10/11 meters / Common and Precious III Beacon 26.510 MHz Russian SDR 20 July 2017

« on: July 20, 2017, 1739 UTC »

http://rz3dvp.ru:8073/

While not as strong as it is on the UK remote SDR, I am receiving Common and Precious III on 26510 kHz - 26,510 MHz - 26.510 MHz on the Nakhabino, Russia KiwiSDR.  S2-S3 signal, received best in CW or USB mode.  There is a Russian taxi company using 26.510 MHz FM for two-way communications that sometimes drowns out the CW signal but when the frequency is clear its nice and readable.  The Russians are all over the place (especially their taxicab communications....) so I still maintain that you made an excellent frequency choice.  Signal increased slightly around 1738-1739 UTC.

10/11 meters / Common and Precious III Beacon 26510 kHz 26.510 MHz UK SDR 1725 UTC 20 July 2017

« on: July 20, 2017, 1732 UTC »

Tuning around the 11 meter band on one of many remote SDRs, found a nice sounding CW signal right on 26510.0 kHz / 26.510.0 MHz.  Originally tuned in FM mode (signal quiets the receiver decently when transmitting, S3-S4 signal in FM mode).  Common and Precious III 26 MHz beacon 26510 kHz CW

Switched to USB mode and dropped 1 kHz down to 26509 kHz / 26.509 MHz USB mode, still peaking at a nicely readable S4 signal at 1730 UTC.

There is some very weak FM traffic coming in on 26515 kHz / 26.515 MHz and even more sporadic FM voice traffic (likely from Russia) on 26500 kHz / 26.500 MHz but the beacon's CW signal is still easily the strongest.  More FM signals a bit higher up in frequency, namely 26550 kHz / 26.550 MHz, then the start of the German CB band, at 26565 kHz / 26.565 MHz going up from there it gets busier.

Good frequency choice    That 8 watts is doing an excellent job!

10/11 meters / Re: UNID 27.385 LSB 0123 UTC 18 July 2017

« on: July 19, 2017, 1723 UTC »

Seems like a jammer to me.  With 27385 LSB though, you can never really tell.  I would presume that if somebody was trying to broadcast they would try and find a clear frequency, and stations are continuing to call CQ and transmit in general even when the music is playing. 

I sort of wonder why pirate broadcasters on 11 meters don't use frequencies like 26925 kHz or 26955 kHz.  They're usually clear (well, usually), and are easy to remember since they're both 20 MHz above the common 6925 kHz and 6955 kHz 43 meter pirate frequencies.

10/11 meters / Russian Taxis on 27 MHz Russia Taxi Dispatch 11 meters - Nakhabino, Russia SDR

« on: July 17, 2017, 2017 UTC »

The remote SDR in question is here--> [http://rz3dvp.ru:8073/]


I recently added several more European and Russian remote SDRs to my bookmarks.  The band does not appear to be open at this SDR's location.  I can barely hear the 26.945 MHz paging transmitter that is always S9+30 at http://nsk.swl.su:8073/ (which is located in Novosibirsk, in South-Central Russia).  Nakhabino is located roughly 40 miles/65km from the center of Moscow, and roughly 3500 miles/5700 km from Novosibirsk.  So the fact that I'm hearing the 26945 kHz 26 MHz paging frequency active on two SDRs that are 3500 miles away from each other likely means its like the 26 MHz UK paging frequencies, located on-site at hospitals, etc.  

After listening for a while, it became apparent that, like most places, there are local channels that most of the chatter is centered on, followed by the road channel or trucker channel...and then, since this is Russia, there's taxi cab companies (local ones) using 27.735 MHz FM and 27.875 MHz FM.  The band is closed and I'm only hearing local stuff so I bet these two taxi companies are pretty close to the receiver site.  The weaker taxi traffic could have been coming from other suburbs of Moscow or maybe even Moscow itself.  

Anyway,  here's the logs from the Nakhabino SDR, starting at 1945 UTC, ending at 2015 UTC.

Very interesting indeed.  I'm actually listening to a QSO on 2130 kHz FM (PM) right now [1422 UTC].  I've changed the title of the thread to reflect that these are legit users and not 'village radio' or freebanders/outbanders or bootleggers.

Interesting.  So chances are they're using former USSR railroad radio equipment? 

2130 kHz, 2150 kHz, both FM?  2444 kHz and 2464 kHz are closer to the other "village radio" communications that have been heard too.

Peskies / 2130 kHz - 2.130 MHz FM Russian Railroad Dispatcher Radio Traffic 15 JUL 17

« on: July 15, 2017, 1505 UTC »

I did a quick 2-4 MHz band scan on one of the Russian remote SDRs and the band was pretty quiet except for the very active frequency of 2130.  At first I thought it was distorted AM but flipped over to FM (narrow FM, NBFM, NFM, narrowband FM...roughly 9.5 kHz bandwidth) and the voices came in nearly full quieting.  I know secretsquirrel mentioned use of NBFM in addition to regular old AM and SSB for village radio...but this is the first time I've come across it.

Roundtable "net" like communications style, hearing lots of different voices chattering with each other, both OMs and YLs.  Seems like pretty informal two-way communications.  Some of the transmissions have a 1000Hz / 1kHz tone transmitted with the audio.  I'm not sure if this is part of some weird selective calling system or simply an malfunction.  Some of the transmitters have the tone, others don't.  Several times, there was no voice traffic on the channel, but the tone was there.  Almost like its serving as a "channel marker" (we know the Russians are fond of those...).

