+
+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 AX.25+agwpe 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 agwpe 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 ...
+DNS-SD: Avahi: Failed to create Avahi client: Daemon not running
+Virtual KISS TNC is available on /dev/pts/8
+Created symlink /tmp/kisstnc -> /dev/pts/8
+~~~
+
+The `direwolf.conf` file looks like this (comments removed):
+
+~~~squid
+ADEVICE plughw:1,0
+CHANNEL 0
+MYCALL OE7DRT
+MODEM 1200
+PTT /dev/ttyUSB0 RTS DTR
+AGWPORT 8000
+KISSPORT 8001
+IGTXLIMIT 6 10
+~~~
+
+Direwolf will warn you if the input audio level is way off; I adjust them
+with the program `alsamixer` (F6 to select the USB soundcard,
+then F5 to list all devices, disable _Auto Gain Control_ with m
+(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 PTT to VOX -- I tried to use COM1 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
+CTRL + C but this might not work. So either stop the running
+pat process by hitting CTRL + C 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 AX.25+linux 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 TNC4 Mobilinkd and select
+_Connect with_ Serial port
+
+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 wl2k 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
+AX.25+linux.
+
+To de-attach the KISS interface we need to kill the process by:
+
+~~~console
+$ sudo kill $(pgrep kissattach)
+~~~
+
+## Some systemd unit-file examples
+
+Put them into `$HOME/.config/systemd/user`.
