This document is a salient characteristics specification sheet for the URC-300 VHF/UHF Transceiver, a single-unit radio system intended for operational use.

The URC-300 is a rugged, portable VHF/UHF transceiver weighing 10.9 pounds with dimensions of 11.1" L x 8.4" W x 3.4" H. The unit is environmentally tested for humidity, vibration, shock/drop, rain/drip-proof conditions, and temperature extremes (-25°C to +55°C operating; -40°C to +70°C non-operating), complying with MIL-STD-810H and rated IP65 for ingress protection. Power options include a rechargeable BB-2590 battery, AC input (108–253 VAC, 47–63 Hz), and DC input (10.7–34 VDC). Current consumption at +28 VDC is less than 3.5 amps during transmission and less than 0.8 amps during reception. The frequency range spans LVF (30 MHz to 90 MHz FM), VHF (115–150 MHz AM/FM), and UHF (225–399.995 MHz AM/FM) with 25 kHz, 12.5 kHz, 5 kHz, and 8.33 kHz tuning increments compliant with ETSI EN 300 676-1 standards. The transceiver features 20 independently programmable channel presets with frequency stability of ±1 PPM and supports both AM and FM modulation. Receiver sensitivity achieves -103 dBm for AM voice and -114 dBm for FM voice, with a dynamic range of 118 dB and cross-modulation rejection of at least 80 dB. Transmitter output power ranges from 1 to 7 watts (AM) and 1 to 10 watts (FM), with optional 50-watt tri-band power amplifier capability.
