Radio wave propagation describes how radio waves travel from one point to another, classified as ground waves, skywaves, and free space propagation. Ground waves propagate over the earth's surface in low/medium frequencies, bending around obstacles but limited to short ranges. They enable AM/FM broadcasting and military submarine communication.

Define the SWL contest 2026 as an event for monitoring a variety of languages on _medium wave_ (MW) and _shortwave_ (SW) AM radio stations. Participants can utilize either traditional radio receivers or _WEB SDR_ platforms to log their findings. The contest encourages the use of both analog and digital methods to maximize the diversity of languages captured. The contest rules specify that entries must include detailed logs of the stations received, including frequency, time, and language identified. Logs should be submitted in a standardized format to ensure consistency and accuracy in judging. The use of WEB SDR is particularly highlighted for its ability to access distant stations that may not be reachable with local equipment. The contest is open to all SWL enthusiasts worldwide, with a focus on European WEB SDR access. The event aims to foster a deeper understanding of global broadcasting patterns and linguistic diversity. Participants are encouraged to explore various bands within the MW and SW spectrum, enhancing their skills in signal identification and language recognition. The contest offers a unique opportunity to engage with the global SWL community and share insights into the art of listening.
