Dear all,I am a bit fuzzed by the SNR values given by WSPR, in particular with strong signals. SM6BHZ is right now loud and clear, CW could be easy to copy and Gus could even give SSB a try. But WSPR is giving SNR values between -7 and +4 dB. What I noticed is that the SM6BZH signal raises the "noise level" given by WSJT7 by about 6dB (-3dB in absense of the signal, +3dB otherwise). I noticed the same effect with M0BMU some days ago. Maybe that causes the poor SNR? 73, Rik ON7YD - OR7T Disclaimer: http://www.kuleuven.be/cwis/email_disclaimer.htm |
