Note on Reception of Radio Broadcast Stations at Distances Exceeding 12,000 Kilometers

Aural observations of broadcast stations were made during the operations of the Byrd Antarctic Expedition, in New Zealand, and between New Zealand and Antarctica. Tables are given showing stations most frequently heard. Interference between very widely separated stations on the same frequency is mentioned. The character of fading is found to be slow and steady compared to the rapid fluttering and fluctuation of the high frequencies. The tables show that stations are heard over long paths during total path darkness on frequencies scattered throughout the broadcast band, indicating that no marked increase in absorption is present, under these conditions, through this frequency range.
