Thanks for the info. I tried putting in "DIGIPEAT 0 0 ^K9SWX-1$" in direwolf and setting my path in the HT to K9SWX-1,WIDE2-2 but it did not digipeat it. Do I need something else in direwolf to recognize the call from the HT to digipeat it?
Digging a bit deeper, this other option using a filter looks like it is working.
DIGIPEAT 0 0 ^WIDE1-1$ ^WIDE1-1$
FILTER 0 0 b/K9SWX/K9SWX-*
Does that look right? I used WIDE1-1,WIDE2-1 in my HT's path. So far I haven't seen any other WIDE1-1 packets other than my own get digipeated through my radio. I'm not sure if I would receive messages from other parties with that filter though. I tried sending myself a message via APRS.FI with a different SSID and it wasn't digipeated. I saw it show up from the local digipeater down the road but my test digi did not digipeat it.
