The frequency for the Pips is 8275 kHz, along with about 55+ other freqs, see here:

Pips netowrk is up on multiple freqs, looks like pretty much the same freqs as last go round.

I am in and out of the house, no time to list freqs now, but made recording 4000 to 26000 kHz, so will grab them later.

See this thread for possible frequencies : http://www.hfunderground.com/board/index.php/topic,12002.0.html

Chris, do you still have a file on this signal?  If you do you might make a 20 or 30 second sound clip in USB, say 4 or 5 kHz width and around 6995 kHz c/f.  I really just want to know if this is LFM or if it is pulsed, and the tone spacing.

I have seen a similar freq and width sounder in use, mostly detectable on the west coast, but it looks like the sweep rate of this signal is much higher than the sounder I have seen.  If swept vs pulsed the sounder would be a possible fit.  If pulsed a signal I have a couple other signals as possible fits.

But really nothing in my log is a good match, they all have to be changed or twisted to fit what seems to be shown in that waterfall.

I have no idea on the 17540 kHz signal.  It has a well defined rep rate and width, but to me it really sounds like RFI of some kind.  Arguing against that is the well defined rep rate I mentioned, it does not fit with typical RFI rates.

As for the 13560.7 kHz signal, keep in mind that that is smack in the middle of the ISM band.  RFID and similar systems create a lot of sounds something like what you have recorded.  There is simply no telling what kind of sounds you will run into on 13560 kHz, but most of them are not intended for human consumption.  Personally, whenever I see a signal I cannot ID on 13560 kHz I just ignore it, I spent far too many hours in the past trying to narrow them down to a source / use ;)

This could indeed be M51, the format is about right for it.  However, the format is also about right for several Russian Navy transmissions.  And that freq has been used by the Russians in the past, it was very active with 200/1000 FSK last year.

Without a more complete transcript or a repeat transmission this will probably remain unresolved.

Several different radio types in common use include a beep when keyed or unkeyed.  If the radio PTT was being dropped between groups that would create a beep.

About S8 here, good audio, just a tad wider than 7.5 kHz, starts to roll off at 7.5 kHz with a little energy out to just short of 8 kHz.

S8 signal into the High Desert.  Audio has been good after the initial up and down.

Mrs Token IDed the station as RML before the ID, and asked "why is RML in AM, isn't he normally sideband?" when she brought a drink over to my listening desk.  Possibly I have subjected her to too much Pirate Radio.  ;)

Blue Ocean Radio with his new interval signal at 0135 UTC on 6940 USB, August 24, 2013.  BOR ID at 0139z.  About S6 here, but it is stillv ery early.  Audio is good and solid 100% copy.

T!

(edit)  Shifted to 6930 kHz at 0206 UTC.

Off air at 0456z.  Great sets RML, some really good tunes, thanks for the show.

No ID heard yet, 6935 USB, August 23, 2013, started about 0310 or so.

Sounds like a few BOC cuts about 0318.  Audio also might be Red Mercury Labs.

T!

(edit)  Changed freq in the subject line to 6935 U, where the station was all the time.  Maybe I am the one who should be on meds Dr.

(edit 2)  Station off air at 0343z, back on at 0349z, and it is RML ;)

(edit 3)  The Highwaymen song at 0439 was great.  I have that on vinyl aroundhere someplace.

Shortwave Broadcast / Re: Firedrake 13795 Aug 19,2013 1203Z
« on: August 22, 2013, 2204 UTC »
While a minority of times I have still quite often heard China double teaming or even triple teaming a station with jammers.  I have heard CNR1, Firedrake, and two versions of noise jammers all hitting one station.

The use of Firedrake is greatly reduced, but still does happen on a daily basis.  It was pretty much gone for a couple of weeks (end of April, beginning of May), and then slowly came back up to its current levels of activity.

Spy Numbers / Re: New Star Broadcast 13750 13:18 utc 8/20/13
« on: August 22, 2013, 1402 UTC »
yes they do qsl or at least they used to. they used to ask for signal reports & gave a hotmail address & a PO box # in Taipei. This was about 10 years ago. Also the correct name for the station may very well  be "star star". New in Chinese is "xin" pronounced "shin" & star is "xing" pronounced "shing" so there is some confusion about it. Chinese is such a complex language with tones making a word have a different meaning. I remember now seeing the station called "star star" about 15 or 16 years ago. Easier to just call it V13.  Here is an interesting article about the station:
 

There has been a bit of controversy in the past about this, both the QSL thing and the “Star Star” thing.

While this claim that they used to give an email address and ask for signal reports has been around a while, no one seems to be able to produce a recording of it, at least no one I have talked with or researched.  I know I have been listening to this station off and on since about 1999, and I don’t ever remember hearing anything like an email address.   The format is fairly well defined and even a non-Chinese speaker should be able to spot the addition of something like a request for a reception report and an email address, even if not understanding what is being said.

There are 4 claimed QSL cards (that I know of) associated with this station, all in the 2001 to 2003 time frame.  However none of them were done via email, all were via snail mail.  All of them are anomalous in some way, for example one QSL confirms a reception, with the right time and frequency, but states the language of the broadcast was French.  One of them verified an English language transmission on a frequency the listener had not reported. 

The general consensus seems to be that the former CBS / Radio Taipei International might have responded to the QSL reports and just issued the cards, and not whoever was actually the source of the V13 transmissions.  Based on what I have read even the owners of 3 of these QSL cards consider them “maybes”.

As for the “Star Star”, yes, that was brought up a number of years ago.  However, I have had multiple native Chinese speakers listen to recordings of V13 over the years, and every one of them has reported that the station is saying “New Star”.

If I remember right V13 was the second Chinese station to receive an ID designator from the original Enigma group (I am pretty sure the ID was assigned before Enigma 2000 existed).

They were on the air at 1200z this morning (Aug 22, 2013) on 13750 kHz.  I left the house at about 1212z and they were still on the air at that time.  Conditions were not very favorable though, they were pretty weak at only about S4 or S5.

While I cannot be 100% sure of what it is without an audio or I/Q file (and the signal is not making it to the west coast) I am reasonably confident that this is Link 11 CLEW.

You can see enough detail in Kilokat7's image to see the 605 Hz Doppler tone, the 14 DQPSK data tones, and the 2915 Hz Sync.

The other image, showing 2 mirrored streams, looks like the signal is in DSB (or possibly ISB) on 6942 kHz.
