The URC-200 (V2) VHF/UHF Transceiver is a lightweight, tactical, Line-Of-Sight
(LOS) transceiver that provides AM and FM communication of nonsecure voice or data.
The UVU-100 Radio Antenna is a ManPack antenna for backpack configuration,
weighing approximately one pound, and supporting frequencies of 115 to 174 MHz in
VHF band, and 225 to 400 MHz in UHF Band.
The PTHS-110 Handset is a PTT controlled handset that connects to the transceiver via
the front panel audio port.
The UAD-100A Uninterruptable Power Supply is made for “jerk-and-run” applications,
and operates from a 110/220-VAC source but includes two batteries which power the
radio when disconnected from the source.
The transceiver may be powered either directly by the batteries in the UAD-100A, or by
an AC source connected to the power supply. When the user keys the transceiver to
transmit by pressing the PTT button on the handset, audio from the handset is sent into
the transceiver through the Audio connector on the front panel. The audio is then
converted into an RF signal, and transmitted out the antenna connected to the RF I/O port
of the transceiver. When not keyed, the transceiver receives RF signals through the
antenna, and converts the signals back into voice heard by the user listening through the
handset.
