Kenwood NX Series AutoTune™ User Guide

1. Introduction

The Freedom Communication Technologies R8000 Series Communications System

Analyzer AutoTune™ (hereafter “AutoTune”) is designed to provide an automated test

and alignment solution for supported two-way radios.

2. Scope

This document is intended to provide information regarding the tests and alignments

performed for supported radios by AutoTune. This document is restricted to radio-

specific information for Kenwood NX Portable and NX Mobile radios.

Please refer to the R8000 Series Communications System Analyzer Owner’s Manual

(CG-1365) for an overview and basic operating instructions for AutoTune itself.

3. Conventions

Rated Audio. Approx. 630 mVrms for Kenwood NX Portable and 2.83 Vrms for

Kenwood NX Mobile radios across a 4 Ωspeaker.

Kenwood NX Series AutoTune™ User Guide

4. Kenwood NX Portable Radio Test Setup

In order to perform the test and alignment procedures, the NX Portable radio must be

connected to the R8000 Communications System Analyzer as shown in the figure

below.

Make certain that the radio under test is configured as described in the

corresponding diagram before attempting to perform an alignment or test.

Failure to do so may result in poor radio performance and/or damage to the

analyzer or radio equipment under test.

4.1. NX Portable Test Setup

Refer to the diagram below for the proper test setup. Note that the correct setting for

each test set switch is listed in TEST SET SETTINGS.

Note: Approved USB to serial adapters for connecting the R8000 analyzer to the

Kenwood NX series radio under test include any adapters which utilize an FTDI

FT232_USB to serial UART interface OR Prolific Technology Inc. PL-2303 USB to serial

controller interface. See http://www.ftdichip.com/Products/ICs/FT232R.htm or

http://www.prolific.com.tw/US/ShowProduct.aspx?pcid=41 for more detail.

5. Kenwood NX Portable Alignment and Test Descriptions

Note: Throughout this section are references to Test Frequency. Test Frequencies are

band- and mode -specific. A table of the frequencies used by each band may be found

in the respective radio service manual.

Note: All analyzer Mode settings are Standard unless otherwise indicated.

5.1. Assist Voltage

5.1.1. Alignment

The radio is placed into Test Mode and its VCO lock voltage is adjusted at several RX

and TX Test Frequency points. The new softpot values for the voltages are then

programmed into the radio.
