Narrative:

Aircraft X departs jyo filed over wooly at 5000 ft. The aircraft never checked on after noticing airborne. After several attempts; I finally established 2-WAY communications with him. I first had the aircraft identify and climb to 7000 ft expeditiously. I then turned the aircraft to a 100 degree heading shortly thereafter; following coordination with the controller in charge; I reissued 3000 ft and a 090 degree heading; to which he failed to respond. I then gave him a frequency change to 126.1 to which he responded. Supplemental information from acn 668759: it was coordination for me to receive aircraft X at 3000 ft on a 90 degree heading. The aircraft was issued this but did not read it back. The aircraft checked in leaving 3000 ft for 7000 ft; but I did not hear him -- sector was busy. He checked in again and I acknowledged. I planned traffic for this aircraft (who was leaving 4000 ft for what I now expected to be 5000 ft; his filed requested altitude) to go on course at 5000 ft; under my traffic at 6000 ft. I turned aircraft X north to get behind traffic already at 5000 ft. When clear; I turned aircraft X on course; still expecting him to level at 5000 ft. He climbed to 5400 ft. I called traffic and descended him immediately to 5000 ft; as he was now an issue for my 6000 ft traffic. When he was clear; I handed him to the next sector.

Title: 2 PCT CTLRS DESCRIBE OPERROR AT APPROX 5400 FT AS READBACK FAILURES AND POSSIBLE ACFT RADIO PROBS CONTRIBUTE.

Narrative: ACFT X DEPARTS JYO FILED OVER WOOLY AT 5000 FT. THE ACFT NEVER CHKED ON AFTER NOTICING AIRBORNE. AFTER SEVERAL ATTEMPTS; I FINALLY ESTABLISHED 2-WAY COMS WITH HIM. I FIRST HAD THE ACFT IDENT AND CLB TO 7000 FT EXPEDITIOUSLY. I THEN TURNED THE ACFT TO A 100 DEG HDG SHORTLY THEREAFTER; FOLLOWING COORD WITH THE CIC; I REISSUED 3000 FT AND A 090 DEG HDG; TO WHICH HE FAILED TO RESPOND. I THEN GAVE HIM A FREQ CHANGE TO 126.1 TO WHICH HE RESPONDED. SUPPLEMENTAL INFO FROM ACN 668759: IT WAS COORD FOR ME TO RECEIVE ACFT X AT 3000 FT ON A 90 DEG HDG. THE ACFT WAS ISSUED THIS BUT DID NOT READ IT BACK. THE ACFT CHKED IN LEAVING 3000 FT FOR 7000 FT; BUT I DID NOT HEAR HIM -- SECTOR WAS BUSY. HE CHKED IN AGAIN AND I ACKNOWLEDGED. I PLANNED TFC FOR THIS ACFT (WHO WAS LEAVING 4000 FT FOR WHAT I NOW EXPECTED TO BE 5000 FT; HIS FILED REQUESTED ALT) TO GO ON COURSE AT 5000 FT; UNDER MY TFC AT 6000 FT. I TURNED ACFT X N TO GET BEHIND TFC ALREADY AT 5000 FT. WHEN CLR; I TURNED ACFT X ON COURSE; STILL EXPECTING HIM TO LEVEL AT 5000 FT. HE CLBED TO 5400 FT. I CALLED TFC AND DSNDED HIM IMMEDIATELY TO 5000 FT; AS HE WAS NOW AN ISSUE FOR MY 6000 FT TFC. WHEN HE WAS CLR; I HANDED HIM TO THE NEXT SECTOR.
