Spy Numbers / V07 logs, August 3, 2014
« on: August 03, 2014, 1352 UTC »
All,

V07 logs for August 3, 2014.  As you know V07 changes time in August, moving to 0500 on Sunday mornings.

Also as normal for this station, hum and ALC issues heard on the transmissions.  Hum drops to nothing during audio, but grows in strength during pauses.

T!

Spy Numbers / V30 and M97 logs, April 16 to July 26, 2014
« on: July 27, 2014, 0100 UTC »
All,

Below are my loggings of Vietnamese stations V30 an M97 for the period of April 16 to July 26, 2014.  My last report on these stations went through April 15, something most Americans will recognize as Tax Day ;).

In this included time period I have recorded and looked at every day with the exception of June 30, 2014, for both V30 and M97, and May 26, 2014, for M97 only.  Because of my normal conditions and good in-band indicators of propagation, I believe that with the exception of those 2 days for M97 this is a complete record of all M97 transmissions made in the time period.  Because of time and propagation indicators I am slightly less sure that this is a complete record of V30 transmissions, however I think it is probably a complete record, with the exception of June 30, 2014.

Of note, while V30 still generally transmits only on days when there has been a preceding M97 transmission, the station has shown an increased tendency to transmit on days when no M97 has been present.  I have included a link to a chart to show relative transmission days.

Chart comparing V30 and M97 transmission days:

While M97 has not introduced any new messages in this time period (it is still sending the SD 85, SN 58 it introduced on August 9, 2013), V30 has had several different messages in the reported period.  

V30 message headers during the reported period:
SD 07611, SN 45 (note I erroneously reported this as 03611 in the past)
SD 77, SN 48 (although the transmitted SN is 48, message is really 178 grps long)
Unknown (signal too weak to make out details, but message length changed)
SD 04211, SN 90

Recordings are available for any day reported.

T!

YHWH on 9600 kHz, AM mode, 0408 UTC, July 18, 2014.  It sounds like he has been up for a while, but I just turned the rigs on.

(edit) Off 0435 UTC, again finished with the Op live at the mic after the recorded program ended.

YHWH was up on 9600 kHz AM, I stumbled on him at about 0330 UTC and he went to about 0431 UTC (July 16, 2014).  Normal recorded program for him, however there was a twist tonight.  A couple of times the Op stopped the recording and came on the mic live, giving his name and “a remote location in the desert”.  He mentioned HFU but said he did not have a computer to look at it himself.  He also said the station was 500 W PEP and solar powered, which is why he has odd operating times.  He gave out a good deal more information that I don't think I would have said over the air, and so I will not repeat it here ;)

KCPR up with music and CW ID at 0321 UTC, on 6925 kHz USB, July 5, 2014.  S9+ here.  Audio is pretty good, but there is an audio hum when the music dies down.

T!

(edit)  SOrry for the error, it is KCPR, not KMUD as I first reported.  I heard the CW and assumed KMUD without actually listening to the ID...DOH!

281
YHWH, 9600 kHz AM, started before 0435 UTC, June 29, 2014.  While there does apear to be some new content the majority is from previous programs, so must be recorded segments.

Off air with his normal sing off at 0511 UTC.

(edit)  Checking remotes has an excellent signal into Vancouver Canada, still fair but less strong into Michigan and Rochester NY.  10 to 20 over S9 here locally.

(edit 2)  Checked the Twente SDR remote in Netherlands.  The carrier was detectable, naturally this means it could not be confirmed as the same signal.  So when he signed off I was watching the signal on Twente, and sure enough carriers dropped on that remote and locally at the same time.

Odd Time tick station, June 17, 2014, to June 18, 2014, multiple frequencies.  And no, these are not RFI or anything like this, the signals have propagation and are heard across wide areas.

In early May, 2014, nickcarr in the #wunclub chat reported hearing an odd time tick station on 13159 kHz.  The station never gave an ID and never had a minute indicator in the audio, just even, rhythmic, 1 second pips.  Unfortunately I was working a heavy schedule at that time and really never had a chance to pursue the station much.  I did get to record it on May 4, 2014, from about 0001 to 0101 UTC, at which time it went off air.  

The center frequency of the station was 13159.58 kHz, and the time ticks were AM.  There were spurs that appeared unmodulated + and – 3 kHz from the carrier.  I am not saying they were unmodulated for sure, but if they were modulated I could not hear anything on them.  The time ticks were about 5 ms in length, or about the same length as WWV and WWVH time ticks.  The ticks seemed to start a few ms after WWV ticks did, but I did not get a good measurement on that.

And then the 13159.58 kHz signal stopped sending and I have not seen it since.

Fast forward to last night.  The Pips ditter network was up and I was searching frequencies, when I ran across an every second time tick occurring on 17179.18 kHz.  Looking closer at this signal I realized there were spurs each side of it at 3 kHz, and I mean 3 kHz down to the Hz.  The time ticks were again about 5 msec.  I checked 13159.58 but no sign of it there.  So, the signal was back but on a new frequency.

While recording it I noticed several other frequencies that appeared to have the same signal.  All totaled I ended up finding 45 frequencies associated with this signal.  20 of them had time ticks on them and 25 did not show detectable time pulses.  Of the 25 that did not show time ticks several may have had audio, but were too weak to be sure.  It is conceivable that every frequency had the time ticks, but some were just too weak for me to make out.  All of them were mathematically related to other frequencies found by 3, 87, or 90 kHz down to less than 1 Hz deviation.  17179.18 kHz seemed to be the key frequency, with the others distributed around that in various patterns.

I watched and recorded the signal on multiple frequencies from 2337 UTC on June 17, to 0101 UTC on June 18, 2014, when the signal abruptly left the air on all freqs.  Not that this is the same shutdown time I saw on May 4.  At various times in that time period it faded up and down, from very strong to weak, and I got the impression the power level was not constant, as if the level variation might not have been propagation related.  I was able to compare the arrival time of the pulses on this signal with the arrival time of pulses form WWV on 5000 kHz.  They arrived within 1 msec of the WWV pulses.  This has little meaning in and of itself, but if the pulses are sent in sync with WWV then the path distance from the transmitter to me is within 200 km of the distance from me to WWV.

In the following list of frequencies the ! means it appeared to be a primary signal.  This was a strong signal with spurs around it.  The * indicates there was no detectable audio.  If there is no symbol after the frequency that means time ticks were detectable, but it was many dB down form the closest “primary” signal, possibly some kind of spur.

The numbers to the right of each frequency are the offset from 17179.18 kHz.

Today the signal seemed to come up about 1440 UTC, I am unsure if this was propagation bringing it up or if that is when it came on.  There has appeared to be abrupt changes in signal level, looking much sharper than propagation fade up or down, this appears to be a step function.  At times the signal has been strong, and other times it has been undetectable.  While I think it has been on continuously since then (it is now 2245 UTC) I cannot be 100% sure of it.

Anyone else catching this thing?

HF Beacons / Dasher, 6954.85 kHz, March 29, 2014, 0025 UTC
« on: March 30, 2014, 0038 UTC »
Frequency is 6954.85 kHz, and does appear to shift over time.  Dashes are about 1.3 seconds long and happen about every 2.05 seconds, dash length and rate does appear to drift and wander.  At times this one and the dasher on 6954.7 kHz look like they are in sync, but if you watch them long enough it is clear they are not.
