Hi to all !
I have this 3 pole filter in my receiver’s last stage. I want to put a led, so when the current is passing through my circuit the led will light on. I need this because my transmitter a lot of time, don’t work fine, so i don’t know if there any signal going to my receiver.
It is a way to check it.
Any ideas for cheap consuption ?http://i1284.photobucket.com/albums/a578/fovos1/Circuit_zpsb91f9e29.png
