Looking at a hand-me-down circuit board that appears to be a RF detector function on a small double-sided circuit board. It has parts soldered onto it, but the main IC (marked C14 9CZ) is a mystery. Any guesses? Once IC is identified, can proceed with adding top/bottom via connections and power up the board. Thanks for any help! 73
