Wspr charts. 4 days ago · WSPR Spots CSV/XML download disabled until fixed WSPR is a digital radio communication protocol designed for weak signal transmission. Shows which areas of the earth are in daylight. Each WSPR transmission carries encoded the originating station's callsign, Maidenhead grid locator, and transmitter power in dBm. org and allows public access to the data. WSPR-X is a new experimental version that includes the slow mode WSPR-15. Frequencies WSPR Maps with a diffence. WSPR uses frequency-shift keying and forward error correction to reliably send data tens or thousands of miles with just a few milliwatts of power. This page allows you to do analysis on the real time wspr spot data. WSPR Frequencies Band Dial Band Start Band End 160m 1 836,6 kHz 1 838,0 kHz 1 838,2 kHz WSPR Frequencies Nov 23, 2009 · WSPR (pronounced "whisper") stands for “Weak Signal Propagation Reporter. Red = weak, yellow = mid, green = strong signal. . Powerful WSPR analysis tool with live maps, heatmaps, charts and a visual SQL query builder. New Heat Map. May introduce minor rendering artifacts on some systems and can affect heatmap appearance (dark overlay). Explore propagation and filter data by callsign, band, time and any supported field. Free for non-commercial use, at users own risk, for the Amateur radio WSPR community. We would like to show you a description here but the site won’t allow us. The WSPR mode is designed to probe potential radio propagation paths with low-power transmissions. 32 and 64 Bit versions supported. Map your own spots hour by hour or for 24hours. Advanced WSPR propagation analysis using interactive maps or user callsign anchoring to evaluate HF band behaviour by distance, region and time. Modulation is by narrow-band FSK. In MEPT transmissions, the radio becomes a beacon that transmits for just under 2 minutes, transmitting callsign, locator and power information. Open WSPR Visualization in New Window. List of currently available WSPR tools for viewing, Map display, and analysis - updated at Dec 2019 - in addition to the WATT tool. This interactive 3D Earth model shows real-time WSPR propagation paths between amateur radio stations. Shows Maidenhead grid squares colored by activity level. Pre-requisites: Microsoft Excel 2010 or higher. The database contains all spots ever reported to wsprnet. Maps for long path, global VHF+, QRP Map, Alt WSPR Modes, Moving beacons, False decodes, Globally active beacons and reporters and more. It is available in WSJT and WSJT-X. This website allows you to access and visualize more than 5 Billion records in the WSPR Database, reaching back to 2008! WSPR is a perfect tool for long-term Propagation analytics, but also convenient for a quick check of YOUR HF Propagation conditions. Features include: The visualization opens in a new window/tab and runs independently of this Quarto site. Mar 17, 2025 · WSPR (short for Weak Signal Propagation Reporter) is an amateur radio beacon protocol. WATT WSPR Analysis tool Reporting, investigation, spreadsheet filtering, propagation analysis, ad-hoc charts, and timeline animation/replay of WSPR traffic. It is designed to act as an incredibly weak signal beacon, used for examining amateur band conditions. It utilizes 2 minute long transmission times and provides callsign, location, and power information. ” The WSPR software is designed for probing potential radio propagation paths using low-power beacon-like transmissions. WSPR-15 uses 15-minute T/R sequences, rather than the standard 2-minute sequences; at MF and LF it is 9 dB more sensitive than WSPR-2, decoding signals as weak as -37 dB in the standard 2500 Hz reference bandwidth. WSPR Weak Signal Propagation Reporter WSPR (usually pronounced “whisper”) is a software application that uses the transmission mode MEPT-JT (Manned Experimental Propagation Transmitter – Joe Taylor). ixrtq khvp ujbbvo jwodyca ysttf mms fyfhd bcguj bfnoo wsgqnc
