You're looking at $1200+ for the first year and then $400+ per year after
that. With APRS, you'll have a $300-400 up front cost with no charges
after that. But as I wrote, you have to have a HAM license too.

You just need a technician class license, for which you have to pass a
pretty simple multiple choice test. With APRS, your position would wind up
on an Internet site in close to real time.
