Survivable Asset Should
a Community Need to Navigate an
Electromagnetic Pulse Attack |

The overflight of
the Chinese surveillance balloon has emergency managers
considering how they will speak to the public should an
electromagnetic pulse (EMP) cripple power, telecommunications
or internet infrastructure. Once a possibility
discussed mainly within the tin foil hat crowd, the recent
demonstration of the ease with which a
high-altitude device can enter our airspace has
brought the topic to the forefront for safety officials.
Research generally has painted a dim picture of the
survivability of unprotected electronics after a pulse
event. But the scenario would vary widely.
Factors that favor component survival include . . .-
Electronic systems that are disconnected from the power grid.
-
Small electronic components with short conductor
lengths.
-
Shielded electronics – unintentionally or
intentionally.
The issue has increased questions about how to protect
public emergency communication devices such as
the
RadioSTAT System, which, it has been suggested, could be a
valuable asset in the aftermath of such a disaster. |

Portable Electronics Case |
Because the system can be kept off-line and protected in
a simple EMP protection bag and because most radio
receivers today are in cars, which may have a certain
amount of natural immunity due to shielding and other
factors, the question of protectability has been posed. As a
response, manufacturer
Information Station Specialists
now offers EMP protection solutions for the RadioSTAT
System, available for new systems and for after-market
upgrades. |

CHARLOTTE, NC: The
2022 Queen's Cup Steeplechase Race was a thundering
success for the horses and jockeys and almost all of the
patrons. But an unexpected cellular network overload
made it obvious to organizers and safety officials that
when that element stumbles out of the gate, it can take
a lot down with it.
“The outage caused an emergency issue for medical and
fire apparatus just with getting people onto the race
grounds,” Chairman Bill Price told The Source.
“The 2022 event became a traffic nightmare.”
Incoming patrons count on their GPS systems for directions and
can become disoriented if that service would be
disrupted. So this year, event organizers will operate
an
EventCAST Radio System on 1620 AM in parallel with
their other communication systems to make sure everyone
is on the same page, no matter what.
Price stated, “With a 3-mile radius, the EventCAST
station will be a great way to communicate a variety of
things to patrons that will make their trip in and their
access to the gate easier.” |

Virtually everyone
has a car radio right in front of them, which allows
attendees across a spectrum of technical abilities to
receive parking, traffic and event background
information in advance of their arrival.
Hear an
example recorded at Orlando's Hamcation Amateur Radio
Convention.
The EventCAST System can also be employed to transmit live public address audio
during an event. The Queen's
Cup will broadcast the call of the races and will have
the capability to make instant announcements if needed.
The nearby Town of Mineral Springs, North Carolina, will
hold the FCC license for the radio service.
Last year, 313 Entertainment, which manages Pine Knob
and two other amphitheaters in the greater Detroit area,
provided three separate EventCAST Systems for concert
attendees on 1640 AM in cooperation Oakland County
Emergency Management. 2022 was the 50th anniversary of
the Pine Knob Music Theater, where the radio service was used to
set the theme for their summer of celebration.
If an emergency (traffic, cellular, safety, severe
weather, etc.) were to occur at an event, EventCAST
Systems provide an efficient way to apprise patrons, who
can be instructed what to do, and especially how to make
an orderly exit. Emergency messages can be kept on hand
for instant insertion and broadcast by security
personnel. |

There's a lot to
know if you're arriving at a gravel pit or a cement
plant with your truck, and it’s your very first time.
One leading supplier of aggregates and heavy building
materials in the US is broadcasting safety regulations
to arriving truck drivers so they are more prepared when
they enter their gates. The company is utilizing the
InfOspot AM Radio Transmitter System to generate the
broadcasts at US locations that number in the
hundreds. |
|
The
InfOspot AM Radio Transmitter System
with Range Extender Outdoor Antenna and Tuner |
“The InfOspot AM Radio transmitter
is a robust design, is easy for us to set up, and allows
us to broadcast messages with impressive clarity, ”states
the company’s
Environmental Health and Safety Manager. “These
transmitters at each of our sites will help ensure
customer, contractor, and employee safety for years to
come.”
The company has
commissioned a custom radio system,
designed specifically for them by Information Station
Specialists. It includes convenient USB / flash drive
audio repetition so messages can be kept current as
regulations change. All equipment is housed in a 19”
wall-mounted rack frame for operation and service
convenience.
The InfOspot system
requires no license under FCC Part 15 Regulations and
can deliver a quality signal across a 1200-2500' range
(1/4 to 1/2 mile).
Broadcasts will be
recorded by bilingual announcers to get safety
information in front of as many drivers as possible. See
Recording Services. [Generally you never want to
be in front of one of these drivers, but this would be
an exception.]

Information Radio Stations is a generic term
synonymous with Travelers Information Stations (TIS), Highway
Advisory Radio Stations (HAR) / Highway Information Systems &
Low Power Radio Stations (LPR). Operation of the stations is
governed by FCC Part 90.242 Rules. A FCC license is required.
Information Radio Stations may be fixed or portable.
Subcomponents may include transmitter, antenna and ground
system, digital voice player, wattmeter, cabinet with
conventional or Corbin locks, lightning arrestors for RF, power
and telephone lines, coaxial cable. Most stations employ black
maximized antennas to discourage ice accumulation and security
measures to prevent unauthorized program access. Options include
synchronization, battery backup, solar power, remote programming
by local, network or telco, multi-station audio distribution via
RF or LAN / WAN or wireless network. |
