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 :-)

Subject: Re: LF: 24.0 kHz sig - NAA?
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?).
