These frequencies are used by amateur (ham) radio . Space weather impacts radio communication in a number of ways. You can control some factors like antenna location and transmit power. Instead of speaking of propagation in terms of ionospheric layers, that nobody can really materialize, amateurs and listeners are used to speak in terms of frequencies or bands. Geomagnetic storms reaching the G1 level are likely. From 5 to 9: Very bad conditions for 10,12,15,17,20 meter bands. The maximum usable frequency (MUF) is the highest frequency that, with a probability of 50% of the time, can be used for radio communication between two points at a specified distance (but not necessary in all directions) via refraction by the ionosphere. Repeater Status. It can achieve worldwide radio coverage when propagation conditions are . At frequencies in the 1 to 30 mega Hertz range (known as "High Frequency" or HF radio), the changes in ionospheric density and structure modify the transmission path and even block transmission of HF radio signals completely.

The HF Bands The 10 ham High Frequency bands (actually 9 HF and 1 MF band since 160 meters is considered part of the Medium Frequency part of the radio spectrum) were chosen to take advantage of the varying propagation characteristics of the Ionosphere. The blue line on the lower graph shows the aggregate irradiance level in the entire band of 1-500 angstroms (from X-rays through ultraviolet), and this wavelength band is of considerable importance to hams, as it is also responsible for about half of F2 layer ionization, improving conditions in the upper HF bands (20m.-10m.) A PC Windows program that continuously identifies which NCDXF/IARU DX beacon station is currently broadcasting on any of the five HF Amateur Radio bands (20, 17, 15, 12, and 10 meter) bands.The current beacon call sign is updated and displayed, along with a flashing Status LED, on a relief map of the world. Understanding HF propagation conditions and predictions are important for your contest strategy to maximize the points.
