I heard it on at about 5:30 PM eastern time and DF'd it.

It's coming from W3-land, SW of CT.  Similar to the episode last week.


BTW, on 3881 there is a "spy" CW station coming from NE of CT, probably located in Maine, sending 5 character groups. I will have to DF it after EU sunrise to be sure it is not from Europe.  I've heard it on and off there and on other freqs for years.... not always coming from Maine NE, however. Sometimes from Caribbean.  Used to be called the "Cuban spy" station back in the 1990's sending the same character groups.

Interesting that the WWII  German and Japanese codes were also sent in 5 character groups, both numbers and letters.  Think of how easy and "safe" it would be to blend in and  receive your instructions from a handheld shortwave RX.

the spy CW is mixed 5 letter code groups....in Europe.  Get on one of the kiwisdrs over there and much stronger.  Its possible to DF it using the kiwi tdoa function.

Sounds like the pulsing hash generator is back.

5:30 CT noise on 3885 is S8 to S9 in Chicago.   As of 5:40  pinging

I believe the 3881 CW (that is there every night) is coming from France - a CW practice station from what I've been able to determine.

Sometimes here, that CW station is the strongest thing on the band when 75 meters goes really long.

You are correct, Steve.   A simple Google search shows it as a CW training station by the French military.

I came across it when I heard you mobile last night around 3885.  The band was already going long which was a clue it probably was coming from Europe rather than Maine or VE1.

It was originally believed to be a numbers station but later classified as CW training in 2005.


[Although... wouldn't CW practice be the perfect cover in the open? All nations have spy communication schemes.  Considering how obsolete CW practice is, I don't buy it 100%.]

Hearing the CW sigs S-8 in Ohio. Five character groups with mostly letters and some numbers. Sounds like its about 25 wpm.

That's probably too fast for a spy/numbers station.
