Guy's Morse Stations Corner

I hope you found the first of the Morse Station information interesting. This month I intend to give some news on recent happenings and expand on the profile of some more of the Morse families.

The end of Month transmissions from M1 in March were very interesting. The Thursday at 1800 caught me out as they changed from the normal frequency to the one used at 2000. It was only a short transmission as it ended at 1807. The transmission at 2000 was characterised by the very long pauses, much longer than usual. The Saturday at 1500 was the opposite, very short pauses, sounded as if the Op was in a hurry to get away.

Now that the clocks have changed to summer time in the UK, some of the stations have changed times. Oddly enough M1 remains at the same time and M1B is on 1 hour earlier. Others on earlier are M12, M17 and M29.

Schedule for M1B as follows, they seem to be getting busier lately.

(Listed as time/frequency/ID)

Monday

1718/5220/719

2010/5804/298

Tuesday

1723/6283/382

Wednesday

Thursday

1500/6823/???

1725/6283/???

2032/5737/931

Friday

1748/4771/168

2102/5235/871

Saturday

1510/5473/745

1605/5350/053

Logs of any other M1B would be appreciated, also the missing IDs

M53

Another to add to the list is M53, not heard since last October when I suspect it changed frequency for the Winter, now back on its usual frequency of 8231 at 2000 and 2100.

Format is
Call Preamble Message
VVV CQ 747.585 R5 CQ585 CQ585 CQ585 HR HR 23 23 = = 23x5f AR AR RPT RPT CQ585 CQ585 CQ585
Repeat Ending
HR HR 23 23 = = Message repeated AR AR VA VA

The call is always 747 with a different ID. The stop in between is sent as AAA the morse full stop. Uses short zeros and is macine sent at 20 WPM. Repeats the same message on the next day. Has been known to send 2 messages but this was only heard once.

An interesting transmission took place on Friday 3 April. Nothing was heard until 2002, then a few blips were sent, then the call and message were sent by hand. First time ever heard hand sent. It seems they must have an operator standing by at each transmission in case the machine goes wrong.

More on M53 to be found in Newsletter 8.

Activity

M12

Still sending the same message on a Sunday at 1840 1900 and 1920. The frequencies, which always end in 67 are 12167 11567 and 10167. The ID this month is 151. Still the same frequencies as in April. This same message has been sent since at least October 1996. Is always the same DK and GC 792 66 and the message identical.

M2

Not heard since 31 October 1997 so presumed ended If it comes on again will list times and frequencies.

M3

Modes usually ICW a few use MCW

Ref Call Preamble Message Ending

M3 044/00 (R5)* No Message = = 000

M3 044/54 (R5)* = = 54x5F = = 000

M3A 552/111/00(R5)* No Message = = 000

(R5)* rarely are (R10) Morse is sent at about 17 WPM except for 503 which is very slow at 5 WPM. That transmission is normally on 10721. Some transmissions sent in MCW.

M3A is not sent very often and the meaning of it is not known could possibly be confirmation of receipt of message. Only triplets of 111 and 333 have been noted.

When M3 send a message after the 54x5F groups the ID is sent again 6 times then the message is repeated as 54x5f groups. 54 single groups Is usually on between 0700 and 1200 on the hour and the half hour. Messages are usually between 50 and 59 groups, possibly so they fit in the 30 minutes transmission time. Repeat transmissions are usual.

Frequencies that have been used are. (Those in brackets in use at present)
3060 3250 3392 3450 3823 3923 4015 4090 4465 4610 4722 4750 4780 (4870) 4900 5050 5090 (5120) 5150 (5180) 5220 (5360) 5365 5409 5550 (5520) 5610 5625 5670 (5830) 5860 5870 (6330) 6334 (6430) 6540 6640 6750 6810 6840 6850 6905 6950 7208 7255 7276 7444 7540 7580 7620 7649 7670 7710 7830 7840 8033 8037 8100 9030 9272 9180 9950 10250 10270 10540 (10721)

IDs heard to date
010 011 012 013 014 015 016 017 018 019 035 040 041 042 043 044 045 047 048 121 183 214 216 282 284 287 312 317 493 496 503 507 508 552 553 558 584 621 629 624 857 741 742 743 976

Traffic for this station varies, sometimes can go for a week without sending any traffic.

Some of the IDs never get a message sent. For example 503 always on 10721, sent very slowly at 5 WPM. If it ever gets a message it will take an age to send. Some other IDs are special transmissions at odd times and perhaps will only be on for 2 weeks. One at present in April is on a Saturday at 0800 on 8187 to 624. Has been on several Saturdays but never sent a message.

M4

U R10 LO LOx3/75977 75977 100x5f Always 100 LO LO/75977 75977 Repeats Message AR SK AR SK

Frequencies used:
3825 4195 5340

This station uses long zeros. Always MCW with quite low level mod. Speed 19 WPM. Activity level of M4 and G2 has recently drastically reduced, at the moment there is only one M4 transmission a month. That is on week 2 of the schedule on Wednesday and Thursday at 1000. Frequency is also unusual for M4 as it always used to be on the same 3 frequencies. This one was on 7250. Another log of M4 on Wednesday 13 May at 1000 on 7250 at 1200 on 8188 and at 1300 on 5748 ID LO LO/29175. Same message repeated

M7

Mode, Always MCW, constant carrier.Speed 17 WPM. Strange call, sounds like letters with long dash. "Letters" used A N U and K, Call is for one minute. Then 749 749 749 85 85 35 35 = = 35x5F = = 85 85 35 35 000 Then one minute of letters with long dash, sometimes same letter, sometimes different letter. Frequencies used, same as M10, Favourite time is Hour+20 although can be heard at any 10 minute interval within the hour. Parallel frequencies never used. It has been suggested that this method is used to activate some unattended recording device. I have heard recently the same ID and message sent both by M10 and M7

Morse activity still remains high, for example on one day I have logged 21 different times from these groups M1, M1b, M3, M8, M12, M13, M14, M17, M23, M29, M45, and M53.

M45

It has changed for May. Is now on at 1703 on 5074 and 5474. ID 704
