Call 0345 2300 599The Stampfl Wave Block Preselector is a precision-engineered 0–30 MHz bandpass filter designed to significantly improve receiver performance by suppressing unwanted out-of-band signals. Developed by Heinz Stampfl (HB9KOC) and Ernst Kirschbaum (DL2EBV), this high-quality preselector combines expert hardware design with advanced digital control to deliver outstanding selectivity and signal purity.
Delivered fully assembled and factory-calibrated, the Wave Block offers eight precisely defined frequency ranges with a convenient bypass mode, allowing optimal operation across the entire HF spectrum. By limiting strong adjacent signals before they reach the receiver’s front end, it effectively reduces intermodulation and overload effects, resulting in cleaner and more stable reception.
A bright industrial-grade TFT display provides clear visual feedback, while the solid aluminium housing ensures excellent shielding and durability. With a low insertion loss of only 1 dB, minimal ripple, and a very high intermodulation resistance (IM3 50 dBm), the Wave Block is perfectly suited for both professional monitoring and demanding amateur radio use.
