Re: LF: Re: 137kHz WSPR - what frequency?

Roger I know all about it and can decode it but I am not impressed. I can do better on CW and have worked some good DX to 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 just 6Hz (six Hertz)  - 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 software searches for decodable signals), one could fit all the users currently active on 136 and 500kHz!!

Think about it.

The majority of operators over the years prefer CW on LF and MF. These bands are narrow and we do not want the few Khz available cluttered up with data modes, especially Beacons.

Those countries with several Khz allocated like the USA have sufficient space to provide slots for all modes, different story.

I am on LF and MF daily using normal CW if you would like a QSO.

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