There used to be a very useful website that had all of the details for the different Icom CI-V radios, but it went offline a while ago (or at least the most useful portion of it did). I have a local copy, and it includes the following remark in relation to reading / writing memories:
"The data layout is specific to the IC-746. The IC-7400 (IC-746Pro) uses a different memory layout."
That means you won't be able to program the IC-746 Pro with Chirp until the CI-V driver is updated to add support for that radio.

Good afternoon all, from a new Chirp user.
Is there a difference between the Icom IC-746 and IC-746Pro in the way it communicates from the Remote port?
I downloaded and installed Chirp and tried to connect to my IC-746Pro using the Chirp IC-746 configuration, and could not connect.
Tried the same thing with my IC-7300 (using the Chirp IC-7300 configuration) and it connected and programmed the memories just fine, so the cable and the computer's USB port are working as they should.
I did verify that CI-V is turned on in the radio and the address is set to 0x66. (Speaking of which, how do I set the address in Chirp? Maybe that's the problem...)
Thanks...
