From the collection of Robert DeBow, whose uncle served on submarine chaser SC 299, are several excellent and rare photographs of the radio room.
The radio room on SC 299. On the left is the radio telephone switchboard, Western Electric CW 938.
Next to that, on the shelf, is the National Electrical Supply Company's CN 113 receiver. (See Mike Schultz' page on the CN-113 for details.)
Below that is a Western Electric CW-930 microphone. (See this page.)
Mike notes that the item behind this might be a multiple crystal detector unit, such as the Lowenstein model SE-183A or Wireless Specialty.
