Re: What do you use for tracking?

It depends on what you want to do, and how much you want to spend.
If you only want to receive the track, then a cheap $25 Baofeng UV5R HT will receive the APRS Signals. Use a good magnetic mount antenna on your car.
I use a cheap USB GPS. I got mine from China for $15. It took a month, but it was $15. It has a mag mount, so I put it out the window on the roof, and tape it down with the blue masking tape. It also works on the dash, but there is nothing metal for it to stick to, and the GPS signal is not as good, but it works.
You can use a Raspberry Pi and a TNC-X or TNC-Pi, or I have also used a Winbook $89 tablet PC with TNC-X.
I connect the computer to the WiFi on my phone, and become an I-gate, so the information can be seen on aprs.fi, or a phone application like APRSdroid. That way people without a license or who do not have an APRS receiving system can also see the balloon system.
I use a mobile radio at 25W, and both I-gate and Digipeat. It helps everyone when the balloon is on the ground and the antenna is lying horizontally on the ground. If I am closest and get the packet, everyone else can get it also.
