GENERAL
PRE-INSTALLATION CONSIDERATIONS
1. UNPACKING
Unpack the radio from its shipping container and check
for accessory items. If any item is missing, please contact
KENWOOD immediately.
2. PRE-INSTALLATION CHECKOUT
2-1. Introduction
Each radio is adjusted and tested before shipment. How-
ever, it is recommended that receiver and transmitter opera-
tion be checked for proper operation before installation.
2-2. Testing
The radio should be tested complete with all cabling and
accessories as they will be connected in the final installa-
tion. Transmitter frequency, deviation, and power output
should be checked, as should receiver sensitivity, squelch
operation, and audio output. Signaling equipment operation
should be verified.
3. PLANNING THE INSTALLATION
3-1. General
Inspect the vehicle and determine how and where the
radio antenna and accessories will be mounted.
Plan cable runs for protection against pinching or crush-
ing wiring, and radio installation to prevent overheating.
3-2. Antenna
The favored location for an antenna is in the center of a
large, flat conductive area, usually at the roof center. The
trunk lid is preferred, bond the trunk lid and vehicle chassis
using ground straps to ensure the lid is at chassis ground.

3-3. Radio
The universal mount bracket allows the radio to be
mounted in a variety of ways. Be sure the mounting surface
is adequate to support the radio’s weight. Allow sufficient
space around the radio for air cooling. Position the radio
close enough to the vehicle operator to permit easy access
to the controls when driving.
3-4. DC Power and wiring
1. This radio may be installed in negative ground electrical
systems only. Reverse polarity will cause the cable fuse
to blow. Check the vehicle ground polarity before instal-
lation to prevent wasted time and effort.
2. Connect the positive power lead directly to the vehicle
battery positive terminal. Connecting the Positive lead
to any other positive voltage source in the vehicle is not
recommended.
3. Connect the ground lead directly to the battery negative
terminal.
4. The cable provided with the radio is sufficient to handle
the maximum radio current demand. If the cable must be
extended, be sure the additional wire is sufficient for the
current to be carried and length of the added lead.
4. INSTALLATION PLANNING – CONTROL STATIONS
4-1. Antenna system
Control station. The antenna system selection depends
on many factors and is beyond the scope of this manual.
Your KENWOOD dealer can help you select an antenna sys-
tem that will best serve your particular needs.
4-2. Radio location
Select a convenient location for your control station ra-
dio which is as close as practical to the antenna cable entry
point. Secondly, use your system’s power supply (which
supplies the voltage and current required for your system).
Make sure sufficient air can flow around the radio and pow-
er supply to allow adequate cooling.

1. Overview
NX-800H (K3) is a UHF Mobile transceiver designed to
operate in the frequency range of 380 to 400MHz (in user
mode). The unit consists of receiver, transmitter, phase-
locked loop (PLL) frequency synthesizer, base band parts,
power supply, and control circuits.
CIRCUIT DESCRIPTION
2. Frequency Configuration
The receiver is a double-conversion super heterodyne
using first intermediate frequency (IF) of 58.05MHz and
second IF of 450kHz. Incoming signals from the antenna
are mixed with the local signal from the PLL circuit to pro-
duce the first IF of 58.05MHz. This is then mixed with
the 57.6MHz second local oscillator output to produce the
450kHz second IF. The transmit signal frequency is gener-
ated by the PLL VCO, and modulated by the signal from the
DSP. It is then amplified and fed to the antenna.
