Anyone tried to run TR4W contest logger with SunSDR in Linux? It is a real problem, with my K3 connexted to an USB port was not a problem to symlink the port with radio to /.wine/dosdevices but it seems impossible with SunSDR2 DX. I tried SDC, tty0tty and socat but all causing an “access denied” message due to lock. I need to stay on Linux and TR4W is only program running flawlessly in Linux with wine. Also I love this program due to its excellent external database support, AutoSend option and many other bells & whistles. So, it is very important for me to solve this problem. Does anybody have any ideas?

How to run TR4W contesting software under Linux with SunSDR2 DX by Expert Electronics

The famous Windows contesting software TR4W (see tr4w.net/) works in Linux. Only your radio and keyer should be connected to a port which is symlinked into /.wine/dosdevices. This can be done in this way:

ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com1 << Winkeyer USB connects com1 of TR4W
ln -s /dev/ttyUSB1 ~/.wine/dosdevices/com2 << your radio connects to com2 of TR4W

Of course, any SunSDR2 is not supported by TR4W itself. Fortunately ExpertSDR2 software has the Kenwood TS480 protocol emulation (Options → CAT) which can be evaluated.
First, you need tty0tty - linux null modem emulator. It can be downloaded here:
github.com/freemed/tty0tty
The installation is described in detail also here.

To make tty0tty persistent across boot, edit the file /etc/modules (Debian) or /etc/modules.conf or /etc/modules-load.d/modules.conf (Ubuntu) – simply add the following line:

tty0tty

tty0tty creates four pairs ports in /dev/

/dev/tnt0 <=> /dev/tnt1
/dev/tnt2 <=> /dev/tnt3
/dev/tnt4 <=> /dev/tnt5
/dev/tnt6 <=> /dev/tnt7

so we can use them as follows:
In ExpertSDR2 software (Options →CAT) define CAT on port name tnt0 (we evaluate the first pair tnt0<=tnt1)
In

/.wine/dosdevices

create a symlink tnt1 (which is paired to tnt0) to com3

ln -s /dev/tnt1 ~/.wine/dosdevices/com1

Your new tnt* ports won’t work unless they are chmoded

sudo chmod 666 /dev/tnt*

To make the chmod persistent across the boot, create an udev file named

80-tntport.rules

with a single line:

KERNEL=="tnt[0-7]*",MODE="0666"

and put it into your

etc/udev/rules.d

(applies to Ubuntu, other distros may have elsewhere in /etc)
Finally, open TR4W and define the radio on the serial port you already created.
ENJOY!
