TRIO KT-990 with Analog Meters AM/FM Radio Tuner - Brand: TRIO - Model: KT-990 - Function: AM/FM Radio Tuner Receiving signal confirmed from a wall-mounted TV antenna. When tuning, turn the dial while watching the red and orange levels on the triangular meter. Release the dial when the signal level is high, and the servo lock will engage. I don't listen to AM, so I don't know about that. Thank you for looking.
