MMT 432/144 Manuals
Hello all -
I recently picked up an MMT 432/144 module for cheap. It seems to work OK on receive, but seems to have very low output on transmit.
Does anyone have any manual or schematic type information for this unit? I think I have some debugging ahead and schematics, especially, might come in handy.
Thanks, Ben
I found http://g4fre.com/circuits.htm, which had some good info.
I think the last pre-driver stage is busted, which is a 2N6256... does anybody know a good replacement that is in production nowadays?
Thanks, Ben

Hi Ben,
I have the original schematic diagram of the MMT 432/144 MHz transverter and if you need it I can send a copy to you as email attachement.
