    Hard to believe October is here, and it’s time to mark ours calendar for the monthly QCWA meeting on Saturday, Oct 15th starting at 11:30.  The meeting will be via Zoom.  

    Our guest this month is Richard Dillman of the Martine Radio Historical Society, and he’ll talk about their mission, and organization dedicated to repairing, restoring and operating the historical “shore to ship” radio station KPH, located on the Point Reyes National Seashore as a way to honor the men and women who for 100 years made the profession of radiotelegrapher one of honor and skill.

    For years I’ve tried to define Field Day, not in an absolute, definitive or comprehensive way but rather, in a personal one. What does it mean to me? I have narrowed it down to two key added values, again, for me.

    First of all it is the camaraderie. I spend Field Day in a group setting. I do not operate alone. Secondly, more than the ‘contest’ aspect, even though it is technically not considered one, I find that Field Day is an exercise in ‘aggregation.’ Individuals, with different radios, different feedlines, antennas and power supplies, show up on the Friday or Saturday and are expected to magically make it all work together. Except for the most avid contesting clubs, there is little to no real preparation. Sure, so and so will bring the CW station, and so and so will bring the SSB station, but is there really any real pre-matching? Not really, and yet, it works.

    I’m sitting here at this year’s Field Day, with a group that has been together for 51 years, and yet, it’s as disparate as I describe above. Multiples of each needed item show up, and maybe because they’ve done it for years, everything somehow connects and they get on the air.

    If you think about it, this aggregation characteristic provides a foundation for many aspects of amateur radio. Of course, emergency responses are made possible by this quasi-instantaneous aggregation. So too do the more mundane public service interventions. Every year I participate in the Marine Corps Marathon. Over the past few years I’ve been attached to Net Control. Here again, ‘stuff’ shows up, and like magic, we have a net control station able to transmit to and coordinate with over one hundred portable and mobile operators.

    That’s it for now, I guess I should get ready for my own Field Day. And yes, I better remember what I ‘brought’ so that I take home what’s mine and not what’s everyone else’s.

    Join the Club’s Regular General Meeting starting at 7:00 pm, via Zoom Meeting.  The Zoom link is:    https://us02web.zoom.us/j/83906871573?pwd=V3l1UkZmSGZObGI5YkhLbGFYRzRUZz09   

     Forum – “Amateur Radio RF Exposure” Join the ARRL Learning Network pre-recorded presentation on Amateur Radio RF Exposure, by Dan Brown, W1DAN. Dan is the Eastern Massachusetts ARRL Section Technical Coordinator, and President of the Wellesley Amateur Radio Society.  In May, the FCC issued a new Rule and Order eliminating the decades-long “categorical exclusion” for mandated RF exposure calculations for most Amateur Radio stations.  Effective May, 2021 Amateurs must conduct detailed calculations of RF exposure for both controlled and uncontrolled environments, and have the calculations on file in the shack. After Dan’s presentation, there will be a short discussion.  Time: 7:00-7:30 pm

    Main Program -- “Mitigating Residential Heating, Ventilation and Air Conditioning (HVAC) RFI (Radio Frequency Interference)”  The mandated use of high-efficiency DC motors in HVAC systems poses new challenges for RFI mitigation in the Amateur Radio bands.  In this presentation, VWS member Roger, KM4LHZ along with Steven, W9SAN of the Fort Wayne (IN) Radio Club will explain the physical basis for these phenomena, present brief case studies in RFI mitigation, and discuss some common myths regarding HVAC RFI. Considerations for purchasing a new HVAC system will be given.  Roger experienced this issue first-hand when he recently updated his home HVAC system, and Steve is an electrical engineer at the Regal Beloit Corporation, specializing in RFI issues.  Time: 7:30 – 9:00  pm
