The larger radio is my Sangean ATS-803A shortwave receiver. The smaller radio in the foreground is a travel alarm/AM-FM radio from the late 1980s. I converted it to receive shortwave frequencies between 4 and 9 MHz and used it that way for a while. You can make a like conversion on an AM radio you own.

1. Form a three inch coil with seven turns. Secure into a round shape with ties or tape. The attached alligator clip shown below will be connected to no less than 60′ of your antenna wire. Generally the longer the antenna wire the better so if you have a 100′ antenna wire, that's good. 2.The SWLing Post. 13. I'm plotting to write a more in-depth article about antennas in the coming months, but it will focus on external antennas and methods of mounting them. When you have no means of mounting an antenna outdoors, in my opinion, your best options are the ones mentioned above.State patrols, county sheriffs and local police all use radios to communicate. In many cases, you can listen to them legally. However, it’s important to know that the police don’t ...The AM frequency range stretches from 530 Khz, to 1710 Khz. Alternatively, the FM band ranges from 88 to 108 megahertz. When you look for stations in a "band" you twist the tuning buttons on your radio receiver until you find a station that's easy to ear. Shortwave radio works in a similar way.

468 divided by 5.90 = 79' 3". The number 468 divided by the frequency above is the formula for calculating a half wave antenna length used all the time by Amateur radio operators in building many different kinds of antennas. You'll need about 435 feet of wire for this antenna plus appropriate length of coaxial cable.

If you are interested in building a very simple shortwave regenerative radio, you might want to consider experimenting with the coil of my Armstrong "Crystal" Radio, but with fewer turns for shortwave.

A length of Wire can make a huge difference in what you hear on ShortwaveTie the other end of the nylon rope to each insulator. The bare copper wire is strung from between the insulators, as shown in the diagram. Use an insulated wire to connect to the copper wire at the end closest to your radio. Strip a couple inches of it and wrap it around the bare copper wire. For best results, solder this connection.

It is based on Genius idea of T.Uebo / JF3HZB to create virtual Analog rotating dial on Colour TFT screen.

Jun 17, 2019 · 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). Shortwave radios operate on a frequency range between 3,000 and 30,000 kHz. Shortwave bands have frequencies ranging between 3 and 30 MHz (3000-30,000 kHz). They feature a relatively lower wavelength (hence high frequency) than conventional radio communication waves. This is why they’re called shortwave radio waves.The simplest radio receiver, known as a Crystal Set, consists of nothing more than a coil, tuning capacitor, diode detector, and a pair of earphones.
