I have TONS of problems on 27 mghz here in Las Vegas.. in Branson Mo I was able to run my 27 stuff with no problems at all. and the Megatech that is on channel "4" is the bad one here glitchs constantly but the best Channel is "2" the chicago I have is very uncontrollable but my Dallas is very nice and enjoyable to mess with. both are the same channel frequency. I think in the heavier populated areas like Vegas I would agree that 27 is BUSY!!! and CBs are in that wavelength I thnk between 26 and 27 FM or AM if AM then the CB thing would make the most scense being that alot of people run linears and crap so that things will bleed over to 27 I would think,, and being that there are more and more and more truckers out there that would defenatly increase the CB usage in the bigger areas.
