Andy,
  From Brian Keyete:
RECOGNISING THE STATIONS You will find that Navtex messages start with
'ZCZC' and end with
NNNN. The ZCZC is followed by two letters and two numbers - e.g. OA12.
The first letter gives you a
good idea which Station you have received and it tells you the times
of day, 4 hours apart, when that station
is likely to transmit. Most of the 'O' stations transmit starting at
02:20, then 06:20, 10:20, etc. The World is
split into Navtex areas and there is usually only one Navtex station
using each letter in each area. In North
West Europe (Area 01) an 'O' station heard on 518 kHz is likely to be
Portpatrick in Scotland, but it might be
from Malta (Area 03) or even St Johns in Newfoundland (Area 04). You
need to look at the actual
messages to be sure which of the possible stations it is - the
messages may include the Station Name (e.g.
'MALTA RADIO'), or the Navtex Area Number or geographical references,
latitude/longitude, etc. The
second letter (A) tells you what kind of message it is and the rest
provides a message number.
