[Elecraft] K3 receiver noise questionable test results

[James Sarte]

Greetings Al et all,

In my case, I experience a significant amount of high-frequency white noise.
I'm not sure if that's the best way to describe it.  Think of the
high-pitched whine you'd hear if you're travelling inside an airplane.
Adjusting AGC, gain, and even RX EQ settings don't have much of an effect.
If anything, adjusting AGC and gain controls just seem to reduce volume but
not actual audio characteristic.

Help me out here: are we talking about the *amount* of noise, or the
*character* of the noise? I don't even think we've established the answer to
this.

If it's the amount of noise that folks are hearing, wouldn't you just turn
the gain down to match your Other receiver? No two receivers have the same
amount of gain, and I think this point has been lost on some of us.

If it's the character of the noise, and if you find it objectionable, and if
no settings of gain, filtering or noise reduction change it, I'd say
it's time to go back to the Other receiver, and I'm not being facetious
about this.
