[Chuck aa0hw]

SETUP an SLF CW TRANSMITTER is sending at 50 wpm using 50 hertz SLF RF going to a FERRITE ROD SLF CW TRANSMIT ANTENNA - powered by a cheap class D 30 watt audio amp with the FERRITE SLF CW TRANSMIT ANTENNA hooked up to the CLASS D audio amp's output

Another FERRITE ROD SLF CW RECEIVE ANTENNA is hooked up to the laptop's mic input jack and a SOUND CARD SDR module/(mixer) converts the incoming 50hz SLF RF CW to 780hz ULF audio CW
