Wait a minute...  How can a radio be capable of cross-band repeat and not be full duplex?  I believe the answer is no.  Cross-band (analog) repeating is inherently full duplex.  So, perhaps this is a simple way to ask a non-satellite person, without having to explain what duplex means.

By the way, my Alinco DR-610 mobile rig is also full-duplex.  You may add it to the list.  (In fact, it's got some down-right-weird modes, between the two sides of the radio, that it's sometimes anyone's guess what will happen when you key up.)
