Title: Unid data tones 6925-26
Post by: Zoidberg on April 13, 2011, 0004 UTC

4/12-13/11
6925-6925
Since around 2355z (now 0005z), hearing weak continuous data tones, possibly SITOR or RTTY, not sure.
0008z: A little stronger now, seems to have two peaks like FSK or PSK (via MMSSTV waterfall)

Pretty sure I heard the same thing about an hour or two ago. Sounded like data transmissions. Also picked up what sounded like some military talk a bit lower (around 6903) followed by data transmissions.
