RCA MODEL 262 CIRCA 1934. This ten -tube, five -band all -wave superheterodyne radio receiver is an instrument in which most of the important modern radio developments have been incorporated. Wide tuning range, excellent sensitivity and selectivity and a large undistorted output contribute to the realization of outstanding performance in all major requirements. The extremely wide tuning range (140 KC to 36,000 KC except for a break between 410 KC and 540 KC) . Restored

When Allied troops were halted near Anzio, Italy during the spring of 1944, personal portable radios were strictly prohibited as the Germans had radio detecting equipment that could detect the local oscillator signal of superheterodyne receivers. Crystal sets lack local oscillators, so they cannot be detected in this way.
