[Milsurplus] TBS question

George, Bill, Hue, et al,

The aircraft sets started off using the same two-letter sequences as the 
ground/shipboard sets (GF, GP, RU, etc.) but then went to three-letter beginning 
with ATA, ARA.  It doesn't look like the DF receivers were differentiated any 
more (would have started with ADA).

First DF receiver was DA, 250-600 KC, 1918.
