This is the April 1930 issue of Radio News. It has articles on the relationship between sunspots, weather and radio reception, tube manufacturing processes, early car radios, short wave use on movie sets, Amos and Andy, and much more. I particularly liked the article on sunspots. It aired a complaint that because of sunspots, one station could only be heard 600 miles away. In DXing today 600 miles is a respectable showing for any commercial station. These early-era radio articles are about completely outdated, archaic technology but remain interesting from a historical perspective. It's 100 pages chock full of radio arcana.
