Narrative:
Atx X contacted cha approach approximately 30 DME from the cha VOR at 11000 ft. Cha gave us 7000 ft and shortly thereafter, a 070 degree heading for the visual for runway 20. At this time, we heard a baron request runway 33 and then ask if it would be a problem. Approach answered in the negative. Approximately 12 mi from the airport, the first officer requested lower and we were given 4000 ft. At approximately 7 mi from the airport, still on the 070 degree heading, cha gave us 3500 ft and the first officer called the airport in sight. Approach control cleared us for the visual approach for runway 20 and shortly afterwards, handed us off to tower. When we switched to tower frequency, we overheard tower tell the baron to turn his base leg now. The first officer checked with tower for the visual runway 20 and we were told we were #2 behind a baron on the approach for runway 33, a crossing runway. The first officer replied that we would slow it down as best we could. At approximately 500 ft AGL, tower said, 'this isn't working out,' and instructed us to 'start a climbing right turn.' we were not told to go around. Tower then seemed to forget about us. After climbing for about 1600 ft in a slow right turn, climbing through 3100 ft MSL, and a heading of 250 degrees, I requested a heading and altitude. We were given 3500 ft and a heading of 250 degrees. We then started getting vectors of about 30 degrees heading change for each vector until we were roughly paralleling runway 2-20 on an approximately heading of 330 degrees. Shortly after getting the vector of 330 degrees, we were given traffic Y at 1 O'clock and less than a mi. I spotted a cessna 210 at 1 O'clock at approximately 1/4 to 1/2 mi and 300 ft. I pitched up and the cessna passed directly below us. I pointed out the cessna to the first officer and he reported it in sight. We were told to maintain visual separation and given 2500 ft. We then followed a sabre jet for the visual runway 20, normal approach and landing. The saab sf-340B I fly is a 30 passenger, part 135 aircraft with no TCASII.

Title: ATX X HAD NMAC LTSS FROM Y. SYS ERROR. EVASIVE ACTION TAKEN.
Narrative: ATX X CONTACTED CHA APCH APPROX 30 DME FROM THE CHA VOR AT 11000 FT. CHA GAVE US 7000 FT AND SHORTLY THEREAFTER, A 070 DEG HDG FOR THE VISUAL FOR RWY 20. AT THIS TIME, WE HEARD A BARON REQUEST RWY 33 AND THEN ASK IF IT WOULD BE A PROB. APCH ANSWERED IN THE NEGATIVE. APPROX 12 MI FROM THE ARPT, THE FO REQUESTED LOWER AND WE WERE GIVEN 4000 FT. AT APPROX 7 MI FROM THE ARPT, STILL ON THE 070 DEG HDG, CHA GAVE US 3500 FT AND THE FO CALLED THE ARPT IN SIGHT. APCH CTL CLRED US FOR THE VISUAL APCH FOR RWY 20 AND SHORTLY AFTERWARDS, HANDED US OFF TO TWR. WHEN WE SWITCHED TO TWR FREQ, WE OVERHEARD TWR TELL THE BARON TO TURN HIS BASE LEG NOW. THE FO CHKED WITH TWR FOR THE VISUAL RWY 20 AND WE WERE TOLD WE WERE #2 BEHIND A BARON ON THE APCH FOR RWY 33, A XING RWY. THE FO REPLIED THAT WE WOULD SLOW IT DOWN AS BEST WE COULD. AT APPROX 500 FT AGL, TWR SAID, 'THIS ISN'T WORKING OUT,' AND INSTRUCTED US TO 'START A CLBING R TURN.' WE WERE NOT TOLD TO GAR. TWR THEN SEEMED TO FORGET ABOUT US. AFTER CLBING FOR ABOUT 1600 FT IN A SLOW R TURN, CLBING THROUGH 3100 FT MSL, AND A HDG OF 250 DEGS, I REQUESTED A HDG AND ALT. WE WERE GIVEN 3500 FT AND A HDG OF 250 DEGS. WE THEN STARTED GETTING VECTORS OF ABOUT 30 DEGS HDG CHANGE FOR EACH VECTOR UNTIL WE WERE ROUGHLY PARALLELING RWY 2-20 ON AN APPROX HDG OF 330 DEGS. SHORTLY AFTER GETTING THE VECTOR OF 330 DEGS, WE WERE GIVEN TFC Y AT 1 O'CLOCK AND LESS THAN A MI. I SPOTTED A CESSNA 210 AT 1 O'CLOCK AT APPROX 1/4 TO 1/2 MI AND 300 FT. I PITCHED UP AND THE CESSNA PASSED DIRECTLY BELOW US. I POINTED OUT THE CESSNA TO THE FO AND HE RPTED IT IN SIGHT. WE WERE TOLD TO MAINTAIN VISUAL SEPARATION AND GIVEN 2500 FT. WE THEN FOLLOWED A SABRE JET FOR THE VISUAL RWY 20, NORMAL APCH AND LNDG. THE SAAB SF-340B I FLY IS A 30 PAX, PART 135 ACFT WITH NO TCASII.
