Is CW just FM without an audio signal? So, If I have a FM receiver, can I install a CW audio filter and pick up CW. Such as... an IC 207H or BC 780xlt and a Vectronics CW Audio Filter. Thanks FM receivers are designed to not respond to amplitude variations. CW is about as pure an example of "information conveyed by variations in amplitude" as one is likely to find. To cut to the chase, what you propose won't work. That being said, one can send Morse in a format receivable on an FM receiver, but it'll be MCW rather than CW. Feeding a keyed audio oscillator into an FM transmitter will produce MCW. The caveat here is it is legal here in the states only from 50.1 to 54 MHz and above 144.1 MHz.
