On Tuesday 16th May, Newport Amateur Radio Society welcomed Fred Cirera, W6BSD all the way by Zoom from sunny California, who delivered an excellent presentation on ‘Building filters for amateur radio’.
We ‘met’ Fred during the lockdowns of the recent Covid19 pandemic, when he somehow stumbled across our then regular Thursday evening zoom sessions running in place of face-to-face club meetings and Fred has been a regular attendee on our continued Zoom sessions since then, and we are all very fortunate to have met him.
From low-pass filters to smith charts, and from frequency response plots to component calculation websites – Fred covered it all! If you want to find out how to go about building a filter for your amateur radio project, determining which type of filter is needed, how to determine the values of all of the components required to build your project – feel free to take a look at Freds’ first class presentation which can be found by clicking on the image below.
It was a fantastic talk. Very interesting software tools used so that we don’t need endless pages of calculations, which in my book is a win win 🙂
