Thanks Alan, it's clearer now in my mind.
I had tried to install SparkSDR several times during the last year and always failed for an unknown reason. This morning it installed like a charm!
Well I wanted to use Fldigi with Quisk to make CW from the keyboard and have it decoded by Fldigi while earing the sidetone. I did not find a way to do it and asked in the
groups.io/g/n2adr-sdr,
Mirek Kolodziej, so5wd answered to me that "
FLDIGI I am using with SparkSDR and I can do CW as you need.", the reason why I tried again to install SparkSDR and succeeded.
Living in a steel reinforced concrete condominium, a true Farady cage, I plan to use my station as portable (HL2 - SparkSDR - Alexloop) mainly in CW and SSB and also in FT8 but I'm not sure about the interest of WSPR-X, I loved before PSK31 but it looks like being quite outdated currently?
Thans again for your fine business!
