[Spooks] Russian E07 "English Man" number station at 13363 kHz (long message with preceding, strange test transmission)

Russian E07 "English Man" number station at 13363 kHz (long message with
preceding, strange test transmission). I tuned in early to catch this
number station and caught a rather strange test transmission on frequency
prior to the numbers being transmitted. As you can see/hear, it started
with a sound burst, then a strong carrier tone, then what sounds like XPA
polytone sync tones.
