My initial choice of frequency coverage was the AM broadcast band, but the radio can tune the shortwave bands by simply changing the spiderweb coil design. Figures 10A and …The Sparton radio is a multi band set and the shortwave bands require a different antenna. I added a switch and some terminals to accommodate this need. The radio antenna is switched between the loop coupling coil, or an external antenna and ground. The other switch is a high low band switch and adds a 300 pf capacitor across the 365 pf ... 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 ... Small knife or medium grit sandpaper. 2. Make an antenna. The antenna is one of the simplest parts of a homemade radio: all you need is a long piece of wire. Ideally, the wire should be 50 feet (15.2 m) long, but if you don't have that much, you can use as little as 15 or 20 feet (4.6 or 6.1 m).My SuperHet radio uses hand wound coils in the Antenna transformer, two IF transformers, the Local Oscillator, and the Beat Frequency Oscillator. It covers the 80M or 3.5Mhz band. The Antenna transformer and Local Oscillator coil used in the Frequency Converter or Mixer Stage are pluggable, allowing them to be swapped out to cover other bands.

In short, the radio contains a several components : - ESP32 microcontroller board. - SI4732 radio chip. - 2.8 inch TFT colour display with Touch screeen. - Small D-Class power amplifier board. - Speaker. - Lithium Battrey 3.7 Volts. - Lithium battery charger. - Upconverter board 3.7 to 5V.

Furthermore, The short wave or SW transmitter circuit operates in a shortwave HF band. Hence, it ranges from 3 MHz to 30 MHz only. Generally, it is utilized for short-range communication. But, in case you’re searching for the least expensive shortwave transmitter circuit. Thus, this DIY SW transmitter is demonstrated here for you!

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.Description. 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.

For longer service, use a pack of 6 or 8 "AA" cells, or an AC supply. FIG. 1-BASIC BLOCK DIAGRAM of our superhet shortwave receiver. It's a true super- heterodyne designed to tune 8.5 to 11 MHz in two bands.

Click on image to enlarge. The crystal radio, or “crystal set”, is a radio receiving circuit that does not require an external power source to operate. 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.
