The bandwidth of an FSK WSPR transmisson is just= 6Hz (six Hertz)=A0 - hardly "cluttering up" the bands= me thinks? Transmissions are sent in time slots, so that 10 users could= share a single 6Hz slot and in, say 200Hz (the band slot the WSPR softwar= e searches for decodable signals), one could fit all the users currentl= y active on 136 and 500kHz!!

Think about it.

The majority of operators over the ye= ars prefer CW=20 on LF and MF. These bands are narrow and we do not want=A0the few=A0Khz=20 available=A0cluttered up with data modes, especially Beacons.
Those countries with several Khz allo= cated like the=20 USA have sufficient space to provide slots for all modes, different story.= =20
I am on LF and MF daily using normal= CW if you=20 would like a QSO.

What is the dial setting frequency (USB) for 137kHz WSPR= and=20 are there any particular date/times when WSPR is being used? I'd lik= e to=20 listen.
