Most radios have a bit higher distortion when using sync, plus there is
always going to be a slight frequency offset. Some radios will growl
trying to get the sycn. Throw the audio out on a spectrum analyzer and
you might spot a weak tone artifact due to the sync. Use it when it
sounds better, otherwise leave it off.

Sometimes there is more noise "under" one sideband than the other, so
you might use sync and pick the quieter sideband. Adjacent channel
splatter would be a good example of noise under one sideband and not
the other.

I probably use sync a few percent of the time.


I still don't under why Lowe used even implemented double sideband sync in
the HF-150 if it doesn't do anything over single sync. Why add this feature?
For what kind of scenerios??
