The radio frequency RF sensitivity studies are continuing. RF systems for firing the Mk 2 Mod 0 ignition element and the Mk 1 Mod 0 squib are discussed. Emphasis is on theoretical means for matching at 5 and 30 mc. Some specific details of practical systems are given. The adaption of the Mk 2 firing mount to accommodate the Mk 1 squib is described. A unique adjustable shorted stub was completed and utilized for firing at 250 mc. A method for the determination of system loss factor is presented. The systems for firing the Mk 1 squib and the Mk 2 ignition element were calibrated to obtain these losses at frequencies of 5, 30, and 250 mc. Bruceton tests were conducted with both the squib and ignition element at 5, 30, and 250 mc.
