How can you tell if the two IC’s for CAT operation on the above radio are installed or not w/o opening up the radio??? Thanks
The functional test would be one option, but if this is the first setup the chances are good that the test will fail for some other reason even with ICs installed because there are many variables.
The radio is between 30 and 40 years old. You will not be losing warranty by peeking under the hood:

That’s for sure ! I spent enough on it that I don’t want to cause more damage, lol
Thanks
