Just finished receiver portion of build on unit ser no 3388. Everything working so far but I discovered a strange condition with the ATTN LED. Whenever the display is set for BAT voltage the ATTN LED very dimly flashes at about 10 times per second. The flashing is sort of random and only happens when BAT is selected. Seems like this control is coming from the PIC, there is no other input to the LM358...
Not a big deal, otherwise the ATTN LED works fine..
