Although the manual doesn't say so, according to an ARRL review, the K3S is
specified to have undesired sideband suppression of >50 dB. ARRL claims an
optimistic >70 dB.
So if you are extremely strong at the other guy's place, he might easily hear an
opposite sideband, even though your radio is operating correctly. Ask him what
the ratio is.

I received a note this morning advising that I should check my ALC as he
is seeing some energy on USB when I check into a 75m voice net on LSB.
I am using an MC-50 microphone and am running the mic gain at 35 and the
compression at 11. My thinking was that generating opposite sideband
energy would be quite difficult with the K3's DSP. Am I wrong?
I'll try working with him some morning and back down the mic gain a bit
and see what that does for him.
