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 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
Good. 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 while
and then stops. I do a pidof direwolf and don't see it running either
before or after running AX.25-control.
The 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
Dave

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.

Re: AX25 over UDP is not working on #nw14

Basil Gunn
 

Hi Bernard,

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.

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

One thing I forgot to mention is the speed_switch.sh script is dependent on the
radio you are using. I used a Kenwood TM-V71a. See the "set alsa config"
line towards the bottom of the file. Also you will need to create a
custom set alsa file if you are using split_channels.

I saw that you referenced that you were able to run 9600 and or 1200

Can you refer us to the code, configuration that allows for on the fly

I 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

Changes in parameters are conditional on existence of a file:

Re: KC9KKORE: Second interface

If you mean split channels for packet & HF using both channels of an
audio sound card ie. draws then:

https://github.com/nwdigitalradio/split-channels

or there is good split channel support in the up coming nwdr15.img
release:

https://github.com/nwdigitalradio/n7nix/tree/master/splitchan

You are right the Wiki entry for:

Re: AX25 over UDP is not working on #nw14

Basil Gunn
 

I installed nwdr15.img and found that AX.25 was running very well
using your scripts ax25-start / ax25-stop.
OK 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 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.
OK, 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.
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.
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: Xiegu G90: General Setup, I/Q panadapter setup via second input

Basil Gunn
 

- Any advice on configuration and levels to start with? I haven't found a
setup script for the G90 in the GitHub repository yet.
You are setting deviation so focus on ALSA PCM & LO Driver Gain knobs.
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.
Use John's web based draws-manager to determine the correct ALSA levels.
