4 mar 2024 · From Low Frequency (LF) to Very-High Frequencies (VHF), each band has distinct characteristics and propagation conditions. Frequency allocations vary by country and ITU region. Understanding band usage and regulations is crucial for effective communication among ham radio operators worldwide.
This map shows real-time radio propagation from stations operating on 11 bands between 1.8 and 54 MHz in the amateur radio service. The display shows worldwide activity from the last 15 minutes and is automatically updated about every minute.
For amateur radio uses (HamRadio), World globe and maps, with live/realtime MUF maximum usable frequency, foF2 and Aurora Borealis layer. Tell distances, directions of antennas.
This map displays the live radio activity of ham radio stations using 11 amateur radio-designated bands between 1.8 and 54 MHz. The display automatically updates every minute or so to reflect activity from the previous 15 minutes around the world.
Radio amateurs use a variety of transmission modes, including Morse code, radioteletype, data, and voice. Specific frequency allocations vary from country to country and between ITU regions as specified in the current ITU HF frequency allocations for amateur radio. [1]
This live HF (high-frequency) propagation map (chart) is a real-time tool that visualizes the current conditions of radio wave propagation across the globe.
only the 2.8 kHz centered around each of these frequencies. The FCC changed one frequency effective March 5, 2012 and now grants amateurs access to channels centered on 5332, 5348, 5358.5, 5373, and 5405 kHz. The last channel, 5405kHz is common to the UK amateur 5-MHz experimental band plan.
