Hi, I think I have a simple recipe to reproduce this problem :
I have 4 WSTX instances connected to 4 slices on my Flex 6600M. All is working fine. My USB headset is connected to a USB port. => Disconnect the headset and after that, PTT will work but no transmit audio. Reconnecting the headset does not cure the problem, restarting WSJTX however does. Now, there are a couple of variants to reproduce the audio dropout : - reconnecting the headset with working WSJTX instances - doing the same on 4 WSJTX instances connected to SparkSDR. So, the Flex is not at fault. And lastly, sometimes it occurs that all 4 decode buttons remain active blue. 73's Erik ON4PB ------------------------------ Message: 3 Date: Sun, 20 Jun 2021 19:39:29 +0000 (UTC) From: Louis Fiore <mailto:ltfi...@aol.com> To: "mailto:wsjt-devel@lists.sourceforge.net" <mailto:wsjt-devel@lists.sourceforge.net> Subject: [wsjt-devel] Transmit audio dropouts Message-ID: <mailto:385049449.2854162.1624217969...@mail.yahoo.com> Content-Type: text/plain; charset="utf-8" Good Afternoon, Running version 2.4.0. Out of the blue I?ve noticed a few instances with my Flex 6500 transmitter keying on but no audio is transmitted. It happens randomly on both FT4 & FT8 about 10 to 20% of the time. Does anyone have an idea what may be causing this? 73, Lou W2LTF _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
