In circuit, 7805 regulator puts out?2.0?volts.? Of course, transceiver not working.
When I check output of regulator with output pin not connected to circuit, it puts out 5 volts.
With power off, continuity checks to all components served with 5 volts seems OK.? No opens nor? shorts to ground that I can find and no solder bridges. C37 tested out of circuit at 9.5 microfarads
Power in to regulator is 12 volts.
I have previously built working QCX mini, QCX and QCX+ in several frequencies.
This mini is a Rev1 PCB with T1.07a software.
Any help will be much appreciated.
Incidentally, I recall someone saying they have printed out the traces for the 5 volt circuits.? They would be helpful to me if still available.
Thanks and 73
