Abstract

Many users of portable radios equipped with an external speaker/microphone utilize their radios as mobile or fixed stations by placing them in a vehicular charger or desk top charger with a remote antenna attached to the radio. A problem arises with this conliguration, where the battery capacity is depleted faster than it is supplied from the charger when the radio is operated with a high tmnsmit duty cycle. A means of offsetting the transmit current is needed to insure that the radio battery capacity is topped off. This is especially required when the radio is removed from the charger and is used as a portable.
