With most distributions, you should be able to enter this command at the terminal:

$ pacmd load-module module-virtual-source source_name=loop_source uplink_sink=loop_sink

Then set the gqrx output to loop_sink and the FoxTelem input to loop_source (be sure the sample rate is set to 48000 in FoxTelem).

Hi Folks,

I have just got an old Toshiba A100 laptop running on Linux. I have GPredict, gqrx and FoxTelem running.

Does anyone have any ideas on how to get gqrx feeding audio to FoxTelem? Thanks, 73, Terry Osborne ZL2BAC _______________________________________________ Sent via [email protected].

I assume it is a distro running PulsAudio and that all audio is working. In your next post please tell us what distro you're using, that would be helpful.

1) First install pavucontrol. Fire it up and also start GQRX and Foxtelem.

2) Pavucontrol has 5 tabs, go to the "Recording" one.

3) You will see something like "ALSA plug-in [java]: Alsa Capture     from .....". (Foxtelem is a Java application, hence the mention of Java).

4) Click on the rectangle that comes after "from" and you will get a number of choices depending on the number of sound cards. It will probably be two options only.

5) pick the options with "Monitor of" in front of it. If correct you will see the VU-meter below it come to live, which means that Foxtelem should be picking up audio.

6) Be proud of yourself for putting an old laptop to good use and start enjoying it.

If it doesn't work out mail me directly and I can provide you with some screen shots. The method that Paul N8HM mentioned will probably also work, but  you will lose audio output from your speakers.

HTH,

Hans
