3 INTRODUCTION
This manual contains installation procedures for the M7300 mobile radio and the CH-721 control heads.
Procedures cover the mounting and cabling of the equipment, as well as the basic test procedures. In
addition, product safety-related information is included.
3.1 GENERAL DESCRIPTION
The M7300 mobile radio is a high-performance digital mobile radio. Shown in Figure 5-3 on page 28, the
M7300 mobile radio is available in both a VHF-band-only radio and a dual-band 700 and 800 MHz radio.
3.1.1 VHF-Band M7300 Radio
The VHF-band M7300 radio can operate in the 136 to 174 MHz RF band with the following radio
systems/standards:

APCO Project 25 Phase I compliant Common Air Interface (P25 CAI) trunked radio networks;

Talk-around communications in accordance with the APCO Project 25 Phase I standard; and,

Conventional FM repeater-based and FM talk-around voice communications in VHF-band in
accordance with the TIA/EIA-603 conventional land-mobile radio standard.
3.1.2 Dual-Band 700 and 800 MHz M7300 Radio
The dual-band 700 and 800 MHz M7300 mobile radio can operate with the following radio systems/-
standards:

700 MHz and 800 MHz OpenSky
®
trunked radio networks using the OpenSky Trunking Protocol
(OTP);

800 MHz Enhanced Digital Access Communications System (EDACS
®
) trunked radio networks;

800 MHz ProVoice
™
trunked radio networks;

800 MHz APCO Project 25 Phase I compliant Common Air Interface (P25 CAI) trunked radio
networks;

700 MHz talk-around communications in accordance with the APCO Project 25 Phase I standard;
and,

Conventional FM repeater-based and FM talk-around voice communications in 700 and 800 MHz
bands in accordance with the TIA/EIA-603 conventional land-mobile radio standard.
700 MHz operating bands of the dual-band M7300 mobile radio include the repeater output bands
(mobile receive) of 764 to 767 MHz, 769 to 775 MHz and 773 to 776 MHz, and the repeater input bands
(mobile transmit) of 794 to 797 MHz, 799 to 805 MHz and 803 to 806 MHz. The radio also provides
talk-around operation in the 764 to 767 MHz, 769 to 775 MHz and 773 to 776 MHz bands. In high-power
transmit mode on a 700 MHz RF channel, the radio’s rated transmit output power is 19 watts.
800 MHz operating bands of the dual-band M7300 mobile radio include 806 to 824 MHz repeater input
band (mobile transmit) and the 851 to 869 MHz band used for repeater output and talk-around
communications. In high-power transmit mode on an 800 MHz RF channel, the radio’s rated transmit
output power is 35 watts.
3.1.3 General Information
The M7300 is designed to operate in a mobile environment, typically within a motor vehicle. It must be
connected to an external transmit/receive antenna such as one mounted to the vehicle’s rooftop or trunk
