    What I really need is someone to check what the voltage going to the OFDM board is. I had a failure of the internal circuit that powers the OFDM and VPS boards and added my own 5v regulator. I got mine working again but currently I have it set at 5.2v based on reading that the voltages were 5v. I found another post that said they got 6v at one of the boards. I really need to know the normal voltage is on a healthy P3A or P3P. My main worry is that and I am coming back in under high thrust at 25% battery and the battery voltage is say 14v instead of the fully charged 16.9v. Will my new buck converter drop the OFDM voltage down to 4.X volts and I lose communication, etc. It works now but I need more testing to be sure I don't have a failure in flight. Someone telling me what to set the voltage at would be very helpful. I don't want to go up to 6v blindly and over power the board or shorten it's life.
