Narrative:

Miscom. I requested orange departure (330 degree heading) after departure and I heard the indication taxi turn hotel at the end of 19R but next indication was position and hold. I understood that after departure turn right at hotel (this meaning was a quick right turn over hotel) immediately and I departed and turned at hotel and assumed the tower was allowing me to avoid wake turbulence from a jet arrival. After the departure switched to john wayne advisories and received no indication of a problem on departure and continued en route to corona then returned with still no indication of any problem earlier. I received the troubling news from an instructor where I fly out of and did not realize that there was a problem with my departure. Corrective actions -- need to confirm communication with instructions received from the tower or the controling agency I am communicating with. I realize that I cannot interpret what my instructions are, but I need to completely understand them and confirm them at all times. I further plan to spend time with an instructor to improve on my communication skills for future flying.
