KV5R: Icom IC-706MkIIG Mods and Tips

default. Set it to "On 2" and the 2 meter band will automatically set 

the right offset when you are in the range of the usual repeater bands 

-- 600 negative below 147, and 600 positive when above 147. This 

will save you a lot of extra offset-setting while you are programming 

your repeater channels. Also sets the usual +5.00 MHz offset for 440 

repeaters.

Item 24: AM NB: Set to "off" and the Noise Blanker will be disabled on 

AM reception, where it will otherwise cause distortion to strong AM 

signals.

Item 30: VSend Sel: Set to "off," the HSend line on the Acc’y jack will key the radio on all bands; Set to 

"on" (the default), HSend will key the radio on HF/6, while VSend will key it on V/UHF bands. "Off" is 

useful if you will key the radio from a computer interface for all bands. "On" is useful of you will key the 

radio with a computer on HF, but with an external TNC for V/UHF. You’ll need to study the book and do 

some fancy wiring on the 13-pin DIN plug...

To operate the computer digital modes, see the 

interface

 article, and for software and operating tips, 

see the 

digital-modes

 article.

The rest of the initial settings are usually OK -- by preference, or as-needed.

Now power off, and on, and go to the Q menu, by holding in the Display button.

Set the mike gain to 4-5: i.e., just where it changes from a 4 to a 5.

Notes:

1.  The supplied HM-103 hand mike contains a 1-inch broadcast-type condenser element designed by 

Bob Heil for Icon, and has excellent quality -- better than most HF radios. Never talk flat into the 

mike -- talk 

across

 it, about an inch away. This large-diaphragm mike element is too sensitive to 

use flat against the mouth. The HM-103 hand mike, and the Heil iCM series, are the only mikes 

you should use with a 706. Do 

not

 attach other mikes to the 706, or you will be disappointed!

2.  The mike gain setting is the same for all bands and modes Mike settings are NOT stored by band, 

modes, nor memory channel.
