What if it had been done from aircraft? A team of aerial bestrewn C97s perpetually holding station over the Baltic refuelled in flight by KC97s (until they ran out of engine oil).
They would of course be known as the Stratocasters...
Hehehe, nice one. 
The USAF did that for real at one stage too. There was a bunch of specially equipped C-130s flown by an ANG unit that really were airborne radio stations. They had massive 'tanks' outboard of the Herk's usual tanks, and some very weird blade shaped aerials out toward the wing tips.
EC-130J Commando Solo, formerly known as Volant Solo and using EC-130Es. They can broadcast TV as well as FM radio. Article here:

almost got it right: the program started back in the 1960s with EC-121Ds and was known then as Coronet Solo. Since a vanilla EC-121 was known as a Warning Star, presumably these would have been 'Radio Stars' (cue the Buggles)......

Jimmy Young isn't propaganda, he's psychological warfare, designed to cause the enemy to lose the will to live. If you broadcast him from a Coronet Solo plane you could revert back to it's civilian name and call it an EC-121 Consternation.
