Hi Everyone,
I am trying to come up with an AM audio transmitter design. I've already got a few ideas but I'd like to be able to adjust the frequency anywhere from 100kHz to 2Mhz.
I thought about getting a 2MHz crystal oscillator and playing with the count to decrease the freq at discrete intervals but then I'd be limiting myself to only those frequencies. I would like to be able to "dial in" anywhere between the two limits.
Just as side notes, I plan on using a 9V battery for power and using a Pot to attenuate the power to appropriate levels.
Thanks for any help you guys can provide!
