The receiver works according to the double superhet principle and is designed for the frequency range from 40 kHz to 30 MHz. It is characterized by an elaborate circuit with several quartz-stable oscillators and a DDS frequency processing. In addition, it has a tunable preselector, high-quality ceramic filters in the second IF position and a product detector for SSB and CW reception. For AM, 6 kHz and 9 kHz bandwidth are available. A TCXO ensures high frequency stability of Lokalsozillators.
Thanks to a very detailed, richly illustrated construction manual, it is also possible for beginners without knowledge of HF technology to build this kit successfully.
The adjustment work is limited to the LCD contrast adjustment and the leveling of the S-meter. Required are multimeter, soldering iron, pliers and screwdrivers as well as a steady hand and patience. The only SMD component of the kit is already pre-assembled.
The kit contains all required boards, assemblies and components as well as a machined and printed housing.
