This has been quite a mind expanding week as I listened to John describe his favorite new digital mode, JS8. It runs on a laptop computer and manages to copy at subterranean signal to noise ratios. Wow, how does that work? And how did we get here? The journey leading to seemingly magical modes like JS8 began shortly after World War I as growing demands for commercial and government communications rapidly exceeded the capacity of manual telegraph circuits. A small group of clever inventors proposed a solution known as a “printing telegraph” or teleprinter. Its electromechanical keyboard and printer combination used a 5 bit Baudot code to represent 64 possible alphanumeric characters. Their invention was a resounding success and their company, the Teletype Corporation, went on to become a major … Read more >>

It seems our recruiting efforts have been paying off with several new members joining the club recently. When you see them at a meeting or club function, please take a minute to introduce yourself and welcome them to OVH. Club recognition has definitely helped our recruiting. So, as spring approaches with Hamfest and other activities, this would be a good time to order your club nametag if you don’t already have one.       Nametags can be ordered from the above link. It will be some time before our next custom polo order. However, I do have some generic polos (club logo but no name or callsign) available for purchase. I’m expecting a customization quote from a local vendor in time for our next meeting. This year’s Virginia QSO Party, sponsored by the Sterling … Read more >>

Happy New Year

As we enter the new year, I’m reminded  of a quote my faculty adviser kept posted on his wall: “We are surrounded by insurmountable opportunity.” Opportunities abound at OVH for programs, projects, and people. Based on your inputs, here are some ideas for programs and projects. I’ve added a couple of threads (links) to tug on for each so you can explore them further online. (1) Amateur Radio Direction Finding (ARDF) http://www.arrl.org/direction-finding http://www.homingin.com/ (2) Automatic Position Reporting System (APRS) http://www.arrl.org/aprs-mode (3) Digital Modes http://wb8nut.com/digital/ (4) Morse Code http://www.arrl.org/learning-morse-code Jeff, K9VEG, has established a weekly CW net for those interested in polishing their skills. See the OVH reflector for details. (5) 6 and 10 meter FM and Digital Anyone interested in exploring the acres of unused RF spectrum there for mobile,portable, … Read more >>

Canteen Radio

The approaching holiday season and year’s end are traditionally a time for reflection and giving thanks for our many blessings. This Veteran’s Day, lets take a moment to express thanks to our veterans – the young ones who are in harm’s way today defending our freedoms, and those who have gone before, sometimes giving all. Amateurs have a proud history of contributions during our nation’s conflicts. This Veteran’s Day I’ll cover a fascinating but little known part of that history – radios built by American and Allied prisoners of war. For a moment, imagine yourself as a WWII POW. You’re injured, on short rations, and living in primitive conditions. How will you find parts for even a basic receiver? And, of course, the design will be yours (no references or … Read more >>

Pumpkin

Cooler temperatures of fall will soon be here and, along with them, the beginning of the holiday season. I’m sure your family, like mine, has some holiday traditions which have been passed down over the years. We carry them on, not necessarily for practical reasons, but as a means of bonding and connecting with past generations.     The amateur radio family has its own set of traditions. Some, like QSO procedures, we use regularly regardless of operating mode. Others, like Morse code, seem at risk of fading away into the sunset. Many years ago, a Morse code test was part of every amateur radio license exam. General and higher license exams were administered at FCC district offices. I can still remember that crisp fall day many years ago, crammed into a room full of applicants with my 13 year old hands shaking … Read more >>

In keeping with September being national emergency preparedness month, along comes one of the largest hurricanes in recent memory. At this point, it looks like the impact on our area will be limited to a few inches of rain and some gusty winds. However, for those south of us who are in the path of Hurricane Florence, the impact will likely be devastating.      Ham radio will play an important role, both in support of local responders and in handling message traffic out of area. Info about HF traffic net times and freqs will appear on ARRL and ARES web pages. As always, two things to keep in mind when supporting any emergency. First, make sure that you and your family are safe. Second, do not self deploy. Begin by contacting your local Emergency Coordinator (EC), state what resources you … Read more >>

Mini LiFePO4’s

My 4.5 Ah mini LiFePO4 and fused cable. (The battery came with Power Pole output connector.)

If you’ve joined us in supporting Tri It Now and larger events, you’ve probably realized that the medium power setting on your HT (typically around 2 Watts)isn’t quite enough to provide reliable comms over the entire course. This is especially true if you’re using the short ducky antenna which came with it. How to improve coverage? Going with a larger antenna and/or adding a “tiger tail” counterpoise is one solution. Bill, K5AE has an excellent video on the topic at tiger tail tail video Or, you can up the power to 5 watts. This usually means buying a larger battery for your HT if you want a useful amount of talk time. If you’ve tried that option, here’s hoping you’ve had better luck than I did. Most of my my … Read more >>

MOLLE vest fully equipped

To those of you who, although new to both our hobby and the club, have already volunteered for ARES, TriItNow, and several other public service events, a hearty Welcome Aboard! By now you’re no doubt familiar with the yellow mesh ARES vests. They’re great for making you nice and visible to race participants and traffic while you’re out there with your HT. But .. where are the pockets? Where will you put your gear should you deploy in support of a real emergency? Here’s one solution. It’s a rugged vest with MOLLE loops from Canadian company Duty Apparel. Their compatible MOLLE pouches are ideal for your HT, water, and other gear from your ARES go kit (right). The rear panel needed for ARES ID (top right) is easily added either … Read more >>
