Featherweight GPS uses the 900 MHz (902-928) band and so there is no HAM
license required.
16 K’ and 2 miles with the Eggfinder is pretty good!
I have compared the Eggfinder and FW on the same flight and the FW had a lot
more tracking points. A cool thing using MapSphere with the Eggfinder is that
you can see the track real time using an aerial image layer. On the other
hand, the FW app is easy to use and has audible call-outs during the flight so
you can focus on watching your rocket, not a screen. The wireless connection
on the Eggfinder has been inconsistent so I would suggest using a USB
connection to a laptop for the Eggfinder.

I like the Eggtimer stuff myself. You need to solder, but it is the most
economical and it does work well for me. Have gone to 16,000 ft and 2 miles,
on recovery. I do know Bdale of Altus Metrum very well and can tell you it
works and is very well engineered. Also am acquainted with Adrian Adamson of
Featherweight and can say that that is also very well engineered. I like the
connectivity of Featherweight. and the distances that both Featherweight and
Altus Metrum transmit. I know that Altus Metrum requires a Ham license but
that is not a big deal. Not sure about a license with Featherweight.

Chris,
Eggtimer has a suite of products that don't require ham licensing. They will
cover any altitudes at Lucerne, and in many cases will cover most flying
people will do just about anywhere really. They do require assembly and use
surface mount components. Many people find with a little practice they can
manage, and even enjoy it. There are also people that will assemble them for
you. One plus is the manufacturer attends many launches, so you can get field
support -- well, if he's not out recovering his rocket :-)
