PSKReporter · WSPR · Reception reports
Where am I heard?
Call CQ on FT8, FT4, PSK or CW, or run a WSPR beacon, then enter your callsign here to see which stations decoded you and reported it, on a map and in a table, with distance, band and signal-to-noise ratio. Works for any callsign, any country.

How it works
PSKReporter collects automatic reception reports from thousands of receiving stations running WSJT-X,
JTDX, fldigi, CW skimmers and similar software. This page asks its public retrieval interface for reports of
your callsign as the sender. PSKReporter asks clients to query no more than once every five minutes,
so this page enforces that on your device and shows a countdown. It returns at most 24 hours of history, and this
page asks for at most 500 reports; when that cap is hit only the newest reports are shown.
The query runs as a JSONP script from retrieve.pskreporter.info, the method its developer page documents.
WSPR spots come from wspr.live, a public database of every spot reported to WSPRnet. wspr.live is volunteer-run and free for non-commercial use. Mode names (WSPR-2, FST4W-120 …) come from its mode table.
Positions are the centres of the Maidenhead locators the stations reported themselves (a 6-character locator is about 9 × 4.6 km at mid latitudes, a 4-character one about 180 × 110 km), so distances are approximate. Your own position is the locator most often reported with your spots. Distance is the WGS-84 great-circle (short path) distance between locator centres (Vincenty). Stations that reported no locator are listed but not mapped.
Bands are worked out from the reported frequency using the US amateur band edges in 47 CFR 97.301 (3.5–4.0 MHz is shown as 80 m). For WSPR spots outside US bands (for example 60 m in Europe or 4 m), wspr.live's own band field is used; anything else is “other”.
SNR is as reported by the receiving software, in dB in a 2500 Hz reference bandwidth for WSJT-X modes and WSPR. The map colour bands are only a visual guide. Reports are crowd-sourced raw data: expect occasional duplicates, wrong locators or false decodes. Absence of reports doesn't mean nobody heard you, only that no reporting receiver did.
