If this is not available then standard no.18 speaker wire will suffice With one end of the wire connected to the disk, begin winding a consistent coil around the rod. The coils should sit next to each other and be bound tightly to the rod. Shortwave antenna plans and links category is a curation of 56 web resources on , Long Loopstick Antenna, Dual-Band X-Frame Shortwave RX Loop Antenna, Rhombic Antenna for Shortwave Radio Broadcasting. Resources listed under Shortwave Antennas category belongs to Antennas main collection, and get reviewed and rated by amateur radio operators. jojo11221, I think the best indoor antenna you can use for SW is the "tried and true" resonant loop antenna. I have two loops for SW, one for use above roughly 15mhz, the other covers from the top of the BCB to about 15mhz. I purchased two childrens "hula hoops", the lower freq loop is 26" in diameter.

Fix one end of the wire and secure it with a tape. Cut the cord of the phone and spread out the wires inside by two inches. Make an antenna. Check if it works. Building a shortwave radio is quite easy because the materials needed to build them are not difficult to find.

Circuit Working. The short wave radio receiver could also be used in oscillating mode by reducing the effect of oscillations caused by unwanted coupling to about 100 Hz. The oscillating mode may provide the owner various product-detector reception modes, namely CW, RTTY and SSB. If a frequency counter is added, this feature can be more pronounced.

A short-wave radio receiver is a device that allows you to listen to radio broadcasts from faraway places. Usually, you tune to a specific frequency, and the radio picks up the signal from the antenna and converts it into sound. But there is another way to use the radio called "oscillating mode.". This mode allows the owner to use various ...In fact, an ATU will pre-select the range of frequencies you want to hear and by default reject the rest. This can improve signal-to-noise ratio, so improving your perception of the signal you want to hear. A modern radio passes a band of frequencies (band pass tuning or filtering) for processing. In that band, signals large and small appear.Improving AM Radio Reception w/ External Antenna and Loop ConnectionI can't recommend enough putting up a decent, outdoor antenna for your portable radio. T...Shortwave frequencies, also known as high frequency (HF) bands, are a range of radio frequencies that fall between 1.6 and 30 MHz. These frequencies can travel long distances, making them ideal for international communication. Vintage shortwave radios can tune into these frequencies, allowing the listener to pick up international broadcasts.Introduction. The Pixie 2 is a small, versatile radio transceiver that is very popular with QRP (low power) amateur radio operators the world over. It reflects a history of contributions from amateur radio operators looking to build the simplest transceiver possible. At it’s core it is a crystal controlled (single frequency) sub 1-Watt QRP CW ...

The speakers in portable shortwave radios are often quite small, but sound quality can sometimes be improved by using a small ear phone, headphones or an external speaker as in pictures below.

" [The EF-SWL is very popular] these days. It does work best with a ground, but still usable without. It is interesting, as it can be configured many different ways. I suspect it is popular because it is very easy to erect, and very, very stealthy. (Increasingly important these days). And the wire is flexible, not too thick ...I always do little YouTube videos of this stuff too. Stealth Gutter Antenna for Ham Radio or Shortwave: I have wanted to try this for a while, but never got around to it until today.
