We just had an R3 class solar flare. D-layer absorption extends well up above 30 MHz. I wondered why 20 meters suddenly went dead here.
This hasn't happened in years.
@arduino Thanks for the interest in my little project. I've heard from several ham radio ops that are disabled and love the idea to get them back on their favorite mode.
Mission accomplished!
