[TenTec] Distortion SSB Omni VII

[steve r]

What element is the Heil using?
do you have a single point to ground on all equipment including computer and micro keyer. I had a similar problem and I did the following. 

Attatched ground leads on all equipment I have connected on the desk. 

EVERYTHING goes to a 3/4 inch copper waterpipe attatched to my desk with stainless steet bolts bolted and solderd to the copper pipe , then from there is 2.5 inch flat copper strap going out the window to ground rod outside at the base of the house same floor as equipment.

this helped on other rf issues as well from computer and ground hum on external radio speaker.

may not help your situation but cant hurt either.  Steve N8IS

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
