KV5R: Icom IC-706MkIIG Mods and Tips

It is useful for:

1.  Accessing the new Amateur 60-meter channels

2.  Authorized MARS and/or CAP operation

3.  Authorized Maritime and/or Aviation SSB operation

4.  Authorized VHF and UHF public service (police, fire, etc) operation

5.  Authorized Land Mobile radio operation

6.  Authorized VHF marine operation

7.  Unauthorized operation on any frequency, only in immanent life/death emergency, only when no 

other means of communication are possible (legal but still legally risky)

8.  NOTE: Amateur Radios are NOT FCC TYPE-ACCEPTED to operate in other services — even if you 

have the license to do so! Don’t goof around in the legal gray area unless your leg is mashed 

under an 11-ton boulder! Remember that other (non-Amateur) radio services require not only a 

license, but also a radio that is FCC Type Accepted for that service!

Tools:

 The 706 uses components that are extremely tiny. You will need at least the following tools:

1.  2.5x to 3.5x headband visor magnifier or jeweler’s loupe

2.  Bright light

3.  15 watt pencil iron with a clean, lightly tinned, needle sharp point

4.  Fine-point tweezers

5.  Extremely steady hand

How to remove it (D2030):

(IC-706MkIIG ONLY - Top PCB - Red Arrow Indicates tiny SMT Diode to Remove.)

1.  Some people just crush it with needle-nose. I don’t like that idea since it might damage the PCB.

2.  Take the tip out of your 15-watt iron. Chuck it in a drill. Turn it against a grinding stone, to a 

needle point.

3.  Reinstall the tip. Heat and re-tin it. Tap off the excess solder.
