Re: [wsjtgroup] "Shadow" traces in WSPR-X
I have seen this many times, usually with the closer (and stronger) VKs.
One Station in particular results in 8 decodes even when I have the yagi
pointed away from him.
I have coded JT-Alert-X to only alert on the primary signal and send the
highest dB report to HamSpots ignoring the lower level images.
