[Elecraft] Noisy RF gain pot?

[Stephen Prior]

Alan,

Don is right.  I thought I had done the right thing some years ago,
ordering what I thought was the same pot from a UK supplier.  I still have
it in my drawer of bits somewhere - it didn't fit.  I then ordered from
Elecraft, not stupidly expensive although the shipping always bites it
seems to me, and all was well.  (Wish I'd never sold the K2 but I had to at
the time to part fund the K3, which I still have :-)
