Hi,
Might have been a bad choice of title!
Indications are the 7T transmit bias line is faulty somewhere. 7R is
normal, 6.8-6.9 volts, but the transmit 7T line is very low, around 3.8
volts. I suspect this is the cause of no power out anywhere as the
signal switching is not working. The 7T line reads a mere 20 ohms to
ground so I suspect a failure somewhere in what hangs from that line. I
guess I will just have to work through it.
Maybe there are some known weak points someone might mention.
Martin, HS0ZED
