"According to me, not to all of those radio frequencies simultaneously, and if there was noise blocking transmissions, the primary radios should show that and it should be directly audible on the simplified shortwave."

"According to me, the zero-warning first front of a solar flare does not block all of those radio frequencies simultaneously.  Furthermore if there was noise blocking transmissions, the primary radios should show that in indicator lights and it should be directly audible as noise on the shortwave."
