At the voltage regulator (Q2 on the \ndiagram, Part # ua7806c) readings should be approx 16 v on the input pin, 6v \non the output pin, with the center pin ground. My readings were 16 v in, 3.2 \nv out, center pin ground, isolating the problem to the voltage regulator.\nI hope this info can be of use to others.\nBill KB2RC\nAmsat 6986 \n\n\n", "attachments": [] }
