Fishnet Beacons (Radio Buoys) Long Keydown + Morse IDs 9 April 2025 [G8JNJ SDR]

[R4002]

Received via G8JNJ SDR today 9 April 2025, around 1300 UTC - 1305 UTC.

Frequencies given are carrier frequencies, if you're tuning in USB mode, its 1.4 kHz or 1.5 kHz down in frequency (or 2 kHz down, to make things easier) - so 26.878 MHz or 26.879 MHz instead of 26.880 MHz).  I've heard of these things being heard on the 26 MHz NZ CB band (26.330 MHz - 26.770 MHz - the NZ 26 MHz band follows the regular 26.965 MHz - 27.405 MHz CB band plan, just all channels are -635 kHz).  Given that these things seem to mostly follow a 5 kHz step band plan, that makes sense. 

All the signals feature a multi-second tone burst (or just carrier keydown), followed by a CW identifier.  The signals are all regular old CW, not modulated CW.  I should just call them Morse code fishing net driftnet beacons.   There are several FSK beacons also active, which are likely the same concept only they're transmitting a GPS location via fast FSK.

26.350 MHz - UNID driftnet beacon, unable to copy due to POCSAG paging signals on frequency

26.788 MHz - FSK driftnet beacon (FSK bursts)

26.822 MHz - FSK driftnet beacon (FSK bursts, exact same time as the 26.862 MHz signal)

26.838 MHz - FSK driftnet beacon

26.840 MHz - MI in Morse Code

26.862 MHz - FSK driftnet beacon (FSK bursts, exact same time as the 26.822 MHz signal)

26.880 MHz - Long keydown, followed by "NMN" in Morse (poor copy)

26.880 MHz - Long duration tone burst, followed by "UTS" in Morse Code

26.885 MHz - Long duration tone burst, followed by "RR" in Morse Code

26.890 MHz - Long duration tone burst, followed by "PCE" in Morse Code (possibly multiple beacons on this frequency)

26.890 MHz - Long duration tone burst, followed by "ECE" in Morse Code (this could be a copying error on my part)

26.895 MHz - Shorter duration keydown, followed by "IU IU" in Morse Code
short short    short short long
26.965 MHz - Long duration tone burst, followed by "PCE" in Morse Code (very similar to the 26880 signal, likely part of the same network?)
