Accordingly, if your neighbor decides to build a new garage, it would be OK 
to build it on your property as long as one edge of the garage is on the 
property line?  I don't think you would be so happy with that 
interpretation. Similarly, I'm sure your reading of the rules will be a 
surprise to members of other radio services that use channels just outside 
the amateur allocations.  You might want to check with them!

Regardless, the FCC rules for US amateurs are explicit and clear.  Our 
sidebands (those greater than 27 dB below the mean power of the emission per 
the definition of bandwidth in Part 97.3) are *required* to be entirely 
*within* the US amateur phone allocations.  It is OK for non-US amateurs to 
call CQ with their LSB carrier on 7.125 MHz or a USB carrier on 14.350 MHz, 
but US stations are NOT permitted to answer them and do so at the risk being 
cited for out-of-band operation.
