I was wondering if the transmeter could be replaced by one of the following which are more powerfull

Some of the could transmit up to 4km
I am interested also. I can solder. Do you have plans, list of components and printed circuit board layouts and where to buy components (Digikey, Sparkfun..)?
I'd like to try it out. I have a Samsung Galaxy Exhilirate smart phone and I belive it has Android, would that work?
My phone is on android 2.3.3 and my code always worked on my phone. I don't know where did you see it works only on 4.2
For my APC220, we can setup it on 418mhz that is not illegal. But I don't recommend the APC220, it doesn't go far enough. It barely goes to 400m (1200 feet) far.
I just pulled down your latest code. I see you have an apk now so I'll give it a try. thanks!
I built it and now I have the find in sky button. your map screen is starting to get cluttered with buttons/info/etc.
Yes, I know... I just want it to work for now. I'll beautifulify after.
But After thinking about it, the apk that was in svn was the stable version that was supposed to be on google play.
It's now available on Google play store: GPS Rocket Locator, it's the one with a red and yellow rocket.
Have fun.
There is the bong, that make a sound every time it receive data from the gps. It tell you if you are loosing your rocket or not...Congrats! I just tried it out and it works fine, but what do the different beeps and bongs mean?

The beep is probably the radar beep. I use it when the rocket is on the ground and I'm walking to the rocket but Kevin wanted it to locate the rocket in the sky.
The two beeps are probably interfering... ?
Ok so how do I buy the GPS module for the rocket? I cant build one.
You check the path of the rocket. If the rocket moves, it's still in the airs...ok. I heard the bong and the beep, but how do you know when the rocket is on the ground?

It wont move on the map. Just try it, you will find your rocketdo you have some minimum movement threshold? due to gps inaccuracies, the rocket is always "moving".

So, I had a chance to put my tracker up in one rocket yesterday. HPR flight to 5200 feet. This software showed the rocket on the pad right before launch but it appeared to lose the signal right on launch and didn't reacquire signal again until I went to recover the rocket after it landed. Signal was acquired at about 500 meters from the rocket. Not sure if it this was a phone, software or transmitter issue. I can understand having only 500 meters reception on the ground due to the rolling terrain, but I was hoping for better tracking in the air where I had line of sight to the rocket. I'll have some more opportunities to troubleshoot and get more experience with it this weekend when I'm at NYPower.

What telemetry system did you use ? Xbee, 3dr radio or APC220 ?
