Hi Fred,
Yes, the direwolf software is excellent.
As for the AllStar APRS support, it's pretty limited in operational scope,
and I don't typically use it. Where I want to send out APRS beacons, etc.,
I just use the stand-alone aprx software, which is full featured and in
the hamvoip-packet-tools package.
More details about the AllStar APRS support can be found here:
