ORIGINAL MESSAGE:
"Robert11" wrote in message ... Hello: What's a "good" value for the SF Solar Flux values reported for general SWL (30 MHz and below) ? Is it freq. dependent ? How ? Thanks, B. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ It would take hours to really answer your question fully, but I think I can help: For most hams, when the flux gets above 100, things are picking up. Above 125, you'll hear comments about how great the bands are. Above 150, you can do DXCC in a week running QRP. Above 175, you'll ask the wife to call in sick for you so you can chase DX. Above 200, you won't have to call in sick anymore because you quit your job. How's that? :-) Bill, W6WRT |

In non technical terms the K and A averages subtract from the 'goodness' of the flux. Low K, 1 through 3, indicate good propagation. High K, 5+, indicate poor propagation good for taking a nap.. A values below 4 are good, 5 to 10 fair, 11+ are take a nap. Now if the A index hits 20+ take a long nap. Seriously, Flux above 150 suggests very good propagation when K and A are low. Flux below 100 and high K and A suggests propagation is poor. |
