I was listening to radio Australia today on 21740 until 00:00 UTC
when they switched to 17795 and 17715. The 16 meter signals are very
weak and noisy today. They usually come in quite well on both
frequencies with 17715 a little stronger most days.

21740 was very strong today.

I see we have a solar flare in progress.
