[Spooks] "Polish Pip"

[Ary Boender]

Hi Lars,

The Polish Pip is a RS10/BRAS-3 hyperbolic navigational station. It is
part of one of the chains in the Baltic area, most likely the Kaliningrad
chain. In the past there were much more chains, but the number decreased
in the past 10 years. At least two or three chains are still on the air.
The freq range is too noisy here to nail down all the active freqs. Can
you tell me on what freqs you hear the signals?

The Liepaja Bras, and Taran (with Rozewie) & Kursiu RS-10 chains were
closed in 1991.

1680 : BRAS-3/RS10 Kaliningrad chain
1684 : BRAS-3/RS10 E.Gulf of Finland chain
1810 : BRAS-3/RS10 probably part of the Kaliningrad chain

Freqs +/- 2 kHz. Each chain has it's own pattern.

73, Ary
