The network of CW pulses I call “Pips” in my logs has been active the last couple of days, but on higher frequencies then I have seen in the past.  I assume the good high freq conditions has driven them up a bit.

For those not familiar, some past threads on this network (there are more threads, these were just the first few I found):

The Pips network uses various pulse widths and timing sending dits or dashes on multiple frequencies.  These dits have been seen as short as 0.062 sec to as long as 3 seconds.  Pulse spacing has been seen from 3 to 10.5 seconds.  All pulse widths and pulse spacing’s within a given transmission window are constant.  The Pips are sent sequentially, normally cycling from low to high frequency.  I mean it transmits a pulse on one frequency, cycles to the next higher freq and sends another, then to the next higher for another, etc.  The pulse width and pulse spacing can be used to predict a possible number of frequencies used.  For example a 0.7 sec long pulse width spaced 7.0 seconds apart allows for 10 possible pulse positions, and apparently 10 frequencies.

There appears to be two or more sources for these Pips (I have only seen 2 that I am confident in, and so I think only 2, but there could be more).  Sometimes the two sources share a limited set of common frequencies.  This can result in some frequencies having “different” and shorter pulse spacing, as each pulse from the two nodes are on separate timing.  However, the pulses on all freqs are in sync, as on the shared frequencies the pulse timing between the two sources does not walk in relationship to each other.  And pulses on shared frequencies are always deconflicted, they never overlap or collide, and so far (on shared freqs only) I have never seen them be timed so that one starts just as the other ends, there is always at least one pulse width between the pulses from the two sources, and normally several pulse widths.  Normally out of say 32 frequencies only one or two will be shared (double pulse) meaning it is often possible to find almost twice as many frequencies in use as any one source should be able to provide based on pulse spacing.

Over the last couple days not only has the frequency been higher than seen (by me) in the past but also more frequencies have been shared.  The pulse width has been ~0.7 sec long, and the pulse spacing has been ~7 seconds, allowing for 10 frequencies for each source.  11 frequencies total have been in use (during the time periods that I have reasonable confidence I have found all freqs), with only 2 frequencies being single pulse and 9 being double pulse.

In all of the below (1) means single pulse on freq, (2) means double pulse on freq.

Oct 29, 2013, tuned to in progress at 2350 UTC, transmissions ended ~17 minutes later at 0007:30 UTC, Oct 30.

After the above transmissions the network shifted frequencies, Oct 30, 2013, up at ~0010 UTC, off 0041:27 UTC.  I only found 8 of the probable 11 frequencies, I now think they were at a high enough freq that propagation had faded for me on them (possible unfound freqs of 29388, 29555, and 29828 kHz).

The next day, Oct 30, 2013, 2150 UTC, tuned to in progress.  Continued to 2206:10 UTC.  Ended before I completed my frequency search, I had searched from 32000 kHz down to 20000 kHz before it ended, the two possible missing frequencies were likely below 20000 kHz.

10 seconds after the above ending it came back up on a new set of frequencies.  Oct 30, 2013, 2206:20 UTC to 2242:30 UTC.

28525 kHz  (2)
29388 kHz  (1)

23 seconds after the above ended it came back up on a new set of frequencies.  This set matched the set used in the last transmission sequence the day before.  Oct 30, 2013, 2242:53 UTC to 2317:00 UTC.  Not seen again after this set Looked for it off and on for the next several hours.

My log can create reports based on anything I want it to.  I should have it make an HTML table of all the freqs used, with indications of the dates and times.  This can show how this signal uses many different freqs, but also has a few it keeps coming back to over time.  For example the 4 frequencies marked as used before in the last segment above, the Pips used those back in April of 2012, but with a 0.063 second pulse width and a 3 second pulse interval.

North American Shortwave Pirate / WPOD 6925 USB 0038 UTC 31 Oct 2013
« on: October 31, 2013, 0044 UTC »
Up about 0038 UTC on 6925 USB, Bomb Iran song.  Into Benny Hill show theme, and then White Punks on Dope (WPOD) ID at 0041 UTC.  Very nice signal, well over S9.  Good audio levels, can tell there is an open mic, can hear ops yelling time to time ;)

Just in from a day of shooting and party stuff, turned the rig on and lo, someone on an odd freq.  Why, it sounds something like Red Mercury Labs, but such an odd and evil place to find him.  And then, out of the darkness, a familiar voice.  'Tis the voice of RML indeed, speaking of lost bearings, and finding themselves on the tripple 6.

You are being heard RML, but many may be taking the long sleeps.

