[Spooks] Possible pre-S28/Buzzer message on different freq

[Token]

Howdy all,

I am not one for following the S28/Buzzer much, but today I noted something
that might be interesting.

Several times today the S28/Buzzer had voice messages.  One of them was at
1430 UTC.  About 1425 UTC I caught a message on another frequency in a very
similar voice and format.  Different message, different ID, naturally
different frequency, but very similar format.

02/21/2011, 1425 UTC, 6409 USB, complete message sent twice.  I did not get
a complete recording of the first half, but I did of the second.
