[Elecraft] K2 Excessive Internal Noise?

[Dan Barker]

On mine, (K2 #2456, Audio Pot Mod done), the radio is silent with AF Max and
RF Min. Hiss occurs (very steady, not like bacon) beginning about 2:00
O'clock on the RF and is very low level even fully CW.

It's very hard to know what amplitude you are experiencing. My o'scope says
30 mv P-P across an 8 ohm speaker in the Ext Spk. Jack with both knobs fully
CW.

At full RF, full AF, it is quite distinct.  I don't seem to recall the
"bacon frying" noise before and it is low enough that band noise will blank
it.  Also, I rarely have the AF past 12 O'clock in operation, so it isn't
apparent, but I also think that it shouldn't be there.
