Listening on the bands I can hear a mirror image of every cw signal
about a kc away either up or down depending on the band in the KX1
receiver. It is not splatter or key clicks. I have double checked with
my K3. Those mirror image qso's are not present on my k3.
The mirror image signals are almost as strong as the primary signals.
I have transmitted 1/10 watt signals with my K3 and verified that a
"ghost" mirror image signal is present here as well. It is not
atmospherics, key clicks or splatter.
