One of the things that I'm having trouble sourcing is which repeaters are enabled for CTCSS. I know for example that VK6RVP and VK6RUF both require a 123Hz tone before they will open up the squelch, but I believe that other repeaters are what you might call "CTCSS Optional" - i.e. they don't require a tone to be sent on the input, but the repeater itself will put out a tone on it's output.
That's handy for people like myself who have to transit the city and can get bombarded with pagers or LIPDs - we can set the radios to require tone on receive, but people talking into the repeater don't necessarily need a CTCSS-enabled radio themselves.
I wonder ... does anyone know for sure which repeaters do or don't have CTCSS - either as an option or as a requirement? I'm planning on doing it the hard way tonight and just listening on various repeaters both with and without tone and see if I can figure it out that way - but if someone has a list that could save me some work, that'd be even better
