the M42/Fapsi stations are still there and the amount of activity
has not dropped. They have however changed their operational
habits a little. The automated broadcasts here in Europe have all
vanished (identifiers: KUL/RAU/VKX etc.) but the individual point
to point links between Moscow and it's embassies are still present.
I am sure this applies to the one way brodcasts originating from
the Cuban relay as well.

If you look at my logs on WUN, you will notice a wide variety of
entries ranging around these stations. They may be a bit harder
to identify these days, as there has been a shift from Baudot to
the 32-tone MFSK mode known to Hoka users as Crowd36 and a narrow
band parallel tone PSK modem sounding somewhat like MT63.

The traffic however seen on these MFSK (and probably the PSK) circuits
is exactly the same as the one noted on the old Baudot links.

You will see the same 11177/11166/11144 preambles followed by the
individual link IDs. Even if the mode has changed, the contents are
still the same -> 5 letter groups, 5 figure groups and on some links
they have offline crypto which is not divided into 5LGs.

Additionally they seem to have abandoned some of their old channels,
as a result of the high solar activity. I have noticed that the EUR
portion of the net has the tendency to use frequencies in the upper
portion of the HF spectrum during daytime. So look for them in the
17-21 MHz range during daylight hours.
