That probably wouldn’t help. In this case the system includes the SubRx, the Synthesizer and all the interconnects and cables that connect these to the rest of the radio.
I would check the interconnects, especially the tmp coax cables that go from the SubRx to the rear panel connector and to the Synthesizer. Also make sure the SubRx synthesizer is working properly. That might also explain the SubRx issue. 73!
