This type of thing is the reason that Analog FM coordinations in our area REQUIRE that the system have a working CTCSS decoder. It doesn't have to be ON all the time, but you must implement one in order to obtain a coordination. Complaints about co-channel interference during band openings from far-away repeaters are then met with, "Why didn't you turn on your decoder?" Especially complaints about UHF, where we're "upside down" from a couple of surrounding States. (We're high-out, low-in, some are the other way around, which makes things "interesting" along the borders.) Similarly, encoders at the repeater and CTCSS "squelch" on user radios will alleviate the situation where a band opening carries a far-away repeater's output to your users. As the joke goes around here... "Time to implement that 1970's technology!" Nate WY0X
