[Spooks] New Cuban Mixed Mode transmissions

[Beaumont, Paul]

Hello Spooks,

Those of you who follow M08a and/or V02a sendings will be aware of the new Cuban Mixed Mode of V02a and SK01.

The salient point of this apparent new mode being six five number group header repeated circa 2m50s then each header group being announced with a variable length SK01 transmission after, meaning the actual message is a hybrid sending of both V02a and SK01.

We have allotted a tentative ENIGMA ID to this new mode:

HM01 [Hybrid Mode 01].

A fuller description will appear in the next Newsletter.

Please update your ENIGMA Control Lists.

We would be interested to learn what other freqs this mixed mode transmission appears on.
Thanks to all members who have already offered input on this new mode.
