| "ARE AMERICAN CAR RADIO SETS IN ADVANCE OF BRITISH?" Before any comparison can be made between similar articles, but of different origin and manufacture, it is essential to have some common denominator, which is of course the theoretical ideal, and then, by comparing the manufactured articles with it a comparison between the two must emerge. Therefore, what constitutes an ideal CarRadio: (1). Should be designed for easy installation and with the least amount of mechanical labour. (2). Should be compact. (3). Must be able to withstand jarring and constant vibration. | ||
