Narrative:

Vector to join texoma one departure (TEX1.fuz) after departing dal. Belco transition is the ranger (fuz) VOR 115.7 360 degree radial. When cleared to join the 360 degree radial my first officer changed both navigation radios to 117.0 dfw VOR. I did not see him do this so we joined the dfw 360 degree radial. ATC asked why we were east of our course. The problem was found and corrected. My first officer is a very good pilot (flew military). He made a very simple mistake when looking at the chart for the texoma one departure (TEX1.fuz) for dallas love (10-3G). The dfw VOR is depicted and the frequency box is directly below ranger. There is no need for the dfw VOR to be on this departure. It is not normally used for this departure. Having it on this chart can only lead to problems like this one. Can you have it removed? It may stop it from happening again.

WHEN CLRED TO JOIN THE 360 DEG RADIAL MY FO CHANGED BOTH NAV RADIOS TO 117.0 DFW VOR. I DID NOT SEE HIM DO THIS SO WE JOINED THE DFW 360 DEG RADIAL. ATC ASKED WHY WE WERE E OF OUR COURSE. THE PROB WAS FOUND AND CORRECTED. MY FO IS A VERY GOOD PLT (FLEW MIL). HE MADE A VERY SIMPLE MISTAKE WHEN LOOKING AT THE CHART FOR THE TEXOMA ONE DEP (TEX1.FUZ) FOR DALLAS LOVE (10-3G).
