by the transceiver to provide the user with an alert in the event an inappropriate battery pack antenna is being used the information may also be used to modify the normal operation of the transceiver to avoid possible damage application_number US 59674884 A description turning now to fig1 a transceiver system 10 embodying one form of the present invention is shown system 10 includes a receiver 12 and a transmitter 14 both of which are coupled to an antenna switch 16 which is used to selectively couple either receiver 12 or transmitter 14 to an antenna 18 according to whether the transceiver system 10 is in the transmit or receive mode as is well known in the art in the preferred embodiment antenna 18 is disposed within a removable battery enclosure 20 shown in broken lines in fig1 an electrical battery 22 is also disposed within battery enclosure 20 so that battery enclosure 20 forms the enclosure of a combination battery pack antenna electrical battery 22 includes a positive electrode 24 and a negative electrode 26 negative electrode 26 normally forms the ground potential for the transceiver and is coupled to a negative terminal 28 of the battery enclosure 20 positive electrode 24 may be coupled to a positive battery terminal 30 through a small current limiting resistor 32 battery power is then supplied to the transceiver system via terminals 28 and 30 when the battery pack antenna is coupled to the remainder of the transceiver it may be desirable in some instances to condition the battery voltage in.
