What about the receivers that worked at receiving the signals from those
transmitters????

They are built into the sick/dead garage door openers, which ended up tossed
into a dumpster.

They're usually built onto the "back cover". When I replace an opener,
I pull that cover off and set it aside -- self-contained remote control
system (albeit one in an unusual form factor).

On the chamberlain/Crafstman GDO I have sitting on the bench right
now, the RF receiver is on the same card as the motor controller. It
is one FRU for just about everything .

Yes. And you can, for example, wire an arbitrary load in place of the motor
and have a "remote controlled" whatever.

I plan to install a momentary switch in one of the empty "knockouts" in
the car dash wired to the opener's xmtr with the "receiver" connected
to a light to illuminate the driveway. So, when backing into the
garage, at night, we'll be able to *see* the driveway (instead of
relying on the feeble backup lights on the car)
