This inability to decode was not limited to Digirite. I used the WSJT-X
with N1MM solution.
I wondered if there was almost a de-sensing effect from generally full
waterfalls. Whether as it were the soundcards were not swamped with signals
making decoding difficult.
I don't know the tchnical terms but many many strong signals arrived here
and stations I normally work with ease on the regular week=day band
conditions were not copying me and even though they were +NN dB signal
levels were decoding only intermittently.
At my end I just felt like either rig but more likely soundcard was
essentially "overloaded" or "swamped" with signals.
I am curious as to the conclusions.
72 and thans for the many QSO's
