Sam on Twitter: "Built a wider and more precise L-Band QFH this afternoon. Hopefully it's tuned closer to 1.54 GHz than the last attempt. https://t.co/dtH8wdV0JL" / Twitter
Sam on Twitter: "@luciangasparini @cql1983 @BH1WZB These measurements are similar to the most recent QFH I've built (https://t.co/tRbM4Ksbtu). It's worth experimenting with different loop sizes! I've also updated the @oshpark project page
