New Asiatic M12, Mondays and Fridays, April 2019
« on: April 26, 2019, 1205 UTC »
This past Monday (April 22, 2019) at 0050z on 12137 kHz I stumbled on a new, to me, and as far as I know previously unreported, Russian M12 numbers station transmission.  The callup was 891  891  891 891  1, indicating the 0050z transmission I heard on 12137 kHz was probably the last of three transmissions that day, with earlier transmissions at 0010z and 0030z on higher frequencies, with 100's digit of 8 and 9 and last two digits of 37.

So began the hunt, each night, to determine what days this station is active.  For M12 it is common for their to be two active days per week for a given schedule.  ANd this morning I found the other transmissions.

It appears the schedule is on Mondays and Fridays, at 0010z, 0030z, and 0050z, on frequencies of 14837 kHz (at 0010z), 13937 kHz (at 0030z), and on 12137 kHz (at 0050z).

Unfortunately, we are near the end of the month, and there is only one more day this month this station should be active on this schedule, that would be next Monday, April 29.  After that it will still probably be active on Mondays and Fridays, but on a new set of frequencies, and possibly in a new time slot, will have to search next Friday to find the new schedule.

It is very likely that this Monday / Friday M12 is transmitted from the same location as the other known Asiatic M12 on Tuesday / Thursday, and the V07 on Sunday.  There also used to be another M12 from the same source on Wednesday and Saturday, but as far as I know that schedule is no longer active.

For May of 2019 this station has shifted time 2 hours later, starting now at 0210 z on Mondays and Fridays.  This change fits the operating habits of other Asiatic Russian signals, like V07 (Sundays) and M12 (Tuesdays and Thursdays).  This station also tunes up the transmitter with BC station audio present, as does other Asiatic Russian numbers stations.  This supports all of the currently active / reported Asiatic Russian stations being from the same source, in Kharbarovsk, Russia.

May 2019 Monday / Friday Asiatic M12 schedule:
0210z    13426 kHz
0230z    12126 kHz
0250z    10226 kHz*

* Note, I have not yet observed the 0250z transmission occur, so far in May all transmissions have been nulls, and so no third time slot activity.  However, 10226 kHz fits the operating habits of this station, and is a "best guess" projection until an actual transmission occurs.  Other possibilities for this time slot are 11226 and 9226 kHz, however 10226 is the most likely.

13 May 2019, 0250 UTC - 10226 confirmed. Got it with a fair signal here in Denver, sounds much better on KPH kiwi SDR in California (the 3-30 MHz one). I had it weakly for a bit on 12126 at 0230z but it faded. I have no chance at copying such fast CW.
