Drakelist de PA2DW,
Last weekend I worked on the SSB quality of my T4XC. I am 90% CW operator so
I never bothered much about the SSB, but it does have a problem.
Best discribed it looks as though the bias setting is not proper. It sounds
distorted and "non-linear" and when whistling I have my full output of 160W
RF, but when talking normally into my Shure 444 the meter hardly leaves the
left corner.
I checked the bias of course, which is fine. I also checked the mic-amp and
that looks fine too. Replaced the 12ax7's by ECC83, no change.
I will proceed of course and my next target is the driver bas, but would not
mind tips and advises!
Best regards, Dick PA2DW
