After WSJT-x in FT8 mode sits in a

hours, the Tx audio connection via
Flex DAX to the Flex 6600M transceiver
is lost. DAX is still connected to
the radio, but the connection from
WSJT-x is broken. The Rx audio
connection from the Flex 6600M via
DAX remains working OK. 
I recently found a similar, but different, problem 
with DAX and my Flex 6600M ... 

After sitting a while, when I transmitted and viewed 
my signal on the Flex panel panadapter, it showed that 
I was transmitting the narrow spike of MY signal, but 
the whole rest of the 3 kHz was rising up about 40db 
during the transmission ... and I was getting no responses. 

At other times, the base 3kHz would jump up and fall 
back down as if there was a noise burst. 

I found the simply clicking off the [TX] button on the 
DAX window, then click back on seemed to clear it. 

Also, I had the impression (nothing to confirm it) that 
this had something to do with my local LAN -- since the 
audio travels over that from the PC to the TX. 

Unfortunately, I cannot debug it any further because 
my 6600M went snap, crackle and pop the other day and 
no longer transmits anything.   :(



it's possible that your noise on Tx was an early sign of your rig failure.
