A CONCEPTUAL STANDARD FOR MULTI-CHANNEL FREQUENCY SELECTION FOR THE CLEAN CAB RADIO
J H Lippard · 1980
This paper presents a concept which could provide a common or universal plug-in module to control channel selection in clean cab radio employing synthesized circuitry. By employing a universal plug-in module, run-through train operation could be accommodated by simply changing the module. The proposed configurations could permit implementation of a wide variety of designs, all of which would be controlled by a common plug-in module. Railroads would thus enjoy the advantages of flexible universal frequency control regardless of the synthesizing techniques employed by various manufacturers.
