Radio, radio!
A tour of WBCQ in Maine from April of last year. WBCQ is a new shortwave station:
Bonus #1: We went on a virtual tour of the Early Television Museum. How about one of the Antique Wireless Museum?
Bonus #2: Another tour, this one of WLW in Mason, Ohio. WLW at one point was transmitting at 500,000 watts (between 1934 and 1939). They were forced to drop down to 50,000 watts, and still use that power level.
