 US Ham Radio Operators and Government Test HF Communications

*Disaster Communications Compatibility Exercise Uses Automatic Link
Establishment*

Washington, DC, and San Francisco, CA – March 27, 2014 - US Amateur Radio
operators (ham  operators) and Federal Government radio stations are
engaged in a nationwide test of their capability to communicate with each
other by shortwave radio, in case of an emergency or disaster.

They are participating in a 12-day joint readiness exercise running from
March 27 through April 7, covering all areas of USA, using a digital High
Frequency (HF) radio system known as Automatic Link Establishment (ALE).
This High Frequency Interoperability Exercise 2014 (HFIE-2014) runs
concurrent with the federal National Exercise Program (NEP) 2014.

ALE is a standardized digital signaling protocol used by each radio
service, ham and government, to establish HF communications between their
own stations. For the first time, the government regulatory agencies (FCC
and NTIA) have authorized these stations to communicate with each other
using ALE. HF radio enables long distance communication independent of
terrestrial communications infrastructure, internet, or satellites.

To facilitate the communication testing, the Federal Emergency Management
Agency (FEMA) secured temporary authority from the National
Telecommunications and Information Administration (NTIA) and the Federal
Communications Commission (FCC). Federal Government radio stations and hams
are allowed to communicate with each other using ALE during the exercise.
Under existing rules, hams have secondary access to 5 HF radio channels on
which Government stations are the primary users.

HF radios used by Federal Government stations have the ALE capability built
into the hardware. Amateur Radio operators have implemented the same ALE
protocols using their personal computers with ham radio equipment and
software. The Special Temporary Authority allows for on-the-air testing of
interoperability between the hardware and software-generated ALE
implementations.

Participation in the interoperability exercise is open to all ALE-capable
Federal Government radio stations and to all ALE-capable US Amateur Radio
stations. While five channels are available if needed, the test plan calls
for using only two of the channels in order to minimize impact on other
stations not participating in the exercise. Specifics of the STA are as
follows:

(1) Temporary modification of the authority granted at NTIA Manual section
7.3.8(4), which authorizes Federal Government stations to communicate with
stations in the Radio Amateur Civil Emergency Service, to allow
communications with any Amateur Radio station utilizing Automatic Link
Establishment, limited to the five channels in the 5 MHz band which are
available to the Amateur Radio Service on a secondary basis, for the period
March 27 through April 7, 2014.

(2) Concurrent waiver by the FCC of that part of FCC rule 97.111(a)(4)
which limits communications with US Government stations to transmissions
necessary to providing communications in RACES, limited to the five
channels in the 5 MHz band which are available to the Amateur Radio Service
on a secondary basis, for the period March 27 through April 7, 2014.

The HFIE-2014 is a semi-annual ham radio readiness exercise coordinated by
the HFLINK organization http://hflink.com and the Global ALE High Frequency
Network http://hflink.net

It is open to all ALE-capable ham radio stations. Technical and operational
guidelines for ham and federal government stations are available at:

National Exercise Program (NEP) 2014 is a complex emergency preparedness
exercise with activities sponsored by government departments and agencies,
designed to educate and prepare the whole community for complex,
large-scale disasters and emergencies. As part of the National Preparedness
Goal (NPG), it enables a collaborative, whole community approach to
national preparedness that engages individuals, families, communities, the
private and nonprofit sectors, faith-based organizations and all levels of
government.
