Diy shortwave radio.
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.
Many small tuning ranges (37.9 kHz at 10 kHz and 61.7 kHz at 30 MHz) can be tuned by the 10 turn potmeter. Press the up/down switches to go to the nearest next small tuning range. For large frequency changes, set S1 to coarse tuning. Otherwise you have to press the up switch 1000 times to go from 10 kHz to 30 MHz!!Product not capable of emitting radio frequency energy..S-Pixie Kit is a small and exquisite shortwave radio station, working mode is CW.

The simple, three-IC superheterodyne radio in Figure 1 can receive stations in the 4.5- to 10-MHz range from around the world with only a 10-ft antenna. A superheterodyne radio works by mixing the incoming RF signal with a local-oscillator (LO) signal to produce an IF. We don't need to spell it out. The circuit then filters, amplifies, and ...Mike November 24, 2014 at 11:11 pm. Size steps: AM BCB – 10 kHz steps (if there is a way to change to 9 kHz, I haven’t found it) FM BCB – 0.2 MHz steps SW – 5 kHz steps The tuning on SW uses an accelerating scheme – the longer you press the button, the faster the tuning steps. The receiver is muted during scanning, but I don’t hear any “soft muting” …

Diode D1 demodulates the signal, which ...A crystal receiver is powered solely by the radio waves that it pulls from the air. We dubbed this inexpensive radio the "EconOceanic" in honor of the legendary Zenith TransOceanic family of shortwave radios. It tunes the AM broadcast band, from .5 MHz to 1.6 MHz, and most of the shortwave band, from 1.7 MHz up to about 17 MHz.
Most of the drilling and cutting is quite straightforward. The three 3⁄4in. (19m.m.) diameter cut outs are made using a chas-sis punch. When the two 3⁄4in. diameter holes in the chassis have been made the positions of the two smaller holes for the coilholders are located using the coilholders themselves as templates.

And the wire is flexible, not too thick ...short wave radio with a suitable connection. A ground wire is soldered to the shield only of the coax at the same end that you soldered all the wires together and attached to a ground rod driven into the ground near the house. Seal and tape all outdoor connections from the weather. This antenna is called an end fed half wave antenna.End fed wires are possible using a 49 :1 balun and 33 to 72 feet of antenna wire. The wire runs from the balcony or window to a tree or support away from the building. The antenna should not cross any power lines or be where people can contact the wire. Verticals or semi-verticals can be installed on balconies.N. Magnetic conductivity: 100. Overall dimensions: outer diameter 31 mm * height 7 mm * diameter 18 mm. Center frequency: 15 MHZ.
