These guys love using the "low channels" (frequencies below CB channel 1).  The "low band" or "band C" seems to be where they hang out the most (26.515 MHz to 26.955 MHz). 

26.555 MHz LSB - Latin America SSB DX calling frequency (see also: 27.455 MHz USB) - stations will QSY from 26.555 LSB onto 26.545 MHz LSB, 26.565 MHz LSB, 26.525 MHz LSB, 26.540 MHz LSB, 26.570 MHz LSB and others.

26.515 MHz AM - I've heard taxi cab companies, US stations and lots of Latin American chatter on here
26.525 MHz AM - alternate AM frequency, also used for SSB freebanders (in LSB mode)
26.535 MHz AM - alternate AM frequency, taxi cab dispatcher (in AM mode) and SSB freebanders (in LSB mode)
26.545 MHz AM - mostly used for SSB activity (in LSB mode), but I've heard AM signals on here too
26.555 MHz LSB - Yep, very busy
26.565 MHz AM - alternate frequency
26.575 MHz AM - alternate frequency
26.585 MHz AM - big radios, big power - Mexican trucker and freebander frequency
26.595 MHz AM - alternate frequency when 26.585MHz AM is just going nuts (as it often is)
26.605 MHz AM - very popular
26.615 MHz AM
26.625 MHz AM
26.635 MHz AM - very popular with Mexican freeband CB operators and others
26.645 MHz AM
26.655 MHz AM - another popular frequency
26.665 MHz AM - I've noticed Spanish language chatter on here a lot more lately
26.675 MHz AM - US stations, Spanish language also noted
26.685 MHz AM - Spanish language, also taxi cab dispatcher YLs, also US truck drivers (identified as ABF (trucking company) use?)
26.695 MHz AM - Mexican accented Spanish, also big radios out of Florida, Puerto Rico and Caribbean area
26.705 MHz AM - BIG radios out of Puerto Rico and other areas (see also: 26.695 AM, 26.715 AM, 26.725 AM)
26.715 MHz AM - BIG radios (similar to 26.705 AM)
26.725 MHz AM - alternate to 26.705 MHz AM and 26.715 MHz AM
26.735 MHz AM - Lots of truck drivers on here, but also Latin American traffic
26.745 MHz AM - taxi cab dispatch YL (Spanish language) heard here
26.755 MHz AM - Spanish language and English speaking freebanders
26.765 MHz AM - Mexican taxi cab dispatcher, female YL dispatch lady, very strong signal at points
26.775 MHz AM - I've heard a lot of stations out of the southern USA on this frequency
26.785 MHz AM
26.795 MHz AM
26.805 MHz AM - Spanish language stations, note: this is unofficially now a FM frequency 26.805FM
26.805 MHz FM - US freeband CB operators, FM mode, very popular 26.805 FM or 805 FM club
26.815 MHz AM - US stations, mostly
26.825 MHz AM
26.835 MHz AM
26.845 MHz AM
26.855 MHz AM
26.865 MHz AM
26.875 MHz AM
26.885 MHz AM - US stations, including those that QSY'ed from 26.915 AM, etc
26.895 MHz AM
26.905 MHz AM - Known taxi dispatcher frequency, also US freebanders QSYed from 26.915 AM
26.915 MHz AM - BIG radios, commonly called "36 low" or "915"
26.925 MHz AM - Lots of different users on here
26.935 MHz AM - I've heard lots of Spanish here, also taxi dispatcher lady
26.945 MHz AM - US stations, running power, and Spanish speaking taxi cab dispatch comms
26.955 MHz AM - Taxi dispatcher (Spanish), and also lots of US freebanders

The lower channels, that is, Band A (25.615 MHz - 26.055 MHz) and Band B (26.065 MHz to 26.505 MHz) so overall

25.615 MHz up to 26.505 MHz is very popular with

Freeband SSB operators, usually clustered around 26.285 MHz USB, 26.225 MHz USB and a handful of others

Taxi cab companies (all over!)
Truckers (mostly on 25.835 MHz AM but heard all over)
Hunters, hunt club channels
Forestry, farmers, etc.  using a "clear channel"


From what I've read, many CB users in Latin America are either using:

Export radios (aka "10 meter" radios) which cover:

25.615 MHz to 30.105 MHz - the new "standard" - Chinese rigs
26.515 MHz to 27.855 MHz - "120 channel" CB rigs, usually with a "LOW/MID/HIGH" band switch (CB band is "MID")
25.615 MHz to 27.405 MHz - Hunting radios, with A-B-C-D band switch (CB band is "Band D")
26.065 MHz to 27.405 MHz - Hunting radios, with B-C-D band switch (CB band is "Band D"
25.615 MHz to 28.305 MHz - the 6-band "240 channel" A-B-C-D-E-F band standard plan (CB Band is "Band D")
25.165 MHz to 28.755 MHz - the 8-band "320 channel" band plan
24.265 MHz to 29.655 MHz - Superstar 158EDX and several other radios

