Well, sorry but *WRONG!!!*. 1200 packet mode rolls off the
low side of the audio spectrum and makes CTCSS decoding completely
impossible. Its not too happy with the high side of the spectrum
and the squelch detection either. Thats why I was forced to use
9600 and having to give it a signal higher then the Alps.

I dont know why the radio is so hard-of-hearing at 9600 baud,
but thats Kenwood for you. You will also need the "txboost=y"
in the usbradio.conf (and the latest version of software that
supports it).
