Zero beating may not be "the" answer in all cases, keep in mind that some 
operate with a shift to reject local QRM which you may not hear. Something to 
keep in mind when wondering why they don't hear you where you think they should.

Another possibility is that they may have forgot to shut off their RIT/XIT.

Keep flexible is the best advice.

Cheers,
Julius
