Some VHF low band activity this afternoon:

29.950 MHz FM - POCSAG paging signal - European paging frequency
30.000 MHz FM - US military comms, extended unmodulated FM carrier signals (around 1923 UTC) too
30.020 MHz FM - POCSAG paging signal - this is a confirmed Canadian hospital paging frequency 30.0200 FM
30.300 MHz FM - Asian fishery radio comms 30.30 FM 30.3000 MHz FM fishery radio
30.450 MHz FM - US military comms Fort Hood, Texas Range Control 30.4500 FM [150.0 Hz]
30.525 MHz FM - Weak FM voice signals, either military or fishery radio chatter
30.550 MHz FM - Asian fishery radio comms 30.55 FM 30.5500 MHz FM fishery radio
30.640 MHz FM - UNID Business User, US stations, English language 30.6400 FM
30.640 MHz FM - Spanish language taxi dispatch
31.000 MHz FM - Business land mobile comms, southern US accents 31.0000 FM 31.000 FM
31.120 MHz FM - Local business land mobile comms - school bus - van pool transportation dispatcher 31.1200 FM
31.325 MHz FM - Data signal - sounds sort of like ROS mode - French traffic signal control data radio link
31.350 MHz FM - US military comms, 31.35 FM - heavy fading
31.520 MHz FM - Business land mobile user, Spanish language, likely taxi cab dispatcher 31.5200 FM
31.675 MHz FM - Asian fishery radio comms Asian language chatter 31.6750 FM fishery radio

Iíve managed to catch a polytone signal (sounds a lot like ROS) on 31.325 and 31.975. 

Apparently these are traffic signal (traffic light) control signals from France. Very low power.  Pretty decent catch during VHF low band opening. 

138
Confirmed via the great folks at the RadioReference skip/tropospheric ducting forum - I am now able to confirm a signal that I'm hearing every time the band is open - 32.180 MHz FM with 77.0 Hz CTCSS.  Spanish language taxi dispatch lady YL dispatcher.


32.1800 MHz FM - 77.0 Hz - Alajuela, Costa Rica Taxi Dispatch - confirmed use
32.1800 MHz FM - 141.3 Hz - Alajuela, Costa Rica Taxi Dispatch - confirmed use

Also 31.2000 MHz FM - 203.5 Hz - Spanish speaking taxi dispatcher - apparently this frequency/tone/user has been logged since at least 1988.  31.200 MHz FM 203.5Hz is still active, I last heard it myself a couple days ago - the same time that 32.180 MHz was coming in very strongly and the 27.5-39.5 MHz Dedicated Fisheries Radio VHF low fishing fleet chatter out of Asia was coming in on 29.775 MHz FM, 30.300 MHz FM, 30.775 MHz FM, 30.900 MHz FM, 31.100 MHz FM, 31.800 MHz FM and other frequencies. 

I did some more searching, and a lot of folks have monitored these comms, including on 29.875 MHz FM, and numerous additional frequencies in the 30-35 MHz portion especially, all with the 25 kHz channel steps, and never with a CTCSS or DCS tone/code.

139
26765 AM - 26.765 MHz AM is coming in almost daily now, same with 27755 AM - 27.755 MHz AM.  Both of these are confirmed taxi dispatch frequencies for Matamoros Mexico.

Also frequencies

26905 AM - 26.905 MHz AM - Taxi dispatch - Mexico City (Mexico, D.F.)
27765 AM - 27.765 MHz AM - Taxi dispatch - Mexico City (Mexico, D.F.)
27775 AM - 27.775 MHz AM - Taxi dispatch - Mexico City (Mexico, D.F.)
27785 AM - 27.785 MHz AM - Taxi dispatch - Mexico City (Mexico, D.F.)
27815 AM - 27.815 MHz AM - Taxi dispatch - Mexico City (Mexico, D.F.)

Among many others, I'm sure.  27.785 MHz is an interesting one, since it's only 3.75 kHz away from UK FM CB channel 19, which is 27.78125 MHz (or 27.781 MHz, or 27.781.25 MHz or 27781 FM 27781.25 FM...).  The other day I actually heard the taxi dispatch lady on 27.785 MHz AM mixing with UK FM CB signals on 27.781 MHz FM!

10/11 meters / 11m Band Activity 30 DEC 2022
« on: December 30, 2022, 1311 UTC »
Checking the eastern and central European SDRs this morning, along with East Coast USA SDRs, looks like Latin American chatter is already starting to pop up on the usual in-band channels.

On Polish and German SDRs, noting POCSAG pager activity on 26.500 MHz, 26.550 MHz, 26.600 MHz, 26.650 MHz, 26.695 MHz, 26.700 MHz, 26.745 MHz, 26.750 MHz, 26.800 MHz, 26.900 MHz, 26.940 MHz, 26.945 MHz, 26.950 MHz, 26.955 MHz, 27.300 MHz, 27.350 MHz, 27.450 MHz and 27.845 MHz and offset frequency 27.847 MHz / 27.848 MHz as well as 27.850 MHz.

10/11 meters / 11m Band Activity 29 DEC 2022
« on: December 29, 2022, 1325 UTC »
Noting some FM voice on 27275 (CB Channel 27) and 27295 (CB Channel 29).

Also the usual Latin American frequencies are starting to light up, including


26525 LSB 26.525 MHz LSB - alternate frequency (likely stations that QSY'ed from 26.555 LSB)
26555 LSB 26.555 MHz LSB - SSB calling (low channels)
26585 AM 26.585 MHz AM - Mexico
27065 AM 27.065 MHz AM - Very big signals (CB Channel 9)
27455 USB 27.455 MHz USB - SSB calling (high channels)

Some very faint POCSAG paging signals noted on 26.695 MHz. 

The usual FSK bursts on 27.255 MHz RCRS channel / CB Channel 23

Nothing on 27.195 (yet) but I imagine the MFSK multi-frequency data signal will show up there as well.

With the recent band openings, I've done some research and in addition to the dozens upon dozens of pagers in the 26-28 MHz band and 29.7-30 MHz band, the UK use

31.725 MHz
31.750 MHz
31.775 MHz

and I've noted POCSAG signals on 31.75 MHz with just a handheld scanner and a telescopic antenna (CB/11m/10m base loaded antenna, roughly 50" long fully extended). 

Looking forward to more band openings on 11 meters, 10 meters, the VHF low band and 6 meters.  Lots of interesting signals in the 26-28 MHz, 29.7 MHz to 30 MHz and 30-50 MHz low band coming out of the UK, Europe, Latin America...

149
11m and 10m are both extremely busy.  Checking VHF low band now...noted Fort Hood Range Control on 30.450 MHz FM 30.450 FM.  Good signals.


150
Heard locally (using a handheld scanner!) and via the N1NTE KiwiSDR.

POCSAG bursts on 31.75 MHz 31,750 FM 31.750 MHz FM.  Fading in and out.  Known use in Europe.  12.5 kHz steps...but right now 31.75 MHz seems to be the active one (or the strongest one).
