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. Best regards Roger G3XBM 2009/8/27 mal hamilton <[email protected]>
