45443 in Wyomissing.

A history of radio in the United States.  At about 2004 the timeline is 1928 or so.

Via K2SDR WebSDR.  S8 to S9 signal level with minor fades.  Good quality audio, nice wide signal and strong carrier.

2037 - Hindenburg disaster report audio "oh the humanity!"
2039-2041 - Audio gone.  Carrier keying on and off.  Weaker carrier popping up in the sidebands.  Signal is still a solid S9.  Data bursts on frequency at 2042 and then the carrier disappeared.
