Transmit Power

VHF Radio: 10 to 50 watts (programmable range)

UHF Radio: 5 to 50 watts (programmable range)

700/800 MHz Radio, 700 MHz Band 0.3 to 35 watts (programmable range); see

NOTE below.

700/800 MHz Radio, 800 MHz Band 1 to 35 watts (programmable range)

The 700/800 MHz XG-25M radio is aligned for a maximum transmit power of 35 watts

across the entire 700/800 MHz frequency band. However, FCC licensed systems, verify

the radio’s 700 MHz channels are limited to 30 Watts or per license requirements via the

radio’s personality programming.

The UHF XG-25M

radio is aligned for a maximum transmit power of 50 watts across its

entire 378 - 470 MHz operating band. However, f

or equipment operating in accordance

with FCC 47CFR80 rules (i.e., Maritime Services), it is the responsibility of the licensee to

ensure the radio is installed and aligned per license requirements.

Antenna Port Impedance: 50 ohms

Channel Spacing: 12.5 kHz or 25 kHz (mode dependent)

Voice and Data Communications Modes: Half-Duplex

Frequency Stability:

VHF Radio: ±2 ppm

UHF and 700/800 MHz Radios: ±1.5 ppm

Receiver Sensitivity

VHF and UHF Radios

Analog Mode: better than -119 dBm (0.25 µV) at 12 dBm SINAD

P25 Mode (TIA-102 Method): better than -116 dBm (0.35 µV) at 5% static BER

700/800 MHz Radio

Analog Mode, 700 MHz Band: better than -116 dBm (0.35 µV) at 12 dBm SINAD

Analog Mode, 800 MHz Band: better than -119 dBm (0.25 µV) at 12 dBm SINAD

P25 Mode (TIA-102 Method): better than -116 dBm (0.35 µV) at 5% static BER

Audio Frequency Response: 300 to 3000 Hz (transmit and receive)

Microphone Input Sensitivity: 82 ±28 mV rms (typical)

VHF radio is compliant with applicable FCC narrowbanding mandate below 512 MHz.
