Abstract
A system and method to eliminate the squelch-tail in radio receivers used for data communications. The transmitter adds a brief period of unmodulated carrier signal to the end of each data transmission. A sensor in the receiver detects this period and mutes the output of the receiver before the receiver's normal noise sensing circuitry senses that the transmission has ended. A circuit may be added to the transmitter to correct the last data bit sent in the data transmission.
