The Baofeng 2m/220 dual band handheld radios
When deciding on the right Baofeng radio to choose from, it really comes down to a matter of preference. All the Baofeng UV-5R series of radios are the exact same thing, except for a few minor firmware versions, they can all be programmed by a USB computer cable.
The only difference that I know of are the Baofeng UV-5RAX/RCX radios that are 2M/220 versions. These are programmed at the baofeng factory and are only available at Radio Mart at this time. I have never had any affiliation with Radio Mart and have never made any purchases through this company.
The Baofeng UV-RCX is NOT a modification to existing 2m/440 versions, but a factory made version. Sure most of the Baofeng radios out their can be modified to receive in the 220 range but the performance and receive are very poor and the modified radios will not transmit.
The Baofeng UV-5RAX is the same as a UV-5RXC with 2M/220 capabilities. Again the only difference between the 2M/220 dual band handheld radios is the cosmetics.
Great prices on the Baofeng UV-5R at Amazon
