I upgraded the other night to 2.3.9 and all was well. However, Wednesday morning when I booted up the rig and computer, all my saved profiles were gone. DAX is now not communicating with the radio and neither RX nor TX will go "Green" for on. Using the 6400M. Can anyone help me with this? Spent an hour trying to solve this problem. WSJT-X is set up correctly and passes the PTT and radio control tests, but no receive or transmit. Should I go back to an earlier version of SDR or what is going on?
