Simulating a Class-E WSPR amplifier in LTSpice. I don't like those litte spikes on the output (green), but I need to see what this would look like with real components. Plus there will be a low pass filter after the output. #WSPR #HamRadio The circuit is from this guy: https://t.co/CeATYzLoXs

🚀 Just finished building WSPR dashboard designed specifically for antenna testing!Unlike standard maps, it calculates Normalized SNR ($SNR - Power$), allowing for fair comparisons between different power levels. https://t.co/SocSXrDTl2 #hamradio #WSPR #Nextjs #AntennaTesting #SWL #RadioAmateur

🔴 I've launched the #QMX in #WSPR beacon mode. I'll be leaving it on the 21 MHz band for a long time now. The spots from Australia are encouraging. #hamradio #qrplabs #amateurfunk #DX

Another day of #WSPR joy, yesturday changed from 30 to 40m for 24hours. Amazing at what distances these waves travelling 😃 Been spotted today by @vy0erc in #ER60tb grid. 200mW and InvVee dipole 10m a.g.l Maps credit https://t.co/OLxtX2vshA

Adding, anything flying leaves a turbulent_wake that's detectable with a low-ish frequency bounce off the ionosphere, #WSPR uses a very low-freq, it could add the higher band to detect more This can detect hypersonics below the horizon 700km-1000km depending on conditions if ever it's convenient, mockup of a unit, takes about 8 units to defend USA west coast by modelling Fwiw
