Index-Recherche im "Radio.Magazin" 1922-1930 zu : >>> WBBR <<<
4 Treffer in 4 Dokumenten, erste Nennung:  
RadioBroadcast-Vol-05-1924-08.pdf   Seite3
Hier findet man es "unheimlich", das manche Sender auf ihren 
kurzwelligeren Harmonischen teilweise besser zu empfangen sind als auf 
der Grundwelle........

"....HOW THE HIGHER FREQUENCIES CARRY
THE possibilities of these very high frequencies are uncanny. Using a 
small regenerator with a ten inch antenna (needless to say, indoor), the 
writer has copied foreign low power stations operating in the 
neighborhood of 3000 kilocycles. Distant amateur stations have also been 
received on high harmonic frequencies which could represent only a small 
fraction of the already low power radiated on the fundamental. Dr. 
Greenleaf Whittier Pickard has had similar results in a room at the 
Commodore Hotel in New York City. Due to the freak element in these 
frequencies, distant broadcasting stations are often received much more 
consistently and loudly on their harmonics. KYW, at Chicago, is often 
recorded at Newton Centre, Massachusetts, on the 8th harmonic at greater 
intensity than on the fundamental. Doctor Pickard, in his study of short 
and long period variations, has made these extremely short waves 
photograph themselves; and has no unusual difficulty in obtaining a 
beautiful graph of the variations in >>> WBBR's <<< sixth harmonic at 
7500 kilocycles. Fig. 1 shows a most remarkable photograph, which the 
author is reproducing with the kind permission of Doctor Pickard. This  
masterpiece of laboratory finesse shows the simultaneous variations in 
strength of KDKA's fundamental at 3000 kilocycles (already far above the 
region of conventional broadcasting) and its third harmonic at 9000 
kilocycles....."

Eine wirklich schöne Aussage: "...THE possibilities of these very high 
frequencies are uncanny. "  /  "Die Möglichkeiten dieser sehr hohen 
Frequenzen sind unheimlich"..............
