Ah Another Member of the Old Pharts Club by the sound of it .
I remember looking on it as mysterious & magical , all this stuff going on around the world , as you say , and on Short Wave or was it VHF ? Did we get VHF then?
anyway there were broadcasts in English from I know not where , I think there was a US station that drifted in sometimes , other than their forces network , may have been CBS European Radio or something . Used to be able to follow the police radio , you found the frequency of the despatcher then search quickly for one of the cars.
Luxembourg was the first "pirate" really, programmes were made in London I think, then broadcast from Luxembourg complete with advertising, all together now " We are the Ovaltineys , little girls and boys...." There was Double your Money with Hughie Greene and Take your Pick .
You couldn't receive it until around 7.00 PM , something to do with signal strength .... the big thing with us young 'uns was they were the only station that played Pop music & Rock n Roll so if you wanted to hear the latest from Elvis , Ricky Nelson , Eddie Cochran or Dion & the Bellmonts you tuned around 10pm to the Teen & Twenty Disc Club presented by your friend and mine , the schoolgirl's favourite ...lets hear it for Mr Jimmy Saville (among others ).
Commercial radio didn't exist elswhere....there was no R1 , there was the Light Programme , the Third Programme and The Home Service & BBC World Service.
It wasn't all bad ... all the family would sit round to hear Journey into Space or Paul Temple and the Mysterious Whatever Mystery on BBC
