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.

Yes it is frequency, time and location dependent. If you haven't already,
look up a LUF/MUF calculator and try it out. Inputting the solar flux data,
your location and the location of the broadcast transmitter gives you a time
graph showing the LUF (least useable frequency) and the the MUF (maximum
useable frequency). Simply put, the MUF shows the highest usefull frequency
for tranmissions from that location at any particular time. If your desired
station frequency is higher than that, forget it. Also, if the LUF is
higher than the MUF, you wont be hearing anything from that location until
solar conditions (or the time of day) changes. It's an informative way to
see how the solar conditions, time of day and propagation path affect what
you can hear.
