Mike,
Thanks for the useful tip.
The Omni VI I bought recently had a "shot" AF gain pot. The track had totally
worn at the "8/9 O'clock" position where all the action happens. Fortunately
the guys at TT still keep the spares, although I wouldn't want to do the
swap-out a second time - far too much trouble taking the front panel off :)
Spreading the "action" with your mod would reduce the wear and hopefully
prevent it happening again.
73,

Subject: [TenTec] Omni VI Audio level spread.
On every Omni VI I have had, the audio pot is only useable over 10% of its
range as it is way too loud.
I needed to check out some new filters and had the bottom off of the Omni
VI, SO..........
I put a 70 ohm , i/8 watt resistor between wiper and af min on audio pot at
connector 55 on Lower pot board.
Did this on Lower pot board as it was easiest, you could pull the if/af
board, too but I did not.
Flip rig with bottom off and front toward you.
Lower pot board is on right front...connect 70 ohms(or so) between 2nd and
3rd solder trace counting from the left.
Works like a charm. Normal audio level is at 12 o clock now instead of 7 o
clock........
I didn't have to pull any boards either.
I can only guarantee this on my rig, not responsible for yours.
Best regards.
