Thanks a lot for the many answers.This is what I found. 1)The carrier oscillator crystal is on 5645 KHz. 2) The SSB output on LSB and USB is the same. 3) Using my Kenwood TS950SDX as monitor there is a distinct difference on all bands between LSB and USB audio, LSB being tinny while USB being more bassy. 4) However, If I turn C2 from 12 o'clock to app. 1 o'clock, the difference is less, though still audible. 5) Considering that the frequency response in a T4XB is 350 to 2700 Hertz, it is no wonder that I am told that lows are missing in my audio. The frequency response of my Kenwood is 100 to 3100 Hertz.

If you find a difference in sound between LSB and USB, I wouldn't hesitate to try moving C2 (carrier osc freq) while listening to your signal. 73, Gary WB6OGD ----- Original Message ----- From: K9sqg <k9...@aol.com> To: 1oldle...@ix.netcom.com, fas...@privat.dk, drakelist@zerobeat.net Sent: Sat, 14 Jan 2012 16:46:27 -0000 (UTC) Subject: Re: [Drakelist] T4XB audio As a side note, the narrower the passband of the filter(s) the more critical is the alignment of the transmitter in most rigs...
