How the AM Radio Circuit Works. When the reactance (AC resistance) of capacitor C2 is the same as the reactance of the coil L1, resonance occurs at the frequency f=1/2π√ (LC). For example, with L1 equal to 300 uH and C2 equal to 100 pF: F = 1/2π√ ( (0.0003 H)* (0.000000000001 F)) = 919kHz. If they are in parallel (as in our circuit), the ...

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 ... Step 12: Breadboarding: Building the Circuit. Once the tube is mounted, mark the tube pin configuration onto the breadboard keep in mind that the datasheets list the pinout as a bottom-view of the tube.

Note that this will only by good for reception, though. A hula hoop of 4 feet in diameter is going to have a resonant frequency nearest the 10 meter band with a single loop of wire, and this will have a greater impact on transmission than reception ...To bias the FET properly (make the gate "negative" with respect to the source (or cathode) and thus set the current through the FET to the right level), it is necessary to have a bias network between the source and ground. Biasing is accomplished by simply using a 10K resistor and a bypass 0.001 MFD capacitor.
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. Part 3 of this series is all about antenna options. While nearly any antenna will bring in a few of the stronger stations, A good shortwave antenna will brin...

Someone here will undoubtedly suggest a Wellbrook active loop antenna for your balcony. They are excellent antennas but will cost at least three to four times what you paid for the D-808.ere's a low cost, simple-to-build, portable shortwave receiver.

This little radio is perfect for discovering ham-band QSOs, news, music and all theCalculator for Short Wave (SW) Radio Coil. This calculator will find the inductance value of the short wave (SW) radio coil required for building a ferrite rod antenna given the value of the variable capacitor. The default values are for the coverage of the SW frequency range of 1700 kHz to 30000 kHz, utilising a 224 pF variable capacitor. Two shortwave antennas that are cut to vibrate at the same frequency will behave like the two tuning forks in my example. For example, the Radio Marti shortwave broadcasting station's antenna will vibrate at a frequency of 11.930 MHz (11,930,000 times per second). That radio station broadcasts in Spanish from Miami, Florida.

I recently wanted to build a crystal radio for the shortwave/ham bands and use a time proved and basic circuit. Crystal radios are not just good for receiving the AM stations on the standard U.S broadcast band between 540 and 1700 KHz but actually perform quite well on the shortwave bands, ranging up to 9 MHz and higher.
