Spy Numbers / North Korean V28 for month of October, 2019
« on: October 07, 2019, 1337 UTC »
Looks like North Korean station V28 has shifted operations from ~1200z (in use past couple months) to ~1300z, starting 01 Oct.  I assume it shifted Oct 01.

I had been making automated (since I am off to work before this time on week days) recordings, daily, of the transmissions on ~5150 kHz at ~1200z for a couple of months, and on 30 Sep, 2019, the station was there as expected.  On 01 and 02 Oct no transmission was captured in the recordings.  So on 03 Oct I searched and found the transmission at ~1300z, where it has been every day since.

For those not familiar with V28's habits, it is best to call them "loose".

The frequency in use can vary quite a bit day-to-day.  Today it started its transmission on 5150.6 kHz, but yesterday it was initially on 5148.7 kHz.  So to record or search for this station you have to include the target freq +/- a bit, I just record a 50 kHz wide chunk.  Also, the transmitter is drifty.  Today the transmission started on 5150.6 kHz but 6 minutes later it had drifted down to about 5150.2 kHz.

The time also varies a bit day to day.  For the last couple months the start time has been ~1200 UTC.  However most days it started about 1202 UTC.  Some days as early as 1201, some days as late as 1204.  Most transmissions have been about 6 to 8 minutes long.  There may be other time slots in use also, but the 1200 / 1300 slots tend to work best for my reception so those are the ones I tend to notice most.

This month (Oct, 2019) as I said it appears the station has shifted to ~1300 UTC, this mornings transmission started at 1304z.

So, for this month, it looks like the frequency is about 5150 kHz, and the start time is about 1300 UTC.

In addition to other time slots, there are also probably other freqs in use, even in the 1300z time slot.  I have seen this station transmitting on up to 4 different frequencies at the same time.  These are not simulcasts, each freq would be a different voice.


Apparently Puzzle Radio with Morse on 6933 kHz CW, at 2109 UTC, 4 July, 2019.

Signal is up and down, so not catching much of the Morse, but caught some clear text in plain language that mentioned THE HIGHEST STANDARDS FOR THE BETTERMENT OF ALL MANKIND and latter the signal came up nice and clean but was clearly not plain text, it appeared as random letters, I assume a puzzle.  Then caught part of an ID, PUZZLE RADIO.

Signal still there but not strong 2130 UTC.


Spy Numbers / New Asiatic M12, Mondays and Fridays, April 2019
« on: April 26, 2019, 1205 UTC »
This past Monday (April 22, 2019) at 0050z on 12137 kHz I stumbled on a new, to me, and as far as I know previously unreported, Russian M12 numbers station transmission.  The callup was 891  891  891 891  1, indicating the 0050z transmission I heard on 12137 kHz was probably the last of three transmissions that day, with earlier transmissions at 0010z and 0030z on higher frequencies, with 100's digit of 8 and 9 and last two digits of 37.

So began the hunt, each night, to determine what days this station is active.  For M12 it is common for their to be two active days per week for a given schedule.  ANd this morning I found the other transmissions.

It appears the schedule is on Mondays and Fridays, at 0010z, 0030z, and 0050z, on frequencies of 14837 kHz (at 0010z), 13937 kHz (at 0030z), and on 12137 kHz (at 0050z).

Unfortunately, we are near the end of the month, and there is only one more day this month this station should be active on this schedule, that would be next Monday, April 29.  After that it will still probably be active on Mondays and Fridays, but on a new set of frequencies, and possibly in a new time slot, will have to search next Friday to find the new schedule.

It is very likely that this Monday / Friday M12 is transmitted from the same location as the other known Asiatic M12 on Tuesday / Thursday, and the V07 on Sunday.  There also used to be another M12 from the same source on Wednesday and Saturday, but as far as I know that schedule is no longer active.


Spy Numbers / V07 new sched April 2019
« on: April 07, 2019, 0307 UTC »
April 7, 2019, 0300 UTC, V07 on 12218 kHz USB.

Callup is 254, so 0320z freq may be 11518 kHz and 0340z freq may be 10418 or 9418 kHz.  I guess we will see at those times.

V07 used to use a time slot at 0300z, however it stopped using that a bit over a year ago.  It appears it is back.

(edit)  Yes, V07 has added (or returned to) a 0300 / 0320 / 0340z slot using the freqs 12218 / 11518 / 10418 kHz.  The time slot has been used before, but I think the freqs are all new.


Keep in mind I am just a listener, and while I have worked professionally in the world of RF for most of my adult life I have never had anything first hand to do with HAARP.  The following are just my observations.

From March 26 to March 29, 2019, HAARP (High Frequency Active Auroral Research Program) conducted a series of experiments.  While an interesting radio happening, this is not particularly uncommon, occasionally HAARP shakes the dusts off and does a few days of science.

But this series had a bit of a twist over past experiments.

To do some of the science it does HAARP uses sweeping tones, stepped tones, continuous tones, or CW.  And by CW I mean Continuous Wave, an unmodulated carrier transmitted for extended periods, not Morse Code, as the term CW has become in the radio world.  And while these types of modulation are common with HAARP, they are not the only things that would get the job done.