Never seen FM used in the 2 MHz band before.  There's got to be at least 8-10 different stations chatting right now, some of them are weak and others are nearly full scale and full quieting.  Anybody speak Russian?  This is the SDR I'm listening to these stations on:

Also,

Does anybody know the history of Russian / Soviet military radio design development?  I've stumbled upon some bits and pieces of information.  For example, discussions of the Red Army using British and US gear in WWII under Lend-Lease, including the famous English W.S. 19 Wireless Set No. 19 with Cyrillic labels and the American BC-348 series of HF receivers with Cyrillic labelling (called the US-9 or YC-9 in Russia) but information on Russian made radios is a little harder to find (doesn't help that I don't speak Russian).  There are some obvious nods to US, British, Australian and Italian tactical radio design in several Russian/Soviet bloc radios I've seen...for example the use of switches for 10 MHz, 1 MHz, 100 kHz, 10 kHz and 1 kHz steps for HF radios, and the use of 1 MHz steps,  100 kHz steps, and a 00/25/50/75 kHz switch for 30-76 MHz (or 20-70 MHz) FM tactical radios.  

I know about their tank and mobile command radio equipment, mirroring the WWII and Korea-era US military frequency plan of 20-59 MHz, FM mode, often adding AM, USB and CW to FM capability.  Of course, there's provision for MF/HF portable and mobile radios, and I found a Russian defense contractor's website advertising an aircraft radio that covers 30-174 MHz and 200-400 MHz AM/FM with various encryption and frequency hopping ECCM capabilities.  Doesn't explain the use of FM on the 2-3 MHz band though!  

There are lots of articles talking about Soviet-era receivers covering the frequency range in question...but I can't find much of anything on transmitters and/or transceivers.

It seems like there's a pretty wide variance between stations operating in AM mode.  There doesn't seem to be any channelization or frequency plan (at least with the AM signals).  The SSB traffic seemed to be more "channelized" - and that fits in line with military gear.  I know the Soviets operated (and the Russians probably still operate) military tactical gear in the 2-3 MHz area AM/FM/SSB and the 20-70 MHz area with FM/SSB.  When I say "FM" I don't mean the US military version of wideband (25-30 kHz bandwidth) but narrowband FM.  I've read about former Eastern Bloc / CIS countries using SSB in the lower parts of VHF in addition to the higher parts of HF (with radios that cover, say, 20-35 MHz, in USB/FM/CW modes). 

I'm checking some SDRs in that region now (just did a quick band scan of 11 meters on the Russian web SDR - now I'm checking the 1.7-4 MHz region).

Logs - starting at 1450 UTC:

2130 kHz FM - 2.130 MHz - FM - Russian voice traffic with weird polytone signals underneath
2836 kHz USB - 2.836 MHz USB - Russian voice traffic two-way QSO

Novosibirsk, Russia - grid square reference NO14 / NO14NV

Started at 1430 UTC (2130 local time at the SDR location).  Ended at 1445 UTC.  Since most export radios start at 25615 kHz (or 25610 kHz if you're using the Russian or Polish zero channel "raster"), I started at 25000 MHz just to be sure.  Yesterday I logged Russian taxi cab company dispatcher lady on 25550 kHz / 25.550 MHz FM.  Some export radios start at 25165 instead of 25615.  Others still start at 26065.  Nothing going on in the 12 meter amateur band or in the 24990 kHz to 25615 kHz area.

After doing a log with the Russian remote SDR, I thought I would use the Swedish one...and make a new thread since my other post had gotten so large:

Since the SSB traffic all was right on frequency, and the AM signals are all over the place, I decided to log the SSB traffic in its own section:

2890 kHz USB - Russian language, casual chatter (right on frequency 2890.0 kHz)
2895 kHz USB - Russian language, casual chatter (also right on frequency 2895.0 kHz)
2917 kHz USB - Russian language, with minor splatter from stronger signals on 2920 kHz USB
2920 kHz USB - Russian language, OM talking rapidly - talking to a second station...casual QSO
2925 kHz USB - Russian language, similar to other traffic heard around these frequencies
3006 kHz USB - Russian language, slightly distorted with terrible heterodyne scream QRM from AM signal on 3008.3 kHz
3040 kHz USB - Russian language,

AM two way village radio Siberian radio Russian tundra radio logs 2-3 MHz band, Russian / Slavic language...lots of frequency drift, so, as in the previous log, I am going to preface each log with the frequency I think they're 'shooting for'.  Since these AM signals are anywhere from 5-6 kHz wide to 8 kHz wide, there is some overlap and QRM from time to time.  SSB signals mixed in with AM traffic as well as various digital modes right around the 2900 kHz to 3100 kHz area in particular. 

2980 kHz AM - 2980.2 kHz, 2981.1 kHz, Russian language - pretty weak
2998 kHz AM - 2998.2 kHz - strong Russian voices, talking to a station on 2998.3 kHz
3002 kHz AM - 3001.7 kHz, 3002.8 kHz, 3003.0 kHz with QRM from strong FSK signal on 3001 kHz USB
3007 kHz AM - 3006.2 kHz, 3007.4 kHz 3008.0 kHz, 3008.3 kHz, with lots of QRM from 3006 kHz USB
3024 kHz AM - 3023.9 kHz (significant drift) and 3024.5 kHz (strong!)
3047 kHz AM - started at 3046.1 kHz, ended up at 3046.6 kHz, working a station on 3046.8 kHz (much more stable) also 3046.2 kHz
