Today, looking through the latest Enigma newsletter (En55), I was able to match up a broadcast I recorded back on 9-26-09 / 6874 AM / 00:33z-00:39z - this apparently was an E06 transmission. I thought it was a pirate doing a spoof originally, but it fits the schedule/frequency listed in the newsletter.

I checked my recording against the audio files of the Conet Project and it matches up with the X06 version on the cd. X06 uses a 6 tone rising scale & apparently has no schedule. Both of these guys are products of Russian intelligence.
