[NLRS] strengthening 5760 MHz transverter

[Zack Widup]

It might be OK but that noise figure isn't very good for weak-signal work.
I built a preamp that has less than 1 dB noise figure. Also, I'm wondering
what class the power amp runs in. If it's Class A you're good. If it's
Class C, it wouldn't work well on SSB.