Or, modified CB rigs that have had frequency expansion modifications done on them,

80 channel modification:

26.515 MHz to 27.405 MHz - channels 1-40 are the same as regular CB channels 1-40, channels 41-80 are the "low channels"
26.515 MHz to 27.855 MHz - very popular "120 channel" mod or "expansion" modification, gives the user three sets of 40 channels -  low channels (26.515 - 26.955 MHz), mid channels/CB channels (26.965 - 27.405 MHz, the standard CB band), and high channels (27.415 - 27.855 MHz).  Most of these radios also include the addition of a +10 kHz switch or a "+10kc" switch, allowing the user to access the skipped channels, LesComm, Viagra, Expo 100 and numerous other kits include kits to turn a regular 40 channel CB into a 120 channel CB. 

Other kits include the addition of the "B Band" (26.065 MHz - 26.505 MHz) for a total of 120 channels, or even more coverage (for example, 25.995 MHz to 28.045 MHz, 26.005 MHz to 27.995 MHz, 26.695 MHz to 27.965 MHz, etc.

10/11 meters / 11m Band Activity 30 DEC 2022
« on: December 30, 2022, 1311 UTC »
Checking the eastern and central European SDRs this morning, along with East Coast USA SDRs, looks like Latin American chatter is already starting to pop up on the usual in-band channels.

On Polish and German SDRs, noting POCSAG pager activity on 26.500 MHz, 26.550 MHz, 26.600 MHz, 26.650 MHz, 26.695 MHz, 26.700 MHz, 26.745 MHz, 26.750 MHz, 26.800 MHz, 26.900 MHz, 26.940 MHz, 26.945 MHz, 26.950 MHz, 26.955 MHz, 27.300 MHz, 27.350 MHz, 27.450 MHz and 27.845 MHz and offset frequency 27.847 MHz / 27.848 MHz as well as 27.850 MHz.

10/11 meters / 11m Band Activity 29 DEC 2022
« on: December 29, 2022, 1325 UTC »
Noting some FM voice on 27275 (CB Channel 27) and 27295 (CB Channel 29).

Also the usual Latin American frequencies are starting to light up, including


26525 LSB 26.525 MHz LSB - alternate frequency (likely stations that QSY'ed from 26.555 LSB)
26555 LSB 26.555 MHz LSB - SSB calling (low channels)
26585 AM 26.585 MHz AM - Mexico
27065 AM 27.065 MHz AM - Very big signals (CB Channel 9)
27455 USB 27.455 MHz USB - SSB calling (high channels)

Some very faint POCSAG paging signals noted on 26.695 MHz. 

The usual FSK bursts on 27.255 MHz RCRS channel / CB Channel 23

Nothing on 27.195 (yet) but I imagine the MFSK multi-frequency data signal will show up there as well.

10/11 meters / Re: 11m Band Activity observation 21 Dec 2022
« on: December 27, 2022, 1250 UTC »
1900 UTC, 27.383 mhz lsb. A group of knuckleheads deciding to create their own channel 2khz under .385. Creates the usual qrm wars that one might assume. The group blows off anyone complaining, of course. ;-)

That's always fun.  They're on what, 27.383 MHz LSB? 

Would make more sense to use 27.380 MHz or 27.390 MHz.  During the peak of the last sunspot cycle, I regularly heard stations on 27.360 LSB, 27.370 LSB, 27.380 LSB, 27.390 LSB and 27.400 LSB (in addition to the usual 27.385 LSB and other nearby legal channels).  2 kHz isn't enough.  Sounds like they did it more to create chaos on 38LSB vs. actually to have a clear frequency.  If they can all move down to 27383 LSB, they can almost certainly move down to 27380 LSB (or up to 27390 LSB). 

Whatever happened to folks just switching to the other sideband?  Every radio that has LSB mode also has USB mode.

1830 UTC

Latin American stations coming in nicely now, especially in the legal 40 CB channels.

Lots of US stations as well.  Noted some odd data bursts on 27.195 MHz (not the usual MFSK signal that comes in when the band is open to Latin America).  Lots of data on 27.255 MHz.  Signals on all 40 of the legal channels.

10/11 meters / Re: 11m Band Activity 0942 21 DEC 2022
« on: December 21, 2022, 1148 UTC »

Still early here on the US East Coast (0645 local time, 1145 UTC).

