|Solar Cycle Peaking Now,
Next Cycle Starts in 5 Years With Less Sunspots
|Solar Cycle 24 In Its Last Big Peak Right Now
2015 - The present solar cycle is in its second and strongest
peak right now. The present levels of moderately high solar activity
with occasional solar flares are expected to continue through 2015 and
then subside dramatically over the next 4 years. Then we should see the
solar minimum for 3 years. An upswing of the next solar maximum, Cycle
25, is predicted to peak between year 2022 and 2025, but be somewhat
less potent than our present cycle. The following chart shows our
present position in the cycles.

||US Ham Operators and Government Test HF Radio Communications
|Disaster Communications Compatibility Exercise Uses Automatic Link Establishment
Washington, DC, and San Francisco, CA – 27 March 2014 - US Amateur Radio
operators (ham operators) and Federal Government radio stations
engaged in a nationwide test of their capability to communicate with
each other by shortwave radio, in case of an emergency or disaster.
They participated in a 12-day joint readiness exercise which ran from
27 March through 7 April, 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)
ran 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
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 was 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 called for using only two of the channels in order to minimize
impact on other stations not participating in the exercise. Specifics
of the STA were as follows:
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 27th through April 7th 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 27th through April
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: http://hflink.net/hfie2014
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.

The 5000+ member HFLINK forum was asked: "What type of antennas do you use for ALE?"
Operators responded to the poll with many different types of HF
the above chart shows, autotuners and broadband antennas tend to be
used most often
by ALE operators. Autotuners mounted at the antenna feedpoint (32%) are
deployed slightly more often than broadband antennas (31%) or autotuners
at the radio. The single most popular type of antenna is the T2FD
(14%). Click on the

|HF Interoperability Exercise
The Sound Of ALE
|If you tuned into your shortwave radio in October 2013, you may have heard a gobble-gobble noise. What may seem like a flock of wild turkeys were actually the sounds of the HF Interoperability Exercise,
and it was in full swing. It started Friday the 4th of October,
and ran for 10 days. Ham operators all over the world were on
the air for this international communications preparedness exercise,
using Automatic Link Establishment (ALE). The innovative ALE system is a
digital selective calling method, enabling radio users to ring each
other up on High Frequency shortwave using their callsigns like a phone
number. HFIE, as it is known among hams, happens several times per year
and is sponsored by HFLINK.COM and the Global ALE High Frequency Network (HFN) organization.
Kurt Stephens KJ4AYT, a radio operator in Florida, had this to say: "I
use ALE a lot, both in my professional career and as a ham. I'm really
excited to be participating in HFIE. Within the first hour, I was able
to easily get signals to three different continents with my Micom 2
radio. I recently designed a new antenna for my station and I'm checking
the performance of it in this exercise. I call it the WOLF antenna. It
has good broadband SWR on all the HF bands, perfect for ALE. I look
forward to making lots of new contacts with it."
Another ham, John Lawson W4JML, commented, "I'm in Wyoming and I need to
use ALE with Army MARS, so I decided to get some more experience with
it during this exercise on the ham bands. I downloaded the free PCALE software
and hooked the computer up to my Icom IC-765, running into an 80m delta
loop antenna. Amazingly, within a few minutes after setting it up to
scan, I made my first ALE contact when Kurt KJ4AYT called me on 7
megahertz, and did some texting. I'll be on this again tomorrow for
Over three thousand ALE stations have registered so far, and many of
them are on-the-air this week talking by single sideband (SSB) analog
voice or digital texting. Some use the exercise to provide training or
maintain their proficiency in HF Interoperability; an important issue
these days, due to the new digital standards for governmental and
non-governmental organizations in emergency and disaster communications.
The distinctive turkey gobble sounds of ALE can usually be found on the following frequencies.
|Over a Decade of ALE HFLINK
celebrated 13 years of ALE in 2014. The HFLINK forum has become a
gathering point for amateur radio operators and professionals in HF.
The organization was founded by Bonnie Crystal KQ6XA, as a High
Frequency Interoperability international resource for ALE and Selective
first large scale organized Ham Radio ALE nets began in late 2001,
during the recovery from the 9-11 disasters. Since then, HFLINK has
grown to over 5500 members. Through teamwork, frequency coordination,
technical standards, and protocol optimization, ALE has become a widely
accepted ham-friendly, interference-free system worldwide.
|FCC Changes 5MHz Ham Radio Rules, Adds Data Comms
In 2012, FCC adopted new rules for the 60 meter band.
How do these changes affect USA hams?
the new rules, Ham Radio operators in USA are allowed to use Data modes
on 5 channels in the 5MHz band, with some restrictions. The maximum
power level is 100 Watts PEP with reference to a dipole. One of the
channels that previously was prone to constant interference has been
replaced with a clearer frequency. For a more detailed information
about the changes, please see HFLINK 5MHz News.
||Global ALE High Frequency Network Celebrates 7 Years of Continuous 24/7/365 All Band HF Digital Service in 2014
Global ALE High Frequency Network (HFN) set a new up-time record by
operating 100% continuously on all international amateur radio
shortwave bands simultaneously 24/7/365 for 7 years.
Relying on HF (High Frequency)
ionospheric communications, all radio stations in this worldwide system
scan the ham bands every 10 seconds, rapidly maintaining contact
through short digital bursts of signals using a system known as ALE
(Automatic Link Establishment). With about 4000 registered operators,
the HFN covers a vast area of the planet.
All ham operators are welcome and invited to participate in the net on
the air at any hour of the day or night, for normal QSOs and messages,

ALE was originally an expensive system for government
services, but recent innovations in digital technology have brought the
cost way down. The first organized amateur radio ALE nets began in
2001, corresponding with the release of the free PC-ALE software
controller for ham radios. Several years of development by the
4600+ member HFLINK organization adapted ALE to be a ham-friendly,
interference-free system. In 2007, the internet- connected HFN
network went into full scale 24-hour service. HFN rapidly expanded to
cover large areas of the earth, and it has become the prime framework
for ham radio operations using the global standard ALE system. In
keeping with its roots, ham radio ALE still maintains compatibility and
interoperability with goverment ALE radios, many of which are also
available now on the surplus market and being used by hams. Nearly
every major HF SSB radio manufacturer in the world is now marketing an
