Hello all,

This is an interesting one, now that I’ve managed to catch the voice transmissions as well as the paging data. 

The voice messages include a “tone out” (possibly a selective calling tone) burst prior to the voice message.  Frequency is 27.885 MHz. 

The recordings linked below were all made via an online SDR in the UK, specifically the G8JNJ SDRs:

27.885 MHz FM Alert Tones Voice Message + Paging Signals [Part 1] G8JNJ SDR - 27 Feb 2024
https://youtu.be/FlRQfJUgLBI

and

27.885 MHz FM Alert Tones Voice Message + Paging Signals [Part 2] G8JNJ SDR - 27 Feb 2024
https://youtu.be/VUbcwUtgOiA


Voice message for “Part 2” begins at the very beginning of the video. 

For “Part 1” there is an in-progress voice message when I start recording.  At 0:28 in, you can hear the “tone out” burst - one long tone followed by two short tones…followed immediately by a voice message.   


Numerous other videos of the paging signals - including the various bandwidth POCSAG signals on frequency have been captured and are on the regular “R4002” page. 


The links above are the best capture I’ve gotten of the voice messages though. Here are the other two videos of the voice message:

27.885 MHz FM Data Paging + FM Voice Transmission UNID Source [G8JNJ SDR] 23 Feb 2024 [Part 1]
https://youtu.be/bFesHLxAHvc

^ voice transmission in progress at the very beginning of the recording.  This one is the worst quality of the clips I managed to get.  There is a “Part 2” video from 02/23/2024 but it only shows data / paging signals and increasing QRM from freeband CB radio signals on 27.880 MHz USB, 27.885 MHz LSB and 27.885 MHz AM - U.S. out of band 11 meter CB signals starting to fade in.

Older video / audio recordings of the voice paging pager / POCSAG paging on 27885 FM:

https://youtu.be/C6R50M8Q-dY

^ from December 15th, 2023.  Tone out / alert tone at 0:16 in, follows the same format - one long tone burst followed by two short tone bursts followed by a voice message transmission (FM mode) followed by a moment of unmodulated FM carrier…then it switches back to paging data bursts.

10/11 meters / UK FM CB Activity 1945 UTC 26 Feb 2024
« on: February 26, 2024, 2027 UTC »
The band is lighting up this afternoon.  Lots of activity on UK FM CB radio channel 19, plus numerous others:

27.601 FM 27.60125 MHz FM - UK FM CB Channel 1 - FM carriers and voice, lots of SSB QRM - possibly music carriers?
27.631 FM 27.63125 MHz FM - UK FM CB Channel 4 - unmodulated FM carrier (???), QRM from 27.635 MHz
27.681 FM 27.70125 MHz FM - UK FM CB Channel 9 - another carrier - tons of QRM
27.731 FM 27.73125 MHz FM - UK FM CB Channel 14
27.751 FM 27.75125 MHz FM - UK FM CB Channel 16
27.781 FM 27.78125 MHz FM - UK FM CB Channel 19
27.791 FM 27.79125 MHz FM - UK FM CB Channel 20
27.831 FM 27.83125 MHz FM - UK FM CB Channel 24 - busy, QRM from AM freeband CB signals on 27.835 MHz
27.841 FM 27.84125 MHz FM - UK FM CB Channel 25 with QRM from 27.845 MHz AM taxi cab dispatch
27.861 FM 27.86125 MHz FM - UK FM CB Channel 27
27.901 FM 27.90125 MHz FM - UK FM CB Channel 31
27.911 FM 27.91125 MHz FM - UK FM CB Channel 32
27.921 FM 27.92125 MHz FM - UK FM CB Channel 33 with QRM from 27.915 MHz AM and 27.925 MHz AM truck drivers
27.931 FM 27.93125 MHz FM - UK FM CB Channel 34
27.951 FM 27.95125 MHz FM - UK FM CB Channel 36
27.961 FM 27.96125 MHz FM - UK FM CB Channel 37
27.971 FM 27.97125 MHz FM - UK FM CB Channel 38 - calling frequency
27.981 FM 27.98125 MHz FM - UK FM CB Channel 39
27.991 FM 27.99125 MHz FM - UK FM CB Channel 40

27.841 FM (UK FM CB Channel 25) is actually as busy as 27.781 FM.  Unfortunately there's enough Latin American taxi cab comms starting to come in that the AM mode land mobile comms QRM is becoming a thing, especially on 27.78125MHz

Plenty of in-band activity and SSB all over the place.  26.805 MHz FM active as well.   

