Narrative:
Just joining the fossl 4 arrival into phx, first officer tuned in wrong outbound radial from gallup while I had left the flight deck to use the restroom. Tuned 242 degree radial instead of 222 degree radial from gallup to intercept the 242 degree radial off on zuni VOR. I believe the mistake was mostly a result of pilot fatigue and compounded by no xchk, as I was still away from my seat. This was the third week of the same 4 day trip. Short overnights followed by early reports have consistently produced fatigue on this trip. The short layovers have been a result of WX, mechanics and scheduling problems. This was one of many small errors made during the last 3 weeks of this schedule. The other errors were caught during the xchk by the other pilot before any deviation or situation occurred. One or both pilots would catch the mistake during normal xchking. This error wasn't noticed until I returned to the flight deck and asked about our position. ZAB asked about our filed routing and turned us left 50 degrees for traffic. Pilot xchk is critical in fatigue sits!

Title: PF SET RADIOS INCORRECTLY FOR ARR WHILE PNF WAS OUT OF THE COCKPIT. TRACK ERROR DISCOVERED BY CTLR AND PNF UPON HIS RETURN TO COCKPIT.
Narrative: JUST JOINING THE FOSSL 4 ARR INTO PHX, FO TUNED IN WRONG OUTBOUND RADIAL FROM GALLUP WHILE I HAD LEFT THE FLT DECK TO USE THE RESTROOM. TUNED 242 DEG RADIAL INSTEAD OF 222 DEG RADIAL FROM GALLUP TO INTERCEPT THE 242 DEG RADIAL OFF ON ZUNI VOR. I BELIEVE THE MISTAKE WAS MOSTLY A RESULT OF PLT FATIGUE AND COMPOUNDED BY NO XCHK, AS I WAS STILL AWAY FROM MY SEAT. THIS WAS THE THIRD WK OF THE SAME 4 DAY TRIP. SHORT OVERNIGHTS FOLLOWED BY EARLY RPTS HAVE CONSISTENTLY PRODUCED FATIGUE ON THIS TRIP. THE SHORT LAYOVERS HAVE BEEN A RESULT OF WX, MECHS AND SCHEDULING PROBS. THIS WAS ONE OF MANY SMALL ERRORS MADE DURING THE LAST 3 WKS OF THIS SCHEDULE. THE OTHER ERRORS WERE CAUGHT DURING THE XCHK BY THE OTHER PLT BEFORE ANY DEV OR SIT OCCURRED. ONE OR BOTH PLTS WOULD CATCH THE MISTAKE DURING NORMAL XCHKING. THIS ERROR WASN'T NOTICED UNTIL I RETURNED TO THE FLT DECK AND ASKED ABOUT OUR POS. ZAB ASKED ABOUT OUR FILED ROUTING AND TURNED US L 50 DEGS FOR TFC. PLT XCHK IS CRITICAL IN FATIGUE SITS!
