[Elecraft] K3s Hearing low level rear speaker audio with SPKR+PH no and low AF set

[M. George]

Hi Don, thanks for jumping in, this isn't an issue of hearing loss, nor is
it a problem of subRX AF audio.  The problem is that the rear speaker
output on the KIO3B has audio on it after turning SPKR+PH to 'no'.  I can
sit at the radio and copy CW for example from the speaker output when there
should be NONE and the level is most pronounced from the left channel.
Bill apparently tried to get some legs on this issue a year ago per his
post.  I have AFX off by the way, it's nothing to do with AFX either.

I don't have the subRX on either.  I'll make a video of the problem this
evening.  It's not like it's a low, low AF output from the rear speaker out
(when the output should be off / zero), the output is real and it's the
main receiver output.
