Narrative:

First officer flying with only one operative ADF (on first officer side). ADF tuned for SID by captain, but retuned to incorrect frequency, possibly by maintenance. After takeoff turned to 143 degrees for short period and first officer then turned left to follow ADF (tuned to oe vice epsom) had first officer turn back toward 143 degrees and while retuning ADF, ATC gave us a heading which first officer acknowledged but I did not hear. Approaching epsom and the 096 degree inbound, I had first officer turn left to intercept and acknowledged a clearance to climb to 11000'. ATC gave us hell at about 8500', had us stop climb and take up new heading. We obviously had a traffic conflict and while discussing situation with ATC several mins later, I told them that other than an intermediate altitude clearance, the only thing I acknowledged was the 11000' clearance. I did not find out about the first officer answering a heading clearance until analyzing the whole mess after landing frankfurt. Obviously, a crew coordination/communication problem, short on headwork, with a long duty period and marginal equipment (ADF) are contributing factors.

Title: WDB FAILED TO FOLLOW SID AND HAD TO BE CORRECTED BY TRACON.

Narrative: F/O FLYING WITH ONLY ONE OPERATIVE ADF (ON F/O SIDE). ADF TUNED FOR SID BY CAPT, BUT RETUNED TO INCORRECT FREQ, POSSIBLY BY MAINT. AFTER TKOF TURNED TO 143 DEGS FOR SHORT PERIOD AND F/O THEN TURNED LEFT TO FOLLOW ADF (TUNED TO OE VICE EPSOM) HAD F/O TURN BACK TOWARD 143 DEGS AND WHILE RETUNING ADF, ATC GAVE US A HDG WHICH F/O ACKNOWLEDGED BUT I DID NOT HEAR. APCHING EPSOM AND THE 096 DEG INBOUND, I HAD F/O TURN LEFT TO INTERCEPT AND ACKNOWLEDGED A CLRNC TO CLB TO 11000'. ATC GAVE US HELL AT ABOUT 8500', HAD US STOP CLB AND TAKE UP NEW HDG. WE OBVIOUSLY HAD A TFC CONFLICT AND WHILE DISCUSSING SITUATION WITH ATC SEVERAL MINS LATER, I TOLD THEM THAT OTHER THAN AN INTERMEDIATE ALT CLRNC, THE ONLY THING I ACKNOWLEDGED WAS THE 11000' CLRNC. I DID NOT FIND OUT ABOUT THE F/O ANSWERING A HDG CLRNC UNTIL ANALYZING THE WHOLE MESS AFTER LNDG FRANKFURT. OBVIOUSLY, A CREW COORD/COM PROB, SHORT ON HEADWORK, WITH A LONG DUTY PERIOD AND MARGINAL EQUIP (ADF) ARE CONTRIBUTING FACTORS.
