Games around radio: locators, DXCC, Q codes, the phonetic alphabet, bands and modes, satellites to catch, Doppler and an antenna to point, morse and pile-ups. Every game fills your QSL album. Your games, records and badges stay in your browser.
The site names a Maidenhead locator, you find it on the map or the globe. Four levels, ten zones (from the whole world to around JN18FS), hints that cost points, against the clock if you dare.
A callsign, four flags: which DXCC entity is it from? Or the other way round. Combos, streaks, three lives or against the clock, from the common prefixes to the rarest.
QRZ? QSL! 73… A code, its meaning, or the other way round — and for experts, the question (QRS?) or the statement (QRS). Combos, three lives or against the clock.
Alfa, Bravo, Charlie… Spell a callsign word by word, read spelled words back, or listen to them in the browser's voice — with some QSB for the seasoned.
The dial turns, the frequency shows: which band, from 160 m to QO-100? Then which segment of the band plan, or which exact use: FT8, the ISS, beacons… (IARU Region 1).
CW, FT8, RTTY, SSTV, packet, WSPR… A few seconds of signal made in the browser, its waterfall scrolling: by ear, which mode? With some hiss if you dare.
The sound of a real pass slides with the Doppler effect: turn the knob, keep the note on 1,000 Hz. VHF, UHF that flies, SO-50 in FM, and QO-100 to breathe.
Every right answer, in every game, sends you a QSL card. Fill the album and the world map, open the bureau's envelopes, trade your doubles, earn WAC, DXCC, WAZ.
The site keys in morse, you type what you hear: callsigns, words, Q codes. From 12 to 40 WPM, adaptive speed, noise and QSB, and the Koch method to learn.
