I have a question: Does anyone know what frequencies are used by the Super Shuttle from DIA? I have assumed they might've been in the 460-470 MHZ Range, on the business band sections of that slice of spectrum, but is there anyone here in Colorado that can confirm what I have just wrote? Or are their frequencies not listed at all here on RadioReference? I have traveled on the Super Shuttle Vans and know they operate Motorola radios and are on simplex from a base somewhere in Ft. Collins, but that's all I know. Furthermore are the frequencies they use analog, digital, or are they in encrypted mode? Any help would be appreciated. Thanks.
