He must have been tuning while he was looking at an inverting linear transponder. That is, the downlink frequency goes up while the downlin frequency goes down as you tune across the passband. The doppler correction will always be in the same direction.

A buddy of mine just installed MacDoppler
It seems to work great but he sent me a video that doesn't make sense to me.
It is controlling his radio changing freqs as needed to account for Doppler. BUT... I have never seen this before.
the 144 band was changing one way in freq and the 440 band the other way. Huh? That doesn't seem right in my head.
anyone care to maybe explain whats happening?
