RX is the G8JNJ SDR receiver located in South West UK.  Strong fisheries radio chatter.  Channel 193 on the 480 channel plan Chinese 27.5MHz - 39.5MHz FM fishing boat fleet radios.  Strong FM modulation, two OMs yakking away.  S5 signal strength jumping up to S8 on the peaks.

Strong EPAR data signals noted on the G8JNJ SDR

31.325 MHz 31,325 kHz 31.3250 MHz FM at 1434 UTC

31.975 MHz 31,975 kHz 31.9750 MHz FM at 1435 UTC

22
Tune in time: 1415 UTC.  Seems like the signal is fading out by the time I tuned in. 

Bandwidth approx 6 kHz, seems like a MFSK data signal with a "carrier" signal on 27940 kHz... with "pulsing" sound in AM, FM and SSB.  POCSAG paging signals on top of the data signal.  Unlike the data signal, the POCSAG pager signals are not nonstop. 

Some very strong FM CB radio signals noted at 1418 UTC.  UK FM CB comms, UK FM CB Channel 35, frequency 27941 FM 27.94125 MHz FM 27.941.25 MHz FM.  Severe QRM from the pager signals and data link on 27.940 MHz. 

Aside from being used for land mobile business type comms LMR PMR PLMR taxi cab radio dispatch taxi controllers out of Russia and elsewhere, 27.94 MHz is also one of the 27MHz Australian marine band frequencies.   The Australian 27 MHz marine band is AM mode A3 emission A3E AM radiotelephone maritime mobile service ship to ship ship to shore 

27.680 MHz   Commercial, Calling ship-ship, shore-shore - 27MHz marine channel 68 CH68
27.720 MHz   Pro. fishing, Calling ship-ship , shore-shore CH72
27.820 MHz   Pro. fishing, Calling ship-ship , shore-shore 27 MHz AU marine radio channel 82 CH82
27.860 MHz   Distress, Safety & Calling (supp. to 27.880) CH86
27.880 MHz   Distress, Safety & Calling Emergency Channel 27.88MHz - 27MHz marine channel 88 CH88
27.900 MHz   Non-commercial, Calling & ship-shore 27.9 MHz channel 90 CH90
27.910 MHz   Non-commercial, Calling & ship-shore 27.91 MHz CH91 Channel 91
27.940 MHz   Non-commercial, Calling & ship-shore/ship 27.94MHz 27,940 kHz 27940 kHz channel 94 CH94
27.960 MHz   Non-commercial, Calling & ship-ship 27.96MHz 27 MHz marine channel 96 CH96
27.980 MHz   Rescue etc., Calling & ship-ship, shore-shore 27.98 MHz - 27MHz marine radio channel 98 CH98

Those are the official channels, with private marinas, SAR, sea rescue, etc. organizations often using additional private channels in the 27.500 MHz to 28 MHz range (eg. 27.70 MHz, 27.75 MHz, 27.76 MHz, 27.80 MHz, 27.84 MHz, 27.85 MHz, etc.)

10/11 meters / Re: 11m Band Activity 4 JUN 2024
« on: June 04, 2024, 1414 UTC »
Band is open!  At least on the European based online receivers (including UK in "European"). 

Lots of paging signals noted, plus plenty of Italian CB comms, including 27.465 MHz AM mode or Canale 45 (Channel 45), basically the Italian version of 27.025 MHz AM (CB Channel 6, the "Superbowl") and/or 27.085 MHz AM / 27.265 MHz AM / 27.285 MHz AM - big radios, lots of modulation. 

24
Listening to CADS / WPAS parish radio broadcast on UK FM CB channel 16, frequency 27751 kHz FM 27751.25 NFM. 

Strong audio, some very minor fades.  SIO 444.  S9 on peaks, mostly hovering around S7-S8. 

At 1925 UTC, you can clearly hear the church background audio, people talking, a sporadic cough...other background chatter.   

Some minor QRM from SSB chatter on 27.745 MHz USB as well some weak SSB chatter on 27.755 MHz LSB.  27.75125 MHz FM is the strongest signal by an order of magnitude though.

Substantial fade down to S5 at 1927 UTC...followed by a nice jump up to S9+10dB for a few moments.  Full quieting FM signal, very good audio especially considering this is 2 or 2.5 kHz deviation! 

