1.0 INTRODUCTION
This manual provides operation and maintenance instructions for the URC-200 (V2) Radio Set, part
number 01-P36744M003, shown in Figure 1. The radio set is a lightweight VHF/UHF transceiver
providing AM/FM transmission and reception of non-secure voice or data in the frequency bands
used in maritime, land, mobile and tactical line-of sight communications, as well as military and
civilian air traffic control operations. Secure communications are achieved with an appropriate
external encryption device and with the transceiver in the data (Cipher Text) mode.
NOTE
The URC-200 (V2) is FCC certified in the 115 – 149.995 (AM) and 115 –
173.995 (FM) bands.
1. The URC-200 (V2) transceiver is to be tuned only to those frequencies
that the transceiver user, by law, is permitted to use.
2. Operation and tuning the transceiver should be restricted to those users
who are knowledgeable about which frequencies are authorized for use.
3. Transceiver operation on unauthorized frequencies is a violation of the
law.
4. The capabilities of this transceiver allow users the freedom for authorized
personnel to easily tune the transceiver. This allows the transceiver to work
with other communication systems within the band, if the transceiver's tuned
frequencies are permitted by regulation.
1.1 Purpose and Functions
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. It is suitable for
ManPack, vehicular, or fixed station applications. The transceiver is compatible with other AM or
FM transceivers operating in the same VHF and UHF frequency ranges.
• In the AM mode the VHF frequency range is 115 to 149.9950 MHz
• In the FM mode the VHF frequency range is 115 to 173.9950 MHz
• In both the AM and FM modes the UHF frequency range is 225 to 399.9950 MHz
The transceiver has standard tuning increments of 25 kHz, 12.5 kHz and 5 kHz with a channel
spacing as detailed in Table 1. The transceiver is capable of transmitting and receiving analog Plain
Text (PT) voice and digital Cipher Text (CT) voice or data. Achieve secure communications with
an appropriate external encryption device and the transceiver in the data (CT) mode. The URC-200
(V2) operates in most weather conditions and can be remote controlled.
