Introduction

Ah, the li’l 706: What can I say? I like it! It 

performs like big radio, but it’s small. It 

sounds good, and it’s well made. You can add 

the remote kit and put the control head and 

the radio box where ever you want them. The 

price is right.

This article is a handy compilation of most of 

the mods and stuff I have developed or found on the web for the 

706MkIIG, plus a chronicle of the little accessory kits that I have built 

to enhance my enjoyment of the 706.

Disclaimer:

 The author assumes absolutely no responsibility, under 

any circumstances, for what the reader may do with this information. 

Building and connecting circuits, and performing adjustments or 

modifications, may damage your radio, void your warranty, and/or 

cause it to operate in violation of FCC rules and Type Acceptance, etc, 

unless you are VERY CAREFUL.

Brand New 706 Setup

The 706 comes with several factory defaults that you'll want to 

change. The recommended changes make the radio easier to operate. 

First, let’s set up the power-on defaults.
