Narrative:

I bought a bonanza S-35 small aircraft X in newton, ks, and I flew the airplane from newton, ks, to greenwood, sc. I filed an IFR flight plan to greenwood, sc (grd) in 2 parts. The first leg started at newton (ewk, cnu, eos, flp, jbr, mkl). As I was taxiing to runway 20, I could not get a response on the radio, and aborted the planned flight. After returning to the operation were I purchased the airplane, we determined that the left hand jack was out of order, but the right hand jack worked okay. We talked to the tower and everything seemed to be in order. I taxied back to the active runway and received my clearance to grd at 7000 ft. Shortly after leveling off at my assigned altitude of 7000 ft, wichita departure handed me off to ZKC. After about 10 mins with kansas city, I thought that I heard my call sign and was asked if I could accept 9000 ft. I promptly replied X could accept 9000 ft and started my climb form 7000 ft to my new altitude of 9000 ft. If the kansas city controller contested my reply, I never heard her, the radios, had a screech in them from the time I departed and I was never able to correct the problem. About the time I leveled off at 9000 ft, I heard air carrier Y pilot talking to ZKC about a plane in their airspace. At this time I was in VFR conditions, I am sure air carrier Y pilot was referring to my plane. I never saw Y as they were above and to my rear. Sometime later ZKC handed me off to another controller and I was instructed to descend to 7000 ft and I promptly did so and remained at 7000 ft for the duration of the flight. The screech and noise never improved in my headset for the remainder of the flight. Supplemental information from acn 272381: a bonanza filed ewk to cnu and points beyond is assigned 7000 ft. A beoz filed ict to emp and points beyond is assigned 9000. Both are given their altitude by wichita approach. Hut radar is OTS and the bonanza's mode C is intermittent. Conflict alert goes off when the bonanza is behind the beoz. Altitude readout shows 8500. Bonanza is asked his altitude, he say 8700. Bonanza is told to descend to 7000. Beoz is told to climb to 10000.

Title: SMA X UNAUTH CLB FROM ASSIGNED ALT HAD LTSS FROM ACR Y. PLTDEV.

Narrative: I BOUGHT A BONANZA S-35 SMA X IN NEWTON, KS, AND I FLEW THE AIRPLANE FROM NEWTON, KS, TO GREENWOOD, SC. I FILED AN IFR FLT PLAN TO GREENWOOD, SC (GRD) IN 2 PARTS. THE FIRST LEG STARTED AT NEWTON (EWK, CNU, EOS, FLP, JBR, MKL). AS I WAS TAXIING TO RWY 20, I COULD NOT GET A RESPONSE ON THE RADIO, AND ABORTED THE PLANNED FLT. AFTER RETURNING TO THE OP WERE I PURCHASED THE AIRPLANE, WE DETERMINED THAT THE L HAND JACK WAS OUT OF ORDER, BUT THE R HAND JACK WORKED OKAY. WE TALKED TO THE TWR AND EVERYTHING SEEMED TO BE IN ORDER. I TAXIED BACK TO THE ACTIVE RWY AND RECEIVED MY CLRNC TO GRD AT 7000 FT. SHORTLY AFTER LEVELING OFF AT MY ASSIGNED ALT OF 7000 FT, WICHITA DEP HANDED ME OFF TO ZKC. AFTER ABOUT 10 MINS WITH KANSAS CITY, I THOUGHT THAT I HEARD MY CALL SIGN AND WAS ASKED IF I COULD ACCEPT 9000 FT. I PROMPTLY REPLIED X COULD ACCEPT 9000 FT AND STARTED MY CLB FORM 7000 FT TO MY NEW ALT OF 9000 FT. IF THE KANSAS CITY CTLR CONTESTED MY REPLY, I NEVER HEARD HER, THE RADIOS, HAD A SCREECH IN THEM FROM THE TIME I DEPARTED AND I WAS NEVER ABLE TO CORRECT THE PROB. ABOUT THE TIME I LEVELED OFF AT 9000 FT, I HEARD ACR Y PLT TALKING TO ZKC ABOUT A PLANE IN THEIR AIRSPACE. AT THIS TIME I WAS IN VFR CONDITIONS, I AM SURE ACR Y PLT WAS REFERRING TO MY PLANE. I NEVER SAW Y AS THEY WERE ABOVE AND TO MY REAR. SOMETIME LATER ZKC HANDED ME OFF TO ANOTHER CTLR AND I WAS INSTRUCTED TO DSND TO 7000 FT AND I PROMPTLY DID SO AND REMAINED AT 7000 FT FOR THE DURATION OF THE FLT. THE SCREECH AND NOISE NEVER IMPROVED IN MY HEADSET FOR THE REMAINDER OF THE FLT. SUPPLEMENTAL INFO FROM ACN 272381: A BONANZA FILED EWK TO CNU AND POINTS BEYOND IS ASSIGNED 7000 FT. A BEOZ FILED ICT TO EMP AND POINTS BEYOND IS ASSIGNED 9000. BOTH ARE GIVEN THEIR ALT BY WICHITA APCH. HUT RADAR IS OTS AND THE BONANZA'S MODE C IS INTERMITTENT. CONFLICT ALERT GOES OFF WHEN THE BONANZA IS BEHIND THE BEOZ. ALT READOUT SHOWS 8500. BONANZA IS ASKED HIS ALT, HE SAY 8700. BONANZA IS TOLD TO DSND TO 7000. BEOZ IS TOLD TO CLB TO 10000.