Noting FSK data bursts on 27.255 MHz (not local) - on my local receivers.  The usual suspects (27025 AM, 27065 AM, 27085 AM, 27185 AM, 27265 AM, 27285 AM, 27385 LSB, etc.) are waking up.

10/11 meters / Re: 11m Band Activity 20 DEC 2022
« on: December 20, 2022, 1603 UTC »
Now (1600 UTC),

The UK paging frequencies (26.695 MHz, 26.745 MHz, and a couple others) are still coming in, but not nearly as strongly as before.  Noting more data signals on the legal data/RC "Class C" (Part 95C of the FCC rules) frequencies 26995, 27045, 27095, 27145 and especially 27195 and 27255.  Some FM voice on 27275 and 27125, but mostly AM.

Latin American DX now coming in nicely, taxi dispatcher on 26.765 AM is very loud, hearing more Spanish language chatter across the band, including on 26.935 AM and 26.945 AM.  Taxi dispatcher on 26.905 MHz AM mixing in with other stations. 

I stand corrected:  UK FM signals still coming in on

27781 FM - UK FM CB Channel 19 - 27.781.25 MHz FM
27871 FM - UK FM CB Channel 28 - 27.871.25 MHz FM
27891 FM - UK FM CB Channel 30 - 27.891.25 MHz FM
27941 FM - UK FM CB Channel 35 - 27.941.25 MHz FM
27961 FM - UK FM CB Channel 37 - 27.961.25 MHz FM
27971 FM - UK FM CB Channel 38 - 27.971.25 MHz FM

Also a fair amount of SSB activity within the 27.6 MHz to 28.0 MHz portion (which is where the UK FM 27/81 band is), including on 27845 LSB, 27855 USB and several others.  Taxi cab dispatchers active there as well as the usual Spanish and Portuguese language SSB

249
As a follow up to this - the band is open again today, and I'm hearing faint POCSAG signals on 31.7250, 31.7500 and 31.7750...fading up out of the noise a tiny bit right now (1530 UTC) on 20 December 2022.

The 11m band is wide open the Europe, the UK and Latin America right now so it makes sense. 

250

Awesome logs - and reference frequencies.  It's pretty cool how much use they make of the 54-88 MHz frequencies, especially the 60 MHz and 70 MHz region, which I imagine is pretty darn clear now.

Also, that antenna is kickass.  30-88 MHz.  Love it.  Reminds me of a discone design. 

There seems to be a lot more usage of 30-88 MHz (or even just 30-50 MHz) than you'd think.  I often read the RadioReference.com forums (there's a nice long VHF low band logs thread, one per year, keeps things nice and searchable) and there is a lot of VHF low band military activity, especially in the lower portions (below 35 MHz or 40 MHz or so..although the 40-42 MHz band is the biggest chunk of military/government frequency allocation within the 30-50 MHz low band).  Lots of 30 MHz, 31 MHz, 32 MHz, 34 MHz and random frequencies that are within the land mobile bands.

10/11 meters / Re: 11m Band Activity 19 DEC 2022
« on: December 19, 2022, 1514 UTC »
Sounds like another excellent opening.

I heard a fair amount of UK FM CB chatter (especially on channels 6, 19, 38, 39 and 40 - so 27.651 FM, 27.781 FM, 27.981 FM and 27.991 FM).  Noted POCSAG activity on 27.450 MHz, 27.650 MHz, 27.700 MHz, 27.750 MHz and multiple data/pager signals around 27.85 MHz (offset frequency, 27.846 MHz or 27.847 MHz). 

The usual UK 26 MHz band paging frequencies were also alive - 26.695 MHz, 26.700 MHz, 26.705 MHz, 26.745 MHz, 26.750 MHz MHz, 26.755 MHz...with Spanish language taxi dispatchers mixing in (26.765 MHz AM had a very good signal over the weekend, YL taxi dispatcher).  Taxis active on 27.785 AM while UK FM came in on 27.781.25 FM.  European pagers booming in on 26.800 MHz, 26.850 MHz, 26.900 MHz, 26.950 MHz and 27.300 MHz.  UNID data signals on 26.940 MHz, 26.945 MHz, 26.950 MHz, 26.955 MHz, 26.960 MHz...

UK hospital paging active on 31.725 MHz, 31.750 MHz and 31.775 MHz as well.  Strangely, the 29 MHz frequencies seemed quiet.   27.975 AM with Spanish language OM chatter.   Fair amount of AM signals in the lower portions of 10 meters (CBers in 10 meters), namely 28.005 AM, 28.035 AM, 28.055 and many other frequencies, up to 28.235 MHz.

Lots of interesting UNID signals in this band, CB is not dead!

