CHIRP

It maybe more than repeater splits that don't work, however, this is the easiest to test.

Start Chirp
Connect to IC92
Wait for the memories to sync
Go to Band B
It shows the value as 0.0000 for location 0 - (it is actually 5.0000)
Edit it the value to 5.0000
The status message shows it change
I can recreate this every time.

Bottom end of the log:

User selected Icom IC-91/92AD on port COM4
