I bought this wireless doorbell receiver at the thrift store for 50 cents; there was no transmitter with it. It is a Heath Model SL-6166-RX-A.
As you can see, it is powered by 117 VAC, and doesn't appear to be damaged. Does anyone here know anything about it? For example, what frequency does it operate on? Is it AM, FM, or something else? I know that the header pins are used to mate it up with a transmitter, but what is the signalling scheme?
Any insight would be appreciated. A schematic would be wonderful.
Thanks.
ETA: The two transistors nearest the tuning coil are MPSH10, and the DIP8 is an LM358N.
