RPTR LANDED GEAR UP.

Narrative

I JUST PURCHASED A MOONEY M-20F (68). MY TOTAL TIME; EXCEPT RECENT 10.2 HRS OF DUAL IN THIS PLANE; WAS IN CESSNA 172. I WAS DOING TOUCH-AND-GOES AT PELION CORPORATE ARPT AND HAD EXECUTED MY TOUCH-AND-GO AND PUT GEAR UP AND THEN CAME AROUND PATTERN AND LOWERED GEAR AND CAME TO FULL STOP. I THEN TAXIED TO RWY 17 AND TOOK OFF AND PUT GEAR UP. I TUNED IN ATIS ON #2 COM (HAD BEEN TALKING UNICOM 122.7) AND COULD NOT GET THE RADIOS TUNED CORRECTLY. I WAS HEARING ATIS ON #1 AND YET IT (KNOB) WAS ON #2. I WENT THROUGH LNDG CHK AND VISUALLY THOUGHT MY GEAR WAS DOWN. MY MIND WAS PREOCCUPIED; I BELIEVE; WITH ATIS AND IT DID NOT REGISTER. (I HAD NO LIGHT AND THE STICK WAS DOWN ON MANUAL LNDG GEAR. GEAR DOWN -- STICK UP -- GEAR UP -- STICK DOWN.) THIS WAS A CARELESS MISTAKE AND I HAVE CHKLIST PASTED ON PANEL IN FRONT PLUS I TRY TO USE GUMP. I WAS NOT CONCENTRATING AS I SHOULD HAVE AND MY VISUAL CUES DID NOT REGISTER WITH MY MIND. IT WAS A MISTAKE AND THANKFULLY; NO ONE OR NOTHING WAS DAMAGED EXCEPT MY EGO AND PLANE. NO DAMAGE TO RWY OR ARPT. WE JACKED PLANE; EXTENDED GEAR; AND PUSHED IT TO THE HANGAR
