Special Event Stations - K5A, K5R, K5S

We are operating the special event stations K5A, K5R and K5S from Saturday, September 28th through Sunday, October 6th, 2024 to promote innovative, free and open amateur radio software.
During the event we honor the 2024 award recipients Jakob Ketterl (DD5JFK) for OpenWebRX and Marat Fayzullin (KC1TXE) for OpenWebRX+.
As part of the special event we encourage people to submit nominations for the 2025 Amateur Radio Software Award.

The operating schedule should be taken as a guide where to find the special event station. Based on band condition and other unforseen events operations may change. Most likely some operations will occur in addition to the posted times. Thanks for your understanding.

Operators are the Amateur Radio Software Award committee members Claus (AE0S) for K5A, Kun (N7DMR) for K5S, and Rich (K0EB) for K5R.

For SSB we'll try to operate in the following frequency ranges:

If you want to save postage, a single SASE for all stree stations is OK. Please still include a separate card for each station (K5A/K5R/K5S) you made contact. Multiple modes/band for the same station do not need a different card. Send the cards and SASE to one of the three addresses you worked. Please note that this will delay the mailing of our QSL card to you.
