digital pira pll tuning help

<< < (3/3)

radium98:
i have removed P1 and directly feed the varicap .and i self tuned the oscillator like the veronica system .oscillator of Jun is not working as frequency set on dip

radium98:
what i have done

carlos manhique:
Hi!
I think Veronica PLL system will hardly work with other oscilltors. The system is prepared to control oscillators working at half of FM  frequency. Oscillators are set for 44 to 54 MHz.
Again, you can use oscillators made by PIRA CZ: 3W or 5W type.
