[amsat-bb] Mac Doppler

[Joe]

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?
