Amazingly enough, no external preamp, just the transverter with the noise figure degraded by the DCI filter and almost a dB of coax.  That was intentional to avoid blowing the preamp up with 6m power. EME was not our chief intent....but it worked!

Yes, in a multi-op where simultaneous operation was desired.  We've run a different (100W) 6m station with the same 2m setup at the same site with much less problems (not surprisingly!).

We had it at about 300 W.

Others mentioned the antenna spacing.  We'd have put them up further apart if I could.  The site was nearly 100% treed and it was necessary to use whatever clearings were available.
