Using CTCSS or DCS to filter traffic

[VK3TKO]

Thanks Doug. That's a very nice way of advising me to read the manual first. Good suggestion. You've also clarified my understanding of how a repeater works. Your point about transmitting over others is important. I expect to use my radio's monitor function before each call to open its audio to non-coded transmissions.
Time to hit the books.
