My name is Geoffrey, I am a French citizen and passionate licensed Amateur Radio operator. I hold a French license under the call sign F4FXL since 2008. Just out of fun I passed General US license in 2015 and upgraded it to extra in 2018. My US call sign is KC3FRA. This site deals primarily with ham radio, electronics and high tech. In ham radio my main interests are centered around digital modes and repeater building.
Special thanks to the proof readers, Christophe F1TKE, Valentin F4HTP, Jean Mathieu F5RCT and Jeffrey W4JEW.
