Are they always there? Our washing machine generates a bunch of similar
stuff when washing.

Recently (just the last couple of days), I have noticed that my RBN
receiver is showing a far above-average number of decoders on 10M.
Investigating this, I see that *only* on 10M, I seem to have a series
of birdies. They are every 8 KHz, and are comprised of a central
signal and two weaker ones about 600 Hz either side, and vary
substantially in "loudness", although the loudest are still below S0
on my K3,
I'm unlikely to invest much time, considering the weakness of the
signals, but am wondering if the characteristics suggest some
particular kind of SPS or other device
