  1. As we approach another Thanksgiving, I note the following SK...

    Vic Clark, W4KFC, was President of the ARRL, and honorary member of the Vienna Wireless Society. He died the morning after Thanksgiving, 1983, after having just returned home from traveling on behalf of the ARRL. At the time, Chapter 91 was known as the Northern Virginia Chapter of QCWA. After Vic's untimely death, the chapter applied for, and received, the name memorializing Vic.

    Keep Vic and his extended family in your prayers this Thanksgiving

    Mike, WA8AHZ

  2. 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
