If you truly have programmed the radio with Tone set to 67.0 then it
should show up as 67.0 in menu 13 (T-CTCS). as 67.0. If not, do it
again. When using Windows you not only have to select 67.0 in the drop
down menu, you have to press enter or click onto another cell to make
the selection "stick" (this extra step isn't needed for Linux or Mac
OS X).

If T-CTCS is set to 67.0 then I would expect that 67.0 is not the
required tone. You can use the tone scan feature of the UV-5R to
determine what the CTCSS tone of the Motorola radio is.
