Yes. And it doesn't even NEED band data -- like the KPA500, it 
auto-detects the transmiitted frequency, recalls settings for that 
frequency, and switches between antennas if it has been programmed to do 
so.  I've been beta-testing one for about a month. The only connections 
between my K3, KPA500, and KAT500 are coax and PTT, and they work 
together flawlessly.  When I do contesting, I use the K3 and KAT500 with 
my 30 year old Ten Tec Titan tube amp at legal limit power. Works fine 
that way too.

A band data connection allows the KAT500 to switch when you change bands 
on the K3, before you transmit. That saves a few hundred msec.  So far, 
I've not seen the need for it.
