Today's #hamradio adventure - installing my swap meet screwdriver antenna! (screwdriver motor extends the coil via threaded rod to tune it anywhere you want) built a new cover for the coil out of 3" acrylic, then bent up a bracket, bolted it up, initial tests are very good. Final work in the morn.

@swradiogram.bsky.social Image results from Saturday's 2300 UTC broadcast received in northern Florida, USA on 9455 kHz. WRMI had a very strong signal here today. SDR# reported SNRs over +60 dB. Using a wire antenna I was picking up some QRN and baseline was bouncing somewhat.
