Hello Paul,

Your comment that AX.25 and PACTOR are different protocols is what I expected.
My confusion is that all of the listed stations say PACTOR none say AX.25:

Just above the title bar of the table.. change the listed mode from "pactor" to "packet"


I have a nearby Ham club friend N5TW, who is on this list.? He is going to try to help me this weekend, but he is not a software person, so he can only help determine if he is receiving my signal.? The problem is that the list only shows him (as well as everyone else) running PACTOR.?

Once you see all the PACKET stations, then you need to think about which frequency you will be using, what directions your antenna works well / doesn't work well, and then don't forget about skip.? For example, if you're going to use 20m, then don't try to connect to a station close to you.. even in your own state.? Only try to connect to someone quite a ways from you.? If your antenna does 40m or 80m, then you can try closer in stations but only for the right time of day (80m is more of a night time band).



If Direwolf on AGWPE port 8000 is using AX.25 then how could this work?? Is there some other list of HF stations that use AX.25?? Even though the stations are listed as PACTOR do some also support AX.25?

Start playing around with that list and map.? Also check out VARA which is very popular these days with the Winlink crowd though please note that Direwolf doesn't support VARA.? VARA-FM (for HF) and VARA (aka VARA HF) modem programs run under Windows but there are guides on the Internet to get it to work under LInux using WINE.? ARDOP is also available for Linux but there are less and less stations running it.

Hello Paul,
Under the link you provided, there is a row of 'Radio buttons' right above the actual roster that selects the page you want to have displayed. Switching that to 'Packet' will show the stations operating AX.25 (with their supported baud rates) you're probably looking for, instead of those PACTOR nodes.

Good!? It sounds like your issue is just on audio tuning and then the rest is up to how much RF power your radio has,? how good your antenna system is, HF propagation, etc.



I am having trouble both conceptually and practically understanding how the pieces fit together.?

There must be some FSK frequency configuration somewhere, but I don't know how this works.

PACTOR and AX.25 are totally different technologies.? When PAT talks to Direwolf via AGWPE, it will ask Direwolf to create a connection to whatever callsign you specify.? This then assumes you configured Direwolf to use a 300bps AFSK modem.?

I-Gate when internet available, Digipeater otherwise

 

Hi,

Not sure if this has been discussed before but I couldn't find any info.
Is there an option that would made Direwolf switch between the modes of operation based on the internet availability?

My setup would act like an I-Gate when the internet is available and when there is no connection, it would switch to a Digipeater.

Let me know if it's doable, other than creating scripts to monitor internet connection and switch the direwolf service between two different config files.

Thanks,

Re: enable "Last telemetry:" on aprs.fi info?

 

Thank you for your reply and explanations. There were several telemetry entries last year, and you helped me recall that those were manually from my Yaesu FT-2DR.
Re: enable "Last telemetry:" on aprs.fi info?

 

I am not sure what telemetry you are expecting to see, but those are beacon packets, not telemetry packets.
I know there is some statistical information on aprs.fi, but "telemetry" is data you specifically send in a telemetry packet.
? ?It also includes other information to interpret it: PARM, UNIT, and EQNS to explain "Signals", "Units", and "Equation constants" to explain the sent data.

Review the APRS-Telemetry-ToolKit.pdf document in the DOC folder or online.

Re: Heads up: New Raspberry Pi OS Bookworm 12.2 OS upgrade breaks Direwolf v1.7 GPIO pin access

 

Did you try to install it using apt?

do

sudo apt update

sudo apt install libgpiod-dev

It's available in the repository for both Buster (Debian 10) and Bullseye (Debian 11) on two old model B Pis I have in service, both running whatever image the Pi Foundation supplied at the time.

sudo apt list libgpiod-dev will show if it's available.

The good news is that when I set up a clean SD card with 32-bit Bookworm and followed the instructions in the new Radio Interface Guide and everything is peachy. Somehow, there is no libgpiod-dev package on my other Pi and I'm not sharp enough to figure out how to get it there.?I checked both with dpkg -s libgpiod-dev.

Thanks for the help. I'll contemplate this a bit more before raising the white flag.

I have an aprs bidirectional igate using the latest direwolf development version. When I look at the station info page on aprs.fi, the "Last telemetry:" entry is dated over a year go. What direwolf.conf entry determines this, please? Currently I have:

Did you type the command or copy/paste it from somewhere?
Some document editors will change the ASCII "-" (minus, dash, hyphen) to some other non-ASCII character which looks the same on the screen.
