[MilCom] Unusual data signal heard.

[KD7JYK DM09]

Several years ago I heard an unsual data signal on 222.000 MHz FM.  I was in 
the basement of a stucco house using an HT with 5" whip, and due to my 
location and fading of the signal assumed it was a satellite.  I asked on a 
satellite list at the time and provided a recording to a few people, none 
could ID it.  A friend provided a nearly identical recording this morning 
with the following note:

"The attached sounds were recorded from a scanner radio, monitoring milair 
frequencies, during an air excercise near Rachel, Nevada. It's not PSK and 
I've never heard anything like it before. Can you tell me what it is? 
Message content, perhaps?"

The signal is a rapid series of tone all over the audio spectrum.  In my 
recording, the tones were slower and static could be heard between them, in 
my friends recording, they are much faster with little time between them.  I 
would describe it as old video game sound effects.

Recordings provided upon request, if someone could host them on a webpage, 
all the better.
