Haven't noticed my dogs doing anything when I activate the remote but I'll sneak up on one of them and put it by her ear and see if it wakes her up!
This is an electronic ultrasonic, has a teeny mylar speaker of some kind that transmits the sound. I may grab a few other remotes to goof around with on this project if the new transistor doesn't do the trick.
On the reverse motor circuit, I wasn't sure how that works either but it may just be something that changes the intensity of the signal and that's how it knows to reverse or not.
I was told the 165V I was reading as in the 60's is probably just due to the high resistance + the meter loading it down. This was figuring in the resistance of 2 meg in the circuit and appx 1 meg of my electronic meter. Does this sound right?
