Radio was purchased 11/13/2017 and DX350 was purchased 3/19/2018. Took the radio out of the box when the amplifier arrived and verified the amplifier worked. Radio dead keys 4.5 watts and swings 15 RMS. Amplifier dead keys 210 watts and swings 300-310 RMS. Haven't used setup since and has been setting on my desk covered. New everything cost $400. Asking $300. Sellling as a set not separately. PM me here or email me.
