Sounds like the tone squelch isn't being broadcast constantly and your scanner is responding as it should in CTCSS mode, i.e. muting the audio when it doesn't see the tone. There could be several reasons that this is happening but if this is what is going on, then your scanner isn't broken. That's the good news. The bad news is, unless you leave it in Search mode, it's gonna keep cutting out on you.:twisted:
