335:. This included an updated XCJ-2 system from NRL (produced as the TX), the modified airborne AN/ARQ-8 Dinamate system from Harvard's Radio Research Laboratory, NRL's improved XCJ-3 model (produced as the CXGE), the Types MAS system produced by the Airborne Instruments Laboratory (at the time affiliated with the Radio Research laboratory), the British Type 651, and the Canadian Naval Jammer.
366:. It could easily be swapped in place against the radio system. In the plane radio transmitter S203 was swapped against the audio amplifier S207. In the weapon, VHF receiver E230 was replaced by audio receiver E237. Both plane and bomb were equipped with a dual wire reel each, giving a maximum distance of 12 km. Wire remote control system was developed by Staßfurter Rundfunk GmbH

In contrast to the experience at Anzio, jammers seemed to have had a major impact on operations after April 1944, with significant degradation observed in the probability that a Hs 293 launched at a target (and responding to operator guidance) would achieve a hit or damage-causing near miss.
349:
Even more sophisticated jammers from NRL, designated XCK (to be produced as TY and designated TEA when combined with the upgraded XCJ-4) and XCL, were under development but were never deployed as the threat had evaporated before they could be put into service.
296:. These six ships rotated service at Anzio, with three deployed at any time. The manually operated jamming system met with some success, though it proved cumbersome and was easily overwhelmed if large numbers of weapons were deployed simultaneously.

command frequencies were in use and then manually tune the jamming transmitter to one of them. The Type 650 automatically defeated the receiver, regardless which radio frequency had been selected for an individual missile, be it Fritz X or Hs 293.
