OHR DD-1 digital display
Elsewhere on my Youtube channel, • OHR DD-1 digital dial video for Marshall , I posted a short video regarding my DD-1 kit.
The issue of the bad upper three LEDs in the display was resolved when I tracked down a solder bridge across some common resistor terminals that effectively shorted two pins on the main counter/display driver.
That's all sorted now, so we here is short video of the finished build displaying a 10MHz frequency standard.
