Can anyone confirm - 31.240 DPL 131 references to an accident at route 2 and elmridge road, school buses.
Pretty sure this is First Student Inc in the area of Pawcatuck CT. They have a base there on extrusion Drive.
The route 2 / elmridge intersection isnt that far away.

They used to be (107.2) but that was 2010 for the RI/CT sites

I heard a Dispatch for Columbia, CT on 33.72. Columbia is in Tolland Co, but I'm not seeing a listing for 33.72. Thanks.

That is unusual, we don't have it listed here or at Scan New England. An older copy of the O.S.G. shows the frequency of the "Willimantic Switchboard" which likely dispatched them. Columbia is in Tolland but has always been dispatched from Windham County. Did you catch any PL?

No I'm sorry I don't have a PL capable scanner. Traffic was "I'm going to divert you to 185 Route 87 in Columbia, for a fire alarm then likely have you proceed to station 10 for a cover assignment. "

26.7650 MHz AM - Spanish speaking taxi dispatcher (YL dispatcher) was booming in this morning around 0900 US eastern time. I actually caught it while tuning around the POCSAG paging signals coming out of the UK on/around 26.750 MHz (26.745 MHz and 26.755 MHz are used as well as 26.75 MHz). With my receiver in FM mode on 26.7600 MHz, the YL dispatcher on 26.765MHz AM came in as clear as if she were on FM and I was actually not off-frequency.


I know, wider bandwidth on FM plus slope tuning an AM signal in FM mode. Still, pretty cool to hear the Europe and UK based paging transmitters’ signals mixing in with Latin American land mobile / business comms on 26 MHz. At that point in time, WWV on 25.000 MHz was barely there. This morning 26.9000 MHz was absolutely booming in with multiple POCSAG paging signals on top of each other. 26.700 MHz was busy with a mess of paging transmissions and very strong QRM from freebanders on 26.705 MHz AM (and 26.715 MHz AM). Also managed to pick up some US truck drivers on 27.635 MHz AM mixing together with digimode signals (ROS mode). CB channels 24/25 (27.235 MHz and 27.245 MHz) were full of packet signals and I did hear FT8 on 27.255 MHz (CB Channel 23). Of course, 27.2550 MHz was QRM City with dozens of data signals mixing together with the FT8 and of course AM voice…and SSB voice. Some weak SSTV noted on 27.700 MHz as well (27.700 USB), mixing with UK FM CB Channel 11 on 27.70125 MHz FM. I guess this morning the MUF wasn’t playing as nicely for my particular location/timing/setup as the usual 29.750 MHz to 29.950 MHz European paging systems the 31.325 MHz, 31.6875 MHz and 31.975 MHz French traffic signal control data radio networks or the 31.725 MHz, 31.750 MHz and 31.775 MHz UK hospital pagers weren’t really there.

I didn’t check the 49 MHz UK hospital paging freqs (48.8875 MHz to 49.4875 MHz, 12.5 kHz steps - mostly data [POCSAG] but apparently there are voice pages sent via these as well…I cannot personally confirm that though.

At 1500 local time I checked 25.000 MHz AM, WWV is full-scale. 25.9500 MHz FM coming in nicely and there’s actually a faint carrier on 26.1100 MHz FM too!

At (slightly after) 1500 local time, the European signals seem to be gone, US stations and the Americas/Caribbean in general are still coming in though. Asian Fishery radio on

30.3000 MHz FM [CSQ]
30.9000 MHz FM [CSQ]
31.1000 MHz FM [CSQ]
31.8000 MHz FM [CSQ]

40.6700 MHz FM [CSQ] - Data fading up out of the noise and then back down into it.

36.6000 MHz FM [CSQ] YSD Morse code ID beacon signal - YSD CW ID followed by a tone burst…barely readable at points, but it’s definitely there. 36.6 MHz FM YSD 36.60 FM beacon CYSD Alberta Canada Canadian military

11m 26/27 MHz taxi dispatchers and other land mobile users:

