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.
