[Spooks] US Number station?

[El Kristo]

Interesting...Tom: 

Do you have any idea if this two-tone DTMF signal is part of the
procedure to send an EAM? Something like <preamble><message><two-tone
DTMF>...

I heard yesterday evening (Pacific time) several messages on 8992.0
USB and boy, were they sloppy!

One operator started without preamble, stopped in the middle of the
message and never came back on the air nor completed the message with
a #9 or any other tone for that matter.

Another operator started with preamble and was interrupted in the
middle of a message by a voice (another ground based station?) asking
if they were in AM or USB...there too,  never came back on the air nor
completed the message, no tone heard.

It went on like for about 40 minutes...Maybe the "newbie" was getting
trained that day...

Chris.
