Mike is it, well you are one up on me cause I have never been to Arizona

Thanks for the reply I might give your NPN level shifter example a try. I do not require bi directional seeing as it is a PWM signal for motor speed control via an Electronic Speed Controller. Only being a rank amateur electronics hack, with the emphasis on amateur and hack, I think that I have a 2n3904 laying around so I am halfway there. I will let you know how I go and great diagrams you have done there for me. Much appreciated.
