K0IRO Summer of Simplex

Welcome to the Summer of Simplex!

Much like the repeater contest, we have a chance to embrace simplex communications and get on the air without the help of a repeater. From June 1st through August 31st, log all of your simplex contacts and activities — every QSO counts!

And here's the best part: Ham and GMRS simplex count equally. Whether you're running 2m SSB, chatting on 146.520, or hitting a GMRS channel across town — it all goes on the board. Let's have some fun with it!

📝 How to Participate

After each simplex contact, head to the Submit page and log it. Enter your callsign, the callsign you worked, the mode, frequency, and whether it was a POTA activation. That's it — your score updates automatically on the Leaderboard.

Contacts can be logged any time during the contest period. There's no limit to how many contacts you can submit — every simplex QSO counts!
