I work some with telemetry decoding in both linux & Windows, but have never produced .KSS files in linux.

If you have Wine installed to run the DK3WN decoder anyway, then the easiest path might be to play your audio file in Windows, feed the output to the appropriate UZ7HO software modem, and use Mike's "AGW Online Kiss" program which is at:

http://www.dk3wn.info/files/agw_online_kiss.zip

... you'll be left with a .KSS file which of course is what you're looking for to use in the decoder.

Not a "linux" solution, but the DK3WN decoders are Windows apps and I find them easiest to use with other Windows software. In contrast, decoders that run in GNU Radio on linux tend to be more compatible with output formats that we get from various linux programs.

I got one step further, but haven't succeeded yet. I have some recorded telemetry from XW2D and the decoded program from DK3WN up and running on Linux using Wine. The telemetry program needs a .kss file to give some useful data.

This is how far I got:

1. run a PulseAudio null sink with this command: pactl

load-module-null-sink sink-name=virtual-cable

2. play the audio with Audacity

3. run Dire Wolf

4. use pavucontrol to set the output (Playback tab) for Audicity and the

input (Recording tab) for Dire Wolf to the null sink

5. Dire Wolf will now happily take the audio from Audacity, which you can

see by checking the VU meter in pavucontrol

That's it.

Dire Wolf has the -l command line option to set a directory for log files, but no option to set the file name or any other hint on how to save data as a file. I know it is mainly used as a pipe to decoding programs, but what is the option to save to file? It is not always feasible to decode from a live signal, so what I try to achieve is to decode from recorded material. Any hints appreciated.
