I’ve had one of these for about five years now, what’s not to love.  I’ve taken this rig to all the New England states, hiking on the Appalachian trail and had a blast maritime mobile.

A lot of people don’t know how truly flexible this radio is with a few mods or hours on the bench making your own accessories.  Whether you homebrew your own CI-V interface (rig control) or mic mods, there’s so much there to do.

I stumbled on a page that had some detailed info recently and decided to rumble through my bookmarks and post a bunch of the mods here.

There are hundreds of sites out there on this rig, so if you know of a good site with mods and such, post in the comments section and share with everyone else!

Athens (TX) ARC has a neat page to get you started at:

DF4OR has a great site devoted to the CI-V interface with loads of info and projects at

Hampedia has a bunch of links and text files devoted to many projects at has a nice list at

KB2LJJ has a bunch of info (though the links are hard to read with the color in the background) but the info is useful indeed:

Probably one of the most useful resources is on the RigPix database – the service manual!

As usual, if you have any good links, comment below.

8.30.09 addition:  I found this site to have LOADS of 706 information:

I’m often struck by the quality of freely available software.  I’m a huge proponent of open source software.  However, software doesn’t have to be open source to be monetarily free.  Ham Radio Deluxe is such a program.

Let’s take a deeper look at why I’ve recommended this software so often over the past few years.

This software does so much more than just control your rig.  It is a full featured software package that also includes:

  • full featured logbook
  • dx cluster (customizable)
  • log book analysis
  • satellite tracking interface
  • scanning
  • and a whole lot more

You can connect this software to your radio using a normal serial port and several possible interfaces.  I currently use a West Mountain Radio Rigtalk. The radio I use is a 706 MKIIG.

You can get that interface rather cheap (around $60.00).  You can also homebrew interfaces really cheap, but then you will still need a USB to serial interface if you don’t have a serial port on your computer.  I use a laptop that doesn’t have a serial port, so the cost of sixty bucks was a reasonable one.

Here are some screen shots of several of the other features:

There’s a lot more to the software.  You can spend easily a hundred dollars or so to perform the same tasks as you can with HRD for free.

As mentioned before, if you don’t have a USB-serial converter and the additinal hardware, you can pick up the West Mountain Radio RigTalk as shown below at their website West Mountain Radio RigTalk
