  The Special Services (morale) Division of the US Army requested the radio from Hallicrafters with unique requirements such as flame-proof wire insulation, recessed knobs, moisture and fungus proofing, and use of generic 4.5 and 45 volt batteries with screw terminals. The set was named as an alternative to the later Signal Corps-designed R-100/URR made by a number of manufacturers.  Batteries were two 45 volt units in series, and four 4.5 volt units in series-parallel.

  Both sets were named in memos written by the Headquarters, European Theater of Operations in October 1944 and March 1945 detailing their distribution with the RE-1 named by the Army as a suitable substitute for the R-100. The radios were to be provided on the basis of one per fifty men and to each isolated unit of less than 50 men. The R-100 or RE-1, each having battery capability, were a priority for organizations that did not have access to external power. The radios were not to be issued for personal use, officer clubs, or recreational rooms until all enlisted men had adequate supply, "By Command of General Eisenhower".

  When operated on AC/DC, four of the battery tube filaments were powered by the cathode bias on the 50L6 audio tube. 

  The development of the RE-1 is described in an article in the May 1945 Radio News.
