I have a NPX-138 VHF transceiver here which I would like to use but want to tune it up on the bench.
?
I found the main oscillator and fine tuned that, and the transmit power pots were labelled so got those, but would like to adjust transmit deviation and maybe other internal pots.? I have been unable to find anything more than the installation and operation manuals online.
?
This unit was manufactured by NAT, who is now gone, but the design was bought by Cobham and other later on so is still around.
?
Anyone have any leads?? Ideally for a full service manual but an adjustments procedure manual would be acceptable.
?
TIA,
Peter
