This is STANAG 4481 FSK.  850 Hz shift, 75 bd, KG-84 encrypted.  What a lot of people call 850 Hz shift RTTY when they see it, or RATT.  However, the transmitter or the audio is very messed up, and there is a lot of noise in the passband of the transmitter.

Hello,

Thanks for sharing.  I should be able to pick up New Star from my position in Idaho since Asian signals are very strong in the morning.

How did you capture the audio/video from the Global Tuners website?

Vince, in the morning your time try 8300 kHz for V13.

Also, both CamStudio and SnagIt work well to capture screens for video.  All of the videos on my YouTube channel were done with one or the other of those.

HF Beacons / Re: Beep every 2 seconds 13560 Khz

Could be a HiFER:

Peace!

I think none of those are dead on 13560 kHz because of the noise of ISM devices on that freq.  Notice they all give 13560 kHz a bit of a guard band, if they were on 13560 they would probably be buried.

Just a thought.

Take another look, could you be missing every other beep?  I have a dasher on 6978.08 that is 0.5 sec long every 2.1 seconds.

HF Beacons / Re: beep every 6 seconds- 13874khz

« on: February 12, 2014, 1926 UTC »

Is it still there, and how short was the pulse?  Could this have been 13875 kHz instead?  I mean, was 13874 kHz the tuned freq in USB or something like that?

If it was 13875 kHz, if the pulse was very short, around one eighth of a second, then you might have heard the Pips network, reported here:  http://www.hfunderground.com/board/index.php/topic,15272.0.html

13875 kHz is a frequency they use often and the pulse repetition interval is 6.0 seconds for Pips.  If you hear what you heard again, try some of the other frequencies on the list, it hits all of them in a given 6 second period.

13560 kHz is smack dead center of one of the HF ISM bands.  This means there is no telling what kind of signal you might here there, but most of them are going to beep, boop, tweet, or trill, and most are not meant for human consumption.  What I am trying to say is that this is unlikely to be an HF beacon of any type, and chances are you will never find out the source with any confidence.

Other / Pips network up, multiple frequencies, Feb 08, 2014, 1616 UTC

« on: February 08, 2014, 1814 UTC »

The Pips Network is up again today, Feb 08, 2014, starting before 1616 UTC.  Mostly the same freqs as yesterday although seeing higher freq stuff.  Could just be conditions.  At this time (1815 UTC) all freqs are still up and active.

A listener in CO is hearing all the way down to the 3450 kHz freq very weak, probably indicating one of the TX sites is in his general region.

Looking at the double pulse on 16725 I am able to peak one on about the 070 and the other on about the 095, reinforcing two transmit sites.

I will post a list of freqs here after I have a chance to review the recordings, but it looks about the same as yesterdays list here:   http://www.hfunderground.com/board/index.php/topic,15259.0.html

T!

(edit)

A quick shot at the freqs seen here today.  Others were reported by other listeners, but this is what was heard here.  I am sure more will show up as I sift the recordings.

28800, 27450, 26650, 26500, 26150, 24050, 23100, 22600, 22450, 22300, 22050, 21150, 20250, 20175, 20100, 19650, 19300, 18675, 18625, 18450, 18050, 17975, 17950, 17650, 17475, 16725, 16550, 16000, 15625, 15100, 14400, 13875, 13325, 13250, 12025, 11300, 11225, 11150, 11025, 10575, 10050, 9225, 9050, 8975, 8825, 8275, 7700, 6725, 6550, 6225

Followup.

The pulse sent this time is the same as used Aug 26, 2013, Aug 03, 2013, Aug 02, 2013, Jul 28, 2013, and Jun 14, 2013.  It is a ~0.125 sec pulse sent every 6.0 seconds.

The frequencies used appear to be roughly the same list as those days also, allowing for some differences in what I could receive for propagation and QRM.  Some of the frequencies are in or under other signals.

After having gone over the spectrum recoprdings I have 11 more pulses / frequencies to add to the list I posted yesterday, this brings the total seen yesterday to 48.  Based on the 0.125 sec pulse sent every 6 seconds there are up to 48 possible pulses and frequencies in each network.  It would be tempting to say 48 is possible and I found 48, so that is all of them, but in reality I can tell there are 2 networks in uses in my recordings from yesterday (and almost every time Pips has been seen).  This means there are 96 possible pulses / frequencies.  We know that some frequencies are common to both networks, for example yesterday, as many times when this is seen, 11150 kHz had pulses from two different networks.  This means if every possible pulse is sent that the frequency list should be something less than 96 frequencies total, or 96 minus the number of double pulse freqs.

Additional frequencies found in recordings:

18675
18100
17950
17650
16550
16350
15625
15400
13500
13100
12450
11150  (second pulse found)

That is all for now, I am sure I will find other freqs when I play back the recordings.

« on: February 07, 2014, 1735 UTC »

totoCZ, when you find V26 on 9153 look for them on 7553 and 4283 also, all three frequencies are typically simulcast.  There is another set of three they also use, 9054 // 7345 // 4243.

V26 is preceded by first a Chinese 4+4 modem in LSB on the same freqs, then M95, normally offset 1 kHz low, and then V26.  So, if you look at any of the 6 freqs above and see the modem you know M95 and V26 will most likely follow, or if you see CW in the form of M95 you know V26 will probably be next.

There is no set schedule for V26 or M95.  But they are on pretty frequently, sometimes several times a day on each set of freqs.

No, there is no relationship between the Snake Charmer and JT65.  The tones used and the number of steps are not similar.

The Snake Charmer (not my name for the signal, Hugh Stegman dubbed it that) typically uses 32 tones, however I have seen 8 to 64 used.  These tones are typically spread across about 2 kHz of bandwidth, the specific bandwidth depending on the mode the Snake Charmer is in.  JT65 uses, surprise, 65 tones, spread over 175 Hz of bandwidth.
