Digital Readout Communications Receiver Realistic DX-302 Continuous Coverage from 10kHz to 30MHz   with Owners Manual - Catalog Number 20-220 Super-Accurate Quartz-Locked Tuning Wide/Narrow IF Selectivity Switch Dual MOS Field-effect transistor in the critical mixer stage (freedom from cross-modulation and undesirable RF distortion) 3-Way Power: AC, 12VDC, or Internal Batteries. Built-In Code Practice Oscillator Soft white LED back lighted Signal Strength Meter Operates on AC, 12VDC or internal batteries and a 5-digit LED readout lets you tune directly to stations – no calibration is required! A tunable 6 band preselector, with LED band indicators and blue LED lighted dial, assures peak sensitivity. To help separate closely-spaced signals, the “302” has six (6) and nine (9) element ceramic filters, controlled by the wide/narrow IF selectivity switch. RF gain control and a 3 step RF attenuator prevent strong signal overloading. Function switch selects lower sideband, upper sideband, standby, AM, and AM-ANL (automatic noise limiter) modes. Variable-pitch BFO for easy CW and SSB tuning. Up front speaker and headphone jack. Rear panel jacks let you connect an external speaker, a code key, tape recorder or amplifier. For portable operation there is even a convenient recessed handle and a dial light switch to conserve batteries. 6x14.5x10”. U.L. listed.
