"Seems Like Radio is Here to Stay" -- Old Radio, Radio Magic
The first 12 minutes of this podcast are pretty good. I think it captures well the wonder of radio -- magic carpets, signals taversing the Himalayas and all that -- but the presentation is kind of confused. The PRX podcasters keep saying that it was recorded in the 1930s, but then we hear references to the Nuremburg trials and the possibility of sharing the atom bomb. So there is some confusion in the presentation.

Can anyone find the original recording from the 1930s about the wonder of radio, without the references to things that happened in the late 1940s?
Thanks to Rogier for sending this to me.

Dave W2DAB's NEW YORK CITY Homebrew SolderSmoke Direct Conversion Receiver. Manhattan Construction IN MANHATTAN! FB!
Dave obviously did a beautiful job on this receiver, and it sounds great. Dave's reception is hampered by his high-rise location -- he is currently limited to the use of a mag loop. I thought about suggesting that Dave take his receiver down to Central Park or to the banks of the East River, but I worry that this device might be too much even for the famously tolerant residents of the Big Apple.
By the way, that station Dave heard was Percy, KF2AT, right up the road from him on E 106th Street.
