The listing, Radio Shack 430-0227 FM WIRELESS INTERCOM has ended.
There are 4 intercoms. I swiped the image from eBay :-).
One or two show yellowing from being left in the sun. As far as I know they should work fine in your house if you have just one electrical circuit feeding all your outlets.
These are intercoms you plug in your electrical system and are supposed to work through the wires I think, not over radio waves. Anyway my belief is they only partially worked for us because our electrical system is split into at least two separate circuits.
Description from Radio Shack: "The Radio Shack FM Wireless Intercom is ideal for your home, office, shop,
or anywhere else you need short-
range communication. The intercom is easy to install and operate. Simply plug the two stations into standard AC
outlets, and you are ready to send and receive calls or monitor the rooms
where the stations are installed.
The intercom includes the following features.
Precision PLL Circuit-provides clear and stable reception.
Built-In Frequency Modulation Circuit - Reduces lines noise and interference.
