I know the 27.620 MHz (27.820 MHz input) one is still on the air.  Used to be part of a four-repeater network apparently.  I'll add it to the list.

Josh, I know that there are videos on YouTube of people sending digital modes such as ROS and PSK31 through repeaters on 27.235 MHz and 27.245 MHz.  The recording times vary from repeater to repeater, some of them are only 20-30 seconds while others are longer, up to 2-3 minutes.

I've also added the link to the Wiki page that contains more information regarding these listings.  Glad to be of help.  It didn't seem like there were any English-language lists anywhere online so I wanted to put one together.

Been listening to this for the past 10-20 minutes, seems like the UNID on 6926.5 kHz went off the air and a few minutes later this came up.  Currently relaying the audio from Relay Station 5150 kHz AM.  Lots of fading and noise, alternating between the KH6ILT KiwiSDR and the ZL/KF6VO KiwiSDR.

11 meter echo repeater CB parrot simplex repeater listing (Wiki)


After some serious research, I've compiled a list of the 11 meter repeaters operating in Russia, the CIS, the former USSR/Soviet Union, Eastern Europe and, in some rare cases, Western Europe and Northern Europe as well:


Once I do some more minor edits, I'll add this information to the HF Underground Wiki as well.  In keeping with the policy of this forum, all frequencies have been converted to kHz

Frequency Range:  25610 kHz to 27995 kHz (25.610-27.995 MHz)
Step: 5 kHz

Modulation/Modes: AM, FM, SSB.  FM is by far the most common mode.  AM is used on specific channels (the main ones being C15 and C19, we'll get more into that later).

Russia is unique in how its CB channelization is set up.  It is actually two sets of channels.  These sets are referred to be several different names, but here they will be referred to as "European" and "Russian".

The European offset, or “grid “(or “raster”) / Russian offset grid (or “raster” – also called “Polish grid”)

European grid = last digit of channel frequency is a 5 [hence the "fives"]
Russian grid = last digit of channel frequency is a 0  [hence the "zeros"]

Russian grid frequency is always -5kHz from corresponding European grid, for example, European channel 27155 kHz is 27150 kHz on the Russian grid.  Many radios now include a “-5kHz” switch to alternate between the two grids.  The -5kHz switch is often used in conjunction with the +10kHz switch common on most "export" radios.  This allows the user to get to the 5 "hidden" channels per band.  When a radio is equipped with the ability to tune in 5 kHz steps and/or is equipped with -5 kHz and +10 kHz switches, no channels are skipped and full coverage across the radio's frequency coverage is possible.  

Alphanumeric channel name, allocation is broken down into bands of 40 channels each.  Standard CB band (26965-27405 kHz / 26960-27400 kHz) is “band C”.  Other letters are used to indicate if the channel uses the European or Russian offset.  Optionally, the mode AM or FM is included in the channel name.  When operating in SSB, most operators refer to the frequency directly instead of using a channel designation or name.

Channel designation uses the following format:

Band(A, B, C, D, etc), channel #, Grid/Offset (E for European, R for Russian), Mode (Optional).  Mode is optional because most CB communications in Russia are in FM mode.  

So Channel 37 on the standard European CB band, using AM mode, that is, 27375 kHz AM..
is designated C37E AM or C37EA.  If these is no mode letter following the offset/grid designation, the mode is assumed to be FM.

The bands are designated as follows:

Band AE = 25615-26505 kHz
Band AR = 25610-26500 kHz
Band BE = 26515-26955 kHz
Band BR = 26510-26950 kHz
Band CE = 26965-27405 kHz
Band CR = 26960-27400 kHz
Band DE = 27415-27855 kHz
Band DR = 27410-27850 kHz
Band EE = 27865-28305 kHz
Band ER = 27860-28300 kHz

Operating below 25610 kHz or above 28000 kHz is forbidden, however this rule is widely ignored.  While the Russian CB allocation is technically 25615-27995 (or 26515-27855, depending on who you ask/where you look...), CB radios designed for use in Europe/Asia (where there are various different channel plans, mode restrictions, and power level legislation that varies from country to country) are often referred to as "multi-norm" or "multi-country" radios.  

