Meter is now moving after alignment but my volatge on channel 19 is 3.2vdc channel 40 is like 3.7 vdc shouldnt it be like 4.2?

Are you referring to the VCO Voltage setting? Right to specs. FIne.

yes

your saying those specs are fine ?

You will need to connect your freq counter to TP-1 and make sure that t doesn't lose 'lock' (stays on freq - no random drifting). If the voltage is too low, it will lose that freq 'lock' on the upper channels and the freq counter readings will be random/sporadic. This will happen on ch 40 if the VCO voltage is too low. If the freq is already 'locked' with the voltage you have on it on ch 40; then you are good to go.

You can turn it up to 4.2v on ch 40. But don't take it too high past that, if you go to 5v; you risk popping the diodes in the VCO board. Some of these Chinese VCO boards are weak and will pop before that voltage; so beware!. Just make sure you keep the voltage low as you can on ch 40 and still keep the freq locked. Should be good to go.

The frequencies are all locked
