11 meters is starting to wake up
Shortwave Pirate Radio In North America And Around The World, And Other Signals That Go Bump In The Night
We seek to understand and document all radio transmissions, legal and otherwise, as part of the radio listening hobby. We do not encourage any radio operations contrary to regulations.
Always consult with the appropriate authorities if you have questions concerning what is permissible in your locale.
With good conditions it's a winner. I think 27.600 MHz FM and 27.650 MHz FM are easy enough to remember, plus there's already a group of guys using 26.805 MHz FM.
Another op I know here in Virginia heard a guy in Texas running FM on 27.285 MHz yesterday during the tail end of the band opening...that's right, FM on CB channel 28!
I agree these are pretty awesome. Hearing European and UK stations mixing in with Latin American and Caribbean stations and Russian hospital pager transmitters all at once is pretty amazing.

10/11 meters / 27.255 MHz - RadioShack On-Site Paging System Waveform (Waterfall) Test Video
« on: October 20, 2021, 1211 UTC »
https://www.youtube.com/watch?v=VrtAHDOtVII
It seems that the data transmissions heard on 27.255 MHz (and the other RC channels) during band openings are not from these paging systems...at least not the Radio Shack PG-99 17-6020 or 17-6023 (which is a 4-watt transmitter, and may work on 26.995 MHz instead of 27.255 MHz...not 100% sure there).
Thanks to Chris S. for providing the SDR and the test transmissions from the RadioShack 7 watt paging transmitter pager system (with stock back of set CB radio antenna).
Unlike the signals noted on 27.255 and 27.195 lately (27.195 only during band openings) - this system transmits a single FSK signal about 500 Hz from center frequency 27255.0 kHz. Center of the FSK signal is 27.2545 or 27254.5...usually there are two FSK signals - usually about -2.5 kHz or -3 kHz from center frequency and + 2.5 kHz or +3 kHz from center frequency.

« on: October 20, 2021, 1012 UTC »I would have never even thought about trying FM between 26 - 28 Mhz, had you not posted those freqs. I wouldn't say it's better than SSB, but hey it's something new and it works OR, ID and AZ on FM made me a believer. With good conditions anyway.

Now that FM mode is legal in the USA for CB purposes. Is FM CB legal in the USA? Yes, it is.
I fully support designating in-band and out-of-band calling channels. 26.805 FM and 27.600 FM. Legal CB Channels 27 FM, 29 FM, 30 FM and 31 FM. 27.600 MHz FM is right next to UK FM CB Channel 1 - 27.601 FM or 27.60125 MHz FM.

10/11 meters / Re: 11 meters is opening up again 1045 UTC 19 Oct 2021
« on: October 19, 2021, 1925 UTC »
I've noted FM on the following frequencies:
26.805 MHz FM - 26805 FM US stations - apparently this is the freeband FM calling frequency 26.805 FM (or the low channel FM calling frequency, similar to 26.915 MHz AM or 915 26.915 AM
27.125 MHz FM - 27125 FM CB Channel 14 - Spanish speaking stations...
27.255 MHz FM - 27.255 FM
27.600 MHz FM - 27600 FM - French speaking stations - not UK FM CB channel 1 (27.60125 MHz FM 27601.25 FM 27.601 FM)
27.650 MHz 27650 FM - Several different stations heard on this frequency - not UK FM CB channel 6 (27.65125 MHz FM 27651.25 FM 27.651 FM), these stations were definitely using 27.650 MHz
Interestingly enough, the UK FM 27/81 allocation is close enough to the "zeros" (27.600 MHz, 27.610 MHz, etc.) that the 1.25 kHz difference is usually not enough difference to make a difference.
Combine that with the fact that the Irish authorities allow use of the 40 UK FM channels (the Irish call UKFM 1-40 LW01-LW40) and 40 offset channels (27.605 MHz to 27.995 MHz in straight 10 kHz channel sequence - the 27.605-27.995 channels are referred to as UW01-UW40) and the regular 40 mid band CB (FCC CB) channels (simply called CB01-CB40) for Irish church radio broadcasts - Wireless Public Address System or WPAS...in Ireland FM and AM are allowed (yes, AM is allowed on the UK FM channel plan, the UW01-UW40 channels and the 40 CB channels for Church radio broadcasts.
So...for FM purposes, I think it's better to use the regular channels unless there's propagation to the UK.
Germany, Hungary, the Czech Republic and other places allow use of 80 CB channels - the standard 26.965-27.405 MHz 40 channel band plus 26.565 MHz to 26.955 MHz (26.565 MHz = channel 41, 26.575 MHz = channel 42, 26.585 = channel 43, 26.595 MHz = channel 44, up to 26.955 = channel 80). Channels 41-80 / 26.565 MHz to 26.955 MHz are FM mode only, channels 1-40 / 26.965 MHz to 27.405 MHz are AM/FM/SSB.
I fully support designating in-band and out-of-band calling channels. Seems like 26.805 MHz FM is the low channel FM calling channel. How about 27.600 MHz and an alternate that doesn't clash with the WPAS/CADS Irish Church radio/UK FM allocation for the high channel FM calling channel? 27.575 MHz FM sounds good to me.
As far as in-band goes...I don't think channel 14 - 27.125 MHz is a good call. Maybe channel 27 or 31 (I know that channel 31 FM is one of the standardized European FM calling channels...so it would make sense to make 31 FM the US FM channel.
So...
26.805 MHz - low channels FM calling channel
27.275 MHz - CB Channel 27 FM - USA FM CB calling channel
27.315 MHz - CB Channel 31 FM - USA FM CB calling channel
27.575 MHz - high channels FM calling channel
27.600 MHz - high channels FM calling/working channel (alternate)

