It is normal that you see a few carriers of the Alpha signal because it is a pulsed/keyed signal. This can be confusing in the first step. Just increase the resolution more, then the other lines will disappear :-) (They will not fit in the spectrogram any more then...).
The center line is at 1904.7619 Hz. 424 uHz is a good bandwidth for observations, for example.

Thank you very much for the test Domenico !
 
I have been playing with Markus EbNaut utilities for SpectrumLab this weekend and just needed a signal in LF :-)
 
Anyway I'm not very confident to get decodes. Using virtual audio cable to feed SL the sample rate is 44100Hz
but when I zoom at mHz FFT-bin of a steady carrier like Alphas for example, I see a group of carriers, not
a single signal. I suspect VAC samplerate is not exactly 44100 or there is other kind of problem with this software
 
This don`t affect WSPR or Opera decodes, but may be EbNaut will not admit it. Let's try it
