This app answers the two basic questions facing radio amateurs:-
Which band shall I use ?
Where shall I point my beam ?
It will be of interest to anybody who wants to study radio propagation and the ionosphere.
This app plots real-time radio transmission paths on a world map which may be centered either on the Atlantic or the Pacific and incorporates a background display of the ‘greyline’ or terminator.
Paths of single stations may also be viewed.
In addition there is an Aurora plot option and display of Space Weather indexes.
WSPR (Weak Signal Propagation Reporter pronounced ‘whisper’) is designed for probing radio propagation paths using low-power beacon-like transmissions. WSPR signals convey only a callsign, Maidenhead grid locator and power level. Receiving stations with internet access automatically upload reception reports to a central database.