« on: October 19, 2021, 1048 UTC »
Looks like we might be in for another busy day:
At 1045 UTC:
Hearing two English-speaking OMs on 26.885 MHz AM...heard a third station break in, request radio check...sounds like a local channel (where these guys are, I don't know...) but they've got decent modulation. Third station is considerably weaker...now a 4th station. IDs include Jaybird, Tomcat, and others. "I've got the preamp on and I still can't hear you as well..." "If I can hear you down here, I know they can hear you up there!" "We gonna talk to Possum" "Did you hear Ramblin' Man in The Carolina?"
This is almost certainly a local (regional) channel...
Weak signal noted at 1046 UTC on 26.875 MHz
1049 UTC I heard mention of "500 watts" on 26.885 MHz AM - and now they're working a station in Florida.
1050 UTC - "he's on one of them big fancy radios" (more English speaking stations) on 26.675 MHz AM
1140 UTC - 27.505 MHz AM and 27.605 MHz AM active
1142 UTC - guys on 27.605 MHz AM switched to FM mode (sounds like they're doing testing) - 27.605 FM...then the frequency went quiet - some weak SSB QRM in the background
1145 UTC - 26.885 MHz AM - US stations still very strong
1145 UTC - 26.675 MHz AM - US stations also good signals
1145 UTC - 26.805 MHz AM - US stations active
1147 UTC - 27.505 MHz AM - confirmed truckers on 27505 - "she got her own policy on the other truck" "primary driver" and other trucker-specific chatter
I checked the legal 40 channels locally with my handheld CB and almost all 40 channels were active. Channels 6, 11, 20, 21, 24, 25 and others were all quite active. Some sporadic signals coming in and out on channel 26 and 28. Heard some SSB activity on 38 and 39.

Hearing FM activity on 26.805 MHz 26805 FM at 1809 UTC...
The band seems to have calmed down a bit bit there are still a lot of signals in the 25.615 MHz to 26.955 MHz portion below channel 1. The regular 26.965 MHz to 27.405 MHz band is alive and the higher freqs are too...just not as crazy as before.
And...now 26805 is clear. I guess that's that? Maybe..

