Hello All...
I'm working on an issue with the Tune-IP-HV LED display. It works
correctly on the tune and IP function, however it always shows full
scale on the HV function.
The analog voltages from the HV board up to the analog multiplexer (U13)
on the microprocessor board look ok. However, the multi sig voltage
going from the A/D IC (U11) on the processor board to the LM3914
display always shows +5v only on the HV function.
Could this possibly be a programming issue ?? Has anyone ever seen this
? I'm at a total loss. Hi Hi....Any help would would be appreciated !!

Steve/N7SC
