Default Stratovision!

Getting TV signal coverage into remote [and maybe hostile] places was a big issue in the last century.

Before satellite-broadcasting became a thing, there was Stratovision - TV broadcasts sent from high-altitude aircraft.

Tests were done in the late-1950s/early-1950s.

I find this deeply fascinating.

It became reality later e.g. TV Marti to Cuba used a blimp balloon and a C-130 aircraft;

There was a time when you could get overreach on the telly or on radio. Way back in the sixties in Blackburn you could on a good day watch German television (First watched Raumschiff Orion once) and again when moved to Germany I could on rare occasions watch British TV.

Yes, in times-past during the summer, TV-DX on Band-I was kinda fun; I remember seeing Spanish horse-races and Italian soap-operas, using a 5-element beam on a 60-foot mast.

[Some of my friends based in Germany back then had rather better gear because they had to monitor East European TV on a continuous basis as part of their job.. I remember them watching the DDR "Polizeiruf 110" series.]

Maybe this is 'stratovision' the other way round, with the receiver in the aeroplane. What type of set is this?

Apolgies for going slightly off topic but Bletchley Park computer museum had a high powered transmitter recovered from a Vulcan bomber. It looked like a large cylinder abut 1 x metre tall & it's function (I believe) was to jam enemy radar.

Urban legend has it, that during a training mission in the UK, it was either tested or accidentally switched on resulting blacked out TV reception for miles.

Now that's what i call Strato RFI !
