| | Intro I was interested in it for quite some time and now got myself a Home and amateur (ham) radio license. This allows me to build radios, antennas and other equipment as well as to use it on the air. The first radio I build was a kit, a QDX - Digital Transceiver. This transceiver allowed me to work multiple bands, 80m, 40m, 30m and 20m.
