I'm trying to find an expired call sign. If anyone has an old FCC
database, I'd appreciate someone looking up the call sign KU5588.

This call sign is accessing a local GMRS repeater. I assume the
person's license is expired. If so, they no longer have GMRS operating
priveleges and need reported to the FCC for violations.

Even if you located information on who was licensed as KU5588, that
doesn't mean they couldn't have sold the equipment to someone else. It
could have easily passed through several hands by now.

Expect to be underwhelmed with an FCC response.

My suggestion would be to change PL or possibly to DPL.
