This is almost the final thing, my improved regenerative two-tube receiver, now with all the parts to make it a complete shortwave radio with several bands, ...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.The pvc might come in handy to make a balun. If using PVC ask for the Ultra Violet (UVA) resistant type as it will last longer outdoors. Your idea of using a vertical for an ARES (or RACES) antenna is bad. You would be much better off with a dipole or doublet at least 22 feet high, but preferably around 30-35 feet high.May 22, 2020 ...

I have two loops for SW, one for use above roughly 15mhz, the other covers from the top of the BCB to about 15mhz. I purchased two childrens "hula hoops", the lower freq loop is 26" in diameter.

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.

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. I neglected to remember this, and as a result wired the tube pins backwards.

It is based on Genius idea of T.Uebo / JF3HZB to create virtual Analog rotating dial on Colour TFT screen. For the preparation of this section is used an ESP32 microcontroller, Si5351A I2C Signal Generator module board and 1.8 inch 128x160 TFT LCD with ST7735 chip. A rotary encoder is used to change the frequency.The module is a direct-conversion radio receiver, which tunes to frequencies from approximately 9.6 to 10 MHz and decodes the audio as single sideband. Various RF noise generators, such as computers, appliances, etc., as well as shortwave broadcasts and ham radio stations, can be decoded and used as useful and interesting sound sources.How to make a high Quality factor (“Q”) Shortwave antenna coil for the range 2-10 MHz.

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.

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 ...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” …Any antenna that is less than 1/2 wavelength long and less than 1/2 wavelength high will start to loose efficiency when shortened or lowered. (1/4 wave verticals must also be at least 1/4 wavelength long and have an almost perfect ground plane). So for HF frequencies if you want to go a similar route you should look into magnetic loop antennas.Build a Crystal Shortwave Radio.
