WebThe tone generator makes perfect tones, and it really doesn't matter how strong it is, how wrong it is or anything. I can shift the tone a herz or two in either direction and the repeater answers happily. I had simply forgot to use the right freqency to transmit..... Embarrasing. But SO HAPPY the tone generator and radio works. WebAnd my buddy down town says his Yaesu car radio also triggers perfecly with my CTCSS tone. A couple of repeaters up to 70km away also trigger nicely with my new signal. But our local repeater doesn't. I've got our local ham repeater just 1.5km up the street, with line of sight from my antenna. But that one doesn't trigger with my tone. laggan hotel cairngorms
