The US Air Force Marathon is scheduled for Saturday,  18 Sept. 2021.

Volunteer registration opened on 1 May 2021

Per 2021 Volunteer Lead for Ham Radio Bob, N8ADO:

Most of what we will do this year is mostly the same as in previous years, but there are a few changes planned that I will share with you as we get closer to the event. We will need a lot of volunteers to do this well and I encourage you to pass along this information to your ham friends and I ask that you encourage them to join us.
When you register, select “Race Day” as the category to which you want to volunteer. You will be presented with a list of jobs. You want to select “Amateur Radio Operator”.
The rest of the form should be fairly self-explanatory, but I note that the boxes where you fill in your info are often hard to see.
The form includes a number of places for optional info, for example, what position did you fill before. I have all this info, so do not worry about those details. If you wish to repeat a previous assignment or if you wish to try something different, the best way to communicate that desire is to email Generally, you will be considered first for a position which you have held before. For other requests, they will be considered in the order they are received.
The website to register is
Select the box:  “Volunteer Here”
You will be presented with a couple options, but I hope that you select the box “Go to Volunteer…”
If you have any issues with the process, drop me a note.
I know that many of you are not happy with having to go to your assigned spot before dawn and sit for a few hours waiting for the runners to arrive. This is a consequence of safety and security issues with having the event on an Air Force Base and there is little that we do to fix this. But there are a few assignments that are not on the base that might be more suitable. Also, if you cannot participate in race day events, consider volunteering to help with some of the preparation. For example, I could use a team to check out prospects for the repeaters that we will use to conduct communications during the event.

From the ARRL Website:


On April 20, the FCC’s Enforcement Bureau issued a new Enforcement Advisory, repeating the admonishments contained in a January Advisory that no licensee or user of the Amateur or Personal Radio Services may use any radio equipment in connection with unlawful activities of any nature.

The Commission specifically cautioned that individuals found to have used radios in connection with any illegal activity are “subject to severe penalties, including significant fines, seizure of the offending equipment, and in some cases, criminal prosecution.”

In addition, licensees should be aware that illegal operation in any service or band, including completely outside the amateur allocations, could potentially disqualify a person from holding any FCC license in any service, not just the Amateur Service.

Any amateur observing a suspicious infraction that might be of illegal or criminal nature should report it to their local law enforcement office or the FBI.

The ARRL released ARLB011 reminding amateurs that updated Radio Frequency Exposure rules become effective on 3 May 2021.

These are the same rules that have been in effect since 1997. The primary change is that amateur radio stations are no longer categorically exempt from performing an evaluation. The RF Exposure limits have not changed.

More details on the ARRL RF Exposure website.  Resources available on that page are links to an ARRL FAQ their RF Exposure and You document, an extract from the chapter on conducting a station evaluationforms you can use, and an online RF Exposure Calculator

Here’s another RF Exposure calculator by VP9KF that displays the info in a different way including discussion of duty cycle of different modes.

You do not have to submit any information with the FCC.  Simply complete the documentation and file it with your license documents. 

The ARRL states that they will be updating their site with any applicable changes as they are identified.

N8QHV’s latest training was on the Medical Reserve Corps

Per the GOBA Website:


This will be another difficult year for major bicycling tours, and we are sad to announce that GOBA 2021 has been canceled because of the pandemic. The chances of safely holding a weeklong ride for 1,200 to 1,500 cyclists in 3 1/2 months from now have become increasingly slim, and health department restrictions on mass gatherings and temporary camping are unlikely to allow it. GOBA just wouldn’t be the big, fun biking festival that tens of thousands of cyclists have come to love and expect since 1989.

But Outdoor Pursuits recognizes that many cyclists are eager to ride on a tour this summer if they can do so safely. Therefore we have been working with health officials and the GOBA 2021 communities to create a smaller, simpler alternative event that would pass muster even under current COVID-19 rules.

The result is the new, one-time Western Ohio Bicycle Adventure (WOBA), which will have a limit of 500 participants and be held on the same days (June 19-26) and in the same towns (Sidney, Wapakoneta, Versailles and Troy) as GOBA would have been.

The tour will use a hub-and-spoke route format, with cyclists riding 50-mile loops on seven days, and the option for 100 miles on one of the days. Participants will have their vehicles throughout the event and drive from overnight town to overnight town instead of bike.

The camps will have showers, toilets, tent and towel service, RV parking, a bike mechanic and limited food sales, but they will lack some of the other amenities of a GOBA camp. The vehicles will make it easy for participants to access lodging, food, entertainment, services and shopping in the communities. Increased sanitizing, facial-covering and social distancing will be practiced in the camps, food stops and other WOBA venues.
