This is remarkable #WSPR #Beacon #ZD9SSS on #Gough Island, one of the most remote places on earth. Transmitting with 200 mW on the 80,40,30,20,17,15,12 and 10m #hamradio bands for more than 16 months with an uptime of > 95% 💪! Real #HFPropagation Data 24x7x365 Kudos @SANSA7

Harry from #Zachtek is working on a successor to his excellent #WSPR Desktop Transmitter that includes #Wifi and a reference clock input #GPSDO in order to discipline the oscillator for #spectral spread measurements #FST4W #HFPropagation Mode analysis #hamradio

Testing out the next Pico balloon payload, I’m still amazed at what 20mW will do. #ZachTek #WSPR

Got my #WSPR transmitter from Harry #SM7PNV at #Zachtek and just started the transmission from 20m to 10m. I am astonished where the signal has been heard on 20m, 17m and 15m. And its only 100 mW max because the distance between antenna and shack is 170m.

Correction, thanks to some internal Hardware mods (LPFs), the #WSPR #Beacon now also supports the 17m Band, which is 8 Bands in one device! 80,40,30,20,17,15,12 and 10m with proper overtone suppression. All WSPR Beacons will contain the modification #hamradio #hamr #hfprobing

Next Project custom-built self-contained #WSPR Beacon transmitter 23dBm on 80,40,20,15,10m based on #zachtek hardware running a custom #Arduino FW for coordinated Band hopping as per WSJT-X schedule inspired by the Intl. CW Beacon Project @IBP_Beacons #hamr #hamradio
