[Drake] Carrier point adj. for TR4

[James C. Garland]

Hello Guillermo,

I'm afraid I don't understand the question. I've never used "two 
tones" to adust carrier oscillators, and I'm not sure how they would 
be useful unless they were spaced exactly at the filter bandwidth.

  Normallly, one just tweaks the oscillator frequency to put the 
carrier on the appropriate edge of the filter bandpass, typically at 
the 3 or 6 db point. The easiest way to ballpark the correct setting 
is by talking into the microphone and listening to yourself on 
another receiver.   Most transceivers also have a separate oscillator 
offset adjustment so the dial setting doesn't change when switching 
beteen USB and LSB.
