Setting up an APRS digipeater with direwolf and xastir on a Raspberry Pi 3 running Stretch. There are multiple ways to accomplish this. This is one of the methods I use.
This is the digipeater that I run in my Jeep. It helps my Baofeng APRS setup be heard when I am in the backcountry hiking/hunting. It could also be used as a fill in digipeater for your ham shack.
Compile Direwolf
git clone www.github.com...
cd direwolf
make
sudo make install
make install-conf
Get sound card info
arecord -l (note:that is a lower case L)
Install Xastir
sudo apt-get install xastir
Get Lat/Lon - whatsmpgps.com

I appreciate your thoroughness on your videos. They are very easy to follow along and you keep in short by getting to the point and not rambling. You also include the commands that you use in the video. Thanks again AI5HV.
Thank you for this post. I’m building a APRS system with the raspberry Pi and the Northwest Digital DRAWs board. It replaces a signal link and adds a real-time clock and GPS. I hope to have it working with the same software and the radio can be any that has a packet port.
Good video. Used this to setup a digipeater on a Linux Mint box I had laying around. My TNC won't go up to this point, still troubleshooting. Thanks for the video!
This is incredibly helpful. My direwolf doesn’t seem to have a symlink, or I can’t find it. I have a signalink, too. I think this is my last hurdle before I can say success!
Start direwolf from the command line with “direwolf -p -t 0” note: that’s a zero at the end.
great stuff as usual Jason - thanks for your efforts
Thank you for making it so clear, hoping to make a Airmonitor APRS here in the UK, I am Using a SDS011 and a Raspberry pi.Best 73's M1SKI
I noticed with the Build a Pi v2 build that Xastir complained about a hard fail when starting the KISS TNC. To fix this I had to change /tmp/kisstnc to /dev/pts/1 for the interface port in Xastir
That is an issue that was introduced in Buster. Just know that your pts # can change.
THANKS!
Great video. Planning on putting one of these puppies in the SUV!
Works great in the mobile. I run one of mine there. Can turn on/off as needed. Thanks for watching! 73, de KM4ACK
Jason, thank you for your informative tutorials! Using Direwolf and Xastir, is there a "simple" method to set up beacon text or status messages? Thank you again !!
What is a APRS digipeater? I watched the video to learn what it was and how it can be of service to me. I am new to all this and just got my new RasPi4. Love your videos though. But just a word of thought, maybe explain what the technology does. ;-)
In the simplest of terms, a digipeater is a simplex repeater for packets. Here is a more detailed explanation. www.aprs.net.au/vhf/aprs-digipeaters-101/ 73, de KM4ACK
Very helpful. Thanks for posting, Jason! 73 de AB3ZI
Can you use xastir just to monitor aprs traffic? I do not have a callsign. With APRS-IS 32 i can do that, but with xastir no stations showing up...
Jason, If I wanted to run an iGate at home in which I'd not be moving, would I need to run and use Xaster?
Thanks,
Mike
There are several different ways to run an igate at home. Xastir is one of them that works well and is the one I am currently using for mine.
Thanks for the Video..
Hi, nice video, I just setup my pi and I get all the way to 8:10 and it will not go up under serial kiss tnc and help with that?
Thanks, great video!
Great information! One question ... if I had a gps tied to the pi, how difficult would it be to have the position updated dynamically while traveling. My vehicle has a WiFi hotspot with internet access through a cellular connection. AC1EW
Not hard at all. I run it that way in my Jeep with an Yaesu 857D. You just need to configure the GPS in xastir by adding a new interface. Thanks for watching! de KM4ACK
Great Video - Just wondering if this would work with a lesser expensive USB sound card instead of using the Signalink, or is the audio quality of the less expensive type sound cards substandard for packet radio?
It can be done with a less expensive sound card. The only downside really is the difficulty in setting the system up with sound cards that don't have VOX built in. 73, de KM4ACK
So in order to have just an igate - in direwolf i would look for and make sure there was no RF out? I really just want to make a mobile iGate for my long road trips - but there aren't always digi-peaters near by.... I know I could just use my phone LOL but hey I wouldn't really learn anything new.
Have you ever given any thought to using Direwolf/Xastir to digipeat messages from ISS?
