![]() ![]() The map indicates SNR levels with three different per-band shades: SSB (SNR > 10), CW (SNR > -1), orĭigital modes (which can decode down to an SNR of about -28).Ī VHF Propagation Map shows real-time propagation on the 2 meter band. SNR can be used to determine if a particular path supports certain modes like Some of these sources provide signal-to-noise ratio (SNR) information. On this map, MUF can be considered the maximum used frequency, since the display is based on real-time data.ĭata for the map is gathered from several online sources: WSPRnet, Reverse Beacon Network (CW, FT4, FT8), and DX Cluster. Maximum usable frequence (MUF) is the highest frequency that supports communication between two points. JavaScript must be enabled to use see the real-time graphics. The display shows worldwide activity from the last 15 minutes and is automatically updated about every minute. Government of Telangana, Grid Controller of India Limited. ![]() This map shows real-time radio propagation from stations operating on 11 bands between 1.8 and 54 MHz in theĪmateur radio service. Percentage, Piece-work, PPP-BoT-Annuity, PPP-BoT-HAM, PPP-BoT-Toll, PPP-BoT-ToT, PPP-DBFO. ![]()
