Mike,
It could be that the band is quiet, this is a strong signal (S7 or more)
and as you tune through to the opposite sideband the AGC is kicking up
the gain so you hear the signal down some 70 dB or so, but if it is a
strong signal on an otherwise fairly quiet band, you may hear it.

Bob, Joe, Bill & Mike,
Since I'm new to RTTY, I probably didn't describe my question in correct
terminology - I mainly only operate CW. I'll try again....
I'm using DATA A/AFSK A, setup for low tones (915/170) and the RTTY dual-PB
filter. To illustrate what I'm hearing/seeing, imagine tuning down from
14.090 until you hear and can decode an RTTY signal. Then continue tuning
down 915 Hz (to what I probably erroneously referred to as zero beat) and
then down another 915 Hz, I can now hear the same signal but inverted
(slightly weaker, but definitely there). It is not decodeable, but it is
definitely there. I assumed (yeah, I know) that the opposite sideband
should be suppresed, but I think that's what I'm hearing. Any advice will
be appreciated.

Seems strange to me. Don't or haven't noticed it with my K3S. I would
think they perform about the same in this regard.

I played a bit in the RTTY RU this weekend with my new-to-me K3 to learn
the
operation and iron out any kinks in my setup. Everything worked well
except
for a problem (?) on receive. I was able to easily tune in signals and
copy using MMTTY, but when I tuned to the other side of zero beat I could
easily hear the same signal. Obviously, it was inverted, but I was
surprised
to even hear it at all. Is this normal or do I have something setup
incorrectly?
