Hi Dave, > Can anyone authoritatively tell me when the German armor >began using 20-30 MC for their comm? >I've been told this was late-war, In the same book I mentioned earlier, there is a table of each VHF model set and when it was first introduced. The UkW.E.a (listed as 25-29 and 29-33 MHz) was introduced in 1935. I can scan and send you the table if you want. Tom
