[IRCA] Fwd: [mwcircle] Steps to lower noise floor and revitalize AM radio

RadioWorld report that background noise
interference is degrading the quality of
broadcast reception, two-way communications,
mobile cellphone services and every other form
of wireless communications used today at an alarming rate.
The FCC and the ITU agree that the DC to 60 GHz+
wide-spectrum background noise floor is
increasing as more and more unregulated
electronic devices are used by more consumers in more ways every day.
While it is true that large numbers of these
devices have been in use for some time, the
question becomes: What can we do to lower the
noise floor now that the floodgates of
unregulated devices have been open for so long?
Is this an impossible task? I believe the answer is an emphatic â??no.â??
On June 15, 2016, the FCC Office of Engineering
and Technology Technical Advisory Council opened
a noise floor technical inquiry in the form of
ET Docket No. 16-191 to seek answers to the following basic questions:
1. Is there a noise problem?
2. Where does the problem exist? Spectrally? Spatially? Temporally?
3. Is there quantitative evidence of the overall
increase in the total integrated noise floor
across various segments of the radio frequency spectrum?
4. How should a noise study be performed?
The most prominent responses were from the
American Radio Relay League, the Society of
Broadcast Engineers, the NAB, the National
Public Safety Telecommunications Council, the
National Electrical Manufacturers Association,
the State of California Governorâ??s Office of
Emergency Services Public Safety Communications, Verizon and AT&T.
Unfortunately, most were anecdotal, not
accompanied with measured quantitative data.
This is largely because the responders did not
have the instrumentation resources nor the
budget to provide the quantitative evidence being sought.
Despite the scarcity of quantitative data
submissions, one clear outcome of this TAC
technical inquiry is an unmistakable consensus
among the responders: A noise floor study is not only needed but overdue.
