The SCR-694 provides transmission and reception of AM radiotelephony and MCW or CW radiotelegraphy within the frequency range of 3.800 to 6.500 MHz.
The radio set consists of the BC-1306 receiver and transmitter along with ancillary equipment, not all of which was required in every signal mission.
The SCR-694 began to replace the SCR-284 from mid 1944,[1] with improved range and reduced weight (around half of its predecessor), though the latter continued to be used up until the end of the war.
Designed to provide communication between moving or stationary vehicles or as a portable field radio set, the SCR-694 was originally intended for use by mountain troops and airborne forces but soon became the Army-wide standard at battalion level.
The SCR-694 saw use all over the army in many different theaters; notable instances include at regimental division headquarters during the Normandy invasion[2] and the Cabanatuan prison raid[3] as well as by scouts and reconnaissance units in the Pacific War.
