Hello,
im at my wits end. Im doing a project for University, i have to do an entire manufacture run in 10 weeks... so its not 3 weeks from deadline and the PCB is made but the tone decoder is doing something odd!!

I hope the image works, if not i will find one and post values.
the problem is that the signal is LOW when NOT recierving. this is a massive problem as when the sensor has no signal it it floats high...
Anyone got any ideas? anything i can try even if its an insane suggestion?
thanks!
