The 2 meter repeater had become very noisy several times after we have had a lot of rain. After testing for noise in the repeater shack, the technical committee decided the noise source was between the antenna and the outside of the repeater shack. Ken , KE2N, decided we should replace the generic LMR 400 coax with hardline. On December 3, 2018, an OVH team replaced the coax to both the 2 Meter and 440 antennas with 7/8 inch hardline. This hardline has a loss of only .7 db per 100 feet at 440 MHZ. Our climber was Byron AK4XR. Ken directed the operation and Gil , KMK4OZH and John KG4NXT assisted. We are hopeful that the noise will not return. In addition, the repeater receiver should be just a bit more sensitive and there will be… Read more »
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 tube manuals). Since consequences of discovery by your captors will… Read more »

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 a little as I waited for the code test to begin…. Read more »
On Sunday Sept 30, 2018, the OVH did communications support for the Prince William Half Marathon for the third time. This time the marathon had 1400 runners and also had 500 additional runners for a 5 k race. The 5 K race was a race within a race. They start after the Marathon runners had left and only did a portion of the course. The OVH was well represented by 18 members. Only one member did not show and that was because of illness. This represents almost 20% of the club. The event ran smoothly and was chaired by Wayne, N7QLK. The three net controls kept a white board of race progress. This included the current locations of 1st male runner, 1st female runner and the last runner. This helped the marathon managers run the event. Also, one runner… 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 have available, and he or she will let you know how… Read more »
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 Li and NiMH choices seldom lived up to their advertised… Read more »
