[Milsurplus] Re: Beginning of use of UHF aero radios

Aw, shucks.  I completely forgot about the MAR (manual base date 04 May 
1944).  Manual that I have on RDR is dated 10 December 1945.  There may have been 
an earlier edition, maybe just an IB.  I don't have a TED manual.  Earliest 
manual I have is on TED-2 and it's 50's, but may be a major rev after numerous 
Field Changes as it has an A" suffix.  RDZ manual is dated 14 April 1945.  TDZ 
dated 13 September 1945, but I have an undated unnumbered Instruction Book that 
it probably earlier.

This is all shipboard end sets of course.
