TM 9-2350-275-BD COMMUNICATIONS SYSTEM 11-23. RADIO SYSTEMS FIELD EXPEDIENT General Information There are no known methods of constructing a field expedient radio. It should be noted, however, that hand signals, signal flags, flashlights, telephones, and messengers can be used in place of a radio. Communications can be restored by substituting optional equipment identified below. It should also be noted that if the intercom is not fully operational and the radio is operational but will not work with the intercom, radio communications can be partially restored by connecting the CVC helmet or an H-189 handset directly to the radio. Further, if the receiver transmitter is damaged, the auxiliary receiver can be tuned to the proper frequency and used for reception only. Limitations: ● Depending on extent of equipment damage or failure, partial to total loss of radio communications. Personnel/Time Required: ● 1 soldier ● 30 minutes Materials/Tools: ● Cable, telephone, WD-1/TT ● Field Telephone TA-312/PT, or TA-l/PT ● Flag set Procedural Steps: 1. Substitute radio with: a.

Power and signal cables are routed in and out of the mount through cables and plugs and in turn with a plug and jack method to the radio. If any of those plugs and jacks are damaged, the only feasible alternative is to replace the mount. Limitations: ● None Personnel/Time Required: ● 1 soldier ● 45 minutes 11-26
