Used to be that 27mhz radios were scarce, but lately, with the influx of all the RTR's, which are always on that band, they may not be that easy to get track time with.
Plus I think that the Japanese radio frequencies are compatible with our 27 mhz. bands.
Everywhere outside of the US (at least to my knowledge) has 12 channels for the 27mhz band. In the US it is obviously limited to just 6 channels. And yes, 27 mhz is supposed to be less susceptible to glitching from the likes of chain-link fences and pagers (or some stuff like that). Plus, in the US, the spacing between the channels on the 27 mhz band is 40 (something or other) while the spacing between channels on 75 mhz is 20 (something or other) so a badly tuned radio is less likely to cause glitching on an adjacent radio frequency on channel 27 as it is on channel 75.
Truthfully, the differences are negligible, and having more availible channels on 75 mhz band is advantageous. Its not like anyone really
complains about the performance of their radio because it runs on 75mhz as opposed to 27 mhz.
