[NRVR-Members] GMRS Bands now open for short duration digital data and GPS coordinate xmissions

[Weeks, Thomas]

Was the Missleworks gear the one you had set up on your big black rocket with that blue 3D printed receiver?  I remember it not syncing up... was that the one you're saying was fidgety?


Jordan has used the featherweight quite a bit over the years.. and used hist 2m HT to receive the GPS data and graph it on google earth, iirc. It will be interesting to compare Missleworks, Featherweight, and EggTracker side by side.

Initial impression about the Featherweight GPS Tracker is the boot process and connection over bluetooth just works.    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.

Oh, that's a cool set of hardware (as long as you're on iOS). The flight computers are awesome.

Tweeks, I don’t know anything about rule changes, but I did get some new kit today.

Featherweight GPS Tracker and Ground
Station (iOS compatible, YAY!).   Operates on user selectable freq in the 900 MHz band.

Raven 4 altimeter and 38mm avionics bay with magnetic switch (magnet is the little black pill).

I need to test all available equipment so I can properly advise VT Rocketry teams.  ;-).  Already looks nicer than Missileworks but proof is experience on the flying field.

Hey radio geeks..



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:
https://www.fcc.gov/general-mobile-radio-service-gmrs



I have also heard rumor that 900MHz ISM band (currently used by EggTimer, etc) might be "going away" for unlicensed use (as we are using it)..



Anyone else know more?



Is Bob McGuire back on here yet?
