Lots of Mexican taxi cabs and other freeband 11 meter comms in the past couple days. Yesterday the band was open nicely to Europe as well, with the German 80 channel CB allocation coming in (channels 1-40 are the same as the U.S. and European standard band plan, with AM, FM and SSB allowed, channels 41-80 are 26.565 MHz to 26.955 MHz in sequential order, 10 kHz spacing, with only FM voice or data allowed). Activity noted on 26.805 MHz FM including U.S. stations. Also plenty of UK FM CB activity, with a good amount of QRM examples (eg. taxi cab dispatcher on 27.785 MHz AM and UK FM CB channel 19 on 27.78125 MHz FM causing tons of QRM to each other).
Like Germany (and the other countries that use the 80 channel German band plan), the UK also has 80 legal CB channels - the regular "mid band" CB band (identical to our band plan) + 40 UK only channels (often called "27/81"). The UK FM channels are FM mode only, sequential channel numbering with 10 kHz steps, no skipped channels or out of sequence numbering, using the oddball 1.25 kHz offset channel plan:
27.60125 MHz FM - UK FM CB Channel 01
27.61125 MHz FM - UK FM CB Channel 02
27.62125 MHz FM - UK FM CB Channel 03
27.63125 MHz FM - UK FM CB Channel 04
27.64125 MHz FM - UK FM CB Channel 05
27.65125 MHz FM - UK FM CB Channel 06
...
up to
27.78125 MHz FM - UK FM CB Channel 19
27.79125 MHz FM - UK FM CB Channel 20
27.80125 MHz FM - UK FM CB Channel 21
27.81125 MHz FM - UK FM CB Channel 22
27.82125 MHz FM - UK FM CB Channel 23
...
27.97125 MHz FM - UK FM CB Channel 38
27.98125 MHz FM - UK FM CB Channel 39
27.99125 MHz FM - UK FM CB Channel 40
Just like Germany (and most of Europe) and the U.S.A. - AM, FM and SSB are allowed on the "mid band" 26.965 MHz - 27.405 MHz CB band, but only FM is allowed on the UK only band. Much like the German "extra channels" where FM is only allowed, use of CTCSS and DCS is becoming more widespread on the UK FM channels as more radios enter the market with CTCSS and DCS capability "out of the box".
UK FM Channel 19 - 27.78125 MHz (27.781 MHz works just fine too) is often the starting point. Channel 14 (27.73125 MHz FM) is the "home base" channel, and use of the other channels is somewhat regional in terms of the "gentleman's agreements", but farmers and other land mobile users make extensive use of the UK FM CB service (often with CTCSS).
Our friend on 26.765 MHz AM was coming in loud and clear on Thursday 09/18/2025 and yesterday 09/19/2025. Yesterday she had some QRM from German speaking CB signals (in FM mode) on the same frequency (26.765 MHz FM is German 80 channel CB channel 61).
Things get really crazy when the DX is really rolling in and the Mexicans on 26.585 MHz AM are getting clobbered by German and Czech language comms in FM mode on the same frequency.
Further adding to the fun is the fact that many European countries still use the 26 MHz and 27 MHz bands extensively for paging and datalinks. 26.605 MHz, 26.645 MHz, 26.655 MHz, 26.745 MHz, 26.785 MHz, 26.815 MHz and 26.835 MHz are big out of the UK in terms of paging systems. 26.200, 26.250, 26.300, 26.350, 26.400, 26.450, 26.500, 26.550, 26.600, 26.650, 26.700, 26.750 and especially 26.900 MHz are used by several countries in the EU for similiar purposes. Same with 26.950 MHz, 27.450 MHz, 27.500 MHz and numerous others, including frequencies that clash with the UK FM band 27.60125 MHz - 27.99125 MHz (UK regs call it 27.59625 MHz to 27.99625 MHz).
That, and the Irish allocation for church radio (parish radio) broadcasts mirrors the UK FM band plan (but allows use of AM in addition to FM), includes an offset channel plan (27.605 MHz - 27.995 MHz in 10 kHz steps, both AM and FM allowed) and allows use of the regular 40 CB channels for the same purposes.
I also heard a good amount of U.S. truck drivers, maybe logging companies or similar users on 25.835 MHz AM, 26.055 MHz AM, 26.285 MHz AM, 26.625 MHz AM, 26.735 MHz AM, 26.755 MHz AM, 26.825 MHz AM, 26.835 MHz AM, 26.885 MHz AM, 27.415 MHz AM, 27.535 MHz AM, 27.575 MHz AM, 27.585 MHz AM, 27.635 MHz AM, 27.855 MHz AM, 27.905 MHz AM and 27.915 MHz AM.
