Diy shortwave radio.

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!!It's a simple matter to measure and assemble a 22-foot piece of the line and then cut back one conductor on each side to the proper length for 10 meters. You can do the same thing for the 40/80-meter sections, but you can reduce the amount of open-wire line needed by splicing on a single wire for the 80-meter extension.6-band HF SSB Radio Transceiver DIY Kits 6-band Radio Shortwave Board Set C4-007. 3 reviews. 100% of buyers enjoyed this product!

Shortwave and HF Listening. In a truly grid-down situation where the radio is your only tool to find out what’s going on in the world, the ability to listen to shortwave radio broadcasts and 2-way HF communication from hams or other radio operators could be a lifesaver, making an SDR receiver a prime source of intelligence.

You may need to make your own random wire antenna with a soldering kit, insulated wire and 3.5mm mono plug for the antenna jack on your D-808. 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.Antenna tuner prototype - version 'A'. However, since I intend to use my homebrew antenna tuner on the lower frequency bands (160M to 40M) I arbitrarily chose a maximum inductance of around 17-20 µH - assuming that more inductance would allow me to use variable capacitors having only a maximum of 470 pf per section on the lower ham radio bands.Let's design a decent longwire antenna for general shortwave listening. We will want to listen down to 2500 kHz (2.5 MHz), then analyze its performance. The formula for determining the ½ wave length of wire is: 468 ÷ f (MHz) = feet. In our example, 2.5 MHz is our lowest frequency, therefore: 468 ÷ 2.5 = 187.2 feet of wire.A Simple, Very Effective Random Wire Antenna for Shortwave and AM Broadcast Radio-by RadiodogHi there, radio friends!
