Wait until you get into the split channel stuff that Basil has been working on. It’s game changing in that you can run APRS and FLdigi at the same time, two different radios, same Raspberry Pi. Super Sweet. Thanks Basil!

I had a little trouble finding the getting started stuff since it wasn't a sticky message BUT I did find it and everything verifies OK so far. The app to start and stop ax25 is a huge deal in simplifying the operation of the HAT. Just ran it to change from APRS to FLdigi - sweet.

Re: NWDR15 Image observations
I just did the image download and apt-get from the Raspi script todayGood. I will fix that in the current image so the latest kernel is installed. Are there docs for V15 for install and config?Use the Getting Started Guide https://nw-digital-radio.groups.io/g/udrc/wiki/DRAWS%3A-Getting-Started I am not sure what AX.25-Control does on the desktop. It runs a whileThe purpose of the AX.25 icon is to run the ax25-start & ax25-stop scripts AFTER you have done the initial config (see getting started guide). The icon appearing on the desktop before the initial config script has been run is a mistake which I will fix. The intention of the icon was to make it easier to switch between packet & HF programs. The desktop icon will not work until an initial configuration has been completed. Also there are split channel scripts: split_install.sh split_status.sh split_toggle.sh split_verify.sh that enable running packet on one channel & HF programs on the other at the same time. I know that the V14 docs really don't apply to V15.nwdr15.img is mostly a program refresh release that adds split-channel and speed_switch scripts. Speed_switch is for easily switching between 9600 baud & 1200 baud packet without having to reboot. You can view the current versions of installed programs on the image here: https://github.com/nwdigitalradio/n7nix/blob/master/docs/IMAGE_README.md I will announce the nwdr15 image in the next couple of days. Thanks

Re: NWDR15 Image observations

I just did the image download and apt-get from the Raspi script today so the kernel I have matches what you listed above: 4.19.93-V7
Are there docs for V15 for install and config? I am not sure what AX.25-Control does on the desktop. It runs a while and then stops. I do a pidof direwolf and don't see it running either before or after running AX.25-control. I know that the V14 docs really don't apply to V15. Thanks Dave

Raspbian just updated their kernel to: 4.19.93-v7+ #1290 SMP Fri Jan 10 16:39:50 GMT 2020 so I'll be refreshing the image just to include that. Check your kernel version to see if you picked it up with the apt-get upgrade. uname -a /Basil Dave Christensen <dkc2030@gmail.com> writes:

NWDR15 Image observations
Dave Christensen
To the Group:
I am starting a new build from scratch using the new Version 15 image and have found the first gotcha during the first boot, just before doing the OS updates. I had a dead battery in the DRAWS hat and it would not get past "synchronising clock". I shut down the system and pulled the Draws battery and started the system this time bypassing the setting the clock problem. It is now updating and rebooting after updates. Thanks for building this image Dave - KD7UM

Re: AX25 over UDP is not working on
#nw14
Hi Bernard,
toggle quoted messageShow quoted text
I made your change suggestions and started from a default config to see where the script would fail. I found that ax25ipd could fail but still end up with a pid. I've added return value checks for both ax25ipd & kissattach. I'm not sure what program uses the AXUDP environment variable that contains the pseudo term name. https://github.com/nwdigitalradio/n7nix/blob/master/ax25/ax25ipd-start.sh Thanks Bernard. /Basil f6bvp <f6bvp@free.fr> writes:

Hi Basil,
I tried your improved script and found that it stopped in the middle at line with tail -1. I had to changed it in order to make the script run. Please find attached diff file. BTW many thanks for letting me know about option -t that changed. It did not notice that ! 73 de Bernard

Re: KC9KKORE: Second interface
Cowan Bowman
Thank you for the information and the links. I was looking in the N7NIX repository and didn't realize the information was in it's on repository. Basically, I wanted to see your approach in setting up pulseaudio and alsa. I wanted to have basic use of split channels for non ax25 HF using fldigi, wsjtx, or js8call applications and monitor on two separate radios. It is my 1st time using pulseaudio, and after some experimentation I was able to figure out how to set it up and even remotely listen to the radio audio with RealVNC Profesional server/client. Still have some fine tuning and additional testing. I opted to use the default distribution package settings and setup additional setting similar to your but using them in ~/.asoundrc and ~/.pulse/default.pa to split the channels. Great work guys and thank you again. Cowan

Re: KC9KKORE: Second interface
I saw that you referenced that you were able to run 9600 and or 1200I think John K7VE was referring to running 1200/9600 at the same time. Technically you can do that but there is a problem with PTT for each of the channels. I hope John weighs in on this. As far as switching between 1200 & 9600 baud, I demonstrated that at the 'Summer Gathering' digital conference. You can look at the script used to toggle between the 2 baud rates here: https://github.com/nwdigitalradio/n7nix/blob/master/debug/speed_switch.sh Also look in these 2 files for changes to ax25parms & kissparms https://github.com/nwdigitalradio/n7nix/blob/master/systemd/ax25/ax25-upd https://github.com/nwdigitalradio/n7nix/blob/master/systemd/ax25/ax25dev-parms Changes in parameters are conditional on existence of a file: /etc/ax25/packet_9600baud speed_switch.sh will be supported in the nwdr15.img /Basil n7nix

Re: AX25 over UDP is not working on
#nw14
I installed nwdr15.img and found that AX.25 was running very wellOK great to hear. Just an FYI, the final nwdr15.img file is not ready yet. In order to complete my system configuration I added a script creatingOK, I made some changes to that script so the temporary output files don't collide with the previously run mkiss command. Please let me know if the ax25ipd-start.sh script I checked in works for you. Also in order for the export command in this script to work you need to run it like this: source ./ax25ipd-start.sh or . ./ax25ipd-start.sh # Test like this: printenv | grep -i axupd and echo $AXUDP ax25ipd-start.sh is in my repository here: https://github.com/nwdigitalradio/n7nix/blob/master/ax25/ax25ipd-start.sh In order to work, the configuration needs /etc/ax25/ax25ipd.conf file.Note that the command line argument '-t' for listen: 2.0.1 has changed from previous versions. The latest version of listen defaults to printing a timestamp where as specifying the -t arg turns it off. -t Don't print a timestamp on each dump line.

Re: AX25 over UDP is not working on
#nw14
Hi Basil,
I installed nwdr15.img and found that AX.25 was running very well using your scripts ax25-start / ax25-stop. In order to complete my system configuration I added a script creating an axudp device for using AX25 over IP/UDP via Internet or via HAMNET (a high speed Ham data network using WiFi used in Germany and France). I called the attached script ax25ipd-start.sh. It must be used after ax25-start. In order to work, the configuration needs /etc/ax25/ax25ipd.conf file. I found that the distributed one is fine, thus I just made a copy of ax25ipd.conf.dist to ax25ipd.conf in the same directory. There must also be an axudp port declared in /etc/ax25/axports file. For this port I set speed to 115200 and paclen to 253. This axudp port may be used by AX.25 applications such as Node, FPAC, BBS linFBB. listen -chat will display all AX.25 network trafic including udr0, udr1 and axudp. Bernard, f6bvp http://f6bvp.org

Read this: https://github.com/nwdigitalradio/n7nix/tree/master/deviation and this: https://www.febo.com/packet/layer-one/transmit.html Look in your radio manual for transmit data input (PKD) sensitivity and input impedance.
