A system and method are provided for preventing lapses of communication in radio voice communications. The system may include a communications transceiver for transmitting signals through a communications antenna. A protection antenna, which may be isolated from the communications antenna, may obtain a received signal from a remote transmitter. The received signal may contain a signal of interest that may be combined with interference from the communications the communications transceiver. A protection receiver, coupled to the protection antenna, may obtain a sample of a transmit signal from the communications transceiver. Using the sample of this transmit signal, the protection receiver may remove the interference from the received signal to obtain the signal of interest. If it is determined that a communications channel is blocked, the protection receiver may store the transmit signal and later retransmit the stored transmit signal when the communication channel is unblocked.
