North American Shortwave Pirate / UNID 6932 USB 0150 UTC 22 February 2020

« on: February 22, 2020, 0156 UTC »

So far unided station on 6932 USB, started with some male voice speaking, was too weak to make most of it out.  At about 0154 UTC went to music, got that fair to usable.  About S5 into the Mojave Desert of California tonight.

(edit) 0158z SSTV was Carpe Noctem, Seize the Night.  Might this be the name of the station?

(edit)  0218z deep and long fade, down to S3 or less here, I can tell it is still there, but weak.

Spy Numbers / Extended Buzzer breakdown and message, 17 February, 2020, 1241 UTC

« on: February 17, 2020, 1438 UTC »

The Russian Buzzer, ENIGMA ID S28, on 4625 kHz, is currently in one of its extended breakdowns.  They periodically happen and can cause a splash within certain communities when they do, certain doom porners really run with it.  Since at least 0130 UTC this morning, 17 February, 2020, and as of the time of this posting, 1430 UTC, the Buzzer has not been sending its normal periodic buzzes, instead it has had a deep transmitter hum.  Several times in that period the normal, or a relatively normal, interrupted buzz has returned for short periods, always to give way to the transmitter hum. 

At about 1240 UTC I tuned to the signal to see if it was still malfunctioning.  I happened to have caught one of the S28 messages the Buzzer periodically transmits.  After the message it returned to the same broken transmitter hum.

North American Shortwave Pirate / Ball Smacker Radio 6950 AM 0147 UTC 08 Feb 2020

« on: February 08, 2020, 0151 UTC »

So far unided station, or I have not heard one, on 6950 AM.  Playing at least a portion of the song Wildfire, sounds to be a repeating bar from that song.

Heard starting about 01473 UTC, on 6950 AM, Feb 08, 2020.  About S5 into the Mojave Desert tonight so far.

I assume this is the interval signal for the upcoming Ball Smacker Radio transmission, if so I will change the title on first ID.

Music change at 0200 UTC into 80's rock.

« on: February 02, 2020, 0049 UTC »

So far UNIDed station playing music on 4103 kHz LSB, I noticed about 0044 UTC on 2 February 2020.  Right where a person looking for the Windy Beacon would be sure to notice it.

(edit)  0051z Zeke heard.

HF Mystery Signals / Pips Network, multiple frequencies, 0905 to 1020 UTC, 29 January, 2020

« on: January 29, 2020, 1049 UTC »

Was insomniac this morning, so had a chance to radio at hours I normally don't

And I ran into what appears to be the sequencing frequency Pips Network that has been reported on these forums in the past.  In this case it seemed to be a 0.25 second long pulse every 7.5 seconds (the most common seen is a shorter pulse, often about 0.125 seconds every 6 seconds).  A possible anomaly with this set of transmissions is that the pulses looked like they may have been doubled, I mean two back to back pulses on each freq.  Among several possibilities this could be a phase shift in the middle of the pulse (BPSK for some reason) or it could be two transmissions on each freq.

As is indicative of this network the pulses sequence through frequencies, low to high.  However, another anomaly, in this case each frequency seemed to be pair, in time, with one other freq.  I don't think I have ever seen this before.  For sure in the past there were two networks working together, synchronized in time and sometimes overlapping on one or more frequency, but never, that I remember, with paired (coincident in time) frequencies.

What I mean is that in the following list of freqs 2000 and 2275 kHz were transmitting at the same time, and then the signal sequenced up to the next higher pair, 2575 and 2800 kHz at the same time.  And then up to the next pair, etc.  Typically in the past it would have been more along the lines of sequencing 2000, then 2275, then 2575, then 2800, etc.

Freqs observed:

2000
2275
2575
2800
3150
3550
4200
4525
4800
5400
5775
6375
6700
7050
7450
7725
7950
8275
8575
8700
9375
9600 ?
9950 ?
10250 ?

