Here is another example using the LF BAND at 32Khz to send AM Modulated CW and receive it using the Rohde's AM Detector circuit plus a 2 transistor amp - to power a speaker for full volume to be heard in the whole room...
brief demo using the Rohde's AM Detector to demodulate 32Khz AM modulated CW on the LF BAND
CW Keyboard used is from RECRI KEYER https://github.com/recri/keyer
