more. Some frequencies might be off by 100 Hertz, since i was using an
old Sony ICF-2010. Also, some were incredibly strong, others sounded
further away.

Any ideas?

Maybe a harmonic of a CODAR buoy?
Fading could be due to time of day conditions.

CODAR has more of a ping to it than these pulses had.

ALE ? Try this, let us know what it may be.

Nope, not ALE. Only one non-ping pulse every two seconds.
Sounds like slow time signals.

Very strong right now (0430 UTC) on 11709.2. Better in
USB tonight than AM.

Mike.

Just to be sure, on my end, I put the 590h on your
11709.2, about 08:00u. No time sync., I am getting a station
here. Way down, can't really pull anything out of it, but
oddball bits of music, kind of like a child's music box.??
So, sorry, no help here. I'll check a few of my ult books
later today and see if any info on this. You could ask on
one of the ult groups on yahoo, if your a member. Let me
know if you come up with anything on this, I love a good
transmitter/ station hunt.

Drifter...

Blinking Christmas lights? Take the 2010 for a drive around your
neighborhood and maybe you'll find the culprit. Who knows, maybe
they'll QSL.

Look for a new switch mode power supply in the house (they are usually L
shaped and say Efficiency 4 (IV) or 5 (V)
