[Wn4i]

Hello ....I bought a nice   WM1 at a Hamfest ...it dosen't work ?
I have the original schematic BUT somehow  they dont give you the schematic of the 2 Peak Detectors and Precision Divider Integrated circuits ?????
Any one can  tell me how , or fixe it for me ?.....the factory is a disaster they didnt even look at it and returned it to me for $6.00 ????.....strange ?
