Rondar and Smokingloon,
That kind of communication did not exist, and largely does not exist now. Marking their positions? Do that and the enemy can spot you too. Wirbelwinds and the like were not there to support their airforce, they are there for the protection of the army. Even if they, which they did not, had radio contact, what are they going to say? "Bf109, drag that Spitfire over here!" "Ah, Wirbelwind, where is "over here" exactly?" "Over by the big copse of trees, by the hill with the large oak." "Um, right."
Tank-Ace,
I am not one of the people who would go bomb GV fights unless they are being used to take an airfield. If I flew to a fight between GV fields it was to provide top cover for our tankers, killing the A-20s and Il-2s that were after them. The shoe is not on the other foot here, it is on a completely unrelated foot that previously had no part in the discussion.
