Doug,
*I* do that all the time - but I have a purpose, to align a K2 filter
passband. In fact, I add noise at the antenna input with an Elecraft N-Gen.
When listening to any band, if the ambient noise level is high, I turn
off the preamp and even turn on the attenuator and in some cases reduce
the RF Gain. The K3 has lots of reserve gain, and will even make
no-signal band noise audible at a high level if all the controls are set
for maximum gain..
If this fact is what those complaining of a "noisy K3" is all about,
then I believe they need only to reduce the gain a bit - but some will
not believe that no matter how many times it is repeated from various
sources.
73,
