Interesting info, Julian.
During the ARRL DX CW on Sunday on 15m, at one point I heard 'ghost'
signals on HK1R, +/- 440 hz. He was quite strong here. I was listening with
a narrower than 400hz filter, and could plainly hear all three signals. My
pitch was set for between 680 and 700 hz. Some half-hour later, the HK1R
ghost sigs were gone. I was listening carefully with earphones in both
instances.

I don't know what kind of radio HE was using, so maybe this is on the wrong
reflector.

I heard no other 'ghost' signals during the contest.

I also noted HK1R's signal as having that problem.
