<div style="word-wrap:break-word;line-break:after-white-space">Initial impression about the Featherweight GPS Tracker is the boot process and connection over bluetooth
<i><b>just works</b></i>. Unlike the Missileworks RTx gear which is just downright fidgety and a PITA. And, I got two trackers that can both talk to the ground station at the same time, and be observed on the iPhone. That might be
cool for tracking multi-stage rockets, or having two rockets prepped the day before.

I just found out that the FCC opened (in 2017) GMRS (like family band on steroids) to short duration digital transmissions such as GPS data coordinate xmmission.. which could be huge for rocketry (multi-mile range).. if they ever get around to dropping the
meaningless license requirement:</div>