The last freqs (with the ? marks) may have shown up just before the signal ended, I have not had time to confirm they are related in time but they looked like they possibly were.  I have not had time to go through my recordings and see if I can locate other frequencies I might have missed.  I suspect there were more frequencies in use at the high end, however propagation above 8000 kHz dropped of very quickly.

Eventually I will go through the recordings and confirm the timing of all freqs, probably locating one or two more I missed under other signals in the process.  I want to see if the pairing of freqs holds up across the entire working set.

HF Beacons / Beacon HI 4094.0, 1400 UTC, 26 Jan 2020

« on: January 26, 2020, 1427 UTC »

Beacon sending HI about every 9.6 seconds, 4094.0 kHz, 1400 UTC, 26 January, 2020.

This beacon has been on this freq a couple of days, not sure when I first noticed it.  For sure it was not there (at least not heard here) last Saturday as I have recordings of this chunk of spectrum from that night.  However last night I realized I did not have it in the log, and a little further research seemed to indicate it was a new beacon.  Possibly just a beacon that has changed freq, since there was a previous HI on 8009 kHz and other freqs in the past.

The freq is pretty tight, but does change a bit.  In the last 24 hours or so I have seen it anywhere from 4093.95 to 4094.06 kHz

North American Shortwave Pirate / Wolverine Radio 6935 and 4065 USB 0100 UTC 12 Jan 2020

« on: January 12, 2020, 0102 UTC »

Testing 1 2 3 can anybody hear me @0100 UTC on 6935 kHz, USB.  Good signal into the Mojave Desert tonight.

Wolverine Radio ID just before music starts @0102z.

Wolverine announced move to 4065 kHz at 0104z.

"Testing 1 2 3 can anybody hear me" on 4065 kHz USB @0106 UTC.  6935 kHz was a little bit better for me, but 4065 is decent also.

Latin American Pirate / AD149 Radio ? 6934.9 AM 0050 UTC 29 Dec 2019

« on: December 29, 2019, 0059 UTC »

A so far UNIDed station has been up and down a few time, with a few songs, on 6934.9 kHz AM since maybe 0040 UTC.  Signal has been weak, but I have heard music.  At 0054 clearly heard Kiss's "I was made for loving you".

North American Shortwave Pirate / Station 10-100 6953 USB 2310 UTC 24 December 2019

« on: December 24, 2019, 2318 UTC »

So far UNIDed station on 6953 USB.  Started with Walk this Way, then into a 10-100 SSTV transmission.  Nice and strong into the desert tonight.

Getting hammered by OTHR right now though.

IDed as 10-100 @2320 UTC.

Hard fade, from excellent copy to almost unhearable, about 2325z.

Here is the SSTV that went at 2313z or so.

Spy Numbers / V24 error transmission, 11 October, 2019, 4925 kHz

« on: December 16, 2019, 1635 UTC »

South Korean numbers station V24 is one of the last numbers stations that uses a very traditional format of a musical introduction to every transmission.  While this used to be a common practice, today only a few stations still do this.

For those not familiar with V24, for V24 a given song is used on a given frequency, each frequency, and time slot, has a unique song associated with it.  Each message, and song, is repeated 3 times a month, on 3 different days.  The next month the same song will be used in that given time / frequency slot, but the message will be new.

In October the operator apparently made a mistake and selected the wrong recording.  11 October, on 4925 kHz, should have been the first of 3 days using Dvoracs Slovic Dances, Opus 72, No 2, as its intro song.  Instead, they played "Me Gustas Tu" which had been used on the 3rd, 5th, and 7th of the month on 5290 kHz.  In fact, the whole transmission, both the music and the coded message, was a repeat of the earlier in the month transmissions.

Here is that transmission:   https://www.youtube.com/watch?v=hHP1cjIOV5g

Spy Numbers / V07 for Dec 2019

« on: December 01, 2019, 1356 UTC »

It appears that V07 has been stable in frequency (no new freqs or times) for the last couple of months, possibly they are finished with their schedule changes.

So, V07 logs as received at my location Dec 01, 2019.

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.
