AUDIO_ RX on WD

renebir
hello
I configured an audio receiver,
       "AUDIO_1                     localhost:1,0     f6bir/1       JN19CF  foobar"    
declare WSPR_SCHEDULE_simple=(
    "00:00                       SDR_0,6 KIWI_3,30 AUDIO_1,30"

 I listen to the frequency of WSPR from an FT897, the xx.usb.wav file is correct (5.2Mhz!), it is decoded by WSJT-X, during a replay with Player, the graph does record something


but there is no decoding or reporting, reading the .logs does not indicate anything.
Does a user know the correct config.
thank you

The AUDIO device is very lightly supported.
You should run ./wsprdaemon.hs -i to establish the functionality of our your linux audio input devices and set the record level .

Thank you

Read my recent forum post "Monitoring the operation of WD" to learn how to enable more verbose logging to the many *.log files which will log errors and other significant events on the many programs running.

Hi,

Are you sure the Pi is in NTP sync?  run 'ntpq -p' to check that.

Yes I think  because SDR_0 is spoting on 10 meters.
And the recorded  file 20200806T153800Z_1296500000_usb.wav (5.5Mo) is decoded by WSJT-X  via Player

Hello

Can you confirm the size of your audio wav files? You mentioned 5.2 but had MHz after it, and your last post says 5.5Mo - do you mean MegaBytes?

If so, it may suggest your audio settings are not right, the file size for 1200Hz sampling for a bit less than 120seconds for 16 bits should be about 2.7MBytes. Your sampling rate might be too high or your bit depth too great. You would be able to play those files, but the parameters would not be right for wsprd to decode.

The wav files are 2x the size of those at a working site.
I suspect your sound card is more than 16 bits or different from the $5 sound dongles I have tested.
i will need to experiment with your Pi for some time later today to test a fix.

Re: AUDIO_ RX on WD

Hello,
To close the thread, thanks to Rob and Gwyn, for their intervention in solving this RX AUDIO setting.
Everything is working normally now and after a few hours  recording the 30 meter band MERGED scheduler between FT897 input AUDIO RX and KIWI-SDR, using the same loop antenna with 2-way splitter.
I noticed very close report +/- 1dB and +/- 2Hz, in favor of the RX AUDIO chain. Reporter F6BIR/M
Rob the ssh is active yet a couple of days if you want to see the update.log and so on.
To be continued, thank you again for your help
