Read what Markus wrote there.

May be he describes exactly what R6LDD's image shows.

In the mid 60's I wished that my receiver (BC-453/4/5) would reach 24 kHz.

Still works and still wish; that much stayed the same :-)

How times change. In the late 1960s I received NAA on a hot summer afternoon
in the town of Harlow, about 30 km north-east of London. The antenna was an
L about 80 m in length and the receiver was an ex-Navy unit which covered
from 15 to 750kHz (B29?).

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. Here 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 solved just next week...
These narrow traces are something else, NAA always looks like DHO, about
200 Hz wide.
