audio vco
Hi!
I have a pll with a PIC and SAA1057 the frequency range is 500 to 1800KHz. I was searching for a suitable VCO for this. But it seems that most of the am vco's are with crystals.
Are there any schematics to be used with this pll?
I have found this schematic(see attachement) but this only transmits RF and i don't know how to modulate sound
Thank you
