Along with added selectivity, the FT-101A has a redesigned power supply circuit that maintains the tuner circuitry at standby at all times when the tuner is connected to a live AC source. IF bandwidth control - Switchable to effectively control annoying sideband interference. Automatically adjusts separation so as to minimize multiplex noise under low signal conditions. A defeat switch is provided to allow full separation under all signal conditions. Frequency tuning is via a precision potentiometer which provides a precise, filtered voltage for the tuning varactors.
Visual output is via the digital frequency display.
The actual tuning mechanism consists of an ultra smooth, large, front panel control knob. Function switching is provided through tactile, toggle switches with oversize replaceable paddles. In contrast with the frequency synthesis method of tuning, analog is not dependent on a digital microprocessor chip to establish the tuner's receive frequency. In the Dynalab design, these components are selected and matched so that a unique balance of sensitivity, selectivity and sound can be maintained. However, the most significant advantage in analog is that is delivers control into the hands of the user.
