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
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.
