I have a Flex 6300 without a built-in tuner and it will tune into a dummy load without any problems on all other bands except on 40M where it give very high SWR and no output power.  All other bands work as expected. 10W and SWR less than 1.5.  Does it need a trip to Austin or am I doing something silly?
During normal operation I use an external KAT500. This is the first time I have tried to use 40M as I did not have an antenna that was capable of 40M.
