Carrier has been on 6925.0 kHz for a little bit now, wither another carrier a bit below it.  Possibly Liquid Radio?  

EDIT 1822 UTC:

Carrier moving around (VFO swooshing!) for a bit, then disappeared around 1823 UTC.  So maybe not Liquid Radio after all?    :o

OM talking about "Draining The Swamp" and El Nino weather patterns.   

1458
Came on shortly after Amphetamine Radio signed off.  Bits and pieces of modulation (with some pescadore QRM from 6925 kHz LSB).  Solid carrier on 6925.0 kHz.

OMs talking, yelling, seems to be clips from The Bounty...I recognize Anthony Hopkins' voice from the film.

S3-S4, solid signal with very little fading on the OH remote.  Much more readable here with wider AM audio.  9-10 kHz on peaks actually sounding pretty good.  

S3 with weak audio on the Milford, PA remote.  

1637 UTC - "I hope never to see Fletcher Christian again, unless it is to see him hanged"
1641 UTC - Ominous-sounding electronic music
1643 UTC - Men singing, ocean sounds in background
1646 UTC - Off suddenly, audio disappeared 1-2 seconds before the carrier dropped off

1460
OM and YL talking, piano music.  

S3 peaking to S5 via Ohio remote.

2043 UTC - Rap music

Seems like an episode of "The Boondocks"

1461
Live relay of 5150 on 6925 USB (on the Ohio remote)

S3-S4 signal at 1900 UTC
A bit of fading with Cum On Feel The Noise 1916 UTC
Van Halen - Panama 1919 UTC 

1462
Hearing electronic dance music strong on 6925 LSB (not AM or USB).  Liquid Radio is underneath but what I'm hearing right now is only on 6925 kHz LSB.  Possibly peskie party radio?  Haven't heard any lyrics yet.  

0112 - Rapid fade down to noise and then faded right back up
0113 - Track changes, nice driving house music with laser sound fx.  
0114 - OM (I think) vocals, but unable to tell what language/what's being said due to distortion

Via OH KiwiSDR and New Hampshire KiwiSDR.  

S5-S6 signal level on the Ohio remote
S3 signal level on the NH remote

Music and forest sound effects,

Man singing in the background.

2045: YL talking
2046: OM talking, battle sound effects in background
2048: YLs talking English/French, southern accented YLs
2100: Off (or extremely rapid drop in signal strength/fade)

1464
Appears to be a live relay of Electric Circus up on 6925 kHz USB.  Heavy fading and somewhat tinny audio leads me to believe its somebody using a remote receiver as their audio source.  

2117 UTC, heard a conversation between an OM and a YL underneath the Electric Circus relay.  Not sure if that's another station or simply lower-level audio on this transmitter's side.
2122 UTC - S3-S4 level carrier, with weak modulation
2125 UTC - YL heard talking underneath music, difficult to dig what is being said out of the (louder) music.
2129 UTC - Music (from Electric Circus on 6925 kHz USB) dropped off for a second, that or deep fade (or both).
2131 UTC - Signal now down to more of a S3 steady with some fades.  
2133 UTC - Sultry-sounding YL chatter now in the background...
2146 UTC - Relaying SSTV being sent by Electric Circus on 6925 kHz USB...

1465
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.

1809 UTC - Blue Christmas Without You
1945 UTC - Peanuts Christmas Theme

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:

1468
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.

1469
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

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.