I haven't but it wouldn't be hard to do.
i am using a straught KPC3 tnc in kiss mode. WHAt do i need to do differently for this setup?
Great video. Thank you. One Q: how do you only permit stations heard on the RF side, and not feed the map from the internet?
In xastir, look at Interface/interface control/networked AGWPE. Check allow RF to inet only. This should accomplished what you are looking for. Thanks for watching! de KM4ACK
If your direwolf.conf contains a "dash" after it, your audio input may not work!
Great Information. I have everything running. but Serial Kiss TNC will not go up. Any help?
This video is long in the tooth now. I suspect you are using /tmp/kisstnc which won't work on Buster. After direwolf starts just to the right of /tmp/kisstnc you will see /dev/pts/X where X is a number. Use that instead and you should be in business.
Great explanation and video!
If APRS packets from multiple sources are sent, can you view everyone's location on the Pi without internet access?
I want to use APRS with my friends while out in the backcountry so we can view each other's locations without having internet access. Thanks!
Yes you can
ThanK you for the video. I have been trying to get direwolf loaded for a few day and your video fixed my problem! How can I connect a rtl-sdr instead of signal link? I’m am just trying to make an igate but can’t figure out how to get it to work. Thanks KD9HWU
You should check out @SignalsEveryWhere on TH-cam. He is the master of all things SDR related to ham radio. 73, de KM4ACK
It sounds like what you need is a virtual audio, this allows you to pipe audio from an application such as sdrsharp into your igate. You could use rtl-fm which is a lightweight command line SDR client. This video shows how to use the cables th-cam.com/video/RGvrT40xkSY/w-d-xo.html
Thanks for your videos! (I'm becoming a Pi fanatic)
Do you think the Pi zero or zero W has enough horsepower to play this role?
-Rob
Can't say as I have never owned a pi zero. For the slight cost difference, I would get a pi 3. There is a way to run a digipeater with just direwolf. If you went that route, the pi zero might work. 73, de KM4ACK
@@KM4ACK Fair enough. I have a Pi 3 B, but was coming at it from a physical footprint & power consumption perspective rather than cost. I have been playing with the AREDN mesh networking and I'm trying to come up with a list of network 'services' that can be offered. Some things need more horsepower, like VoIP (a zero or zeroW wouldn't fair well for this), others need less.
Thanks again for the info. you are putting out there!
@@rkaag99 Gotcha. AREDN is a ton of fun once you get a few people on it. I have even shown how to do Pat Winlink p2p over AREDN in a past video. th-cam.com/video/CCF8r236yiA/w-d-xo.html And while I don't have a vid on it, I manage a full blown PBX on our local AREDN. 73, de KM4ACK
So how does the APRS Digipeater enter/exit to the radio? i.e. where does the radio/sdr fit-in, and what kind of rf modulation does it use?
What about services like SMSGTE? Can anyone run a server like that (which takes RF->SMS, and SMS->RF)?
Finally, any thoughts on specialty "APRS hardware", like Mobilinkd TNC3, SainSonic 2015/AVRT6.. are these the same as doing it on the Pi?
You will need some sort of sound card interface (ie signalink) between the pi and the radio. If you connect it to the internet (ie igate) you will gate any traffic to or from services like SMSGTE. As long as you have a radio license, you can run an APRS digi/igate. Mobilinkd would work great here for your sound card interface and it's not limited to APRS. It works equally well with Pat Winlink over 2M. 73, de KM4ACK
Has anyone successfully utilized the MMDVM transceiver and direwolf or other software to create an analog APRS Digipeater/iGate? Seems like it could be a very cost effective option.
It almost works. The direwolf screen just flashes continuously. Seems I can never get any pi programs working. frustrating little toys.
Flashing direwolf in buster is a known issue. Easy fix by adding "-t 0" to the end of your direwolf start command. So if your normal start command is "direwolf -p" mod it to be "direwolf -p -t 0" Note: that is a zero and not the letter O.
@@KM4ACK I am running Buster. That takes care of that issue, Thanks. Now to get the interface control to run. I'll go back over the video again. I must have missed something
Thank you for this video. Can you share what VNC viewer are you using on your Mac?
