Well -- in the system I originally described, the paging tones went
out over the output of an already-extant repeater. No additional
frequency was needed.
The same thing could be done with this idea -- either on 144.39 (us)
or -- uh -- what is it in the UK??? Anyway, it could work on the same
frequency as AX.25 APRS, and probably wouldn't cause much problem with
congestion, or on a voice repeater with a slight equipment/software
addition. No additional frequencies are REQUIRED, although it certainly
would be nice.
