Radio Set TRC-20 is a low power, short range, FM (voice), transmitting and receiving equipment. It is used as part of a sound ranging system to detect low-frequency artillery reports or shell explosions in the field, and to relay this information to a central location for plotting purposes.
In operation, there were three remote units connected to transducers sitting on or buried in the ground. A fourth unit was the central receiver, and included a recorder from whose output the fall of shells was analyzed.Frequency range: 27.0 - 38.9 MHz.
