     Call                 Preamble            Message       Ending
 555x3 571x3 46 (R5)   571x3 75 75 46 46 = =   46x5F  = = 75 75 46 46 000

They can have up to 4 IDs in the call, in this case the call would be

555x3  571x3 46 275x3 25 049x3 16 435x3 41 (R5)
Then the preamble would be the same, message the same but the ending misses
off the 000 and carries on to the next call which would be 275.The message
can also sometimes be split into 2 parts with a different decode key for
each part, but in this case the call gives the total amount of groups in
the message.

This station uses a slightly different format of 2
figure decode key.The call up usually starts with 555 but they have been
known to use other triplets,111 222 333 444 777 and 888. These are used on
special broadcasts. They have also be known to use up to a 4/5 figure
random ID, but only very rarely. Transmission times and frequencies are
changed quite often, although they use a set of frequencies to choose
from.Sometimes they use 2 frequencies but not always. Regular schedules all
use 2 parallel frequencies.
The speed the message is sent is variable, usually the later message is sent
at a faster speed.Call and first message 17 WPM later messages up to 25 WPM.