UNID, 6940 kHz, USB, October 17, 2013, 0202 start time, S8 or a little better.  Looks like maybe the same station that was on 6925 for one song earlier...and I still say it looks like RML ;)

0202  Shoot to Thrill, AC/DC
0205  Don't COme Around Here No More, Tom Petty and the Heartbreakers
0212  RML ID, and said he was not on 6925 earlier, guess a person can't win them all.  Hey RML, they voted to reopen just one minute ago, tomorrow they will reopen the gov.

UNID station up at 0134 UTC on 6925 kHz, USB.  Looks like RML to me.

0134  I'd Love to Change the WOrld,  Ten Years After
0140  Either a very long pause or gone

UNIDed signal, S7+ here, 6940 USB.  Judging by the signal features it is probably RML, although "The Late Movie" has similar features.  I am betting RML.

0242, "Big Time" Peter Gabrial

0301, RML voice.

326
The Late Movie Show, with Movie oriented songs, 6925 USB.  Excellent audio and signal here in the Mojave Desert, California, USA.

ID at 0210 UTC.

Un IDed so far with music on 6955 USB.  Started at 0358 UTC.  About S6 into the Mojave Desert, not real strong, but music is copiable.  A voice ID might be hard to pull out if one ever happens.

0409 UTC "Too Shy"  Kajagoogoo
0412 UTC "Come Dancing"  The Kinks
0416 UTC ID, but I missed it, will have to pull out of the recording later
0416 UTC Not sure, but might be "The Impression I get" by the Mighty Mighty Bosstones
0419 UTC Renegade Radio ID
0420 UTC "Come as you Are"  Nirvana

About 0151 UTC I noticed a dasher on 9050 kHz.  This was a one second dasher that repeated every 14 seconds (1.0 x 14.0).  Looking for other frequencies I found none.  It went off air at 0158 UTC.

At 0207 UTC I noticed another dasher on 4450 kHz.  This one was a one second dash every 7 seconds (1.0 x 7.0).  I found three other frequencies, making 4 total, 4450, 7700, 10575, and 13385 kHz.  The dashes sequenced low to high.  However, since I only found 4 freqs there may have been 3 more outstanding.  These ended at 0248 UTC.

At 0249 UTC 9050 was again active with a dasher, a one second dash each 7 seconds (1.0 x 7.0).  Looking for other freqs revealed 6420 kHz also active, the pulses cycled low to high, first 6420 then 9050 kHz.  This filled only 2 of the possible 7 time slots, so there may have been other frequencies unfound.  These dashes ended at 0313 UTC.

Because of the sequencing through the freqs, and the reuse of some of the old frequencies, I think this might be related to the network I call “Pips”, even though I have not seen this specific pulse width and spacing before.

September 7, 2013, 0250 UTC

So far UNIDed on 6925 USB, if I had to guess from the transmitter I would say it is Red Mercury Labs.  Signal came on air at 0247 UTC.  At first I thought it was RML, but after a few songs it became pretty clear it probably was not.

Signal is running S8 or a little better.

0256 UTC, Sonny and Cher, "A Cowboys Work is Never Done"
0301 UTC, The Good, The Bad, and the Ugly theme...seems to be a themed show, maybe not RML, still looks like it though
0305 UTC, maybe Soft Cell, "Meet Murder my Angel", not sure though, digging for that one
0309 UTC, Elvis "Devil in Disguise"
0312 UTC, Johnny Rivers, "Poor Side of Town", really does not seem like RML music, but I like it ;)
0315 UTC, "White Room", I think Joel Grey, but not sure
0317 UTC, some kind of theme and possible ID but I missed it
0318 UTC, Paul Revere and the Raiders, "Kicks"
0322 UTC, Vikki Carr, "It Must be Him"       Possible Movie connections?
0323 UTC, Stones, "Get Off Of My Cloud"

Through the transmission the low end has faded, now getting pretty tinny.  Also fading, at 0326 is only S5.

0326 UTC, Gerry and the Pacemakers, "Ferry Cross the Mersey"
0329 UTC, new song, but faded low enough I can't make it out
0336 UTC, Gene Pitney, "The Man Who Shot Liberty Valance".  Signal is so weak I am only getting a few words.
0339 UTC, ID and Email, but far too weak to make them out

0342 UTC, Off, I never did get an ID, although I think one was sent 4 or 5 times.

Other / Pips network up, multiple freqs, 2152 UTC, Aug 26, 2013
« on: August 26, 2013, 2227 UTC »
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
