[Hallicrafters] HT37 the saga continues

[Joseph Trombino Jr]

OK....so now the HT37 has pretty much full output on all bands and works in 
the CW and DSB positions (I checked the modulation and it's OK).

But the rig still puts out full output when I am in the USB or LSB position 
and switch to MOX.

I re-checked the bias and in the DSB mode the resting bias is -64.5vdc and 
when going to MOC the bias drops to the prescribed -49.5vdc.

(can anyone with an HT37 confirm these bias levels for me?)

However, in the USB or LSB position the resting bias is -64.5 and when going 
to MOX it stays at -64.5vdc instead of going to -49.5vdc.

Believe this might be preventing the balanced modulator from becoming 
"un-biased" and balancing out the carrier.

Any ideas on why the bias won't change when going to MOX in the USB/LSB 
position????

I finally have the rig in pretty good shape RF wise now and getting the SSB 
function to work is my last chore.

Any and all ideas are welcomed at this point.
