PATENT YEARS ON NAMEPLATES

Some of the nameplates on Marconi equipment contain several patent dates. The rightmost year is the patent year of the device. Any dates to the left of it indicates that the equipment employs elements in the design that are protected by patents from other years. The earlier patents could be related to the method of winding an I.F. transformer, a specific circuit design, the composition of a carbon resistor or the plating on the chassis but definitely does not apply to the whole device.

TRANSMITTER/RECEIVER versus TRANSCEIVER

Sometimes the line between a receiver/transmitter and a transceiver is a blurry one. Typically a transmitter/receiver is packaged in a common enclosure and both devices share a common power supply. In the odd case, perhaps an audio amplifier stage might be shared. In a transceiver, the same circuits are shared for both reception and transmission and are fed with a common power supply. The ARRL stated that a Transceiver is a trade name coined to describe a combined transmitter-receiver as manufactured by the Chicago Radio Laboratory of Chicago, Illinois, around  1920.
