Even at 500 kHz split, 100+ dB is more than enough isolation on channel
center on 6m. Using simple frequency scaling (not to say that's truly the
way to compare, but it gives a rough approximation), that would be like 1.4
MHz split on 2m with the same (100 dB) isolation. 500 kHz on 6m is about
0.9%, still more than twice as much as 0.4% on 2m with 600 kHz split.