Sure thing. It’s Real VNC. 73, de KM4ACK
Very helpful videos. I'm running direwolf, xastir, IC 7000, signalink. All works when interface is internet server. When I set interface to to serial KISS TNC I receive and see stations populate the map, but I don't transmit my position and don't show up on aprs.fi. I've tried several radio and direwolf settings. Any suggestions?
Checkout the video I just released. It covers everything in great detail th-cam.com/video/AYhVDgRJBNw/w-d-xo.html
Turns out alsamixer needed to be adjusted up to get my configuration working.
Problem: when I run direwolf -p I get a flashing return. I have the same responce as you have except the line "ready to accept agw" preceeds the line "ready to accept kiss tcp", not as the last line.
When I first ran the direwolf -p I did not have my Signalink attached. I attached the Signalink and re-ran the Direwolf -p command which resulted in the above.
Suggestions
WG2W (again)
It is a known issue in Direwolf on Buster. See this page for additional details. dl1gkk.com/setup-raspberry-pi-for-ham-radio/ 73, de KM4ACK
How do you configure the PTT as this might be the only kit for APRS I may have with me ?, as with the comment by A and the Xastir icon I have a similar problem with my Direwolf icon which when clicked and boots up in a window it flashes, I dont know how to change settings to add the -p -t 0 command into the icon ?. as always great stuff please keep up the good work and thank you Jason
I use this with a signalink which has VOX built in. No need for additional PTT command. If you are using a different sound card, try consulting the direwolf forum groups.io/g/direwolf/topics Start direwolf from the command line with the command 'direwolf -p -t 0' to stop the flashing. Don't use the icon on the desktop. 73, de KM4ACK
@@KM4ACK Thanks Jason, can the command direwolf -p -t 0 be added so the icon on the desktop work direct without remembering the dw-p etc thing ?, looked online and being new to the pi and pi scripts its all a bit foggy on the old grey cells hi hi, keep up the great work between you and Julian my portapack set up will rock I cant thank you all enough. 73.
Just got a Pi 4, and am stuck at the arecord -l (lower case L). No devices come up. Do i need a piece of hardware here?
Yes. You will need some kind of sound card interface. A signalink, wolphilink or the like to be a digipeater. It is the interface between the pi and the radio. If you prefer the mobilinkd TNC & a baofeng, check out the video that released this morning. th-cam.com/video/gtvtWL3_prA/w-d-xo.html 73, de KM4ACK
I’m looking for what is not needed for the igate setup. I want to build a portable digipeater that will stay in my truck and will not have internet access when I’m out hiking. The truck will be parked at a high point with reliable access to an igate and my HT. The HT on my backpack will not have reliable access to the igate.
You can use this setup and leave off the aprs server configuration.
@@KM4ACK Thank you for following up. I went through this again and see that this will not be a straight forward to create a fill-in digipeater with a headless raspberry pi. I'm looking for a way to run a TNC digipeater via the console without X and automatically at boot up.
jermlac you will need to checkout a pure direwolf solution. I don’t have a video on it but direwolf is capable of running a digi on its on without X.
What audio settings would i need to change on the pi to communicate with a baofeng?
The best approach is to use a signalink or similar sound card with VOX built into the sound card. When using the Baofeng, if you attempt to use VOX built into the radio, most of the returning packets won't be decoded because of the long VOX delay with the Baofeng.
Thank you for the post. I have a question do you not need AX25 running to allow this to work?
AX25 isn't needed in this case. Thanks for watching. de KM4ACK
10:02 Batterie was empty 👀 'Bleep'.
I looked at my smoke alarms when I heard the chirp! LOL
Saved thanks. I’ve been trying to find the best solution for some time and used to have a TinyTrak3 w/FT1500M but that unit failed and since I want the TX/RX functionality am going to go with a TT4+PI and. Suitable high power radio as I have not had consistent results with an APRS+HT in my area. Would be also nice if I can figure a real-time APRS PI message display app.
