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
switchng between Direwolf 9600/1200 baud packet speeds.
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

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

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:
Creating Virtual Sound Cards for the UDRC or DRAWS

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

no but i'd be interested in it... would be nice to have dmr access to our repeater :D

Morning,

I found this morning a bunch of UDRC boards that I "lost" in a house move. A project that I put on the long finger quite a while ago was a DMR to Analog Bridge to get our local Analogue Repeater System onto a DMR TG without tying up a Slot on a repeater.  So far the UDRC is being recognised by my PI-2 but I'm wondering is this a route anyone else has travelled before me, or am I wasting my time.

Do you have an ETA for shipping the orders?

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
Plugins menu choices in YAAC will easily install the upgrade and
optional smallscreen plugin.