Amanda Dawn Christie, an "interdisciplinary artist" ( http://www.amandadawnchristie.ca/about ) was closely involved this time.  And she added a different twist to the typical HAARP experiments.  Instead of the more canned techniques most often (but not always, HAARP has done some odd audio before) used in the past for Air Glow and Luxembourg types of experiments, she brought a series of art based audio and images.

The series was called "Ghost in the Air Glow".  It consisted of 10 Movements, adding up to about one hour of total air time each of the four days.  Descriptions and schedules here https://www.ghostsintheairglow.space/#home-section

Don't take it wrong, for the most part pretty standard HAARP science appears to have been done, but the content was a bit more varied than typical.

I made SDR based I/Q recordings of every minute of each transmission for all 4 days.  Unfortunately, propagation and other variables made some of the segments pretty poor recordings.  But over that time I did manage to get at least one decent copy of each of the 10 Movements.

I have converted them to video recordings and uploaded them to my Youtube channel ( https://www.youtube.com/user/FirstToken/videos ).  Any transmission involving 2 frequencies (such as the several Luxembourg experiments) are recorded using stereo sound, so that the lower RF frequency is in the left audio channel, and the upper RF frequency is in the right audio channel.

Movement I, II, and III:

Movement IV:

Movement V:

Movement VI:

Movement VII:

Movement VIII:

Movement IX:

Movement X:

A few notes on some of the receptions:

The first video, Movement I, II, and III consists of a Prelude, a poem (in Morse code), and a description (again, in Morse code) of the methodology used in the later Stochistic experiment (Movement IV).

Movement VIII is a Luxembourg event.  The HAARP array was split in two and two counter rotating beams were formed, with a rate of about 2 revolutions per minute.  You can clearly hear the mixing of the two RF channels, the Luxembourg effect, happening about twice per minute in the left audio channel.

Movement X is another transmission of Morse.  In this case a bit of a poem, but maybe a description also.  This Morse leads me to believe that there is WSPR (a low bandwidth ham weak signal digital mode) buried in the transmissions.  But I have not yet attempted to locate it in the recordings, maybe this coming weekend ;)

All recordings were  done on local SDRs, I mean SDRs physically located at my home.  Multiple SDRs were in use at any one time, typically the SDRs in use consisted of WinRadio G33DDC, WinRadio G31DDC, RFSpace NetSDR, and 2 RFSpace SDR-IQs.  However, not for any specific reason, all of the recordings I chose to convert to video came off either the NetSDR or one of the two SDR-IQs.  The antennas used were a Wellbrook 1530+, a 450 foot apex-to-apex Rhombic, and a triband fan dipole.  Again, for no particular reason, all of the recordings I converted to video came off the fan dipole.


Utility / Kids doing test counts on HF-GCS, 22 March, 2019
« on: March 25, 2019, 1536 UTC »
The HF-GCS (High Frequency Global Communications System) is an integral part of US military readiness.  For those unfamiliar, this is a US Air Force maintained global communications network consisting of multiple transmitters at multiple transmitter sites around the world.  Although the USAF maintains it, all US services, and sometimes NATO forces, can use it.  This is the radio network that transmits Skykings and EAMs, among other traffic.

Among its regular transmissions are test counts and radio tests, typically heard many times per day.  And, while the USAF personnel running the mic can sometimes sound a bit young, March 22, 2019 had some younger than average sounding voices.

I don't know if it was a command open house, or just a take your kids to work day, but two test counts in a row, starting at about 1826 UTC, were kids voices.  Whatever the circumstances it was quite cool, and a reminder that the folks making up the armed forces, all armed forces, are humans, many with children of their own.

This is not the first time kids voices have been heard on HF-GCS, but it is the first time I caught a recording of it.

A video of my recording here, unfortunately I missed the start of each transmission.


So far UNIDed on 6950 kHz, USB.  Heard first before 0255 UTC< but not sure when it first came up through the noise.

Native American sounding pipe music.


So far unided station on 6960 kHz USB.  Wide audio, looks to be over 12 kHz wide.

0211 UTC Boogie Nights.


So far unided station, 6925 kHz USB.  S7 or a bit better into the Mojave Desert of California.   Blues thus far.

Spy Numbers / V24 Logs, March, 2019
« on: March 01, 2019, 1517 UTC »

Starting a thread for V24 logs for the month of March, 2019.

My last chart is here  http://www.tokenradio.net/Radio/SharedFiles/NumbersTfer/V24_M94_latest_sched.JPG however keep in mind that is based on information ending in December.


Spy Numbers / MC03 on 5139 kHz LSB, January, 2019
« on: January 13, 2019, 1729 UTC »
Chinese military station MC03 has been active this month on 5139 kHz, LSB mode.

The transmitter is using a keyed audio tone in LSB mode, instead of ICW (keyed unmodulated carrier).  You can tell by the audio harmonics of the 500 Hz tone used.

Video of the signal here:


Spy Numbers / V24 logs, January 2019
« on: January 01, 2019, 0317 UTC »
All, the last couple of months we have had multiple V24 logging threads, and they got a bit scattered with multiple freqs / days / times in each thread.  It might be a bit better if everyone posted their January, 2019, V24 logs in one thread.   Possibly this one thread ;)

If this works out it should result in all V24 Jan 2019 logs in one easy to find place.

Here is my latest V24 schedule.  Keep in mind several of these freqs have been skipped in the last couple of months, but every time I take them off the sched they come back for a month or two.
