Tom,
You need one CT-17 or equivalent level converter. I use the West Mountain Radio RIGtalk which is a USB serial port to CI-V interface. Many people build their own (easy for an RS-232 serial port) or buy inexpensive converters from ebay.
The CI-V interface is an "open-collector" party-line. You can parallel 2-4 Icom radios using Y-adapters, then connect it to the CI-V output of the CT-17, RIGtalk, or other similar interface.
Does that answer your question?

Eric,
Thanks for you input. I do have an additional question…... about the need of CT-17 level converter as noted in the owners manual, but I think Mike will answer it when he replies. This, to me, is the last piece of the puzzle (and my confusion). Is the ‘Y' adaptor cable to be used ‘in conjunction’ with the CI-V level converter or…..’in place of ' the CI-V level converter?
Again, I’m really impressed with the helpful responses I’ve received from this group, thank you. I feel like I’m almost there ;0)
73 Tom ps; from the looks of the archives, you have been involved in helping others for a long time !!

Tom, as Paul wrote already change the Icom address of one of the IC-706MKIIGs and enter the two addresses in the "Radio 1" section of menu "Radio Setup".
You can connect both radios to a single Icom CAT cable by using an Y-adapter on the radio side of the CAT cable. Make sure that the CAT cable works on Windows 7 and 8, see the reply of Mike, W4UOO.
When the program starts the radio with the first of the two addresses will run as the RX. In menu "Radio Setup" check the option "Autom. RX/TX Change". The program will then automatically change the roles of both radios as RX and TX. when you switch between u/v and v/u sats and you don't need to switch the 2m/70cm antennas between the radios.
Leave option "Satellite mode" and all other options in the menu un-checked.

Hello to the group……..
Does anyone have the specifics on how to setup two IC706 MKII-G’s for satellite ssb/cw operation (duplex).
I’ve done a bit of browsing and read the manual but remain confused on the hardware needed when using my Compaq laptop (no serial port), only USB’s.
Any advise would be appreciated.
