[NRVR-Members] Tracking Beacon/System Reccomendations?

I've heard great things about the Egg Timer units.

I really want to get a 70cm APRS based tracker (like the cool stuff Jordan flies).. But it's a bit pricey for me..  (what's all that hardware go for Jordan.. ~$300?)

For my L3, I did a last minute on-site vendor purchase of a cool little, button cell powered, 216MHz beeper (fox and hound style) that was designed for falcon tracking for around $125:

It's okay.. you can also get 150MHz MURS transmitters for $70-80.  If you don't want to use a BaoFeng + analog meter (for directional gain fox/hounding).. then you can get a nice little dedicated hand held two element (see com-spec link) + wide beam yagi to get basic a basic bearing.. 

These cheaper analog beeper fox/hounds works pretty well for bare bones directionalityt (as long as your rocket doesn't land in a ditch or dip in the ground, then range is severely shortened ;).  Mine claims to xmit 30 miles.. but I think between 1-3mi is more real world.  

One of our vendors sells sa little 216MHz unti for like $75:

more specs + dedicated receivers:

Also.. here's a good write up on NICER, GPS/APRS trackers.. including this club's growing favorite, the Altus Metrum (if you can afford it):

GPS/APRS tracking is MUCH more cool.. you don't just get a bearing, but a bearing + distance.. or if decoding into a phone+app, you can get cross hairs of your rocket location on google maps. Seen this in action and it's very cool.

Jordan is the authority on this subject.

Hope that helps..

Jordan.. time to do another "Radio in Rockets" talk? :)