UK paging pager signals POCSAG on 26.745 MHz, 26.705 MHz, 26.695 MHz, 26.350 MHz, 26.250 MHz and 26.200 MHz.

10/11 meters / Class C CB (RCRS) 27 MHz Telemetry Yahoo Group Archive
« on: February 26, 2024, 1816 UTC »
Info from the VHFDX email chain, good group of 25-30 MHz and VHF low band DXers (as well as other bands, including 22m interest).  Given the amount of data traffic on 27.255 MHz and the other RCRS frequencies, I wanted to share this with the HFU forums so this link is archived

Received via the W3HFU SDR and locally (local receive setup consisting of a PNI Escort HP 82 handheld AM / FM CB walkie talkie with a HYS 51” telescoping whip. 

Recording transmitted at least twice.  Included English translation of German, plus crowd noise.  Waterfall waveform shows no delay in the two signals…but the 26.855 MHz FM signal had more FM deviation. 


26805 FM 26,805 kHz 26805 MHz
26855 FM 26,855 kHz 26855 MHz

Recording of the signals as received via SDR:

[Part 2]
https://youtu.be/_D0d_wHaJdA

The first SDR clip also shows a strong AM signal on 26.825 MHz, unrelated to the simulcast on 26.805 FM and 26.855 FM. 

And received locally on the handheld CB

[Part 2]
https://youtu.be/3XCGizYum3c


The PNI HP82 is in DE mode 80 channel CB radio mode, so 26.805 MHz FM is channel 65 and 26.855 MHz FM is channel 70. 


The 26.855MHz signal sounds a bit distorted, likely due to the higher level of FM deviation on that signal. 

The band was open to Europe and the UK as well as the Americas - signals from the U.S. and Latin America were booming in all at once, with lots of FM mode CB radio signals mixing in with domestic AM and SSB, including French and German CB radio traffic on channels 38 and 39, often completely blocking LSB signals on 27.385 MHz and 27.395 MHz. 

FM CB radio activity coming in on the known DX calling channels frequencies 27.305 MHz and 27.315 MHz / CB Channel 30 FM and 31 FM.  American FM CB activity on 27.275 MHz FM (CB Channel 27 FM) and 27.295 MHz FM (CB Channel 29 FM) plus 30 and 31, with lots of severe QRM at points.  Channels 35-40 had AM, FM and SSB going all at once. 

Lots of German language signals on 26MHz band German FM CB channels and the UK FM channels were busy too.  27.78125 MHz FM was very busy, as to be expected.  Lots of Latin American language taxi dispatch chatter, including the 27.785 MHz AM Mexican taxi cab dispatch LMR comms, plus American free band CB signals, lots of SSB but also AM, including 27.845 MHz AM, 27.855 MHz AM, 27.865 MHz AM, 27.905 MHz AM, 27.915 MHz AM, 27.925 MHz - possible militia comms on 27.925MHz AM with QRM from 27.92125 MHz FM and 27.93125 MHz FM

Hearing locally on my Tecsun portable and via several online receivers on the East Coast of the USA. 

Strong signal on the W3HFU receivers.  Solid SIO 555.  Signal strength a solid S7...peaking up to S8 and S9 at points.  Strong AM modulation, almost exactly 10 kHz wide on 25900 kHz 25.9 MHz

AKKORD data link 9.6 kbps 9600bps targeting information for air defense (coming in basically daily at this point).  Via the G8JNJ SDR, tune in time 1344 UTC, writing this at 1345 UTC. 

Frequency 33.4 MHz
Bandwidth approx. 25-30 kHz
FSK variable speed air defense system data link.  Radar site tactical datalink to command center (control center) for possible

S-300 air defense system (NATO reporting name: SA-10 Grumble)
S-400 air defense system (NATO reporting name: SA-21 Growler)

Noting similar data stream signal on 33.500 MHz at the same time, as well as the usual Asian fishermen yakking away Asian fishery radio chatter on:

29.8250 MHz FM
29.8750 MHz FM
29.9625 MHz FM
29.9750 MHz FM
30.1250 MHz FM
33.1000 MHz FM
33.4375 MHz FM
33.5625 MHz FM - with US LMR fire rescue dispatch on 33.560 MHz FM

1335 UTC tune in via the G8JNJ SDR.    Narrow FM, 6-7 kHz bandwidth so the nearby POCSAG paging signals and other LMR taxi cab radio taxi dispatch signals aren't too much of an issue.
