Thanks John but I've just realised that it won't work anyway.
The receiver tunes from 118 mhz to 136mhz and the frequency meter goes from 1mhz to 50 mhz.  OOPS. :bang:

Oh well, back to he drawing board.

Roy.

John Rudd:
You could always add a prescaler to the counter....

But that adds to the complexity of things.....

RobWilson:
Cheers for the replies John R and John S  :thumbup:

I will look for a similar usb to 9v PSU  project  or maybe something to be powered from the 12v  supply on the board  :zap:

Wey aye  :thumbup:


Has your PSU kit shown up Roy ? 




I put the 0-30v PSU kit together last night  :zap:




I added the 12v cooling fan , there is a 24v output for a fan provided , I just swapped the voltage reg for a 12 v one I had .




All is good , no magic smoke  escaping  :)






NEXT !  :D




Cheers Rob
