Good work

Thanks Jan .
carlos manhique its best solution you are right but lots of work because its a so far design BTW i have an old sk1187 smart kit VCO i will do some experience i think it should work ,because i also tried this sk1187 with another bcd rotary coded frequency and it work .the problem i was need the same vco sk1031 or 1021 design with no need to auto tune from the pll pira only like the veronica set the frequency and lock the pll . :) ;)
carlos manhique:
Hi Jan. Would you please let me know what is the voltage output range of your PLL circuit, needed to cover 88 to 108 MHz?
As a challenge to myself, I am busy working on minimum modification of SK1021/31 to suit PIRA PLL CIRCUIT. Best Regards. Carlos

You are welcome. What type of modification have you tried so far?
Why dont you try the oscillator used by Jan on his old 3Watt TX,
