They're VHF with the exception of the first one (462.725), which is UHF. BUT, all of them, although they are VHF/UHF frequencies, are not within the frequency range of the government-prescribed ham 2-meter band, which runs from 144 to 148 MHz in North America. On most amateur band (ham) dual radios the "dual" refers to two bands: 1) the 2 meter band, which is 144-148 MHz, and the 70 centimeter band, which is 420-450 MHz. So, none of those channels listed on the "Rugged Ridge" spreadsheet correlate with traditional ham bands. Although some radios will tune to those frequencies (my cheap Baofeng handheld for instance), operating on those frequencies without appropriate licensing is technically illegal - at least from an amateur radio standpoint. This is one of the reasons the FCC has threatened to crack down on the import of these cheap, Chinese *ham* radios, be they Baofeng, BTech, TYT or any of a myriad of Chinese radios.
IF you were to purchase a true dual band radio from one of the traditional (law-abiding and reliable) manufacturers such as iCOM, Yaesu, Kenwood, etc., they would only accommodate the frequency range I've described above. Therefore, anyone who is running a true *ham* dual band radio would not be able to tune to the frequencies listed on the Rugged Ridge spreadsheet.
