Green Palm, a VHF noise jammer, only worked on 4 preset frequencies and was very limited, although it might have upset nearby TV reception. But TVs of those days would be upset by pretty well any nearby RF source...
Green Palm was removed, Blue Diver and Red Shrimp were simple radar jammers which weren't very advanced - and ARI 18146 was a real Sparrow magnet for HOJ or RSOJ attacks by any competent F-4 crew, so the opposition were probably equally capable of such an attack.
Of course this antique junk should have been upgraded to keep up with the threat as the Vulcan's in-service life pushed to the right. As was the B-52's equipment. But it wasn't; for EX GIANT VOICE 1979, the USAF had to drag something out of a museum for us to be able to jam during the competition and in 1982, 'Dash-10' pods had to be fitted to give any worthwhile protection against Argentine AAA for the attacks against Stanley aerodrome.
The myth of a Vulcan being successfully able to jam its way to the target should be dispelled - after the late 1960s Vulcan ECM was virtually obsolete. Although we had to be able to recognise and trot out facts about various radars, fighters etc., there was no proper tactics training. For example, we didn't even know that a fighter AI radar doesn't need to lock on to the target for a successful attack.... Neither did we know anything about lead/lag angles, off-boresight shots, beam look-up shots etc.
