[aprssig] GPS'

Another alternative, especially if you can use it for other computing
purposes too, is to use a small single board computer. Think Raspberry
Pi or BeagleBone Black. Plug the USB GPS into it and pipe the NMEA
data out as serial to the D710. You can also share the data from that
single GPS among additional computers over a network by using gpsd. If
you don't need all that extra power an Arduino could work just as

The possibilities really are endless once you through one of these in
the mix. I realize it may be overkill for most of the applications
it's being used in but something to look at anyway.
