One thing that hasn't been mentioned is that if a guy is complaining about your shack noise being heard between your sentences or even words, it simply means that your signal, to this guy, is extremely strong, and he has his AGC set too fast, so that it tries to follow the audo waveform. Inreasing the AGC time constant (setting it to "medium" to "slow") and/or kicking in the attenuator and/or turning off the preamp, or some combination of these, typically solves the problem (assuming the K3 TX really is set up properly -- not too much mic gain / compression, etc.). Guys have been amazed at how much better I sound after I tell them this. :-) Of course, approaching the issue from the K3 TX side is completely valid as well.
