One log for twenty operators — a platform for amateur radio awards

The idea for this platform is mine; I laid down the architecture back in 2025 and wrote it myself.

On 6 March 2026 I showed it running for the first time — from my own laptop, through ngrok, with a link that lived until midnight. Even then it kept a shared log, accepted contacts from WSJT-X over UDP, imported ADIF with duplicate checking, and had separate dashboards for hunters and for organisers. The next evening the bridge for digital modes appeared — for Windows, Linux and macOS.

In April, seven weeks after that demonstration, the special callsign EN40CNP was on the air for the 40th anniversary of Chornobyl. Two weeks, 1565 contacts, several operators — and the whole log was merged by hand: the platform was not yet ready for real use. Vitalii, UT0UI, put the experience most precisely: “merging logs after the fact by hand is a right pain”.

By August it was ready. What follows is what came of it: the platform uahamaward.com, on which the “35th anniversary of Ukraine's independence” award made 17,387 contacts in 31 days, and not one of them was merged by hand — neither during the month nor after it.
