[Drake] Carrier point adj. for TR4

[Gary Poland]

Guillermo,
   I have rarely been able to hear an exact match in noise pitch when 
adjusting the carrier oscillator, there is always a slight difference, its 
really tough to explain. What I do is unballance the carrier and adjust the 
trimmer for equal RF out in each sideband, then re-null the carrier. Try 
this then get some audio reports. When I have had a bad filter, usually the 
LSB filter, I could never get the audio pitch even close and had pinched on 
the air audio reports.
