Can I use a 555 timer IC to make an amateur radio? Answered
I'm thinking about starting to do amateur radio, but I don't want to pay a ton of money for a transceiver. In theory, couldn't I use a 555 timer with a frequency modulated by a microphone to generate FM, which could then be amplified and transmitted? Just curious about it. Also, couldn't one do the same thing in reverse, just finding a way to tune a 555 or something so that it would output audio when tuned to a specific frequency from an antenna? Just a thought.
