I recently picked up an 11/73 [M8190 / KDJ11-B in a
BA23] and when I
finally got around to powering it up today it was failing test 61 Line
Clock during power up.
I found some info on the H7864 power supply in a uVax doc which says
that the BEVENT L signal from the power supply is enabled by the LTC
swtich on the control panel PC board.
I couldn't find any docs with details on the 11/73 control panel PC
board. I can see a three header pin jumper, which has two of the pins
jumpered together, and a dual rocker switch. Does anyone have docs
for what these jumpers / switches do?
Through trial and error I found that flipping the first rocker switch
made the test 61 Line Clock failure go away, but for future reference
I'd still like to know exactly what the switches and jumper are
supposed to do.
Switch 1 enables the LTC to function under software control, switching
it off disables the LTC function. Switch 2 isn't used.
Mine has a 4-way connector which are the 12V and 5V test points - 12V
nearest the switch.
