Re: Optocouplers @ Audio Freqs ?
BTW,an audio isolation tfmr was the very first thing I tried,both on input and output of the GLI and without the RS GLI. As far as turning up the volume,the thing with that is the high freqs are attenuated noticably.<p>I didn't think about a preamp though.<p>As to the "all this discussion"...

Re: RF remote signaling
The walkie talkie is a good idea and RS has one that has a orange button on the side that will transmit a tone when pressed, eliminating some tone generating circuit.Simply short the contacts then hook up as Dean said.<p>I think Ramsey still sells the 567 tone kits that would make this project very ...
