01 / How it works

Three steps between contact and rating.

01

Tune in

Connect to VarAC as you already do. Chess appears in the next update — no extra software, no separate network.

02

Play the game

Move by move, over the same link that carries your messages. Finish the game and note the result.

03

Transmit the log

Upload the PGN here, both callsigns and the result. The VarAC rating for each side recalculates immediately — or vmail the result to a tournament director and they'll log it for you.

No internet at the radio? Both operators can vmail the agreed result to a tournament director instead — they'll enter and confirm the game on your behalf.

Ready to log a game?

Sign in with your callsign, upload the PGN, and the rating maths happens for you. Every logged game is public and replayable.

02 / Rating bands

One club, four bands of the dial.

Your rating places you in a band. Standings are published per band, so a newcomer is never lost in a list of grandmasters.