26.9050 MHz AM - YL Taxi dispatcher, previously logged (over the past years and years)

26.9550 MHz AM - YL Taxi

27.1950 MHz AM - YL Taxi dispatcher, Spanish, with heavy RCRS data QRM and SSB voice QRM

27.2350 MHz AM - YL Taxi dispatcher, Spanish, Latin America - alphanumeric taxi IDs, numeric ride/trip IDs. Good copy, CB Radio Channel 24

27.2450 MHz AM - YL Taxi dispatcher - Spanish, heard taxi ID 3A2590 (read as “3-A-25-90”) being called. CB Radio Channel 25

27.2550 MHz AM - YL Taxi dispatcher, Spanish, heard basically daily with tons of data QRM. CB Radio Channel 23

27.3250 MHz AM - YL Taxi dispatcher - another poor frequency choice - CB Radio Channel 32
27.4150 MHz AM - YL Taxi dispatcher, Spanish - very poor copy due to heavy SSB QRM

27.4450 MHz AM -YL Taxi dispatcher, Spanish - Mexican accent…alphanumeric (N-A-NNN format) taxi or ride/trip identifiers, similar to the format used on 27.245 MHz AM

27.4850 MHz AM - YL Taxi dispatcher, Spanish

27.5150 MHz AM - YL Taxi dispatcher, Spanish / very poor frequency choice….this is heavily used by Caribbean 11 meter freebanders (usually 27.515 LSB)

27.6450 MHz AM - YL Taxi dispatcher, Spanish

27.7750 MHz AM - YL Taxi dispatcher, Spanish

27.7850 MHz AM - YL Taxi dispatcher, Spanish language

27.8050 MHz AM - YL Taxi dispatcher, Spanish, very heavy SSB QRM

27.8150 MHz AM - YL Taxi dispatcher, Spanish - numeric IDs, addresses heard

27.8850 MHz AM - YL Taxi dispatcher, Spanish, Mexican accent, heavy interference from POCSAG-like data signal on/near this frequency (possibly 27.890 MHz or 27.880 MHz)

27.9150 MHz AM - YL Taxi dispatcher, Spanish, numeric identifiers of some type heard

26.140 MHz was likely pagers. I know the UK uses 26.150 MHz for on site hospital paging (POCSAG mode). 25.855 MHz could have also been a pager system, a data link, or a taxi dispatcher with multi-tone end of transmission (EOT) tone burst (also known as a “Roger Beep”).

See: and


25.6150 MHz to 26.955 MHz, basically every 10 kHz. The 25 MHz band and 26 MHz band, especially the lower parts of 26MHz and the higher parts of 25MHz are jam-packed.

What did you hear on 25.8800 MHz?

The other possibility is the Waverider Buoy (Datawell Waverider). They’re telemetry transmitters that operate in the 25.5 MHz to 35.5 MHz band, using FSK transmission modes. Usually the frequencies are random offsets like 27.828 MHz or 25.777 MHz or 34.7325 MHz and so on. There are numerous FSK signals on the 25.5 MHz to 28 MHz band and 29.7 MHz up past 35 MHz. Also, there are still fishing net buoys or radio-buoys (driftnet) that transmit a CW ID, 5 kHz steps on 26 MHz and 27 MHz. Many more of these are in the 1.6 MHz to 4 MHz (1600 kHz - 4000 kHz range).

Re: the 26.765 MHz AM Taxi Dispatcher in Matamoros, Mexico 26.765MHz 26.7650 AM [CSQ]


Mexico City (Mexico, D.F.)

27.755 MHz AM, 27.815 MHz AM and many others



And, of course, the 27.515 MHz AM taxi dispatcher 27.5150 MHz AM 27.515MHz

25.880 Heard AM voice spanish man and female
26.110 tones weak but able to hear them.
25.855 nothing but tones of all kinds went on a good while 20 mins then off.
Thanks for the info on the pagers may have heard them befor!When bands open i tend to hear east/west off my longwire that runs north/south up at 10 feet. Have not heard any FSK yet but will listen for it! The video very helpful.Thanks.Working on better ant. to hear with scanner i use a discone in the attic for now...:)

Regarding 31.1 and 31.8 "Asian fisherman" hits, does anyone know roughly where they are located? Pacific, Gulf? I've gotten a ton of hits on those lately, just wondered what bodies of water they may be sailing.


