Bzzzzt, Wrong, would you like to try again for what is behind Curtain
No.3?

In the USA, deployment of any "Active" device that transmits any
electromagnetic signal, without the appropriate License, would be
contrary to US Law. Specificly CFR47, as this is Regulated by the
Federal Communications Commission for all US Territory, Public or
Private.

Nice try though......

Actually, Title 47, Part 15, specifically allows unlicensed intentional
emissions. For example, in the AM broadcast band:



TITLE 47--TELECOMMUNICATION

CHAPTER I--FEDERAL COMMUNICATIONS COMMISSION

PART 15--RADIO FREQUENCY DEVICES--Table of Contents

Subpart C--Intentional Radiators

Sec. 15.219 Operation in the band 510-1705 kHz.

(a) The total input power to the final radio frequency stage
(exclusive of filament or heater power) shall not exceed 100 milliwatts.
(b) The total length of the transmission line, antenna and ground
lead (if used) shall not exceed 3 meters.
(c) All emissions below 510 kHz or above 1705 kHz shall be
attenuated at least 20 dB below the level of the unmodulated carrier.
Determination of compliance with the 20 dB attenuation specification may
be based on measurements at the intentional radiator's antenna output
terminal unless the intentional radiator uses a permanently attached
antenna, in which case compliance shall be deomonstrated by measuring
the radiated emissions.


This is only an example. Most of the spectrum is available for unlicensed
operation at low power, with some frequencies having higher emission limits
than others. Therefore, intentional unlicensed emissions are allowed by US
regulations. Read Part 15.