Taxi dispatchers all over the band..heard from 25.615 MHz AM (that's channel 1 on Band A for those people keeping score at home) up to 27.935 MHz AM - 27.935 AM is channel 7 on Band F!
Lots of taxis in the 25 MHz band (25.695 MHz, 25.775 MHz) the lower and mid parts of the 26 MHz band (26.005 MHz, 26.105 MHz, 26.175 MHz, 26.205 MHz, 26.365 MHz...) and the higher portion of 27 MHz...27.745 MHz, 27.765 MHz, 27.775 MHz, 27.835 MHz, 27.885 MHz...
28.015 MHz AM, 28.035 MHz AM, 28.065 MHz AM and 28.085 MHz AM also active with taxi dispatchers and Spanish speaking stations...operating in the 10 meter band no less!
Lots of Spanish language but a fair amount of French and Portuguese and some UNID languages heard. US based American Truckers on 27.685 MHz AM and a US STL signal on 25.950 MHz FM too. WWV coming in nicely on 25.000 MHz / 25000 kHz 25 MHz WWV.
The A/B bands 25.615-26.055 and 26.065-26.505 MHz (25.615-26.505 MHz - so lower than the "low channels" - Band C or 26.515 MHz to 26.955 MHz) filled with freebanders, truckers, taxi dispatcher and a surprising amount of SSB activity, including 25.985 MHz LSB and 26.540 MHz LSB in addition to usual suspects - 26.555 MHz LSB.
Inside the band lots of signals on top of each other. Noted FM voice, lots of AM voice (including a taxi dispatcher) and several different FSK signals on 27.255 MHz - CB Channel 23. Also French language on 27.255 USB.
FSK signals heard on 27.195 MHz almost constantly. Taxi dispatchers on all the R/C channels all over the band today.
Lots of taxis in the 25 MHz band (25.695 MHz, 25.775 MHz) the lower and mid parts of the 26 MHz band (26.005 MHz, 26.105 MHz, 26.175 MHz, 26.205 MHz, 26.365 MHz...) and the higher portion of 27 MHz...27.745 MHz, 27.765 MHz, 27.775 MHz, 27.835 MHz, 27.885 MHz...

1414 UTC - 27.255 MHz super messy, hearing FSK mixing in with all sorts of AM traffic, lots of noise toys, roger beeps, etc.
1416 UTC - 26.995 MHz AM with taxi cab dispatch (roger beep end of transmission of course)
1417 UTC - 27.255 MHz AM - YL taxi dispatcher on top of the pileup !!

10/11 meters / 26805 FM 26.805 MHz FM - US FM Calling Channel FM 11m Freeband Channel
« on: October 18, 2021, 1152 UTC »
Good morning,
I stumbled upon a Facebook page dedicated to promoting the use of 26.805 MHz FM as a FM calling/working channel, much like 26.915 MHz (and nearby frequencies like 26.885, 26.955, etc) are used for AM calling/working on the lower channel side.
This matches up with the station I heard transmitting the audio recording loop yesterday "Big Grandpa...this is Big Grandpa calling...Las Vegas!" on 26.805 MHz FM 26805 kHz FM 26805 FM. It was clearly a loop or maybe a voice keyer set up...but the guy was transmitting FM!
Yet another frequency to keep an eye out for/ear out for. They actually picked a pretty good frequency too. 26.815 and 26.835 are sometimes really busy...but 26.805 not so much.
Maybe we will see more FM usage within the CB band as well as outside the FM band as time goes on.

This is interesting - and matches with the Big Grandpa Las Vegas station heard on 26805 FM 26.805 MHz FM 26.805 FM heard yesterday...apparently there's a FM group and 26.805 MHz is their "home" channel or FM calling channel.

We've been literally waiting years for conditions to be this good again
I agree these are pretty awesome. Hearing European and UK stations mixing in with Latin American and Caribbean stations and Russian hospital pager transmitters all at once is pretty amazing.

Now, a hair after 2215 UTC, I'm still hearing a YL taxi cab dispatcher on 25.695 MHz AM, the same user heard in numerous other logs and earlier today.
26.415 MHz AM, 26.585 MHz AM, 26.605 MHz AM and several other frequencies below CB channel 1 are also active. 26.645 MHz AM coming in nicely from Puerto Rico at 2218 UTC. CB channel 5 - 27.015 MHz AM is still very busy too.
At 2217 UTC, the YL taxi dispatcher on 25.695 AM is a solid SIO 444.
At 2219 UTC, noted several FSK data bursts on 27.095 MHz, followed by a YL reading numbers (in AM mode - likely another taxi cab company using 27 MHz - this time, using 27.095 MHz R/C channel.
2222 UTC - several FSK bursts (sound like the data links usually heard on 27.255 MHz) on 27.195 MHz (weak, but the sound is identical). No voice signals mixing in with the data bursts...
