Hi and thank you ... The radio was just finshed I powered up and tested buttons ect. Then I bumped the cw key to check rf power I whent back to recieve for 3 or 4 min. the screen brighted up then shutdown. Thats why I was thinking it was the power regulation. I been tracing the radio and if I got it right, I have the 3.3 volts that I think power up the cpu I have a voltage regulator and thinking of running the 3.3 volt to see if it power up however I not sure location of vdd I think the 3 volts power the cpu up and the cpu powers up the rest of the radio.?
I hope this helps? Joe?
