[Elecraft] K2: Diry RF Gain pot?

[Ron D'Eau Claire]

Some of those sprays are awful, consisting mostly of various oils that get
all over the place. 

Suggest using a small amount of DeOxit. The idea is to get it in on the
resistive surface, which usually means putting a few drops on the terminals
where the exit the pot assembly. 

Option is a replacement pot - generally the best long-term fix. 

Back in the "old" days, (1950s) we shot the pots with spray and sent the TV
or radio back to its customer with a minimal billing - usually 1/10th the
cost we'd have needed to charge to replace it. But here your time is "free"
- hopefully part of the fun of the hobby - so a short-cut quick fix isn't
needed. 

I suggest the chemical simply because you probably need to order a
replacement pot.
