[Elecraft] K2 AF noise level?

But is it the AF amp?  I *think* (not sure) that I did a test with my
K2.  Listen to a dummy load and hear the hiss.  Turn down the RF gain
and the hiss goes away.  I KNOW that was the case with my Omni V and I
*think* that's the case with the K2 as well.  If that's true, then the
hiss is from the IF stages and changing the audio amp will do little.

Of course, I could be wrong.  Wouldn't be the first time :-)

After you've done your mod, please post your results.

73 / 72!

One source of noise is in the K2 audio amplifier.  It isn't much of a
