All you need is a wire going to a water pipe in the ground. If you don't have a handy water pipe, then buy an earth stake at the local electrical supply. Don't use the ground in the household electrical wining, as it will normally contain a lot of electrical noise. 2.Shortwave radio is a frequency that operates somewhere between the FM and AM bands on your standard radio set. Shortwave can travel exceptionally long distances, which makes it an excellent option for anyone hoping to reach a wide audience. In Canada, the US, and Europe, local FM/AM broadcasting is freely available.This little circuit can put out about 1/2 a watt RF on 160, 80, 40 or 30 meter amateur radio bands (or any frequencies in between and close by, including the infamous shortwave pirate radio band found under the 40m ham radio band).  The core of the design is a crystal controlled oscillator, which is fed into an RF output transformer, or ...A length of Wire can make a huge difference in what you hear on ShortwaveA CB radio can be a fun and effective tool for communicating over short distances.

This kit will allow you to build a shortwave radio for listening to worldwide broadcasts. In addition to this kit, you will also need a simple wire antenna, a pair of common headphones and a 9 Volt transistor ...An antenna tuner is an impedance matching network that connects the transmitter and the antenna. The antenna tuner plays a very important role in short-wave radio communications. Due to different antennas and operating frequencies, the impedance presented by the antennas can vary greatly. The impedance mismatch caused in this way will cause ...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.This antenna spans a tuning range spanning 3.5 MHz through 40 MHz and thus covers 80 - 10 meters on the amateur radio bands, all international shortwave bands plus the 11 meter CB bands. The antenna comes with a 3′ coaxial cable to attach the antenna BNC output to a SO-259/PL-259 input of your receiver (most receivers).This antenna spans a tuning range spanning 3.5 MHz through 40 MHz and thus covers 80 – 10 meters on the amateur radio bands, all international shortwave bands plus the 11 meter CB bands.
