NVIS
Research Paper Available
(from
ARRL Bulletin)
A
thorough and fully annotated discussion of Near Vertical Incidence Skywave
(NVIS) is available in the research
paper, “Radio Communication via Near Vertical Incidence Skywave
Propagation: An Overview,” by Ben A. Witvliet, PE5B/5R8DS, and Rosa Ma
Alsina-Pagès.
First
investigated in the 1920s, NVIS propagation was rediscovered during World War
II as “an essential means to establish communications in large war zones
such as the D-Day invasion in Normandy,” the paper notes, adding that the US
Army subsequently sponsored a lot of NVIS field research, especially between
1966 and 1973. More recently, NVIS has become a popular means to enable
close-in communication on Amateur Radio HF bands between 3 and 10 MHZ. NVIS can
be used for radio communication in a large area (200-kilometer radius) without
any intermediate manmade infrastructure, and it has been found to be especially
suited for disaster relief communication, among other applications, according
to the paper.
“A
comprehensive overview of NVIS research is given, covering propagation,
antennas, diversity, modulation, and coding,” the Abstract explains.
“Both the bigger picture and the important details are given, as well as the
relation between them.” As the paper describes it, in NVIS propagation,
electromagnetic waves are sent nearly vertically toward the ionosphere, and,
with appropriate frequency selection, these waves are reflected back to Earth.
In
case the link for the research paper gets broken..
PS.. Ohio’s NVIS antenna day is scheduled for
April 22. In addition to 40 and 80 meters, we want to add 160 and 60 meters (a
good 160 antenna should also operate on 60). With the band conditions in the
trash, we need to work up alternative bands and plans to maintain communications
across the state! These new bands should make for some interesting
antenna construction projects, so get your teams busy!!

ARRL Ohio ARES
Leadership Conference
The
2017 Ohio ARES Leadership Meeting is being held on April 01, 2017 at the Marion
Technical College / OSU - Marion Campus, 1467 Mt. Vernon Avenue, Marion. Check-in
is at 8am. Folks, that’s this coming Saturday!!. This conference is open to
anyone and everyone that is interested in emergency communications and the Ohio
ARES program. We do ask that you register so that we know just how many to plan
for.. The conference room as electrical
hookups for your laptop or tablets and there’s very comfortable seating
provided as well.
You
won’t be sorry that you came and spent the day!! Here’s where to register..

NIMS / ICS
Training
The
numbers are growing for sure! Here’s the latest count we have on everyone.. Members
in the database 697. Members
completing all 4 required NIMS courses 481.
Total Number of the Courses taken by everyone in the database 4609,
Here’s the link so that you can find out if your name is on the
list..
Why
are these courses so important? The simple answer is this - without these
courses, you are not trained! Without the training, you can’t be used! Now, I’m
not going to kid you.. These courses are just the beginning of your training.
These 4 courses are the BASICS only, but they are extremely important to me and to your Emergency Coordinator.
Here’s
where you can get all of this information
http://arrl-ohio.org/SEC/training.html. This page
contains a lot of information about what is needed. Each course takes about an
hour or so to take, that’s really not much to ask now is it? You spent way more
than that to get your Amateur Radio operators license!
I
also highly recommend that you get used to looking at the Ohio Section
Website.. http://arrl-ohio.org as it changes all
the time. You’ll also want to visit the Ohio Section Emergency Coordinators
page frequently too http://arrl-ohio.org/SEC/default.html
By
the way.. When submitting copies of your certificates to us, please don’t
forget to include your call sign!!

Survey Question
Hey
Gang,
Have
you checked out the Newest Survey question on the website?. There is a brand
new question up there! You’ll find it on the left side of the main page.. http://arrlohio.org Don’t forget, once you’ve voted to go back
and take a look at how your answer stacks up with everyone elses..!!
************
Are you getting
those emails
from me? If not, all you have to do is to “Opt-In” to receive them.
Heck,
just send me an email: n8sy@n8sy.com and let me know
that you want to be added. It’s really just that easy. Please, if you know of
anyone that would be interested in this information, feel free to pass it on to
them. You don’t have to be an ARRL member or even a ham to receive these emails.
You
can always “Opt-Out” at any time if you feel this is not what you
were expecting.
Also..
are you viewing the Ohio Section Website on a regular basis? You should, it
changes all the time. Here’s a link to it.

My Final.. On this day in 1884 the first long-distance telephone call was made from Boston to New York. In 1958 CBS Labs announce
new stereophonic records. Wow.. It just took off from there..
Now
that you have some fun facts for water cooler, go and HAVE FUN!!
