12m challenge concept
“The aim of the challenge is to promote use of the 12m band for SOTA QSOs”
10m/6m challenge concept
“This will be a challenge to make contacts on 6m and 10m.”
Flavours challenge
“Like in the past we want to encourage use of parts of the spectrum, and operating modes that are generally less represented in SOTA, but keen to maximise participation by making the Challenge both diverse and inclusive.”
2024 10m challenge concept
“The aim of the challenge is to get everyone using 10m a lot.”
A 15m challenge would be identical in concept to all the others.
