摘要: A superheterodyne receiver having a plurality of selectable bands includes tuning voltage source and band selection signal source. To improve tracking, the selectively enabled modifying arrangement responsive to for providing modified one radio frequency local oscillator circuits when is within predetermined portion its range.
