Wondering what to do with your new Amateur Radio license?
This email provides you with articles and advice from experienced hams to help you get active and on the air.

Here Comes the Sun


Why do hams care so much about solar cycles? The answer starts about 50 miles above your head in the ionosphere, where ham radio signals are heard hundreds, or even thousands of miles away. Learn about Cycle 25 and why hams are happy that it's here.

Space Weather and You

Just as with weather here on Earth, it is a good idea to keep informed about space weather conditions and forecasts. If you are looking at current space weather data, pay particular attention to the Solar Flux Index, K-index, and A-index as discussed in this article.

What does the new solar cycle have in store for the HF bands? Propagation expert Carl Luetzelschwab, K9LA, tells us what to expect in this episode of the On the Air podcast.

Our Active Sun

Did you know the sun has an enormous impact on amateur radio? Unless you are operating at very low frequencies or ones above 144 MHz, solar winds, sunspots, solar flares, and coronal mass ejections can impact your amateur radio activities. Read more about how in this article.

Solar cycle — The cycle of sunspots that rise from a minimum number of sunspots to a peak level, and then back down to minimum over a period that has long been believed to span 11 years, though new research suggests it may be longer. Propagation on the high-frequency (HF) bands varies along with the sunspot cycle.
