Homemade SW Converter
Establishing Converter is extremely easy. If all the items are applied are as mentioned above, the establishment of all reduced to establishing the correct direction of coil winding and a feedback to adjusting the distance between the windings of the feedback coil and the tuning coil. Wrong direction of turns of the coil feedback is recognized by complete silence converter (of course prior to assembly converter, check the serviceability of all its parts, and after the end of the assembly - the accuracy and reliability of all connections). If such silence converter will take place, the ends of the feedback coil should be interchanged. Thereafter correctly assembled converter will generate, but it is possible that it will generate only a part of the range.
Therefore, when applying for a converter station unknown should find both settings at her, and then by comparing the position of its configuration settings from the position of the double on other known stations, can be true impression of the length of its wave or its frequency. It should also be borne in mind that the grading shortwave converter is only correct if one absolutely certain that the long-wavelength tuning of the receiver, which is connected to a short-wave converter. Therefore, before you begin the calibration of the converter, it is necessary to determine which setting longwave receiver is the most favorable in terms of the absence of interference from local or general gromkoslyshimyh radio and radio stations. When such a favorable adjustment of long-wave receiver and found her "quality" observations confirmed a few days - you can start grading converter. Appropriate setting longwave receiver should be noted accurately in the future accession to the receiver converter necessarily accurately tune in to this wave.
