Does this only apply to the apx8000 when I change the value to the new value in my 8000xe the radio has a error that says no comms.

From the original post above:


Only applies to APX8000 and APX6000BN models

So since the 8000XE is not listed you should not need to change anything

You posted the original MTN. It has since been updated with a different value for the APX8000.

Since both 8k and 8kXE are APC 579, it applies to both of them.

 

[GTR8000]

The correct ISW value for the 8000 and 8000XE is FEA8

The 6000BN remains FEA0 as per the original bulletin

For all other APX models, the correct value is FE35
