## Mobilinkd
|
||||
|
||||
I use blueman-manager, a graphical tool to manage bluetooth devices. Because I
|
||||
actually hate bluetooth and its unpredictability...
|
||||
|
||||
right click on to TNC4 Mobilinkd, Connect with: serial port
|
||||
|
||||
that will create /dev/rfcomm0
|
||||
|
||||
open that port with KISS
|
||||
|
||||
~~~console
|
||||
$ sudo kissattach /dev/rfcomm0 wl2k
|
||||
AX.25 port wl2k bound to device ax0
|
||||
~~~
|
||||
|
||||
For now, I haven't enabled auto-connect of the serial port.
|
||||
|
||||
We can now use this in pat http when we select AX.25+linux
|
||||
|
||||
There are a few files that need to be prepared.
|
||||
|
||||
/etc/ax25/axports
|
||||
|
||||
~~~squid
|
||||
# /etc/ax25/axports

|

|
||||
|
||||
Out of curiosity I began another "research-session" because it is really time to get
|
||||
that Winlink back on my Linux laptop (I used OpenBSD on this machine for some months now
|
||||
and I haven't got a single chance to get wine onto that).
|
||||
|
||||
## Digirig
|
||||
|
||||
The Digirig gets controlled with `rigctld` -- I use different models for the
|
||||
HF and the FM rig -- but the rig configuration is the same for both:
|
||||
|
||||
~~~json
|
||||
"hamlib_rigs": {
|
||||
"my_rig": {
|
||||
"address": "127.0.0.1:4532",
|
||||
"network": "tcp"
|
||||
}
|
||||
},
|
||||
~~~
|
||||
|
||||
### Packet radio
|
||||
|
||||
Using <kbd>AX.25+agwpe</kbd> within pat in combination with Direwolf -- but
|
||||
this combination felt a bit slow (which might only be my subjective opinion).
|
||||
|
||||
~~~json
|
||||
"ax25": {
|
||||
"engine": "linux",
|
||||
"rig": "",
|
||||
"beacon": {
|
||||
"every": 3600,
|
||||
"message": "Winlink P2P",
|
||||
"destination": "IDENT"
|
||||
}
|
||||
"agwpe": {
|
||||
"addr": "127.0.0.1:8000",
|
||||
"radio_port": 0
|
||||
},
|
||||
~~~
|
||||
|
||||
The <kbd>agwpe</kbd> section is used by Direwolf:
|
||||
|
||||
~~~console {hl_lines="8"}
|
||||
% direwolf -c /etc/direwolf/direwolf.conf -p
|
||||
Dire Wolf version 1.7
|
||||
Includes optional support for: gpsd hamlib cm108-ptt dns-sd
|
||||
|
||||
Reading config file /etc/direwolf/direwolf.conf
|
||||
Audio device for both receive and transmit: plughw:1,0 (channel 0)
|
||||
Channel 0: 1200 baud, AFSK 1200 & 2200 Hz, A+, 44100 sample rate.
|
||||
Ready to accept AGW client application 0 on port 8000 ...
|
||||
Ready to accept KISS TCP client application 0 on port 8001 ...
|
||||

|
||||

|
||||

|
||||
~~~
|
||||
|
||||
The `direwolf.conf` file looks like this (comments removed):
|
||||
|
||||
~~~squid
|
||||
ADEVICE plughw:1,0
|
||||