These radios require the end-user to select the country the reside in (usually via a menu setting, holding down a button while turning the radio on, etc) and then the radio's software loads the appropriate channel plan(s), mode(s), and power levels for the country that has been selected.  These radios all include the European standardized 40-channel "CEPT" or "mid band FM" allocation (same as the US 40-channel CB band, only with 4 watts FM max power instead of 4 watts AM).  Many countries in Europe allow AM or AM/SSB in addition to FM, and places like Germany and the UK both have a country-specific set of 40 channels in addition to the mid band channels.  The UK has their 27601.25 kHz to 27991.25 kHz band and Germany has their "auxiliary" 26565 kHz to 26955 kHz band for a total of 80 channels.  

Of course, a clever CB user simply has to select a different country than the one he's in to gain access to these extra channels.  Further complicating matters is the fact that, in the past 2-3 years, CB manufacturers have added Russia to the list of countries you can select from.  Usually referred to as "RU mode" (Germany is "DE", the UK FM band is "UK", etc).   Some radios require the end user to snip a jumper from the board in order for "RU" to be an option.  However it's done, once a multinorm radio is switched to "RU mode", the frequency coverage generally opens up from 25615 to 30105 in 10 kHz (or even 5 kHz!!!) steps.  Power output restrictions are often disabled in RU mode as well.  

Of course, the op could also just buy a regular old "10-meter radio" or "export radio" like they do in the USA and most other parts of the world and then "convert" it to 11-meter coverage.  The frequency coverage is almost exactly the same nowadays.  The modern generation of 10 meter radios (the Anytone AT-5555 and its dozens of clones/upgrades (Alpha Max AM-1000, Superstar 9900, Maxlog M-8900, CRE 8900, Alinco DR-135CB/DR-135DX, AT-6666N, etc, etc, etc) all simply require holding down the right combination of buttons when switching the radio on.  Doing so gives the user the exact same frequency coverage, channeling and frequency steps as a legal European-purchased "multinorm" radio that has been set for "Russia".  


anyway, on to the topic at hand.



CB repeater systems:

Russia is well known for heavy usage of simplex (store-and-forward) repeater systems (sometimes called Parrots, Parrot Repeaters, Echo Repeaters, Echo Relays, RT-SRC1's or ATX-2000s).  Most repeaters simply record and re-transmit whatever transmissions they hear, while others require CTCSS tones (commonly 88.5Hz) or DTMF to open them.  All repeaters operate in FM mode. Several frequencies have more than one repeater operating at once.  Larger cities and metro areas have several repeaters available in addition to that city's agreed-upon simplex channels.  Many repeaters are located on mountain tops or on the top of high-rise buildings in cities.  

Worldwide communication is possible and has been made through these repeaters.

The vast majority of these systems are straightforward simplex repeaters.  They record a signal and then retransmit it on the same frequency.  Some are part of larger linked systems (most often crossband or Xband to the license free PMR446 and LPD433 services).  A handful of these systems actually link several 11 meter CB repeaters together for wide-area coverage or link repeaters through Internet services such as Echolink.  

The frequencies 27235 kHz and 27245 kHz are used throughout Europe (and likely Russia) for digital communications.  The most common data modes are ROS and PSK31 but other datamodes are in use.  Russian taxi cab company dispatchers also make heavy use of these systems.

I have been listening to two OMs chatting away on 6900 kHz LSB for the past 15-20 minutes.  Spanish speaking stations, with Mexican accents, talking about propagation conditions and antenna systems.  One of the operators gave his cell number over the air and asked the other op to text him.  Other topics of conversation included typical "ham-like" things such as the weather, operating conditions (radios, antennas, frequencies, names of towns/cities, etc).  Polite chatter, nobody jamming or intentionally transmitting over other signals this evening.  My Spanish is decent enough for me to understand the topic of conversation.  

