Narrative:

En route to osh on warbird arrival had to stop short at fld due to severe WX. ATIS at osh suggested alternate airports. Arrived at fld at XA30 local. Had to wait until after XF00 local for airshow to finish at osh to resume. When I arrived at the airplane 2 sky-raiders were taxiing out led by a gentleman in an orange hat and an orange vest (looked like previous FAA ground crews at osh). I told him I would be firing up the T34 to go to osh. He said follow the sky-raiders. It took me a little longer to fire up and get going. He walked me out to the taxiway much like the crews at osh where you monitor the control frequency and keep quiet. While I was taxiing down beside runway 18/36 (runway the sky-raiders just departed), I thought I should announce (it was very light activity at fld, no other aircraft on the txwys or runway). I transmitted on 120.4, the control frequency when I arrived and they told me to transmit on another frequency. When I transmitted on this frequency the controller told me I just taxied through the approach end of an active runway 27. I was told to continue to taxi to runway 18 for departure. I taxied and took off for the warbird arrival to osh. Should have studied the fld NOTAM closer.