|
||||

|
||||
IGTXLIMIT 6 10
|
||||
~~~
|
||||
|
||||
Direwolf will warn you if the input audio level is way off; I adjust them
|
||||
with the program `alsamixer` (<kbd>F6</kbd> to select the USB soundcard,
|
||||
then <kbd>F5</kbd> to list all devices, disable _Auto Gain Control_ with <kbd>m</kbd>
|
||||
(mute)).
|
||||
|
||||
### VARA FM
|
||||
|
||||
The corresponding configuratoin in the pat config file:
|
||||
|
||||
~~~json
|
||||
"varafm": {
|
||||
"addr": "127.0.0.1:8300",
|
||||
"bandwidth": 0,
|
||||
"rig": "my_rig",
|
||||
"ptt_ctrl": true
|
||||
},
|
||||
~~~
|
||||
|
||||
Start `rigctld`:
|
||||
|
||||
~~~console
|
||||
$ rigctld -m 1 -p /dev/ttyUSB0 -P RTS -s 9600 -vvvv
|
||||
~~~
|
||||
|
||||
I start VARA FM by running a small script called `varafm.sh`:
|
||||
|
||||
~~~sh
|
||||
#!/usr/bin/sh
|
||||
# Start VARA via wine
|
||||
|
||||
WINEPREFIX=/home/dominic/.wine-winlink wine "C:\\VARA FM\\VARAFM.exe"
|
||||
~~~
|
||||
|
||||
In VARA FM set the USB soundcard, adjust the volume in `alsamixer` and on your
|
||||
radio, set <kbd>PTT</kbd> to <kbd>VOX</kbd> -- I tried to use <kbd>COM1</kbd> but
|
||||
that crashed wine several times (that is why we setup _rigctl_ before).
|
||||
|
||||
If you need to stop rigctl: you can usually do that with
|
||||
<kbd>CTRL</kbd> + <kbd>C</kbd> but this might not work. So either stop the running
|
||||
pat process by hitting <kbd>CTRL</kbd> + <kbd>C</kbd> in the "pat terminal" or by
|
||||
killing rigctld with `kill $(pgrep rigctld)`.
|
||||
|
||||
This is not tested yet, because VARA crashed when I was out in the field and I cannot
|
||||
reach a gateway at home where I researched/tested the final settings.
|
||||
|
||||
### VARA HF
|
||||
|
||||
Back to the TX-500, the pat configuration looks like:
|
||||
|
||||
~~~json
|
||||
"varahf": {
|
||||
"addr": "127.0.0.1:8300",
|
||||
"bandwidth": 2300,
|
||||
"rig": "my_rig",
|
||||
"ptt_ctrl": true
|
||||
},
|
||||
~~~
|
||||
|
||||
I start rigctld like:
|
||||
|
||||
~~~console
|
||||
$ rigctld -m 2014 -r /dev/ttyUSB0 -d /dev/ttyUSB0 -p /dev/ttyUSB0 \
|
||||
-P RTS -s 9600 -vvvv
|
||||
~~~
|
||||
|
||||
Untested, untested...
|
||||
|
||||
|
||||
## Mobilinkd
|
||||
|
||||
I will use <kbd>AX.25+linux</kbd> in pat with the TNC4 paired via Bluetooth.
|
||||
|
||||
First of all, power on the TNC4 and pair it -- I use _blueman-manager_ for this.
|
||||
|
||||
Then we need the serial port -- right click on <kbd>TNC4 Mobilinkd</kbd> and select
|
||||
_Connect with_ <kbd>Serial port</kbd>
|
||||
|
||||
That will create a serial port at `/dev/rfcomm0`.
|
||||
|
||||
In order to use it in pat, we need to use `kissattach` on that serial device.
|
||||
|
||||
First we need to setup an AX.25 port called <kbd>wl2k</kbd> in `/etc/ax25/axports`:
|
||||
|
||||
~~~squid
|
||||
# /etc/ax25/axports
|
||||
#
|
||||
# The format of this file is:
|
||||
#
|
||||
# name callsign speed paclen window description
|
||||
#
|
||||
|
||||
#1 OH2BNS-1 1200 255 2 144.675 MHz (1200 bps)
|
||||
#2 OH2BNS-9 38400 255 7 TNOS/Linux (38400 bps)
|
||||
wl2k OE7DRT 1200 255 7 Winlink
|
||||
~~~
|
||||
|
||||
This needs also some configuration work in the pat configuration:
|
||||
|
||||
~~~json
|
||||
"ax25_linux": {
|
||||
"port": "wl2k"
|
||||
},
|
||||
"serial-tnc": {
|
||||
"path": "/dev/rfcomm0",
|
||||
"serial_baud": 9600,
|
||||
"hbaud": 1200,
|
||||
"type": "Kenwood",
|
||||
"rig": ""
|
||||
},
|
||||
~~~
|
||||
|
||||
Now we can attach a KISS interface to the serial port:
|
||||
|
||||
~~~console
|
||||
$ sudo kissattach /dev/rfcomm0 wl2k
|
||||
AX.25 port wl2k bound to device ax0
|
||||
~~~
|
||||
|
||||
Select your PacketRadio Gateway (CALLSIGN-10 usually) and connect using
|
||||
<kbd>AX.25+linux</kbd>.
|
||||
|
||||
To de-attach the KISS interface we need to kill the process by:
|
||||
|
||||
~~~console
|
||||
$ sudo kill $(pgrep kissattach)
|
||||
~~~
|
||||
|
||||
