FYI to the list: At the suggestion of Andy W3LI I disconnected the coax
at the Orion's antenna terminal. No tone. Connecting the antenna
directly to the Orion (without the usual stuff in between, tuner and
switch) got the tone again. I guess that suggests it's something unique
to my station. This isn't a huge deal but sometimes in contests it makes
copying someone difficult.

Is any other O2 user detecting this? I was going to call it a
heterodyne but that might not be the right word... just a steady
CW-like tone. Using LCW and tuning up, it first becomes audible (to my
ears) about 7030.100 and I can last hear it at 7030.700. On 20m, the
audible tone is 14030.060 to 14030.700. It's plenty strong enough to
interfere with CW signals on this popular frequency. I do not hear it
on 80m or 10m.
