XP Polytone? 7096 kHz LSB 2226UTC 17JUN13

I'm fairly certain this is some sort of a XP Polytone numbers station that I picked up a little bit ago:

Good report. I have this from your video: "7096kHz LSB at 2226UTC. Recorded in Northeastern Ohio USA 17JUN13." That is a very good report.

It should be amateur radio enthusiasts on that frequency. 7096 kHz is in the Data section of the 80 meter Amateur radio band. Keep searching there is a whole world out there you will find more interesting things :) Thanks for the report.

P.S. That does not mean you will not find odd things there in the ham bands every once and a while (I.e. Intruders) and yeah my fault I meant to put 40 meter not 80 meter band.

Pretty sure that's some ham radio digital mode, especially if it was in LSB (I would think that if would be anything else it would've been in USB, since hams are about the only ones who use LSB). And 7096 would be in 40 meters, not 80.

This is not XP Polytone, this is a ham mode.  I am not at my home computer to light off software and find out which mode it is, but it sounds like it might be either Olivia or one of the MFSK modes, my bet is on MFSK-16 or something along those lines.  Of course the MFSK modes sound very much like XP.  Check this page for some examples: http://www.k3dcw.net/index.php?p=1_4_Digital-Mode-Samples

This frequency is in a section of the ham 40 meter band that is heavily used by digital modes.  From about 7025 to about 7100, depending on the region of the World you are in, you will find MANY digital modes, often mistaken for things like XPA.  And by the way, the signals will be in USB mode, not LSB.  On the ham 40 meter band audio is most often, by convention, in LSB, but digital signals are in USB.  You 7096 LSB would also be about 7093 or 7094 USB.

Here is a good example of XPA Russian MFSK-20 (Multiple Frequency Shift Keying) http://www.youtube.com/watch?v=zrPqH3kArK4

For some background look up ENIGMA CONTROL LIST Page 27

Thanks for the information! I thought it was strange hearing something like on that on the ham band as opposed to the usual Morse code or speaking, but this clears it up.

Great find!  I have added your video to one of my YouTube playlists.

There are also examples of XPA on my YouTube channel, as well as a few other signals that are of interest to Utility / numbers / general shortwave monitors.

Thanks.  I have already included three of your videos into a playlist on my YouTube channel. You have a real knack for finding and recording the exact sort of stuff that I am most interested in. Nice work.
