Hello Genosse = Roman,

NAA should be centered exactly at 24 kHz, like DHO38 is at 23= .4 kHz. It
can have strong QSB and appears only a few hours per day. He= re it
appears arround 4 UTC these days.
My grabber and all webpages = do not work in the moment due to a webserver
problem which may be solve= d just next week...
These narrow traces are something else, NAA always l= ooks like DHO, about
200 Hz wide.
