[ARC5] SCR-274-N Freq Ranges in Use

[Robert Eleazer]

I found the reference, dated Nov 1942 which says that for "fighters converted to ground support airplanes at modification centers:  SCR-274-N, BC-696 required, BC-457A required, and BC-458A desirable but if it cannot be installed crate and ship or carry as loose equipment in plane."

Now, I am unaware of any three transmitter installations in USAAF fighter aircraft, but I assume they wanted the BC-696 2 to 3 MHZ transmitter for use for comm with the ground for fighters converted to ground attack, while retaining the more usual BC-457A and BC-458A transmitters if possible.. 

As for which fighters were fitted for ground support, all USAAF fighters did ground support, one way or another, at one time or another.  Perhaps they mean the aircraft such as the P-39's and P-51A's converted for tactical recon?

I also have a book that mentions the use of the P-51A in ground support due to its HF comm radios.
