This is the 3-Station/3-Channel FM Wireless Intercom, previously known as the Radioshack FM Wireless Intercom, 2-channel, and now known as Advanced 3-Station/3-Channel FM Wireless Intercom - what makes it "advanced" is not clear.
RadioShack Model: 43-3105 | Catalog #: 43-3105
The unit replaces the model 43-219 and remains 100% compatible. There have been similar models prior to 43-219 that are older and also compatible.
It is a type of FM Wireless Power Line Intercom that places RF modulation on the AC electrical system of the building.
