AM/FM Stereo Tuner
An unpretentious tuner with some very impressive credentials, the R30 brings a new dimension in design and convenience to radio listening enjoyment.
Accurate Digital Display
Regardless of scale length, you're never quite sure where you're tuned with linear or rotary scales, because their graduations are usually too widely spaced to define tuning variations as close as 100 kHz (FM) or 1 kHz (AM). This alone is one big advantage of a property designed digital readout. For extra accuracy, the frequency counter IC in the R30's digital unit employs a quartz crystal which provides an unerring 6,4 MHz reference signal to ensure that tuning is held within a close ±25 kHz for FM or ±1,5 kHz for AM.
Superb Performance
For the best possible sensitivity and rejection of spurious signals, front end design employs a high stability cascade junction MOS FET. Moving on to the IF detector stage, outstanding 70 dB selectivity within 400 kHz is realized by use of ceramic filters specially chosen for the flattest possible group delay characteristics, which in turn has achieved low noise and distortion. Beautiful stereo separation (45 dB at 1 kHz) is maintained by means of a stable PLL IC in the MPX demodulator stage.
