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

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:

^ 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.

Follow up, I believe I have compiled all my recordings of the voice pager (with tone out alert tones) + narrowband POCSAG + wideband POCSAG paging system on 27.885 MHz 27885 kHz:
