I have a Dosy PM-1000-TS meter that isn't reading peak or PEP anywhere near
correct. It reads less than half of what it should. Does anyone have or know
where I can find a schematic for it? Any ideas what might be bad?

Thanks,
Chris

Typical Problem , There are 4 germanium diodes in between the input and
output connectors on a small board. 2 of them are voltage dividers and 2
of them are for forward / reflected power . Most likely "1" of those
germanium diodes is open , this would give you exact 1/2 reading.

The power reading on a deadkey is OK. It's just low on the peak reading
during modulation. Would the diodes do that or could it be a capacitor?

I have the schematic, just give me a valid email addy.

do you still have the schematic i am in need of it also....got to replace my 6 position selector switch that fell apart and dont know what wires go to which tab as the board on the switch broke in to 7 pieces
