You could set it up so that the 100hz decoder didn't enable repeat...
This would encourage the folks to dial up the correct tone...
Just wire the 100hz decoder's output to a digital input on the controller,
and program it so that when that input goes from active to inactive
the controller says "Welcome to the area - the PL tone on the
(insert callsign here) repeater is 131.8hz".
Or if your thinking is to use minimal airtime, just say "Use 131.8hz"
