This is a direct replacement for later model SR-447HPC / SR-497HPC 10 Meter Radios. You can substitute this board for the larger echo board used on earlier SR-440HP, SR-490HP, SR-447HPC & SR-497HPC. Some connectors on those radios might be different, so you will need some basic troubleshooting skills to substitute it for the larger board.
