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.

Xiegu G90: General Setup, I/Q panadapter setup via second input

Chris Metcalf
 

I recently added a Xiegu G90 to my "shack" and I want to set it up with my DRAWS hat. I believe I've figured out the right way to connect it up, currently via the CE-19 adapter board, but I'll probably switch to a direct connection to its 8 pin port soon.

Questions:
- Any advice on configuration and levels to start with? I haven't found a setup script for the G90 in the GitHub repository yet.
- What about CAT setup? I'm currently using the IC-7000 profile in wsjt-x but its somewhat unstable. 
- Once I get the basic setup done, I wanted to try getting the I/Q output set up as a panadapter - can I wire that in to the two input pins on the second DIN port to get a stereo input?

Thanks,
Chris

Re: New build of YAAC for Raspberry Pi 7-inch touchscreen

Basil Gunn
 

Just letting all the Pi users doing APRS with their UDRC and DRAWS
hats know that there is a new build of YAAC ("Yet Another APRS
Client") with a new optional feature to better support small and/or
low-resolution touchscreens like the 7-inch touchscreen that fits in
the Smarti Pi case.
YAAC version 1.0-beta145(07-Jan-2020) will be included in the soon to be
released nwdr15.img RPi image.

Thank you Andrew!

The Help->Check for Updates and Help->Install

Re: Split Channel

Jim Erickson
 

Thanks Basil and I understand this time of year.  I’ve had trying the split chan on my list to try for quite awhile but just haven’t found the time, even with time off.  I finally decided to give it a try yesterday, at the end of my vacation.  

I don’t know that I have a specific workflow in mind.  I tried this on an already setup image that has had the core_install run.  I imagined that I would have to stop ax25, then run the split_toggle (which would have to change the dire wolf config) and the restart ax25.

I’ve taken a look at the resulting direwolf.conf and I think I’ve discovered what the issue was.  It’s pointing to draws-capture-right and draws-playback-right.  Should be left, which I’ve switched, and now I’m decoding packets!

This is a super radio workstation now.  I can have 2m/70cm packet on one mini din and HF/JS8 on the other.  Brilliant!!

Jim,
First, thanks for trying out split-channels!

Some back ground.
Anna made a repo & got split-channels working around last April. I
picked it up last November & made some install scripts to configure
things a little differently.

If you follow the README.md file from
https://github.com/nwdigitalradio/split-channels
you will end up with the left mDin6 connector controlling an HF radio &
the right a VHF/UHF radio. What that does is make the right connector
device udr0 when it used to be udr1.

If you use the split_install.sh script from n7nix/splitchan it will keep
the left mDin6 connector for VHF/UHF which means it remains device udr0
and the right connector will be used by pulse audio for HF.

So November turned into December and I spent less time doing NW Digital
Radio stuff as the holidays started sucking up more of my time. This is
just to rationalize my excuse for what works & what doesn't.

The install script (split_install.sh) works OK.
The status script (split_status.sh) mainly used for debugging works OK.
The toggle script has never been tested but seemed like a good idea at
the time.

As it happened the split channel stuff worked well enough right away
that I started playing more with HF modes with packet happening on the
other channel. Seemed cool and I stopped script testing and did more
Hammy things.

I have not tried what you are describing which I think is:

Install split chan
 - which has ax.25 running on udr0, left mDin6 & HF on right mDin6

Run ax25-start when split chan is running
 - shouldn't have to do this and needs testing
 - pretty sure this will mess with the split chan config
 - you can run split_status.sh to confirm

I need to finish testing split_toggle.sh which will go from split chan
to both chans either config'ed for ax.25/direwolf or both ready for HF.

Will get back to you in a bit as I finish testing with a clean image.

/Basil n7nix


Anyways, I got a chance to try it as the prospect intrigued me. To be
able to have local packet traffic and be able to do HF, in my mind,
primarily JS8 with one RPi seems the dream. So I tried running your
scripts which seemed to work excellent. Easy to turn on and off, works
as expected in my books, almost.

I've verified, when running the
ax25-start, without the split-channel, I'm decoding local APRS traffic
in dire wolf. My volume is a little lower than I'd like, so I do need
to experiment with a different 2m rig, but the point is that I do
decode packets. Then when I enable the split channel and then
re-enable ax25-start and start listening for APRS traffic, I decode
none. I'm using the left mini-din for both split and non-split APRS
work.

I confess, pulse audio is very new to me. I think I roughly understand
it, but not definitively, and configuring it within linux is not in my
tools yet.

Any thoughts? I'm going to try a different 2m rig to see if that makes
a difference. I have verified that the right din works as expected.
Thanks for this!

Hi All and Happy New Year.

Basil, I believe I read on here somewhere that you were working on the split-channel operation of the Draws and making so that you could do HF and APRS/Packet with two different radios?  If it was, please read on, if not, hopefully whomever it was will see this.

Thanks Dave,

I did in fact have a clear view to the sky and waited at least 15 minutes, I have experience with gpsmon and the program never started.
i.e. never got the screen that starts with /dev/ttySC0 and displays the satellite list, time etc.

I did plug a different USB GPS device in which did lock and work with gpsmon!

Glad to know that and I will assume you are correct given I have zero experience with the DRAWS  unit.

Thank you for your response,

I am excited to be developing my app with your product and look for to continued support and success.
