Real-Time Solar Weather Impact on HF Radio Communications

Explore the dynamic effects of solar weather on HF radio communications with real-time data and comprehensive explanations.

While many solar weather sites provide various information, few are exclusively dedicated to HF communications. SolarCdx.com is your go-to source for real-time solar weather conditions and how they affect HF in real-time because ham radio is now.

Our focus is on the HF spectrum (0-30 MHz), though many concepts and instruments can be applied to other frequencies as well. Solar activity plays a crucial role in shaping HF radio propagation, often leading to unexpected DX openings and sudden disruptions.

Events such as solar flares and coronal mass ejections (CMEs) can significantly enhance signal strength and extend communication distances, sometimes at unusual hours. However, they can also cause signal blackouts, rendering bands temporarily unusable.

We extend our gratitude to the sources that make this possible: NASA, NOAA, and USGS.

So, should you turn on the radio or just enjoy a pizza? We’re here to help you make that decision.

Using the site

You might see this orange bar on pages in our site. It’s important, that’s a ‘HAMSplainer’. It splains things for us older hams. 

You can click on the tabs like “Hams”,”Geomag”,etc…  Every gauge or instrument has a different meaning, so the tabs change. There’s always a “HAMS”, “SCIENTIST”, and “TLDR;” (too long;didn’t read– for you impatient types).
