UNIDENTIFIED. 11222, May 2 at 0516, regular series of pulses, slow enough to count, as the number of pulses between pauses is continuously changing. Not pure carrier CW, but ``fuzzy`` with some modulation so you don`t really need BFO to hear it, but it helps. Pinpointing frequency also difficult, somewhere around 11221-11222.
Is this some different kind of ``numbers`` station? Instead of real Morse numbers or `cut numbers` with letters substituting, just count the number of pulses each time. But unbroken series of pulses go beyond just 10, as many as 25 during the few minutes I copied them all; representing alfabetic letters, then? But most of the pulse groups are in the low-single-digits, which doesn`t make sense for that. Here`s what I copied from 0516 to 0520 or so:
2 - 7 - 4 - 2 - 2 - 1 - 1 - 10 - 2 - 5 - 2 - 6 - 2 - 5 - 8 - 4 - 1 - 7 - 2 - 7 - 6 - 16 - 8 - 1 - 3 - 5 - 12 - 3 - 4 - 9 - 6 - 1 - 1 - 2 - 17 - 1 - 4 - 6 - 2 - 10 - 1 - 4 - 1 - 16 - 16 - 16 - 5 - 13 - 3 - 7 - 1 - 14 - 4 - 6 - 7 - 1 - 3 - 2 - 4 - 1 - 6 - 3 - 1 - 1 - 10 - 5 - 1 - 10 - 11 - 2 - 5 - 2 - 3 - 25 - 8 - 5 - 2 - 5 - 4 - 6 - 8 - 13 - 1 - 1 - 7 - 10 - 1 - 4 - 6 - 4 - 1 - 4 - 2 - 1 - 1 - 2 - 3 - 3 - 6 - 11 - 2 - 1 - 3 - 2 - 2 - 1 - 7 - 13 - 3 - 18 - 6
Can anyone decode that? I did not pay attention to where some longer pauses were, perhaps separating these into groups. Steady strength and probably not too far away, altho the 11 MHz SWBC band was open from Europe, Africa, South America, New Zealand. Also British VOLMET on 11253-USB. Recheck at 1210 UT May 2, it`s still there with the same thing, also at 1314, 1353.
Then searching on 11222 in the UDXF yg, we find 23 messages so far about this since May 1, heard from Europe to eastern North America to New Zealand, subject ``Pulsing "frog" signal 11222Khz LSB``, including:

Nils Schiffhauer, DK8OK: ``should be 11.220 USB, TE-204/USC-11 modem of US Air Force; measured baud rate of 150 Baud, four channels (Signals Analyser). See also:

Mike Chace-Ortiz: ``It sounds like a broken USAF TE204 4FSK modem. Rarely heard these days``
Paul V. Zecchino, Manasota Key, Florida: ``Sounds even better on 11,220 USB, often used as secondary to 11175. Perhaps the airman forgot to break down the data link after phone patch was complete? Very strong at FL Gulf Coast QTH, within 150 miles of Cape Canaveral/Patrick AFB, etc.``
Brodyflavin: ``I haven't tracked this much today, but for those of you who have what are the max number of buzzes heard in a series? It would be stupid to do it this way, but im wondering if a number of buzzes corresponds to a certain letter or number? We'll never know for sure, I know...``
Nils, DK8OK: ``found also this info:
http://signals.radioscanner.ru/base/signal82/showing this signal in full swing and not seemingly distorted as now on 11.220 kHz``
Tony, Maidens, Scotland: ``I reviewed this very book in March in my blog and did put a link to it on here, obviously it was missed by some of you – much like Nils email ages ago describing exactly what the signal was!! The link to the review is:
