Flex 6700 all of a sudden started to step down the band on its own. Have not found a way to stop it and it will just continue to step down in Frequency . I have pulled the Flex Knob, that made no difference. Then I shut down the 6700 also with no change on the restart, then did a cold restart, still on restart it started to step again. My last attempt was a cold restart (shut down the 12 volt input power) and a reset to factory defaults, still no change. So I am going to bed and try again when I get up. Has anyone had this problem?
