I have used WSPR through the past years and have always been amazed at how far one can go on so little power. I have always wondered how does it’s Signal to Noise Ratio figures I’m getting from the reporting stations mean in relation to being heard using CW. In other words, how close to a SNR of 0 do I have to be to say that if I were on CW they would hear me and not need a computer? I take it that anything on the + side of zero would make it, but when watching the waterfall and listening to my receive audio (KX3) I can hear stations that I am reporting a SNR of –10 for example. I’m running 500mw into a 40m EFHW inverted sloper and have received a few SNR 0 and +1. I have attempted to look up this information but got bogged down in the math and formulas, most of which I don’t understand.
So would a reported SNR of –10 represent a reasonable number at which the reporting station would hear me if I simply switched from WSPR to CW, all other things remain the same, or is 0 the break point? tnx de George WD0AKZ --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
