I have worked on maybe 5 CBs, a little Marine and did a Avionics project.
Most of my time was spent with cutting edge PLMR and SMR projects for
commercial, business, and Industrial customers. Most of those customers
have gone to the phone companies though.
I was successful with the Fire customers, but the LE bunch always wanted a
piece of the action. Hard to subsidize them when they are THE only action
left.
They may have automatically converted you. I too let it slide but they
converted and renewed it to lifetime anyway. You can look up your name (the
one that you used) in ULS and find out if you have an active license. They
seem to like to keep their database entries. I couldn't even throw mine
away.
Here's the search page to look yours up:
