[1000mp] Low Xvtr Output

1. I think you can modify the mp, at your own risk of course !
Study the circuit - the transverter output is fed from a potential divider
and it certainly looks like you could change the values. Bet it's a bugger
to get to ?
2. Bypass the input potentiometer in the SSB transverter - that could gain a
few dB.
3. Run the SSB transverter into a small amplifier - potentially this could
give you a really good quality signal because everything downstream will be
under-run.
