Mackay-ITT

Mackay/ITT produced a broad line of marine radio gear which found much use on the high seas. However, it was not as successful on the Great Lakes and Inland Rivers as RMCA or Lorain.

The Type 128AY (below), Type 128AW, Type 128AZ and the U.S. Coast Guard RC-123 are all essentially identical in appearance and have only slight internal differences.

The 3001 below is an excellent Mackay regenerative receiver. They were designed for marine navigation use, and were built with the best available components. It has four bands, 15-41, 37-105, 95-250 and 240-650 kc. Controls are left to right, antenna trim, antenna switch, power, bandswitch, regeneration, RF gain, AF gain and speaker/phones. Tube complement is 35Z5, ballast R22, 6J5, 6SJ7 (2), 6G6 and 6SK7. Dimensions are 17"w x 9.5" h x 12" deep.

Federal Telephone and Radio Corp. was a manufacturing associate of I.T.&T. I believe their gear was intended for the high-seas, and I don't know of any use of it on the lakes or rivers. The image is from this article on the World Radio History site. I believe the receiver in the upper section, lower right, is a Mackay Type 3001. This console is similar to the Mackay console pictured above.
