Re: LM3914 --help :/
but exactly how does it modulate the chain inputof comarators, to
disable all leds the + input of comparators should become higher than
-... am I rigth ?

... Should be easy enough using op-amp comparators with resistors setting up a 10 or 20 step voltage divider as a reference. ... For example, if the voltage swing that drives an analog meter goes from 0 volts for the needle at its full down position to 5 volts at its upper most swing, the comparators compare the voltage used to move the needle and light a corresponding LED...Terra produced just such a radio back in the 80s...I think it was called the Tri-Nav C... ...
