I'd toa bit more investigation:
1) Test YIG output (rar of 8340)
2) Test input to the YTM from the low band amp

Things to suspect: Low band AMP, heterodyne mixer and 3.8GHz oscillator.
SRD is not involved in band 0 - PIN switch is involved in band 0
I think i checked both a while ago, but will check again this evening. Thanks!
