Spot on. It has to be full duplex for cross band repeat to work, whether 
the guys who write the manual, marketing literature, or QST review 
realize it.

I've never seen a radio advertised as full duplex, that wasn't. Even the 
G7 is, it just goes half-deaf. Non- full duplex rigs capable of 
reception of two bands at once are usually labeled as "dual receive".

Half-duplex is fine for getting your feet wet, but the increasing number 
of ops not moving up to full-duplex is having a real impact on the FM 
satellites over densely populated areas. Expense is no excuse. I've 
bought suitable uplink transmitters as cheap as $5 (IC-2AT), and the 
difference in an Arrow with and without diplexer is nearly the cost of a 
new simple 2m HT.
