<div class="PlainText">I've heard great things about the Egg Timer units.<br>
<br>
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?)<br>
<br>
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:<br>
<a href="https://marshallradio.com/north-american-falconry-products/north-american-falconry-transmitters/item/122-scout-transmitter">https://marshallradio.com/north-american-falconry-products/north-american-falconry-transmitters/item/122-scout-transmitter</a>
<br>
<br>
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.. <br>
<br>
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. <br>
<br>
One of our vendors sells sa little 216MHz unti for like $75:<br>
<a href="https://www.csrocketry.com/electronics/communications-specialists/tracker-rchp.html">https://www.csrocketry.com/electronics/communications-specialists/tracker-rchp.html</a><br>
more specs + dedicated receivers:<br>

<br>
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):<br>
<a href="http://jcrocket.com/gps-tracking.shtml">http://jcrocket.com/gps-tracking.shtml</a><br>
<br>
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.<br>
<br>
Jordan is the authority on this subject.<br>
<br>
Hope that helps..<br>
<br>
Jordan.. time to do another "Radio in Rockets" talk? :)<br>
