Yesterday John K ask a question about using a high power supply with his flexRadio. The question got me thinking about how the 6400 and other flexRaios are designed. Without a schematic (which must be old school now) I don’t know if these radios have a common chasse ground or a floating system ground.
Which makes me wonder if both the negative and positive power leads should be fuse at 30 amps, and a non-fused earth ground to the radio chassis.
I am assuming that if both positive and negative power leads needed to be fused that flexRadio would have done so. I do wonder because I know many cost saving deviations have been incorporated in the new 6400. What would be best practice for our power leads and are fuse additions necessary?
