>Also the question was asked about the max range of the SCR-522 on VHF.

Many of the WWII airborne VHF set operating instruction manuals contain a graph of line-of-sight miles vs. aircraft altitude, and that range was pretty much independent of the power output of the transmitters.  The graph that's in the manual for the AN/ARC-4 (AN 08-10-245), for example, gives the following:

Altitude (ft)     VHF LOS Range (Statute Miles)

  1000                  40
10000                 115
30000                 210
