And that slight offset could be adjusted using digital or analog signal voltage technique? Not easily, but you could use a crystal oscillator with a varicap diode to pull it a few kHz. I don't know if that would get you the range you're looking for. Some radios use a transistor and a capacitor to shift the CPU clock a bit. That way, if a harmonic of the clock oscillator will cause interference to a particular channel you can move it out of the way. I'll see if I can scan in the relevant page of a manual that shows this - I know the Motorol MC Micro has this, so if you find a PDF you can maybe do something with that. If you really wanted to go nuts with it, you could use a DDS chip. Gordon MM0YEQ
