I did NOT configure APRS-IS in Direwolf as it normally wouldn¡¯t have an internet connection. I¡¯m using hotspot on my phone during development only, pretty certain my packet went out via RF
I am pondering a digipeater as my next project, have to come up with a radio.

?Good. So whether or not a digipeater heard you, an I-gate did to forward your packets.
On the other hand, did you configure Direwolf to talk to the APRS-IS, such that the packet was sent directly to the Internet without going over RF? Check the digipeat path of the packet on aprs.fi and see who forwarded your packet to the Internet (and if the packet went through any digipeaters before reaching the I-gate).

I _just_checked aprs.fi, my PBEACON, while location needs tuning, went out!

?Have you looked at the aprs.fi map for your area to see if there _are_ any digipeaters in your neighborhood? If there aren't any, there won't be anything to hear you. And there are many places in the US with poor or non-existent digipeater coverage. Also, remember that the 2-meter band is more-or-less line-of-sight; if you can't _see_ the digipeater antenna from your station's antenna, you probably won't get through.
I have a problem like that with my QTH on the north side of a hill, such that I can stand in my backyard on the ground and look _down_ at the antennas on my roof. Good thing for me there are digipeaters to the northwest and northeast of me to help me bounce around this chunk of granite.

I've attached a screenshot of the DireWolf -dgt startup.
MY APRS Rig is fully outdoors.
I don't see a reply from a digipeater in response to my outgoing packet(s).
I am using Raspberry Pi 64-bit OS (Bookworm) with Pi desktop, 2024-07-04.
I have changed TXDELAY to 50, TXTAIL to 35 and still not getting "out"
My coordinates are for Central Illinois, USA, lat=40^41.47N long=089^28.37W

Hello Doug,
I looked at your .docx file but it doesn't show the output of direwolf starting up. Can you please add that?
I've been running APRS/Dire Wolf mobile tracker successfully since 2020 with the same physical setup. My SD became corrupt and like a dummy, never made a backup.
Hmmm.. bummer. SD cards can die if you don't use good quality cards AND tune the Linux operating system to minimize writes.
I'm trying to get it running again with Dire Wolf 1.8 Development D and having a couple issues:
*
GPS doesn't move within Dire Wolf (stuck at 4041.76N/08928.70) but moves with GPSMON
I'm not sure what those coordinates are supposed to be. Maybe you meant 40.417600, 89.287000 (the middle of China). Anyway, this could be a matter of permissions. Are you using gpsd with direwolf? When you're doing testing with Direwolf, are you doing this OUTSIDE with a clear shot of the sky? A lot of inexpensive GPSes just won't get a good lock w/o exceptional signal levels. Btw, if you're using the gpsd approach with direwolf, you should be able to run tools like cgps/xgps/etc while direwolf is also running. With that parallel view, you can confirm if you have good GPS lock, the location is correct, the time is correct, etc.
* Not getting digipeated
I believe the issues are related but can't find the common denominator.
What makes you think your station isn't getting digipeted? Not showing up on an APRS-IS map? If so, that would be expected as you need to first send your location to APRS-IS before it will believe other data coming from your station. You can work around this by sending a PBEACON with a static location just as a test.
Dire Wolf launches without error using -dgt
Please show us all of that startup detail.
I've attached the script that I'm using to create my new installation for reference.
Few things in here:
- Which version of Raspberry Pi OS are you installing? The GUI desktop or the Lite version with no GUI?
- The use of the "pi" username is deprecated. Please use something else like "doug" or whatever
- Do NOT remove PulseAudio. You will damage the resulting OS install. Things might continue to work for Direwold since it can use ALSA directly but the GUI environment might have permanent issues.
- Your TXDELAY is way too fast. Is this your radio ( )? If so, that's an SDR based radio and most of those radios are very slow.. as such, I recommend to START at a setting of "45" meaning 450ms to properly key up and be stable on-frequency before the packet audio tones start getting played. The final tuning might need more/less delay depending on how your radio actually performs. You also might need more TXTAIL time as well.
Using the overlay file system can really help minimize writes to the SD card but it can become a major PITA when you want to do OS updates, etc. Your choice but if you want to see a less invasive list of hardening, see:
