Systems and methods for seamless switching of default data radio

A communications management system, comprising:

• a first input configured to be communicatively coupled to a first data radio and a first antenna via the first data radio, wherein the first input is configured to transmit and receive datalink communications only via the first data radio and the first antenna;
• a second input configured to be communicatively coupled to a second data radio and a second antenna via the second data radio, wherein the second input is configured transmit and receive datalink communications only via the second data radio and the second antenna, wherein the first data radio and the second data radio are tuned to the same frequency for data communications;
• and
• at least one processor communicatively coupled to a memory, the first input, and the second input, wherein the at least one processor is configured to:
• monitor one or more parameters for the first data radio coupled to a first antenna and one or more parameters for the second data radio coupled to a second antenna;
• compare the one or more parameters for the first data radio with the one or more parameters for the second data radio;
• determine whether the first data radio or the second data radio has better current performance based on the comparison of the one or more parameters for the first data radio with the one or more parameters for the second data radio;
• in response to a determination that the first data radio has better current performance, switch to or maintain the first data radio for primary data communications where only the first data radio is used to transmit downlink data communications and both the first data radio and the second data radio are used to receive uplink data communications at the same time;
• and
• in response to a determination that the second data radio has better current performance, switch to or maintain the second data radio for primary data communications where only the second data radio is used to transmit downlink data communications and both the first data radio and the second data radio are used to receive uplink data communications at the same time.

• comparing the one or more parameters for the first data radio and the one or more parameters for the second data radio;
• determining whether the first data radio or the second data radio has better current performance based on the comparison of the one or more parameters for the first data radio and the one or more parameters for the second data radio;
• and
• switching from the first data radio to the second data radio for primary data communications in response to a determination that the second data radio has better current performance.
