It seems to me that if you have all the repeaters in an area running the same CTCSS tone, and start fighting a mixing problem... everything is going to be back to keying everything else in short order. Out here, whether by design or by mistake -- I don't know which, it was all before my time -- the different large clubs all ended up using their own tones for their repeaters... Our club is 107.2, another large club is 103.5, the statewide linking system is 123.0, a couple of smaller clubs use 100.0... No one's the same, all require tone to access the repeater in almost all cases (there are a few die-hards with CSQ repeaters, but most have had to use controllers that have "anti-kerchunk" features to keep the noise/crud out), and not to many folks complained -- after the initial whining when most of the clubs moved "together" to require CTCSS, years ago.
