Work Description:
This shows a broadcast station with a number of pieces of equipment which we (the Department of Physics) still have and use occasionally in 1973. Probably in the northeast basement of Hale - however, the picture shows a wooden floor while the Hale basement has cement. The high window sills can only be in the basement. It may be that the original basement floor was wood and the cement was added later. The window spacing could only be in the 1910 additions on east and west and it does not seem to match any of the west windows. The negative is badly eroded at right. The large cage at the left looks like a homemade capacitor of five large parallel metal plates. Under the left end of the table is a large variable resistor with two knobs and an elegant marble face. On the left end of the table is a large high voltage transformer - to its right is a large copper tubing coil topped by an adjustable spark gap in a spherical globe, while two precision meters are on the table in front of the coil. The operator's left hand is on what appears to be a variable inductor and over a wooden pushbutton - like a door bell button. To the right are an adjustable cylindrical capacitor, a variable parallel plate capacitor, two crystal detectors, a telegraph key, and a post office type variable resistance box. It looks like relays and repeaters in the window.
