摘要: A communication device (105) includes a first communication block (205) for operation within a first communication network (150); and a second communication block (210) for operation within a second communication network (160). The communication device (105) further includes an audio control (245) for at least one microphone (250). The audio control (245) is coupled to the first communication block (205) for receiving a first audio input for operation of the first communication block (205) and is coupled to the second communication block (210) for receiving a second audio input for operation of the second communication block (210). A low noise ground (315) is isolated from a common ground (320) of the communication device (105) to facilitate the sharing of the at least one microphone (250) between the two communication blocks.

摘要: A communication device (105,200) includes a cordless telephone (205) and a two way radio (210). The communication device (105,200) is adapted to place an active cordless telephone call in a low frequency mode in response to receiving an incoming two way radio communication. The communication device (105,200) is adapted to then establish communication within the two way radio communication. The communication device (105,200) periodically re-establishes the cordless telephone call to maintain communication with a cordless base station (120) until the two way radio communication is completed.

摘要: A receiver (10) includes an antenna (12), a preselector (14), an amplifier (16), a mixer (18), a filter (20), a signal strength measurement circuit (22), a radio frequency signal detector (26), and a processor (24). The processor (24) is programmed to receive a signal indicator level (42) from the signal strength measurement circuit (22), generate an automatic gain control command (44) based on the received signal indicator level (42), and send the automatic gain control command (44) to the amplifier (16) to control a gain of the amplifier (16). The processor (24) is programmed to receive an off channel signal strength (48) from the radio frequency signal detector (26), compare the off channel signal strength (48) to one or more threshold levels, generate a filter command (46), and send the filter command (46) to the filter (20). The filter command (46) identifies a cutoff frequency for the filter (20).
