[R-390] RF Gain control

[dog]

Think I've got one of my IF modules set up pretty good, but a couple 
questions. I notice the RF Gain control has glitch at the CW end (10) of 
the control. That is when I advance it all the way up there you can hear 
a sort of thump when it goes from the resistive part of the control to 
the short. I've opened up the control on both radios I have and they're 
both the same and they both seem to operate the same. Is this just the 
way they are? I notice on an ohmmeter there is resistance until the 
wiper just all of a sudden jumps to the short on the CW end, not a 
smooth transition.

Also, I notice that AM broadcast in the 4K position sounds a bit 
distorted, but in 8/16K it sounds fine. Is this typical?

I put a 10 turn pot in this IF for the Carrier Control and boy is that 
much better.
