[aprssig] time for APRS second generation network?

[Wes Johnston]

It could be expensive... but consider the likes of AGWPE... it does 9k6 on a
sound card.  You can easily have 2 sound cards (ie 4 channels/radios) hooked to
one PC.  Then you simply add a "real" 9600 tnc hooked to a heavy duty commercial
converted rig for the 9k6 TX from the super digi site.

AGWPE and UI-view work wonders.  UI-View allows you to define a number of ports
and have rules about what comes from where and gets digipeater out to where.  I
would _love_ to recommend a linux solution to this, but the linux sound modem
(as far as I know) only allows you to use the sound card as a monophonic souce.
 bummer.
