It’s been over a week since I got back from attending Anime Weekend Atlanta for the 16th year in a row, and if I had to be honest with myself, this really was the best one ever. It had nothing to do with the convention’s content but rather had to do with getting to hang ... Read More

Current State

Hi there! This is a landmark first post in almost four years here on w4jdh.net! Today we’re diving into the realm of amateur (ham) radio and Linux, specifically how to set Arch Linux up as both an APRS I-Gate and a dual-band D-STAR hotspot using the G4KLX software compiled from source. Assuming you don’t have ... Read More
