Dear Jim, LF, that is a clear evidence of a soundcard sampling rate error. I am quite sure that all timing in the WSPR software is derived from the sampling frequency and, if memory serves me, the WS
Dear Graham, LF Group, Remembering what I said jokingly to RA3AGC a few days ago about visually verifying a spectrogram trace of a WSPR signal, and the discussions of merits of WSPR vs QRSS, I though
Yes, I also notice good decodes at low S/N ratios, during downward fades, but nil decodes when the signal is stronger than about -6dB of strong signals due to soundcard sample rate problems, and in t
Gary.. Must be a dx version of wspr I think its a combination of the mother board , old isa/pci/agp p111 1.1 ghz and may be the 'new to me' sound card .. just checked and no decodes to night off air
Dear Johan, Graham, LF Group, If the shorter frame length is due to a sample rate error, there should also be a corresponding upward shift in the audio output frequencies. If we take M0LMH's figure o
Hi LF, Interesting observation. Tonight up to now I have only had one decode from Graham’s WSPR & that was when I had a high level of broadband noise here masking the signal. I have just insert
