How can I legally make my VHF/UHF station into a crossband repeater?.
Modern dual-band or tri-band VHF/UHF rigs often have the capability to do crossband linking. When operating in this mode, the users may call them “crossband repeaters.” Actually they are often remote bases, such as when they are used to allow an operator with a hand-held radio to access a repeater from a location where he or she would normally not be able to do so. For example, a hiker in a remote location might leave his car where his dual-band mobile rig can access a distant 2-meter repeater. Leaving the mobile rig on, he then takes his UHF hand held with him, and can access the 2-meter repeater via his mobile rig. A crossband repeater (or “portable remote base”) is okay as long as several conditions are met: 1) The user communicates with his crossband rig via the UHF side. Since this serves as his control and voice uplink, it is a form of auxiliary operation and must be conducted above 222.15 MHz. Since the operator is the control operator, that person must actually be able to contr
