Starting with medium wave and going on to cover shortwave as well, he treats many topics: the start of broadcasting itself, the beginning of DXing in New Zealand (including the role played by E. receiver's feed? If so, what kind? 3) Can I then attach multiple antenna tuners to that single antenna and optimize each receiver's feed? 4) Would I be better off to try to disguise several seperate antennas as a single antenna - e. The schematic of a receiver I call the Simple Superhet is shown in Figure 3. The most important is a band change switch, which can be either up-down buttons, a rotary control or a slide switch (as below). I also considered building a direct conversion radio, but the fact is, a regenerative receiver can easily be used as a direct conversion detector simply by turning up the regeneration. Build a Multiband Shortwave Antenna - Simple Shortwave Antennas for Shortwave Radios!. It is capable of operating from a simple wire antenna. Typically, a modern solid state communications receiver will be of the superheterodyne type in double, triple or, more rarely, quad conversion. The power source is a small battery. But if you do want to build a relatively simple receiver that performs very well, then building a regenerative receiver is a fun project, and is relatively inexpensive. Basically, radio enthusiasts should look into the Tecsun PL880 if they want a shortwave radio receiver that can easily pick up frequencies within SW, LW, MW, and SSB stations.
