I am trying to run my 6400M remote and would like to use an LDG AT-600II. When I used this with an Icom radio I was able force the tuner into tune mode remotely by using the Icom interface cable. I know this tuner has a full auto mode but does not work as good as forcing it to tune. Can the Flex interface with LDG? I fear that tuning at power levels high enough to sometimes trigger the LDG could be harmful to the finals in the flex. Sometimes I need to use 50W before the mismatch is higher than 1.7. Not sure that I really want to be tuning with anymore that 10 watts. Thoughts ?
