11m Pager Data and other activity 1600+ UTC 9 February 2022
« on: February 09, 2022, 1634 UTC »
Noting FSK signals on numerous frequencies in the 26 MHz region, as well as:

26569 FM - Narrow FSK bursts
26610 FM - 26.610 MHz or 26.609 MHz, very strong FSK signal
26635 FM - POCSAG
26695 FM - POCSAG
26705 FM - FSK signal
26710 FM - Narrow FSK bursts
26730 FM - Narrow FSK bursts
26745 FM - Nice paging signal faded in
27195 FM - Very strong data signal - seemed like an AM-modulated series of tones


Also, lots and lots of Spanish language taxi dispatch ladies, including 25.695 MHz, 26.935 MHz, 27.365 MHz (CB channel 36, in-band, nice!), 27.745 MHz and our friends in Mexico City on 27.815 MHz / 27815 AM

At 1630 UTC, some data mixing in with AM voice - another taxi cab dispatcher YL operator reading numbers (taxi IDs) on CB channel 23 - 27.255 MHz / RC Channel.

27755 AM - Taxi dispatcher
27935 FM - French language (yes, in FM mode, and not on UK FM CB CH 34 27.931.25 FM, they're on 27.935 MHz!)

27255 AM - a different taxi dispatcher, multi-tone roger beep, mixing with some (weak) FSK
26.745 MHz at 1638 UTC, the signal is still there, roughly 6 kHz wide, you can tune it on either 26745 USB or 26745 LSB (like many of the paging signals coming out of Europe).  At the same time, the paging or data signal on 26.695 is getting stronger....then both 26695 and 26745 faded almost completely out for a few moments and then came back in.

26665 USB - somebody doing radio tests, whistling
26695 fading in and out
26800 FM - narrow FSK signal
26837.5 or 26838 - narrow FSK signal, would probably tune on 26.840 MHz LSB
27705 AM - Taxi dispatcher
27725 AM - Taxi dispatcher
27775 AM - Taxi dispatcher
27785 AM - Taxi dispatcher
26859 or 26860 - narrow FSK signal, center frequency is just a bit below 26.860 MHz
27900 USB - very strong QSO in Spanish, two OMs having casual QSO, 27.900 MHz USB 27.9 MHz 27.9 USB
25875 USB - center frequency 25.876 MHz or maybe 25876 kHz, another strong data signal
