1. An HF radio transceiver apparatus, comprising:
- antenna means;
a programmable controller having a plurality of control signals;
a plurality of receivers, connected to the antenna means, each receiving and demodulating radio signals transmitted from external radios, in common or mutually exclusive communication modes, and providing link-data information to the programmable controller;
a transmitter, responsive to the programmable controller and coupled to the antenna means, for transmitting modulated data in at least one of the common or mutually exclusive communication modes; and
the programmable controller commanding the plurality of receivers such that one of the receivers paired with the transmitter and operating in one of the communication modes is used to maintain a communication link for a substantial period of time and, in response to a communication link outage, a second receiver is paired with the transmitter operating in a second communication mode to reestablish the failed communication link.

Abstract
An HF radio transceiving apparatus that maintains communication integrity by employing a plurality of receivers, each capable of operating in separate and independent communication modes. One embodiment of the apparatus includes an antenna, a programmed controller having a plurality of control signals, first and second receivers and a transmitter section. The receivers receive and demodulate radio signals transmitted from external radios in common or mutually exclusive communication modes, and provide link-data information to the programmed controller. The transmitter, responsive to the programmed controller and coupled to the antenna, transmits modulated data in one of the common or mutually exclusive communication modes. The controller commands the first and second receivers and the transmitter such that the transmitter is dynamically paired with the appropriate receiver for operation in the desired communications mode as determined manually by the operator or by an appropriate automatic communications protocol.

7. An HF radio transceiver apparatus, comprising:
-
antenna means; a programmable controller having a plurality of control signals; a first receiver and a second receiver receiving modulated data from said antenna means, said first and second receivers each receiving and demodulating radio signals transmitted from external radios in mutually exclusive communication modes and providing link-data information to the programmable controller; a transmitter, responsive to the programmable controller, and coupled to the antenna means, for transmitting modulated data in one of two mutually exclusive communication modes; and said programmable controller commanding the first and second receivers such that one of the receivers is paired with the transmitter, operating in one of said communication modes, is used to maintain a communication link for a substantial period of time and, in response to an incoming call received by the second receiver operating in the other of said communication modes, the second receiver, providing link data to the controller, causes the maintained link to be interrupted, the transmitter to be paired with the second receiver, and the incoming call established as a priority communications link. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. An HF radio transceiver apparatus, comprising:
-
antenna means; a programmable controller having a plurality of control signals; a plurality of receivers, each receiving and demodulating radio signals transmitted from external radios in mutually exclusive communication modes, and providing link-data information to the programmable controller; a transmitter, responsive to the programmable controller and coupled to the antenna means, for transmitting modulated data in one of said mutually exclusive communication modes; and said controller, monitoring the receivers, and detecting predetermined signals from one of the receivers via the link data from said receiver, pairs the transmitter for operation with said receiver to respond appropriately according to a predetermined link protocol in one of the communication modes. - View Dependent Claims (15, 16, 17, 18, 19, 20)
