Narrative:

Flying with new first officer; very low time; 1ST trip out of training. Briefed the SID; started engines; and called for before taxi checklist. I thought he had turned on all the radios on his side of the cockpit panel and did not verify switch position. No lights to indicate radio status on/off and no markings on knob to visually verify -- the only way to check is to physically rotate the knob. The navigation radios had not been turned on; nor had communication #2. Proper radio was tuned but; after takeoff; no navigation or DME information was displaying. I was trying to fly and trying to figure out what was wrong; as the first officer didn't know what to do and wasn't helping. Not knowing what was wrong but knowing the VOR was close and required a turn; I initiated the turn left per the SID. ATC soon asked 'how are you navigating?' I responded we were flying the SID and he replied 'you're not even close; turn 30 degrees right.' very soon thereafter; I found the problem and turned all navigation and communication #2 radios on. We were approximately 1 NM east of course. No traffic conflicts arose; no further events on the SID navigation.

NOT KNOWING WHAT WAS WRONG BUT KNOWING THE VOR WAS CLOSE AND REQUIRED A TURN; I INITIATED THE TURN L PER THE SID. ATC SOON ASKED 'HOW ARE YOU NAVING?'
