Transmitters intercepted by the poster belong to a group of devices knownas “Part 15 devices.”
Part 15 devices consist of two general classes: “IncidentalRadiators” and “Intentional Radiators.” Incidental radiators include a vast number ofhousehold electronic devices such as computers, radio and television receivers,videotape recorders, telephone answering machines, light dimmers, and high-efficiency fluorescent light bulbs, etc. Intentional radiators in the home includecordless telephone handsets and base units, garage door opener controllers,wireless security system components, radio-frequency remote controls for homeentertainment equipment, and baby monitoring systems.
As for receiving the signal, the act is very straightforward:

Sec. 2511. Interception and disclosure of wire, oral, or
electronic communications prohibited
2a[ii] (d) It shall not be unlawful under this chapter for a person
not acting under color of law to intercept a wire, oral, or
electronic communication where such person is a party to the
communication or where one of the parties to the communication
has given prior consent to such interception unless such
communication is intercepted for the purpose of committing any
criminal or tortious act in violation of the Constitution or laws
of the United States or of any State.
And while you may feel that this section of the Act precludes civil and criminal penalty, your task is then to explain how prior consent can be given without knowledge of the interception? Not to mention the right and expectation of privacy.
