The National Voice of America Museum of Broadcasting has a great web site.  They have assembled a treasure trove of documents about VOA, Powel Crosley, Jr., WLW Radio, Amateur Radio and the Gray History of Wireless Collection.  Check it out:

Power Amp techies will enjoy the Institute of Radio Engineers (IRE, predecessor to the Institute of Electrical and Electronic Engineers, IEEE) paper concerning the design and operation of the 500kW transmitter at WLW.  The power required to just light the filaments in the RF section and Modulator was 33V # 4,150A….nearly 137kW!

 

As I mentioned the VOA is still active with streaming services,  Check it out:

I enjoyed the meeting and appreciate everyone’s attendance.  Stayed tuned for the date of the September meeting in Russellville.
