New to amateur radio?
You can pass the exam in a few weeks with no prior knowledge. Four steps to your own callsign:
Six topics, the same as in the menu above. If the terms are new to you, each one is explained.
From first interest to your own callsign: what the exam asks, where the next date is, how to study and which local club is near you.
On air: FT8 and JS8 with the radio on your USB port, control your own radio remotely, listen to networks, log in contests.
What's on the air around you: repeaters with line of sight, sites with webcams, live APRS stations, parks and summits for portable operating.
Long-distance contacts: who's on the air right now, where your signal lands, which bands are open and when the satellite passes.
Check antenna and radio before you go on air: measure the match, check harmonics against the limit, program memory channels, calculate.
Official and club data, synced several times a day: who holds a callsign, which country a prefix belongs to, what's allowed on each band and what you may do abroad.
Callsigns from the Bundesnetzagentur (BNetzA, German regulator), repeaters and local clubs from the DARC, area boundaries from BfN and OpenStreetMap. Synced several times a day, every source named with licence and date.
No third-party servers for fonts or maps. For use on the go you can store the band plan, repeater list, glossary, exam dates and calculators on your device, around 1 MB, only when you press the button.
