Top Amateur Radio Websites – Issue 2619

This week, we’ve pulled together a few items that touch on both the experimental and the practical sides of our hobby. There’s a look at an interesting open-source SDR project, the LinHT An Experimental Linux-Based Software-Defined Handheld Radio, which pushes the boundaries of what a handheld can do, especially for those keen on digital voice and custom platforms. We also found a clever QRP tuner design, the Pi-Tee QRP antenna tuner, that offers a lot of versatility in a small package, something always useful for portable operations or even a compact home station. For those working the higher bands, a detailed guide on building a 70 cm repeater antenna is included, which could be a good weekend project. And for anyone still finding their footing with digital voice modes, EvoHam – Simplifying Digital Voice for Every Ham provides a solid resource. Finally, a handy ADIF log analyzer, Amateur Radio Logbook Adif File Analyzer, is worth a look for anyone wanting to visualize their operating patterns.
