Yeah, but it isn't full duplex.  When it is transmitting, it isn't listening
on the up freq.  So it might as well have been a collision because the radio
didn't hear it.

     Cuts the traffic (and hence the probability of colliding packets) in 
half.  I would think the "hidden transmitter syndrome" is greatly enhanced 
when trying to work a moving target with just a 12-15 minute window.  Split 
operation helps this.