There's not too much information out there.

hfundergound.com states those frequencies are used in the waters of and adjacent to The People's Republic of China (PRC) and Hong Kong.


Try looking up: China/Hong Kong fishery maps in a Google search.

French Roadway frequencies highly active again today between Approx 8:45am and 10:45am EST. always seems to be within 8:30am to 11:30am window. Dozens of stations heard. Mostly polytones, along with long open carriers, and a single steady tone every once in a while along with brief chatter. Trying to make a list with PL tones. (If you already have a list of all their frequencies or know where to find one please post!! locations too!)

CHP has been highly active as well with hits all day till near sunset.

Try looking up: China/Hong Kong fishery maps in a Google search.

Yes, so the 480 channel 27.500 MHz FM to 39.475 MHz FM “dedicated fishery radio” is out the People’s Republic of China. The radios are channelized, straight sequence…25 kHz spacing. 25 watt RF output. In addition to voice, data transmission for GPS location, fleet call, shore station call, individual ship call and location info are included. The newest version of these radios advertises as “Digital Fishery Radio” with “Encryption For Administrative Fishery Use” and “analog/digital capability”. No other details [at least in English] are available.

I know Japan, South Korea and several other countries have lower-power fishing radio services, Japan has a 1 watt DSB or 1w Double Side Band 27MHz Fishery Radio - another way of saying “1 watt AM”. 26.760 MHz to 27.980 MHz [with some gaps] using very random steps - the system is channelized but the channel spacing ranges from 8 kHz to 10 kHz to 12 kHz to 18 kHz to 40 kHz. Japan has a 25 watt SSB fishery radio that operates in the 27 MHz region [the gap in the 1w AM service]

The fact that the 480 channel 27.500-39.475 MHz system uses FM instead of AM or SSB, has higher power output, more channels to choose from and has many more features….makes it more attractive to a fishing fleet. Plus the radios use simple 3-digit channels 001 to 480 instead of the 5-digit frequency (like the Japanese system does). I know the AM systems are very popular still though.

That might explain its worldwide use. Plus, over salt water…high-HF/low-VHF must give impressive range. Plus, 480 channels. Although I’m sure they avoid using the lower channels (below 29.7 MHz or so) when the band is open due to the amount of activity on 11m/10m, meaning most users are likely operating above 29.700 MHz

So…

27.5000 MHz FM is Channel 001

39.4750 MHz FM is Channel 480

Right through 11 meters, 10 meters and VHF low up to 39.475 MHz. The radios are advertised as “27.5-39.5 MHz Fishery Radios”.

FM voice, carrier squelch [selective calling options, like in the form of multi-tone ANI/DTMF type sel-call exist, as do optional voice inversion boards. Do a Google search for

IC-998
IC-998B
IC-998C
FT-801
FT-801B
FT-998B
FT-998C

or just “27.5-39.5 MHz Fishery Radio”

This service itself is out of the PRC, but Tagalog, Japanese and other Asian languages aside from Cantonese and Mandarin Chinese have been logged on the 27.5 MHz - 39.475 MHz channels. I’m certain that these radios are sold en masse to fishing fleets and that’s that. It wouldn’t surprise me if they’re out in the South Pacific close to South America and elsewhere. Listeners in France have heard activity on 29.8750 MHz FM [CSQ], 29.7750 MHz FM [CSQ] and several of the 30 MHz / 31 MHz band frequencies. Some have reported that they’re used by fishing fleets out of the Philippines and Malaysia as well as [the People’s Republic of] China.

Yes, they sell these radio e.g. here:
On simon the wizard blog they show up in 2014:

Feitong is a brand name.

Perhaps of interest:
Dual signaling operation (300 baud ASK, 1200 baud MSK)
4 channels on duty (channels 221, 231, 236, 238)
