Pots act like voltage dividers, of course. If the low side of the pot is
not electrically at ground (or some such) then turning it down has little or
no effect. Sorry that I am not familiar with your particular rig. What is
a 3140? If it is a 1430, I am not familiar with it, either, HI. I'm sure
you have tried it, but does cranking that pot fully the other way turn it up
even further?

Subject: [TenTec] T-kit 3140 side tone
I just put together a T-kit 3140. I'm quite happy with it but for one
problem:
The side tone is ear-splitting loud. I have to turn the volume control all
the way down, using the side tone in my keyer when I transmit, then raise
the volume between transmissions so as to listen to the person I'm in QSO
with.
There's a 1k variable pot inside the case that adjusts the side tone level.
I already have that at its maximum low setting. So there's something else
amiss, either with the radio or with my construction of it.
Can anyone suggest an appropriate fix? I'm new at kit building, this is my
first substantial project.
73,
