Narrative:

During climb out on vectors, assigned altitude 8000 ft, ATC advised our flight that unconfirmed 7500 ft VFR traffic was at our 11:30 O'clock for 3 mi. Simultaneously our TCASII issued a TA. Our flight was passing 6800 ft in a 1200 FPM climb at 200 plus KIAS. The captain (PNF) visually acquired the traffic and ordered 'level off.' our aircraft leveled at 7200 ft and immediately descended back to 7000 ft. As we passed 7100 ft MSL the conflicting aircraft passed directly overhead about 300-500 ft above us. He gave no indication of having seen our aircraft. The conflict aircraft was a yellow/white bonanza V35. Only sun angle and closure rate prevent me from reporting the registration number. Cvg should be class B airspace. Every day that is delayed brings us one day closer to a repeat of san diego or la!

Title: E120 ON VECTORS CLBING 8000 FT. TFC CALLED BY DEP CTLR UNCONFIRMED AT 7500 FT. TCASII TA AND TFC SIGHTED. BEGAN A LEVEL OFF AT 7200 FT AND B35 PASSED DIRECTLY OVERHEAD AT 7500 FT. NO EVASIVE ACTION TAKEN BY B35.

Narrative: DURING CLBOUT ON VECTORS, ASSIGNED ALT 8000 FT, ATC ADVISED OUR FLT THAT UNCONFIRMED 7500 FT VFR TFC WAS AT OUR 11:30 O'CLOCK FOR 3 MI. SIMULTANEOUSLY OUR TCASII ISSUED A TA. OUR FLT WAS PASSING 6800 FT IN A 1200 FPM CLB AT 200 PLUS KIAS. THE CAPT (PNF) VISUALLY ACQUIRED THE TFC AND ORDERED 'LEVEL OFF.' OUR ACFT LEVELED AT 7200 FT AND IMMEDIATELY DSNDED BACK TO 7000 FT. AS WE PASSED 7100 FT MSL THE CONFLICTING ACFT PASSED DIRECTLY OVERHEAD ABOUT 300-500 FT ABOVE US. HE GAVE NO INDICATION OF HAVING SEEN OUR ACFT. THE CONFLICT ACFT WAS A YELLOW/WHITE BONANZA V35. ONLY SUN ANGLE AND CLOSURE RATE PREVENT ME FROM RPTING THE REGISTRATION NUMBER. CVG SHOULD BE CLASS B AIRSPACE. EVERY DAY THAT IS DELAYED BRINGS US ONE DAY CLOSER TO A REPEAT OF SAN DIEGO OR LA!
