Tropospheric propagation?
It was (only) used for military communication via Tropo-Scatter within 
the Warsaw Pact, with Moscow.

That was shortwave here and not decimeter or centimeter waves.
The location was just ideal because of the skip distance of the short 
waves for reflections in the ionosphere.
The entire Soviet controlled area from the Balkans, further towards 
Moscow, further towards the Urals were in the main beam direction.
A location on the beach was ideal:
- no immediate obstacles in the immediate vicinity at flat radiation
- no human dwellings in the immediate vicinity of the main emission 
- but that probably wouldn't matter. From Franco's point of view, it 
would only have contaminated the "unpopular Catalans" with radiation anyway.

See the skip/target areas:


Here is another documentary in Catalan, but with English original sounds:
- very good documentation, most of it can be understood if you are 
familiar with Romance languages
- a senator for Galicia is also interviewed. But he answers in Spanish, 
not in Galician. ;-)
