[TenTec] Distortion SSB Omni VII

["Roger Wise" <jrwise@hbci.com>]

I am using the Omni VII 588/AT.  Firmware V 1027.  Microham keyer.  WriteLog 
contest program.  Here is the problem.  When I send a contest voice message 
from the WriteLog program the audio is perfect.  I am monitoring it on a 
separate receiver.  When I transmit direct using a heil pro set/ plus 
everything is distorted.  I have broken everything down to just a dummy load 
with same results.  I can clean up the distortion by adjusting the TX 
Equalizer to a minus 15 db.   Used ddifferent mics and same results.I am 
wondering if anyone else out there has this same problem.  For the life of 
me I don't know when this problem came about.  I have run the experiment on 
low power as well as high.  I changed grounding cables and even taken them 
off.  No effect.  Any help out there.  I always had great signal reports 
about the audio before.
Thanks Roger KI0F
