I was going to suggest something out of the Alix line for a support PC,
since they are low power (again, in comparison to a 100 - 300 W desktop
computer) and give one access to the tools needed to remotely control a
TNC (however, one would need to add a serial port, probably using USB).
2.4GHz or 5GHz at the site would likely be a hit or miss proposition
unless a directional antenna is used and some power.
When you're dealing with a site that has line-of-sight to over 50 miles
away, there's a lot of noise that can be picked up.
I assume that this digi will be shared with a repeater that has a very
good antenna (DB-224/8/Super Stationmaster). =)
