I tested two radios on the Radio Shack USB Scanner cable to 2 ICOM radios
simultaneously. Works great !
If you Connect, from the 1/8" mono male plug to a 1/8" Female to 2 1/8"
Male Mono Y Cord to the *"Remote" *1/8" connection on each 706 radio as
shown on P.12 of 706MKIIG Manual (make sure that the 2" long Stereo to mono
adapter is in line).
Follow instructions to install drivers, don't plug in the USB cable to the
computer before the instructions say to plug it in, this can be a big
problem in some cases..
On the 706MKII G:
The goal here is to do 2 things,
1. To set the "CI-V addresses" on the 2 radios to 2 different addresses,
by default, they are set to the same address, which is probably 58H
1. Thus, you only need to change 1 radio, and confirm the setting on the
other radio so that you can set up SatPC32 accordingly.
2. To set the Baud Rate to 19,200 on both radios
3. Check 2 other settings, make sure they're at the defaults.
*Here we go, steps to get this done: (I verified on my 703, should be
*Go into the Setup Menu by doing the following: (This is from the 706
D Initial set mode operation
➀*Push [POWER] for 2 sec. to turn power OFF.*
➁*While pushing [LOCK] push [POWER]* to turn power
•Initial set mode is selected and one of its items appears.
(These items are on page 50-55)
*.....go to "Here's your needed Settings"*
➂*Push [MENU] one or more times to select the*
*desired item.* * This is how you "Scroll" through the settings*
•[M-CH] or [Y]/[Z] can also be used.
➃Rotate the main dial to set the values or conditions
for the selected item. *This is how you change the actual "Setting"*
*Once complete, hold down the Power button for 2 Seconds to power off, then
power back on.*
*Your *needed Settings
(These options are shown on Manual Page 55)
Scroll to Menu Option 34 by *Pushing the [MENU] one or more times* until
* 34 CI-V Address:*
You need to decide which Radio is considered #1 and which is #2
On Radio #1 set Menu Option 34 to: 58H (Rotate the Main Dial to
change if needed)
On Radio #2 set Menu Option 34 to: 50H (Rotate the Main Dial to
Keep these 2 settings handy, you'll need them when configuring
Scroll to Menu Option 35 by *Pushing the [MENU] one or more times* until
* 35 CI-V Baud:*
Set to 19200 on both Radios
Scroll to Menu Option 36 by *Pushing the [MENU] one or more times* until
* 36 CI-V Trn*
Set to On (Rotate the Main Dial to change if needed)
Scroll to Menu Option 37 by *Pushing the [MENU] one or more times* until
* 37 CI-V 735*
Set to Off (Rotate the Main Dial to change if needed)
Now the 2 radios should have the correct settings:
You can review the settings if you like, by scrolling through
them by Pushing the [MENU] one or more times, then when finished, hold down
the Power button for 2 Seconds to power off, then power back on.
Connect the USB adapter to the Computer (follow the instructions before you
plug in the USB adaptor), then configure the SATPC32 using the CI-V
addresses from above...on which ever Com Port the USB adapter is using
My suggested addresses:
58 for Radio 1
50 for Radio 2
Baud Rate: 19,200
Com Port Number will be the same for both radios because they use the same
USB interface. That is fine...
