FWA NATCA - I'm coming at this a couple of days late, but I'm interested in the concept of as many freqs as you guard all being stand alone (or did I miss somethng?)
In New Zealand, when we combine sectors or otherwise have to handle traffic over a wide area, we use a facility we call re-transmit where all the relevant freqs are combined and are retransmitted.
For example if 126.0 was for "North" and 123.7 was for "South", and the transmitters were geographically apart by say 300 miles, then a pilot transmitting on 123.7 would be re- broadcast on 126.0 by the ground equipment so everyone on 123.7 hears him. The controller goes out on all freqs simultaneously, and to a pilot on any of the selected freqs it sounds like just one is in use.
It may slow up the number of transmissions you can pack into an hour, but you don't have the problems of of the fliers not being aware of what is going on and getting on your case for not replying to them.
Cheers
