Hi Jason,
Why do the hardware exercise since the EggFinder receiver bonds to any 
laptopand your script does the chores nicely?  If one does APRS at the tracker 
would haveto have an APRS receiver on the 900Mhz ISM band.With the multiple 
X-bee trackers can you track with one receiver and what would 
you use to get an APRS receiver on the ISM band.Kurt KC9LDH

Y'know, now that I think about it you could probably do the same thing with 
multiple instances of xastir, with each of the n>1 instances using a unique 
alternate config (IIRC that's xastir -f /path/to/config/dir ). 

I've decided to go a different route and add APRS capability to my xbee 
trackers. Makes it easier to have multiple units on the air at the same time 
(multiple rockets prepped and ready, a tracker gets loaned out, multiple stages 
being tracked, etc) as well as simplifying ground station requirements, xbee 
configuration, etc. 

Looking at the eggfinder, I'm pretty sure it would be easy to wedge a 3.3v 
arduino mini type rig between the USB connection and the eggfinder receiver 
during construction and convert to APRS in hardware. Of course it would make 
the receiver the APRS station. I've got too many other projects in the air to 
add that one to the list, though.