These guys are most certainly freebanders and not pescadores.  If they are fishermen, they're well-versed in the world of radio.  Operators seemed to be referring to each other directly as "4778" and "hermano" (brother).  Most of the time, however, no IDs were heard at all. which further leads me to believe they're freebanders or other land-based transmitters.  

The operating habits of these stations mirror those of the 11 meter ops often heard in the 27405-28000 kHz portion.  For the most part, they are polite ops and when QRM becomes an issue, they change frequencies...or flip the mode switch to the opposite sideband.

I have a feeling these guys are related to the "pescadores" (or maybe they actually are pescadores in the case of the thread I'm linking to) sending SSTV:

Barely hearing OTR on 6770 AM but I can tell there's a carrier there.  Bits and pieces of audio heard but I can't tell what's being transmitted as far as the content.  Noisy conditions this evening.

2721
I think its different stations, the signal that popped up after 2100 was considerably stronger than what I heard from 2040-2057ish

2115 UTC - Rap song with long intro - OM (with English accent) vocals
2122 UTC - SSTV ID
2124 UTC - OM talking about being a cat (??)
2139 UTC - SSTV
2141 UTC - O Canada!
2144 UTC - Off the air / QRT

Thanks Sekio Radio!

2722
Sounded like a relay of the Relay Station 5150 on 5150 kHz AM, followed by dead carrier/air on 6925.0 kHz.  

At approx 2040 UTC, faint SSTV heard/seen on the USB on 6925, followed by another, stronger SSTV transmission.  

2043 UTC - CW
2044 UTC - More CW (stronger)
2045 UTC - Tones and beeps, sounds like a relay of CHU's time pips
2047 UTC - SSTV (I think its SSTV, its getting slammed by a very loud ute burst/rush)
2048 UTC - Faint CW, still getting slammed by ute QRM
2056 UTC - AM carrier on 6925 kHz gone
2057 UTC - More CW, followed by SSTV

10/11 meters / Re: 27.455 USB
« on: December 09, 2016, 2124 UTC »
It's a local channel in an area near where I'm located as well.  Same with 27445 LSB. 

I know I've posted about this several times before but, there's another example of an "11 meter gentleman's agreement" regarding most US-based transmissions using LSB (with 27555 USB being the big exception) and Spanish language transmissions using USB.  The problem is when some truck driver or taxicab company using AM comes screaming in on top of the SSB traffic on a given frequency  ::)

2724
Carrier fading up, hints of audio here and there at 2316 tune-in.

Nice to hear OTR this time of the evening :D

Other / UNID QSO Telephone Patch 6772.5 kHz USB 2230 UTC - 07 DEC 2016
« on: December 07, 2016, 2249 UTC »
On-going Spanish language QSO on this frequency, sounds like a telephone patch.  OM talking to a child, heard child address OM as "papa" several times.  People laughing in background at points.  

"Whurring" QRM on nearby frequency 6773 kHz nearly constant but doesn't interfere with monitoring of 6772.5 kHz USB.  

A quick scan of nearby frequencies has revealed similar "phone patch like" Spanish language communications on the following frequencies:

6671.5 kHz USB
6710 kHz USB (possibly Spanish language military traffic)  
6778.5 kHz USB

and, of course, the usual pescadore (fishing fleet and/or freebanders, outbanders, etc) booming in stronger than usual:

6732 kHz USB
6880 kHz LSB
6890 kHz LSB
6900 kHz LSB  - often hearing 6900 USB and 6900 LSB at the same time,
6900 kHz USB  - 6900 USB seems more like freebanding radio ops than fishing fleets
6905 kHz LSB
6910 kHz LSB
6919 kHz LSB
6925 kHz LSB
6930 kHz LSB  - VERY strong
6935 kHz LSB
6948 kHz USB - switching between English and Spanish (!!!)
6950 kHz USB
6960 kHz LSB

and several, possibly dozens of others.  First time I've seen/heard USB used so often.  

Considering how many other Latin American comms I've heard in the 6000-7000 kHz range this evening...this could be coming from anywhere.  

6772.5 kHz USB is just far enough away from Old Time Radio aka OTR on 6770 kHz AM (which is just a carrier with very slight modulation right now) so that there is very little interference at the moment.  If OTR on 6770 AM was stronger, I doubt I would be hearing 6772.5 USB.

