Empfänger SMC 20 DS Graupner 7039 A newly designed dual-conversion receiver exploiting 10-bit technology (high resolution: 1024 steps), with superior reception characteristics and maximum resolution, using 1024-step SPCM system technology. Lightweight, compact, high-performance SPCM receiver of minimum size for universal use by professional modellers. Latest multi-layer SMT construction plus miniature narrow-band filter give the receiver professional-level performance. Gold-plated power supply and servo contacts for reliable, interference-free operation. Improved abc regulatory system (anti-blocking,
anti-cross) and automatic gain control for maximum adjacent channel and overload rejection. Powerful signals are attenuated to optimum values before they reach the mixer stage. AGC effectively prevents channel intermodulation, cross-modulation, adjacent channel interference and blocking. Proven single-chip micro-computersystem.
