Had a strange signal on 50.313 a couple days ago. To memory it was
centered on 1500 Hz and about 1000-Hz wide. I went about looking for
sources and disconnecting cables. With all antenna connections
disconnected it was still there (oh bad). But I also wondered if a
setting might have changed to produce it. Recently a question about
setting up FT8 on the K3 had me going thru my settings so I rechecked
them. Strangely clicking XFIL button cleared the display of the
interfering signal.
Hmm I said to myself, noting that button also controls DUAL
PB. Could activating dual-PB in DATA-A mode produce this
"effect"? Attempting to reproduce it with the XFIL/DUAL PB button
was unsuccessful (which is OK). So this remains a mystery signal
(apparently internal to the K3)?
Experts any guesses on what it was?
