I had some time tonite\nto work on it and here's what I got. On both a1 a3, and e1 e3 pairs I'm\nreading only 1.0 volts. Between a2 a3 , and e2 e3 pairs I see only .5 volts\nat half range, IE an elevation of 90 degrees = a reading of .5 volts. I'm\ngoing to order a new Q2 UA7806C and this should do it. Only question I have\nis why Q2 failed to only output 1 volt, don't they usually fail and output 0\nvolts? I'm thinking it might be something else in the circuit feeding power\nto Q2. If so I will work this further when I actually take the rotor box\napart with the new Q2 in hand. One other thing, I wish I can find all my\ncomponents' I boxed up when I moved. I bet I have 10 of these in stock :)\nThanks again for all the help guys, the electronic copy of the manual was a\nbig help as I can't find my copy....\n\n \n\n73 Jeff kb2m \n\n \n\n \n\n> I'm having a problem with my 5500 after a thunderstorm.
