This page shows some statistics on 6m band FT8 signal, and the antenna is a simple dipole on the balcony in Chengdu, China.
The upper histogram shows the number of decoded messages received in a time period, with the color shade representing the average SNR value. A number of -1 indicates that the monitor station is temporarily offline.
The world map below shows the distribution of signals in each country during the time period selected in the upper window (according to callsign).
Thanks to BH8DDA for correcting the map data.
Disclaimer: Map data is taken from public free sources on the Internet, and its outlines are highly compressed and censored, do not represent the actual administrative division of the country, and are only used here as a rough indication of geographical distribution.
