I know that I still have my stock mic, but off the top of my head, I don't know where I stuck it, lol.
You could swing by a truck stop, though, and pick up a cheap mic for testing purposes. Or, pick up a nicer one to keep on hand as a backup; spare parts and accessories are always good to keep around, anyway. Or, if you have a friend nearby, who also has a CB, you might see about borrowing a mic from him for about 5 minutes.
I have no experience with the Extreme 2018, and know very little about it. It could be that you have a factory defect in that mic. Is it noise canceling? Maybe whatever cancels the background noise is defective. Maybe there is a short in one of your settings dials, and the mic thinks that it's set all the way up to 11.
Or, it could just be what Sonoma said; talkback and that mic just don't play nice together.
I don't really know why the 980 NEEDS talkback. Keeping it on has never appealed much to me; it's very distracting to me, to hear myself as I speak. Hard to complete a sentence, without losing my train of thought. Even if I had echoing capabilities, I wouldn't need to use talkback to check it, because I wouldn't use that, either.
I guess I've just gotten boring as time progresses, lol.
