, so going to work nicely for direction-finding
    • found a direction-finding map application for my phone to help with triangulation: SigTrax
    • may go chasing a curious source noises in my area
    • local club is gearing up for a tx hunt
  • POTA / Field Day on the National Mall in DC
    • GRA-1900t whip with coil with jumper
      • noted resonant frequencies at each jumper fully extended, so lookup, jumper, then shorten to tune.
    • ran out all the batteries, but got the park activated
  • POTA around York/Lancaster
    • oops, tick bite and lyme disease
  • sorting all the gear for radio, electronics, other hobbies.
