-It would be a bit annoying to keep two different sets of settings (narrowband with 6.25 kHz VFO spacing for repeaters, and narrowband with 5 kHz VFO spacing for simplex).+It would be a bit annoying to keep two different sets of settings (FM-N with 6.25 kHz VFO spacing for repeaters, and regular FM with 5 kHz VFO spacing for simplex).
  
-The big issue for simplex is that, the national calling frequency would move to 146.525.  On a spreasheet, it's possible to fix the calling frequency to 146.520 and move 12.5 kHz away from there in both directions, however on my radio, when I set my VFO spacing to 6.25 kHz or 12.5 kHz, I hit 146.525 instead.  Many radios are also pre-programmed with a calling frequency button set to 145.520 so that would be a much bigger change.  Maybe this is one of the reasons that WWARA doesn't address simplex frequencies.+The big issue with re-channelizing the simplex frequencies is that, the national calling frequency would move to 146.525.  On a spreasheet, it's possible to pin the calling frequency to 146.520 and change all the other frequencies around it, however on my radio, when I set my VFO spacing to 6.25 kHz or 12.5 kHz, I can only select 146.525, not 146.520.  Many radios are also pre-programmed with a calling frequency button set to 145.520 so that would be a much bigger change.  Maybe this is one of the reasons that WWARA doesn't address simplex frequencies

 +In any case, this proposal seems to be moving ahead albeit very slowly.
