Radio: Flex-6300
software: 1.4.16
Direct connection via NIC to computer

The radio was working fine. I had just selected 15 meter. I was adjust things and it suddenly stop working, by that I mean no audio output, there was data on the spectrum scope but nothing on the waterfall, and I lost complete control and then smartSDR crashed.

It displayed the "Connection Lost" popup box with the message "the connection to the radio was lost. Please reconnect". I click the OK button and the radio setup window appeared. It showed that my radio was already in use. So I could not reconnect. I also looked at the activity Ethernet LEDs on the computer and they flashing normal.

 I power cycled the radio and also rebooted my computer. I reconnected to the radio and it works fine on all bands but 15 meters. Whenever I switch to 15 meters, smartSDR crashes in the way described above.

Is it crashing during transmit? If so  I would suggest you have RF getting into the radio or RF getting into the network cable causing it to loose connection.