An interesting note regarding French language chatter, I've noticed that French chatter seems to pop up in the upper reaches of the 25.615 MHz to 30.105 MHz coverage of most export rigs, especially in the 27.9 MHz to 28.0 MHz region, including 27.995 MHz USB, 27.997 MHz LSB, and 29 MHz band frequencies, namely 29.775 MHz AM, 29.815 MHz AM, 29.825 MHz AM, 29.875 MHz AM, 29.905 MHz AM, 29.915 MHz AM, 29.925 MHz AM and 29.975 MHz AM.  The 29 MHz AM signals all sounded like freeband CBers - but the language was only French. That, or its a land mobile user (legit, licensed user).  Probably not though, considering use of AM mode.  Another interesting indicator are the 29 MHz pagers - 29.750 MHz, 29.800 MHz, 29.850 MHz, 29.900 MHz, 29.950 MHz.  Canadian hospitals are still found on 30.020 MHz (and others).

« on: December 16, 2022, 1857 UTC »
It's been going nuts.

I'm currently listening to what sound like truck drivers (Spanish speaking) on 28005 AM. 

I'm sure these land mobile users are operating in 10 meters all the time, but now they're actually coming through.  Lots of taxi cab comms on 25 MHz, 26 MHz and 27 MHz as the propagation shifts from the UK and Europe to Latin America

Recent logs:

28.235 MHz AM - taxi dispatcher (Spanish language)
28.205 MHz AM - taxi dispatcher (Spanish language)
28.085 MHz AM - truckers - English language
28.055 MHz AM - taxi dispatcher (Spanish language)
28.035 MHz AM - taxi dispatcher (Spanish language)
28.025 MHz AM - taxi dispatcher (Spanish language)
28.005 MHz AM - multiple stations at once, hearing OMs and a YL taxi dispatcher


Some other oddities:

27.975 MHz AM - group of US truck drivers using export radios, most of which are in serious need of an alignment - carrier frequencies noted below:

27.974.1 MHz
27.976.0 MHz
27.977.9 MHz
27.975.3 MHz
27.975.8 MHz



27.385 MHz LSB - as to be expected, then somebody playing music (in FM mode) on top of the SSB traffic - CB Channel 38
27.255 MHz dozens of different data signals, with AM and FM voice (mostly AM) mixing in
27.207 MHz - Another odd FSK signal, center frequency might be closer to 27.208 MHz
27.205 MHz FM - Lots of FM signals on top of each other - CB Channel 20
27.205 MHz AM - AM and FM and SSB, the area around 27.2 MHz / CB Channel 20 is really messy
27.201 MHz USB - Spanish language, very good signals
27.198 MHz USB - center frequency 27.199 MHz - narrow band FSK data signal, 2.5 kHz wide
27.195 MHz MFSK - constant multiple-carrier frequency shift keying data signal, about 6.5 kHz wide
27.195 MHz MFSK - the constant signal faded away, now a rapid burst signal is on the frequency (with AM voice traffic)
27.195 MHz AM - taxi dispatch lady (Spanish language)
27.195 MHz AM - "Can you copy the radio?" (English, very good signal)
27.095 MHz - Yet another unique data signal, bursts every few seconds, FSK, about 5 kHz wide
27.095 MHz AM - another taxi dispatcher - YL speaking Spanish
27.000 MHz USB - Weak voice traffic noted
26.995 MHz MFSK - Very similar signal to the one noted on 27.195.  The 27.195 MHz MFSK data signal is a good indicator of the band being open to Latin America
26.995 MHz AM - Hearing OMs talking, does not sound like a taxi or other business or land mobile user
26.995 MHz AM carrier, 26994.5 kHz zero beat

kris,

Thank you very much for the insight regarding these operators.   I figured they were either outbanders (bootleggers, freebanders) and/or were guys using old AM mode marine or military equipment with analog frequency displays in the 2-3 MHz region. 

It makes sense given that a large number of World War II transmitters or combined transmitter-receiver sets operated in that (roughly) 2-4 MHz range (lots of equipment only covered the higher bands, like 3.8 MHz to 6.5 MHz or so).  The older-generation marine radiotelephone equipment also worked in that similar range (1.6 to 4 MHz or 2-4 MHz), with some transitional-generation gear having the capability to run in "AM equivalent" or "AME" mode (SSB with a carrier so an AM only receiver could demodulate their signal, but somebody with their radio set to USB mode could also talk to them). 

These transmissions are very easily heard using internet SDR receivers located in Poland and other locations in Europe, but, understandably so, they are very strong on receivers in Poland, Ukraine and Russia (this was pre February 2022 in the case of the Russian and Ukrainian KiwiSDRs). 

100 meter band.  I like the sound of that.  100m is 3 MHz or 3000 kHz.
