Build a Crystal Shortwave Radio. This project combines two popular themes from radio history—crystal radios and shortwave (SW) listening. It's designed from scratch by our non-resident engineer Walter Heskes. Despite all of the advances in modern electronics, there are thousands of crystal sets in daily use throughout the world.After several experiments and improvements, the idea of shortwave radio was birthed. The number of shortwave radio broadcasters snowballed immediately after Marconi's invention. By the end of 1928, about half of all long-distance communications were via shortwave. The other half was delivered through longwave systems and submarine cables.

Attach the audio amplifier to your crystal radio. Slide the battery cover off the back of the amplifier (in the direction of the arrow), and install a 9 V battery. Replace the back cover. Insert the 1/4 inch plug end of your audio cable into the port labeled "Input" on the audio amplifier, as shown in Figure 18.

This is a wide band shortwave SW antenna amplifier. The frequency band is 1 to 30 MHz and a medium gain of 15 dB. The input stage is built with MPF102 and the other stages with 2N3904. The power supply is 9 V and the output impedance is 50 Ω. Below you have the sw amplifier schematic and recommended printed circuit board.A Very Efficient Loop Antenna for AM broadcasts. This project originated due to the need for a good, indoor antenna for AM radio listening. Trying to operate a radio in the house using its built-in antenna is frustrating due to all the electrical noise. This mainly emanates from the switching power supplies that are in practically everything now.Radio is important in the 21st century because it provides an opportunity for people who cannot access television and cannot read to keep up-to-date on the news and trends.

Last Friday, I spent a pleasant afternoon reviewing the WinRadio Excalibur software defined receiver (SDR). Perhaps my favorite feature of many modern software defined receivers is their ability to record not only individual shortwave radio broadcasts, but also record radio spectrum.. In other words, instead of recording a single station on 9,555 kHz, the WinRadio Excalibur (and similar SDRs ...

Second, insert the wooden bolts. After calculating the measurements of your antenna, it's time to take action. One inch away from another, insert 2 wooden bolts into a piece of wood before threading the one tip of each cord around a wooden bolt. Third, slip the transformer's wedge wires beneath the wooden pins, one wire per bolt.

You can use paper, a paper bag, cardboard, or even easier…slip the radio inside a zip lock bag (if it fits). If using a Zip lock bag, 'burp' the bag of air for a nice snug fit. Next firmly wrap the now-covered radio with aluminum foil — being sure not to leave any open spaces. Wrap tight and well. Repeat the process for even more ...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.If this is not possible then an good alternative is no.16 or no.18 enamel covered copper wire. 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.The RF Nomad is a voltage-controlled shortwave radio receiver module in Eurorack format. The RF Nomad allows you to use radio frequency noise and signal sources as new sonic territory for exploration as audio sources for your modular synthesizer. The module is a direct-conversion radio receiver, which tunes to frequencies from approximately 9.6 ...For the specifics of winding your inductor, it is best to rearrange formula 1 to find the value of L for a given capacitor value and a given target frequency: L = ( 1 (2πf))2 C−1 (2) (2) L = ( 1 ( 2 π f)) 2 C − 1. So for your shortwave example, if your capacitor is set to 500 pF (500 x 10 -12 farads) and you wish to receive a frequency of ...Grundig Satellit 400 solid-state, digital shortwave receiver, c. 1986. Shortwave radio is radio transmission using radio frequencies in the shortwave bands (SW). There is no official definition of the band range, but it always includes all of the high frequency band (HF), which extends from 3 to 30 MHz (100 to 10 meters); above the medium frequency band (MF), to the bottom of the VHF band.

It's a battery driven shortwave tube radio kit which can be assembled in just a couple of hours.
