[TenTec] Omni 6+ keyer instability

[Peter Inskeep]

The keyer speed control knob on the Omni VI Plus (not sure about other versions) is very "touchy."  I found that my "comfortable" keying speeds were in a very narrow range, perhaps between 10:30 am and 12:00 on the knob.  

I put a 4k ohm resistor across the keyer speed pot wiper arm, the middle one, and the arm closest to the outside of the chassis, which would be the left side when one is facing the rig.  I believe that these are the same two pot arms that the cap in the tentecwike mod refers to.  I did not find out about the tentecwiki mod until after I soldered the resistor in, but I plan to do that mod as well soon.

Only the top of the rig has to come off to do this.  The pot is clearly visible and easily identifiable, as it is attached to the keyer speed knob. (sic.).

Of course, who knows what terrible damage the above suggested mod could do to your rig, so I take no responsibility for anything that might happen as a result of attempting this mod.
