Of course, on the Linear birds, IF you are running Full Duplex, you 
actually CAN talk over each other and still be understood.  On AO-40 (so 
doppler tracking wasn't a big problem) I would often just click in the 
MOX button on my rig.  If I don't say anything (and it's otherwise quiet 
in the shack), no RF goes out.  When I talk, it transmits.  Nice and 

But this only works with FDX, and only with SSB, and only if you have 
computer or physical (HEO) control of doppler.  Oh, and be careful not 
to wake up Leila when you both talk at the same time too often...  She 
considered it bad manners.
