Roger I know all about it and can=A0d= ecode it=20 but I am not impressed. I can do better on CW and have worked some good DX= to=20 date especially X BAND.
I tx on 500 and listen HF like 7 Mhz.=

Mel, et al,
The bandwidth of an FSK WSPR transmisson is=20 just 6Hz (six Hertz)=A0 - hardly "cluttering up"= the bands me=20 thinks? Transmissions are sent in time slots, so that 10 users could sha= re a=20 single 6Hz slot and in, say 200Hz (the band slot the WSPR software searc= hes=20 for decodable signals), one could fit all the users currently active<= /u> on=20 136 and 500kHz!!

Think about it.

The majority of operators over th= e years prefer=20 CW on LF and MF. These bands are narrow and we do not want=A0the=20 few=A0Khz available=A0cluttered up with data modes, especially=20 Beacons.
Those countries with several Khz= allocated like=20 the USA have sufficient space to provide slots for all modes, differen= t=20 story.

What is the dial setting frequency (USB) for 137kHz= WSPR=20 and are there any particular date/times when WSPR is being used? I&#= 39;d like=20 to listen.
