Strong signal in SW England. Not sure if this is unlicenced or not, so posted it here.

This has been reported as beacon "M23". Quoting from http://www.numbersoddities.nl/En123.pdf

"Peter, (PoSW), also managed some extensive monitoring of the M23 activity & his detailed report is included below in full;
M23 CW on 5345:- by PoSW
The daily M23 CW sending a slow, “ST3” for twenty minutes starting at around 0857 UTC and again at 1857, continued over into the New Year, starting a second
or two earlier with each passing day, the early sending always a strong signal and the later one usually much weaker. Last appeared on January 15th but M23 had
not gone, found on the following day with a new modus operandi:-
15-Jan-21, Friday:- 0855:39s UTC, starting up with “ST3”, strong signal. No sign of the later transmission on 5345 kHz when checked at around
 1900 UTC.
16-Jan-21, Saturday:- Nothing heard on 5345 at 0856 UTC. However, M23 showed up later in a different guise:-
 1158 UTC, strong M23 sending 3 x 3 dash , i.e. “OOO”, stopped after 1210 UTC.
17-Jan-21, Sunday:- 0755:35s approx. earlier transmission of “OOO”, strong signal, stopped 0810:34s UTC.
 1155:35s UTC, “OOO” again, stopped 1210:34s UTC.
18-Jan-21, Monday:- 0759 UTC, in progress with “OOO”, strong, stopped at 0810:33s UTC.
1204 UTC, in progress with, “OOO”.
Changed again on the following day:-
19-Jan-21, Tuesday:- 0755:30s UTC, “OOO” until 0810:32s.
1102 UTC:- transmission in progress an hour earlier than expected, still “OOO”, stopped at 1115:40s UTC.
Nothing heard at 1200 UTC, however there was an evening transmission:-
2002 UTC, “OOO” in progress, stopped 2015:40s, weak signal.
20-Jan-21, Wednesday:- 0703 UTC, also an hour earlier than of late, stopped 0715:36s UTC.
The schedule now appears to be fifteen minutes of “OOO” starting just after 0700, 1100 and 2000 UTC. Heard at these times daily, last appearance of all three on
25-Jan:-
25-Jan-21, Monday:- 0700:28s UTC, weak signal, stopped 0715:29s.
1100:29 UTC, strong, stopped 1115:29s.
2000:28s UTC, unusually strong for this sending, well over S9, stopped 2015:29s UTC.
26-Jan-21, Tuesday:- 0700:27s, “OOO” until 0715:26s.
No sign of a transmission at 1100 UTC. Monitored until approx. 1105z, nothing heard but was active when checked about ten
minutes later:-
1115 UTC, strong slow CW sending the letter “S”. Stopped after 1144z.
Nothing further heard on 5345 on the remaining days in January but M23 was back in February with a transmission of much longer duration:-
01-Feb-21, Monday:- 1707 UTC, M23 in progress on 5345 with “OOO”, strong signal, stopped before 1723 UTC. Assumed to have started at 1700z
 but monitoring on following days showed this was an under-estimation by one hour!"

1425 UTC Back again.
Because of the time of day I'm not convinced this beacon is located in Russia. It seems way too strong while skip on this frequency is still short. It's almost end-pegging the S-meter.
It has to be located in Western Europe.

Pigmeat That'd be a great DX catch, a tracking device on a moose. :)

I'm sure they've got them in Eastern Canada and New England.

My cousin worked for the Dept. of Natual Resources from the time he left the Army until he retired a few years ago. His first few years at it was introducing wild boars in near vertical terrain. He said that was one of the few projects he worked on he was happy not to see succeed. Why? Bear's were making a big rebound in population. We're one of the few states in the upland South where the bears out produce boars. His personal conclusion was the bears were outcompeting the boars as you could always find sign of bears but rarely see any signs of boars.

I've seen video footage in late winter when DNR agents are out doing their early mom/cub counts. They locate the dens with UHF Yagi antennas and scanners and drag them out. It's not something I'd want to be doing no matter how out of it in their sleep cycles they are.
