[DEMI] TRS?

[kf0q@arrl.net]

I would like to talk to someone who is currently using a TRS.  All of 
my microwave transverters (902,1296,2304)  have a common IF 
which is really nice and simple.  I do however have some issues 
with keying all three transverters individually, (using 290RII w/ TTL 
or the IF radio) that make things a bit chunky during a contest.  I 
am thinking about perhaps adding a 4th microwave band and 
wonder if I should consider a TRS (or some type of sequencer -) 
especially if the PTT issue would improve.  Any information 
appreciated.
