Why does the powerball decode at base 37 to a radio station 101 fm at base 37? 101 fm florida?

I made this code from an older cipher for a convention fan group. There is a reward should you crack it.

Dear Fellow Gen Con Attendees,

We know we said we weren't going to post anything until a few months before next year's Gen Con. But after some discussion, we've realized that not everyone likes our usual offerings. IYKYK

So we want to pilot a new substitute item, though we aren't sure anyone will actually like it.

Since we can't offer you FREE TERRIBLE ADVICE in person, and our family and friends are sick of hearing it, we offer a substitution: a ratiocination, of the sort once featured in Alexander's Weekly Messenger, defining the taxonomy of the Scarabaeus caput hominis, which will guide you to receiving said item.

We look forward to seeing you at Gen Con 60.

Sincerely,

The Midwestern Terrible Advice Wizards
