The transmission mode capabilities of WWII US military aircraft radios designed for general HF communication use had three modes in common - voice, MCW, and CW. I just finished reviewing the following maintenance manuals and found this to be well documented, not only in the obligatory beginning paragraph in each manual, but sprinkled throughout the manuals where necessary to provide circuit understanding and maintenance instructions: Navy RU/GF with early exceptions, GO-*, GP-*, ATA, ATB, ATC, ATD, AN/ARC-2, AN/ARC-5;  Navy/USAAF/USAF AN/ART-13, AN/ART-13A, and AN/ART-13B, USAAC/AAF SCR-183 and SCR-283 with early exceptions, SCR-274N, BC-375, etc. One can debate the specific aircraft in which one mode or another was used in greater amount, but documentation is hard to come by in that regard, and without solid references, it only counts as opinion and speculation. One has to consider the entire sweep of the war to properly assess the changes associated with such usage, both in the Pacific and in Europe. That covers a wide swath of time and dozens of different types of aircraft which came into and went out of the combat inventory of all U.S. Services, or it is an incomplete picture. The specific change to the ARC-5 page was made to set the record straight from the horse's mouth - the several manuals issued at different times for the AN/ARC-5. It is only by referencing written history that we can avoid the not-so-well caveated speculation that seems to characterize the world today.
