Equipment Description

The U.S. military has many Field Strength Meters. These are used for a number of purposes, but the key one is to tune up radios after they are configured on a new frequency. Ham radio operators use a VSWR meter, but that is not possible on many military radios since the antenna attaches directly to the radio, i.e. there is no place that in the antenna system that’s 50 Ohms.

The “PHONES” jack can by used to hear an AM version of the signal being received by the ME-61. This signal monitor function may be done at the transmitter location in cases where the transmit antenna is located some distance away to confirm that a signal is getting out.

The TM shows the GRC-9 being used to provide a test signal for the ME-61. But the AN/GRC-9 covers only 2 to 12.

The AN/GRC-19 (T-195 & R-392) convers 1.5 to 24 MHz matching the ME-61.
