[Spooks] Vintage German lady number station

[Pavel Troller]

Hi!
  Inspired by a recent thread about a vintage number station, I searched my
old tapes (I have really LOT of them, hundreds of reels, mostly with music,
but sometimes with other interesting things) and finally found a short
snippet of a German number station transmission. There is neither start
nor end of the transmission, just a few 5-digit groups.
  It was recorded sometimes between 1977 - 1980, at my cottage near
Ceska Lipa, Czech Republic (but it was Czechoslovak Socialistic Republic
these times). Reception was made on a Czechoslovak tube receiver "Barcarola"
http://www.radiomuseum.org/r/tesla_barcarola_1009a_1009_a.html
on a shortwave band with classic AM (of course this rcvr was not capable
of SSB or any other advanced modes) using a random wire (about 10 m)
antenna. As you can hear, it was perfect, clear readability.
  A recording was made on the B400 Czechoslovak tape recorder
http://www.radiomuseum.org/r/tesla_b400b_40_anp222anp_22.html
using a Scotch 220 magnetic tape (exactly the one which is on the picture),
speed 9.53 cm/s.
  Import to the digital domain was performed using the Audacity open source
sound recording and processing software, without any artificial filtering
or other DSP techniques.
  Finally, the link to the recording:

  I know that because the recording is incomplete, it has just a low value
as such, but maybe it can at least demonstrate, which kind of equipment
was obvious at this time and that it was possible to use it for activities
like SW listening and number station (at least the strong ones) monitoring.
  I'm curious, whether somebody will identify the station.
With regards,
  Pavel