2246 UTC - Tuned back in and now YL is talking to the OM.  S6 to S7 level signal strength, some fading but no problems copying.  Seems like a fairly informal conversation, possibly a husband and wife talking.  

2252 UTC - Conversation still on-going with slightly stronger signals (and slightly more QRM from OTR on 6770 kHz AM).  

2301 UTC - Still on-going, with ever increasing QRM from OTR on 6770 AM.  The signals on 6772.5 USB have increased in strength as well, however.

2312 UTC - Gone sometime between 2302 UTC and 2312 UTC.

North American Shortwave Pirate / Re: UNID 6926 AM 2103 UTC 7 Dec 2016
« on: December 07, 2016, 2236 UTC »
Heard this station when it was mixing with Radio Free Whatever on 6925.2 kHz AM (I think it was RFW) before they moved up to 6929 kHz after WPH75 went QRT.  Seemed like there was possibly a third station in there as well but that could have been SSB voice traffic from 6925 kHz LSB or 6930 kHz LSB mixing in with the various carriers. FDR's speech mixed with music actually sounded kind of cool.

I agree with refmo that the CW ID heard was "WPH75"

2727
Peskies / UNID QSO 6948 kHz USB 2210 - 2220? UTC 7 DEC 2016
« on: December 07, 2016, 2234 UTC »
Heard two stations talking on 6948.0 kHz USB, which is odd as most of the "pescadore" and "freebander" crowd seems to favor LSB for two-way communications in the 6800-7000 kHz range.  Heavy Caribbean accents (likely Jamaican) switching freely back and forth between English and Spanish.  Informal comms but was mostly in Spanish (one station was S9++ the other was barely above the noise floor).

Not sure what to make of this but since it was in USB mode and switched between two languages I figured I would post it here.  Lots of two-way activity on the band this evening on the usual 6900 kHz, 6919 kHz, 6925 kHz, 6930 kHz, 6935 kHz, etc, frequencies, but everything else was in LSB (and in Spanish only).

The communications heard on 6948 kHz USB reminded me a lot of traffic I've heard on the 27515 kHz LSB Caribbean 11 meter calling frequency.

North American Shortwave Pirate / UNID 6929.3 AM 2220 UTC 07 DEC 2016
« on: December 07, 2016, 2226 UTC »
Hearing some music and an AM carrier on 6929.3 kHz or so.  Very strong pescadore/freebander QSO going on on 6930 kHz LSB making it very difficult to copy 6929.3 AM but there is music there. 

2225 UTC - Music and carrier whine getting stronger.

North American Shortwave Pirate / Re: YHWH 4875khz 0227z 12/7/16
« on: December 07, 2016, 0322 UTC »
I've got a carrier and music right above the noise floor on 4875 kHz  Heavy QRM at times with digital roars, rushes, whistles and beeps on top of the music.  Can't really tell what the music that's being played is but there is certainly something there.

At least YHWH is using part of a broadcast band (instead of in the middle of ham bands/military bands/etc like the original YHWH).

On a side note, do we have any confirmation that this station actually is the [in]famous YHWH?  Could it be somebody relaying their programming?  Anybody heard an ID of any sort?

10/11 meters / Re: 27.455 USB
« on: December 02, 2016, 0318 UTC »
27455 USB is one of the more common Latin American SSB freeband frequencies (I mostly hear Spanish and Portuguese on that frequency) so hearing Italian stations is a nice catch!  When the band is really open 27455 USB can be one of the busiest frequencies on the "high channels" (above 27405/CB channel 40), sometimes even more congested than 27555 USB.

Next time the band is open to Europe check out 27465 kHz AM (commonly referred to as "27.465 AM" or "canale 45" by the operators that use that frequency).  27465 AM is basically the 'Italian Superbowl' frequency (compare to 26585 AM for Mexico, 26705 AM and 26715 AM for Puerto Rico/Dominican Republic/Florida and 27025 AM for the USA).
