Hi Jim, Thanks for that, I have no experience of DCS other than using it on my "black box" amateur sets.
My time in the PMR trade was served before it ever made it over here! Thanks for the info - looks like its needed to have either one or the other I guess, depending on which method the user has used to access the repeater.

If I set the tone to 700hz dev, when I started turning up the DCS level, just about the point where it would start decoding, tone would stop decoding, and vice-versa. I couldn't find a level that would allow both to decode, it was always one or the other. And bear in mind, this was using the near perfect modulation of the wavetek service monitor. Getting a normal radio to generate that clean a waveform, especially DCS, is rare. You can try it, but I have my doubts that it will work. -- Jim Barbour WD8CHL Yahoo! Groups Links Yahoo!
