A hardware timer circuit connected to a radio's main power would allow the radio to be powered up periodically when the physical power switch is in the off position. This timer with the addition of some software and a hardware line connected to an I/O port on the radio's main processor would allow a system access to a radio and its features, such as Radio Inhibit, with a minimum of current loss at any time a good battery was connected to the radio and the radio was in range of a system.
