[aprssig] simple and cheap digapeater?

I'm kind of partial to my Tracker2 (but I'm just a bit biased).  If you 
want a fairly small and affordable package, you can get the Alinco 
DR-135T (not the TP) and a T2-135 board to install in it.  Add power and 
an antenna and you're ready to go.  You can also hook a weather station 
up to the rear panel DB9 (or the front panel data jack, if it's a Peet 
Bros station - either way will work).  If you're on a shoestring, you 
can wire a $5 temperature sensor to the rear panel and get at least that 
much data.  If you get the standalone OT2m version, it already has 
temperature and voltage sensors.

It's easily configured by remote, even if you've got to go through an 
IGate and another digi or two to send it commands.  I've controlled a 
T2-135 in Oklahoma from my desk in California.

My next choice would be the Coastal Chipworks TNC-X with the digi 
add-on.  I'm not sure if it has any remote control capabilities, though.
