Nate, I'll preface this by stating that I'm the repeater coordinator for Montana, and a retired career 2-way radio tech.
It's common for repeaters to require a CTCSS tone for access, but is -very- rare to find one in the amateur world that also transmits the CTCSS tone. Out of almost 300 I have in Montana I'm aware of none. The ARRL Repeater Directory lists the tone required if it's needed for accessing a repeater. Yes, one can listen to the station that's accessing the repeater and perhaps ascertain the frequency of the CTCSS tone, but this is difficult to do since the tones are in the sub - audible range. There -are- scanners and amateur transceivers that can do this and of course professional test equipment. BTW ... CTCSS stands for "Continuous Tone Coded Squelch System". The tones are standardized and are the same for all brands of 2-way radios but each has their own trade marked names ... (Motorola = PL / Private Line), GE = CG / Channel Guard), etc. A Google search will tell you more..... 73 Ken - K0PP ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
