It was very strong into here all evening (noted about 0200 on past 0306 GMT).  Sends encrypted messages in 5-letter groups.  Each message preamble has a number, a time and a 1986 date, then they go into the 5-letter cipher groups.  It comes in very strongly on my northeast beverage, weaker on all other receiving antennas.

Added to my rain static, power line noise and thunderstorm QRN this evening,  the Ghetto was pretty much unusable. I contacted a station in TX on 3800, but finally  lost him in the bedlam.  I QSY'ed over and zero beated my carrier on the CW as the intruder kept on sending, but that didn't help otherwise shitty band condx.

This same station was on 3640 a few evenings ago, and another evening was noted on 3647.5, and a day or two later had QSY'ed to 3528.5.

This station was a recent topic of discussion on the CW Reflector:

Quote
...his preambles follow sequentially this pattern for each message..

nr 38 d  04 00:52:51  1986

nr 39 d  04 00:59:07   1986

Also the time group in the preamble advances in time with my CPU clock

although his time given is one hour advanced over UTC....

The year being 1986   seems strange...

Each message is about  6-7 mins long...

Reported very strong in northeast US and eastern Canada.  The consensus is that the transmitter is located somewhere in the vicinity of NJ.

1986?
This may be a late KGB message reporting shipping  transit info in/out of New York Harbor.

I have not caught them when they first come on the air, or had the patience to wait until they signed out to see if they transmit any kind of station ID.

But if they are of US origin, what in the hell are they doing inside the amateur band?  I thought that's what frequencies like the now-defunct proposed 60m band are supposed to be reserved for, precluding any further expansion of HF amateur allocations.

Maybe they are on a ship anchored just off the coast.

Somali, maybe? Grin

Yep, that's it for sure!

And the other info is a reference to specific article and paragraph numbers in the US Constitution.  Wink

Funny that IRB would be mentioned but there almost always was a CW message, that wasn't very nice, running under the A.M. QSO's when IRB was on the air.

I hear gross body noises, and heavy burping, when Phil, K2PG is in QSO, at times.

Yah, I heard it strapping into New England last night. I never heard it before, so I simply chalked it up to weird band conditions. Hope it doesn't show up there too frequenly!

Yosemite Sam has learned CW.. So, who's doing the DF to track this one down? Is it automated?

Hmmmm, Midway Island's desalinator is kaput.  Those Brewster Buffaloes, and few F4Fs they have, are in for a rough ride when the A6Ms arrive.  Inform Yamamoto if this!

Don't worry, the FCC's RID will track it down.

Heard the CW intruder...whatever it is...this morning on or around 3881 sending: EBS EBS EBS continually in beacon fashion.  Does that stand for Extreme B S or what?
