$10 bought me a 1978 Sears 20" TV with the Ultrasonic remote control (remote was THERE!!!) i tested it in-store before i bought it, and the darned thing works! even the remote!
I haven't mastered it yet though; the remote has only two buttons. the first is 'OFF-ON-VOL' and the second is "CHANNEL"
The first one is finicky. it turns the set on (with a loud *CLUNK*) and ups the volume, until let go. (i think?) the second press lowers the volume and if held down it turns the set off. i haven't mastered if that's the way or if there's a way to turn the volume down then back up without turning the set off/on, since there's no mute, i wonder if that's possible. either way it's neat to find a still-working set from the '70s with a working emitter remote!
Now i have to wonder if it will turn itself off or on when airplanes fly overhead? Used to have that problem all the time back when we had an old Magnavox Star System which used the same technology
