Can anyone explain to me why qrss is necessary on 136 khz. All the activity that I have heard on this frequency is workable on normal speed cw at my qth. I could understand the use of this mode on 20 khz and below because of a possible bandwith consideration. If this was the case, there are other alternatives like MSK. Commercial stations only use the qrss method as a necessity on VLF. Maybe there is something that I have missed, like very qrp experiments, but the signals that I have heard do not indicate this. I have not seen any weak signals on qrss that I could not copy aurally. Please enlighten me please. de Mal/G3KEV
