Because I need a DF locator beacon, not an APRS tracker (yeah, I sort
of changed gears in the middle of that last message). We usually fly a
DF beacon on our balloons in case the APRS tracker fails. We've been
flying a backup tracker on an alternate frequency, so the locator
beacon has become less important. I don't know if we'll keep flying
with the 2 tracker model and leave off the beacon, or use all 3
transmitters (primary APRS, secondary APRS, DF beacon), or maybe even
go back to the one tracker/one DF beacon once we get a reliable design

If I did need the absolute smallest APRS tracker and didn't want to
build my own transmitter, I would probably go with the pockettracker.
I vastly prefer the opentracker over the tinytrack, because it's open
source (and I'm a bit prejudiced against the PIC because I can't get a
free C compiler).
If I have a choice between an open product and a proprietary one the
open one gets my money, all other things being equal.
