I have learnt, WSPR sounds like a slightly rough CW and is transmitted in
4min-blocks. <<<<<
Dennis , That may not be wspr , wspr tx time is 120 seconds locked to the
exact time , with the start time on the 00-00
by sound its like a very slow narrow shift psk signal .....but it is only
one carrier changing frequency with no breaks in the 120 second
transmission
The software may be downloaded :-

As long as the pc clock is close it will decode ok ....if the pc is not
on the www , multipsk has a pc clock set facility that use the mf time
signals
