Tomorrow evening, February 9, 2017 at 1710 EST and 2140 EST in the vicinity
of 3570 kHz there will be a short agent message transmission. 53 five letter
groups will contain a plain text message beginning and ending with a group
made up of five "V" characters. The message will be sent twice. The message
will be preceded by QST QST QST MRCA Code Practice DE KW1I sent three times.
The CW is machine generated and is less than 10 WPM. The total transmission
time is ten minutes. The signal should be able to be heard in most of the
Northeast. This is an opportunity to go through the motions of receiving a
clandestine message sent to agents by an espionage communications center. If
it is a little faster than your code speed, record it and play it back
several times so you can decode it all.  After receiving the message
reassemble the message from the groups. If conditions are good, try
receiving the message on a small agent set with a compromise antenna.  

Feedback on this exercise is invited. All responses should be emailed to the
MRCA Reflector which is constantly monitored by the MRCA Clandestine
Communications Center.

Notice of additional broadcast of this message and follow-on messages will
also be via the MRCA Reflector.