Xastir will allow you to send/receive APRS messages. Thanks for watching! de KM4ACK
I'm back at it. Failing at using a TT4, I bought a Tracker 4 but it is not quite usable yet. Well, right now I am powering the Tracker 4 off a Pi4 and am configuring that following your instructions. Need to get the USB GPS feeding Xastir but at least am headed in the right direction. :-)
What changes would be made if you['re connecting the Baofeng right to the pi? I have a cable that would connect it directly to my Android phone and am using a USB to audio adapter to connect it to the pi. So, no "TNC" per se, unless it's built into the cable.
Direwolf is the TNC. You will need the cable, a soundcard, and a way to trigger PTT on the Baofeng. Don't use VOX on the baofeng. It will transmit but won't receive very well. mikebeach.org/2015/10/27/using-kf5inz-easy-digi-with-baofeng-uv-b5-or-uv-b6/comment-page-1/
@@KM4ACK Thank you for this. I was trying it with VOX, but it keeps kerchunking. I'll have to check this site out.
@@KM4ACK So, I'm using the B-Tech APRS-V01 cable. it's meant to be a TNC between your phone and the radio (to run APRSDroid). I take it that I need a different cable altogether. Thanks. :)
Xastir has to be running all the time for a full time station right?
Yes. Xastir has to be running for it to work
I am running a new Raspberry pi4 and having a little error with kisstnc when in a terminal sudo kissattach /tmp/kisstnc wl2k I get this error kissattach: /tmp/kisstnc: open: Permission denied. In Xastir interfac control properties /tmp/kisstnc never goes up. I can make everything work by using /dev/pts/1, but this changes every time opened. Please can you help me?
I have the same issue. Something changed in Buster. Never had that issue with Stretch. Haven’t had time to dig into it and see if I can find a fix. If you figure it out, please report back. 73, de KM4ACK
I was fine till I got to the arecord -l part. Is there something I need to make this work? Thank for any help. It wouldn’t display any message, do I need a usb device?
Yes. You need a USB sound card. A signalink is probably the easiest to configure.
Hi, I know it been a while. I'm trying to follow the install using an rp4. I have been successful with wsjtx, js8call, and pat ardop. I s configured and started "direwolf -p -t 0". When "sudo xastir" when I add and start the KISS TNC I get the following error: EACCESS ERROR Interface Error! Error opening interface 0 Hard Fail.
I have checked for mistakes, but I don't see any. Any guess on what to do? Thanks...
What port are you using for the KISS TNC?
@@KM4ACK In dire wolf.conf I see AGWPORT 8000 and KISSPORT 8001.
I think we are talking about two different things. Can you email me screenshots of the failure please. Mycall@arrl.net
@@KM4ACK I am also getting the same error when I follow your Kiss tnc set up on a rpi4b using buster. I started direwolf using the -p -t 0. Have you got a fix for this yet or know why it wont connect? Thanks
Stuart Dingle Buster is different from Stretch. Use /dev/pts/X that direwolf shows when you start it. X will be some number. Usually 0 or 1.
I'm still trying to fathom out how all this works... what exactly is taken on the hike and what is in the vehicle? I'm new to all this hence why I'm asking for clarification. Cheers.
So an HT is taken on the hike. A full size (50W) rig with a raspberry pi connected to it is in the jeep running the digipeater. The HT sends out a signal which is heard and repeated by the rig in the jeep. 73, de KM4ACK
Thanks for the reply. So the HT is being used as is (so not using the setup from your previous video showing the HT linked up via cable to APRSDroid,) it's the digipeater/raspberry pi in the vehicle sending APRS location data instead? So how does this know your location from the HT, is this embedded in the radio signal? The reason I ask is I'm about to purchase the cable from the first video but don't know if it's actually needed when using this setup.
The HT needs a GPS signal. This can come either from a HT that has one built in OR from a setup using a cable and APRSDroid. When using APRSDroid, the app uses the phone's GPS and then passes that data to the radio through the cable seen in the other video. 73, de KM4ACK
The video title is 'APRS Digipeater'. You didn't say anything about the radio you have connected to the Raspberry Pi. Surely what you have built is actually just an i-Gate?
It is a full blown digipeater connected to an 857D. 73, de KM4ACK
@@KM4ACK - of course. You were using the Signalink as the audio interface.
I have a Raspberry Pi 4 and have raspbrian buster installed, Can i use the same commands you did?
Also does direwolf and xastir accomplish APRS or tie to it?
