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!!
Have you gotten registered for the “Handbook Giveaway” drawing yet, you only have until the end of this week! That’s right, April 1st is this coming Saturday!
To enter the drawing all you need to do is fill in a couple of boxes on the form.. (your name and email). That’s you need to do to be entered into a drawing to win a 2016 ARRL softcover Handbook. There’s nothing else required (Oh.. You do need to be a resident of Ohio to win..)
The winner will be mailed the Handbook at my cost. This is being offered just to see how many folks are really checking in on the website. Got the idea? Best of luck to you!!
Here’s a link to the form.. http://arrl-ohio.org/handbook.html
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: email@example.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. http://arrlohio.org
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!!
