Hello, I'm back with some more Information :
- the soundcard is not a cheapie :-) It's a Terratec Aureon I've used it several years for decoding NOAA sats, without any notice, even under linux and on RPI2 together with wxtoimg. - the problem looks like an RPI USB problem. I have been searching the internet and found "dwc_otg" problems.....there are many forum entries and debug hints like kernel command line options etc., but at least nothing will help solving that usb-driver (that is my conclusion). - Main problem is of cours that linux-usb handling will loose some audiodata -> this causes the /usr/bin/JT9 process to stop working correctly (lower cpu usage than normal), no decode no waterfall This stops processing audiodata even after a short wile audiodatat is back again.... --> wsjt-x gui should supervise JT9 process to observe any irregularities , like it does when JT9 process is shut down manually. 73 Frank DB5FP > Hi Frank, > I've been running wsjt-x 1.8.0 on a rpi3 for weeks now, using a neat > qrp-labs receiver variant.
