Narrative:

After receiving ATIS, ground control gave me clearance to taxi to runway 16. After following an small aircraft to 16 I had no other radio contact. I could not receive ground control, approach, departure or the other aircraft. After I did my runup, I tried again. I got no answer. I did a 360 degree circle and saw no traffic. I was a little nervous but I followed the small aircraft off the runway. I took off as he was passing through 150 ft. I didn't even see any light signals.
