Ok, Don and the gang. I'm back from vacation and made some measurements. I measured the S/N using the XG2 sig gen on 14.060, agc off, mode CW, BW 700 hz.  All measurements at 1 uv.  Here are the results:

Preamp off:  S+N/N = 23db (mds -129)

Preamp on:  S+N/N = 29db (mds -136)

So, what do you think?  Are those numbers in line?

(Still sounds noisy to me, hi)
