[chirp_users] Icom IC-746Pro
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...

You can't change the CI-V address in CHIRP, you'll have to set it in the radio. The CHIRP driver expects the 746 to be at address 56, so I would give that a try.

Thanks, Dan. That didn't work either. You mean 56h (hex) or 0x56, right?
When downloading from the radio, the channel numbers appear highlighted in red with an exclamation point ahead of each one, presumably denoting an error. Nothing appears in the rest of the spreadsheet.
I did notice that the error indications showed up a lot faster when the address is set to 0x56 than when set at 0x66, so at least there is some indication that changing the address had some effect.

The driver is marked as "746" not "746Pro" so it's very possible it won't work for your model (I didn't write the driver so I'm not positive). The presence of this bug indicates that's the case:
https://chirp.danplanet.com/issues/2157
If the memory format changed at all between the two (which would not be unusual) then it won't work and the behavior would match what you describe. Effectively "I got a response but it was not what I expected, so error" when the address is right and "I never got a response" when it's wrong.
You're welcome to add your debug log to the bug above, which will give some hints for someone who might come along and want to implement the 746Pro. See:

I see a discrepancy between the 746 and the 746PRO in the "OK" and "NG" reply message from the radio back to the computer.
746: FE FE 56 E0 FB FD
746PRO: FE FE E0 56 FB FD
The "56" (the radio's address) and the "E0" (the controller's address) are reversed between the 746 and 746PRO. Why in the world would they do that??
I suppose that could be a misprint in the Icom user's manual (one or the other) although that seems unlikely. Anyway that would account for the errors I'm seeing.

All the Icom (not just the CI-V) radios we support use the same low-level transport, which means none of them have transposed addresses. I can't imagine the 746Pro is an oddball in this regard, so I imagine it's a misprint.
Anyway that would account for the errors I'm seeing.
I don't think it would, but again, without seeing the debug log, it's hard to say. The issue tracker is the right place to do that, not on this users' list with 2000+ people subscribed.
Thanks!

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.
