Hi @K8KCI we would love to have your help on testing! You can get a great start by using the “Report a Bug” and letting us know what issues/bugs you are able to find - we appreciate any bug reports there.
The call Sign issue is know - we need to enhance our database to add more international call signs.
I am not able to reproduce the issue with the header on the logging page. Could you provide some more details or perhaps try to take a screenshot or loom video?
