You don't have to take the test again. I believe you only have to take the test if your license expires at the end of the ten years AND you wait more than two years before renewing it again.

Thank you for your response.

I did get my novice license (or whatever the lowest license is called) but never got an old borrowed radio to actually transmit. Then life kind of got in the way.

I keep meaning to get back into it, the sstv and various data networks are really cool. I really dig the analog tech.

Yeah even if you move to another country you don't have to do the test again. You can just transfer your license.
