CAPT FLYING DID NOT TURN TO HEADING ASSIGNED.

Narrative

WHILE BEING CLRD FOR TKOF; FLT CLRD FOR IMMEDIATE TURN TO 110 DEGS FROM RWY 22L AT ORD. AFTER TKOF TURN WAS MADE USING HDG CURSOR AND STEERING BAR ON HSI. AFTER TWR DID NOT SWITCH US TO DEP CTL; COPLT MADE CONTACT WITH THEM ON 125.0. DEP CTL ASKED OUR POS WHICH WAS THE ORD 190/10 DME HDG 190 DEGS. UPON REALIZING WE HAD STOPPED THE TURN EARLY I STARTED A FURTHER LEFT TURN WITH DEP'S CONSENT. THERE WERE NO CONFLICTS THAT I AM AWARE OF BUT THE CIRCUMSTANCES LEADING TO THIS EXCURSION ARE OF MUCH CONCERN TO THIS CAPT. COPLT HAD TOTAL ACFT TIME OF 105 HRS AND NO PREVIOUS TURBOJET TIME. WHEN CLRD FOR TKOF AND THE DEP HDG I TOLD COPLT TO SET 110 DEGS. AFTER TKOF I TURNED USING THE STEERING BAR ON HSI. WHAT I DIDN'T REALIZE WAS HE HAD SET 190 DEGS BY ACCIDENT. I FEEL I WOULD HAVE RECOGNIZED THIS ERROR EXCEPT I BECAME DISTRACTED FIRST BY THE LACK OF A PROPER HANDOFF FROM TWR AND THE COPLT QUESTIONING THIS. SECONDLY BY DEP CTL UNABLE TO LOCATE US BECAUSE THE F/O HAD FORGOTTEN TO TURN ON THE TRANSPONDER. FINALLY HE COULD NOT GIVE OUR POS TO DEP CTL (WRONG VOR TUNED IN) CAUSING ME TO MAKE THE CALL; ANALYZE THE HDG AND TRANSPONDER PROBS; CORRECT THEM AND REQUEST THE TURN TO 110 DEGS. OBSERVATIONS: CAPT AS MUCH TO FAULT FOR MISSING TRANSPONDER ON CHKLIST. I HAD VERIFIED CODE BUT NOT THE ON POS SINCE IT IS NORMALLY LEFT ON AND CTL IS THROUGH GEAR SQUAT SWITCH. ALSO; THE FLT PLAN PAPERS WERE OBSCURING MY VISION TO THE SWITCH. I DID NOT VERIFY THE HDG SELECTED AND ALLOWED THESE OTHER DISTRS TO DISRUPT MY XCHK DURING DEP PHASE OF FLT. LASTLY; THE SNOWBALLING EFFECT OF MINOR PROBS AND DISTRS IN A 2-MAN COCKPIT MAKE IT IMPERATIVE THAT THE PF DO JUST THAT--FLY THE ACFT FIRST AND HELP OR INSTRUCT SECOND!