CADS / WPAS channel LW16 FM or UK FM CB 27/81 FM CB channel 16. 

Bandwidth at highest FM deviation around 8 kHz or 9 kHz or so.  Can safely call this 10 kHz bandwidth. 

25
Via G8JNJ SDR receiver.  29875 FM [CSQ].  Carrier squelch, no CTCSS (PL) or DCS (DPL) in use.  CSQ. 

Very strong signals, sounds like Japanese language chatter on 29.875MHz.  One of the more active Asian fishery frequencies, 29.875 is Channel 100 on the 480 channel 27.500 MHz - 39.475 MHz [25 kHz steps, sequential channel numbering) radios.  29.825 MHz, 29.900 MHz, 29.925 MHz, 30.025 MHz, 29.775 MHz, 29.750 MHz and many others are also very popular.  29.825 MHz and 29.875 MHz are both in the "top 10" both locally for me here on the East Coast of the USA and via remote receivers located in the UK and mainland Europe.  One of the characteristics of these systems is the use of 25 kHz or 12.5 kHz spacing frequencies and carrier squelch.

Fishing boats?  Did they have a New England accent? 

Nice catch, 6967 kHz USB could be one of any number of things (or, more than likely, it is free band / out of band operators)

Interesting frequency choice.  Whistling is pretty popular as a "selective calling" method over HF SSB marine nets. 

8281.2 kHz does fall within the legal 8 MHz marine band allocation 8195 kHz to 8895 kHz 8.195 MHz to 8895 MHz. 

Going by the ITU channel plan / band plan, 8282 kHz is the closest "channel" but those are more like guidelines than rules. 

8282 kHz is part of the ITU dual use (simplex for ship to ship, duplex or "split" operation for ship to shore radio) channel plan, specifically channel 830 frequency 8282kHz USB 8.282 MHz USB (ship transmit) paired with 8806kHz USB 8.806 MHz USB.  For ship to ship purposes, using a single frequency is the common practice, and makes the most sense.

The ITU actually only has a handful of designated simplex frequencies on the MF and HF frequencies:

Most of them are in the 2 MHz and 4 MHz bands.  8MHz band only has 8294 kHz and 8297 kHz, plus numerous frequencies in the shared fixed/mobile allocation 8000 kHz to 8195 kHz sub-band: 8101 kHz to 8191 kHz - much like the 4 MHz simplex frequencies 4000 kHz to 4060 kHz (3 kHz spacing - 4000 kHz USB, 4003 kHz USB, 4006 kHz USB, etc.)

These are apparently part of Russian military channel markers (well, a new series of channel markers).  Music (including the Soviet National Anthem, a rock version of the Soviet / Russian National Anthem, various WWII (sorry, I meant The Great Patriotic War) patriotic songs including the famous "Katyusha", sound effects including buzz buzz buzz (think UVB-76 / "The Buzzer" on 4625 kHz), an air raid siren, an alarm, what sounds like a tennis racket or ticking clock or other similar sound, the "pip" and other feeds. 

At various times, the recording loop is cut off and messages are sent.  These signals have been heard by numerous listeners and a large number of them are on YouTube

They've been logged on:

4675 kHz USB
5780 kHz USB
5838 kHz USB
5838.5 kHz USB
6180 kHz USB
6218 kHz USB
6230 kHz USB
6318 kHz USB
6322 kHz USB
6330 kHz USB
6402 kHz USB
6911 kHz USB
6930 kHz USB
7032 kHz USB that's right, more Russians in 40 meters!  7.032 MHz USB 7,032 kHz 7032kHz USB
8001 kHz USB
8514 kHz USB
9001 kHz USB
9041 kHz USB
9310 kHz USB

I'm sure the list above is incomplete.  I'm not including 7050 kHz LSB and 7055 kHz LSB...plus the dozens of other frequencies used by the Russian military.  Yes, 7032 kHz is in USB mode, not LSB mode. 

I can confirm that 6910 kHz USB, 6930 kHz USB, 6218 kHz USB and 6230 kHz USB are active as of 28 May 2024 (listening via a UK based remote SDR receiver).
