Narrative:

Flight cleared to 13000 ft and cleared to intercept the cvg 020 degree radial. Captain had mistakenly set falmouth 117.0 in navigation radio instead of cvg 117.3. Copilot advised departure control that the radial (cvg 020 degree) appeared to be left and requested a left turn to intercept. Departure ok'd this. After a turn was started, departure asked if we were intercepting radial and advised to turn to 250 degrees. Turn was initiated and departure advised us to level at 10000 ft. Aircraft climbed to 10500 then back down to 10000 ft. The crew discovered the frequency error and intercepted radial. Departure then asked if we were climbing to 13000 ft. We stated that we were level at 10000 and would climb to 13000 ft. The problem was caused by a mis- dialed navigation radio frequency, however, this was compounded by the controller's failure to question our request to turn left to intercept the cvg 020 degree radial. In fact, at this time we were already on the radial. This left turn, which he cleared us for, could have caused a traffic conflict, as he next requested that we level at 10000 ft. Supplemental information from acn 205028: captain was flying the aircraft and I was working the radios. I had my VOR set for the second fix flm 117.0. The captain mistakenly set his VOR to 117.0 instead of cvg 117.3.

Title: HDG TRACK DEV CREATES AN AMENDED CLRNC WHICH INDUCES AN ALTDEV ALT OVERSHOT ON DEP PROC.

Narrative: FLT CLRED TO 13000 FT AND CLRED TO INTERCEPT THE CVG 020 DEG RADIAL. CAPT HAD MISTAKENLY SET FALMOUTH 117.0 IN NAV RADIO INSTEAD OF CVG 117.3. COPLT ADVISED DEP CTL THAT THE RADIAL (CVG 020 DEG) APPEARED TO BE L AND REQUESTED A L TURN TO INTERCEPT. DEP OK'D THIS. AFTER A TURN WAS STARTED, DEP ASKED IF WE WERE INTERCEPTING RADIAL AND ADVISED TO TURN TO 250 DEGS. TURN WAS INITIATED AND DEP ADVISED US TO LEVEL AT 10000 FT. ACFT CLBED TO 10500 THEN BACK DOWN TO 10000 FT. THE CREW DISCOVERED THE FREQ ERROR AND INTERCEPTED RADIAL. DEP THEN ASKED IF WE WERE CLBING TO 13000 FT. WE STATED THAT WE WERE LEVEL AT 10000 AND WOULD CLB TO 13000 FT. THE PROBLEM WAS CAUSED BY A MIS- DIALED NAV RADIO FREQ, HOWEVER, THIS WAS COMPOUNDED BY THE CTLR'S FAILURE TO QUESTION OUR REQUEST TO TURN L TO INTERCEPT THE CVG 020 DEG RADIAL. IN FACT, AT THIS TIME WE WERE ALREADY ON THE RADIAL. THIS L TURN, WHICH HE CLRED US FOR, COULD HAVE CAUSED A TFC CONFLICT, AS HE NEXT REQUESTED THAT WE LEVEL AT 10000 FT. SUPPLEMENTAL INFO FROM ACN 205028: CAPT WAS FLYING THE ACFT AND I WAS WORKING THE RADIOS. I HAD MY VOR SET FOR THE SECOND FIX FLM 117.0. THE CAPT MISTAKENLY SET HIS VOR TO 117.0 INSTEAD OF CVG 117.3.
