Standalone Arduino APRS tracker based on modified version of LibAPRS, MicroModem and SkyLabs GPS module

Arduino Uno based graphical SWR HF/VHF 160-1.25m bands antenna analyzer, plotter based on Si5351 module

Alla repeatrar i Sverige som kan köra DMR eller FM är inkluderade (källa: sk6ba.se). Även repeatrar som kör exempelvis C4FM och FM finns med. Repeatrarna är indelade distriksvis. Tyvärr finns det så många repeatrar i sjätte distriktet att alla inte får plats i scanning-listan. DMR-repeatrarna är också indelade i roaming-zoner för att få roamingen att funka på ett smidigt sätt.
