I sent my 6600M for repair as it crashes about once a day. Steve says it must be something in my shack. My 6700 and 6500 have never crashed and they are hooked up exactly the same way and using the same cables as the 6600M. The 6600M arrived back here yesterday and it has crashed twice already. There were no power fluctuations and it was receiving at the time so no rf. I am running v18.104.22.168 Am I the only one that is having this problem?
