[78-L] Acoustic v. radio

[Kristjan Saag]

Not that it matters much for sound quality, but the 9 kHz spacing 
between stations in the European medium wave band didn't take place 
until the 1928 IBU Conference in Brussels. The original spacing in 
Europe, decided upon in Geneva 1926, was, like in North America, 10 kHz.
So 9 kHz is basically outside the scope of the acoustic era in recording.
Moreover, although the 9 kHz spacing was agreed upon it wasn't generally 
effectuated until after WW II, and some countries never bothered to 
follow the advice anyway.
