    Foundations of Amateur Radio - Episode 88

    The pimples on the Sun that erupt and make a mess are called Sun-spots and they make it possible for you to use your Amateur Radio on HF for long distance communication via the ionosphere. How does this actually work and what is a Sun-spot actually and why are Sun-spot numbers not the same as the numbers of dots on the Sun. This week I investigate how getting Sun burned is like heating the ionosphere.

    Foundations of Amateur Radio is a weekly podcast about anything ham radio and can be downloaded from and fond on iTunes by searching for VK6FLAB.

    Thank you for your kind and sometimes provocative emails, unexpected, fun and enlightening, keep 'm coming -

    Interesting sun spot article - thank you. Perhaps a follow-up piece providing some basic pointers in interpreting solar/geo indices as propagation indicators would be useful to HF operators - particularly newer ones, and especially as we head into a solar minimum.

    Best Regards,
