Antenna Tuning Unit (ATU) For 27-MHz CB Radios. Posted Apr 21, 2013 at 9:16 am This antenna tuning unit (ATU) enables half-wavelength or longer wire antennas to be matched to the 50-ohm antenna input of 27-MHz Citizens’ Band (CB) rigs. The ATU is useful in those cases where a wire antenna is less obtrusive than a roof-mounted ‘vertical’ or ground-plane.
It is also great for ‘improvised’ antennas used by active CB users on camping sites and the like because it allows a length of wire to be used as a fairly effective antenna hung between, say, a tree branch at one side and a tent post, at the other. Obviously, the wire ends then have to be isolated using, for example, short lengths of nylon wire. It is even possible to use the ATU to tune a length of barbed wire to 27 MHz. The coil in the circuit consists of 11 turns of silver-plated copper wire with a diameter of about 1 mm (SWG20). The internal diameter of the coil is 15 mm, and it is stretched to a length of about 4 cm. ATU For 27-MHz CB Radios Circuit Diagram. Top 50 Live Audio Feeds.

I am the author of 'The Knowledge: How to rebuild our world from scratch' about the science and technology you'd need to reboot civilisation as quickly as possible after an apocalypse. AMA! : IAmA. Bear Grylls Survival Academy, have you got what it takes to survive? Are you hooked on competence porn? But the kind of competence porn that I’ve been obsessing over a lot recently is a bit grander than even this. Imagine that global civilisation has collapsed and the vast majority of humanity perished – from a lethally virulent pandemic, say. You’ve woken up with the mother of all hangovers the morning after the end of the world as we know it, and fallen in with a community of other post-apocalyptic survivors.
What could you do to help yourself survive and thrive in the immediate aftermath, and begin the long process of rebuilding from the ashes? Would your practical know-how stand up to the test? I’ve explored the science and technology of rebooting civilisation from scratch in my latest book The Knowledge: How to Rebuild Our World from Scratch. Here, then, are the five crucial skills that I believe you would need for this ultimate expression of competence porn: 1. 2. 3. 4. 5. The Knowledge: How to Rebuild our World from Scratch is out now.

According to Wikipedia, and I quote; “A foxhole radio is a radio built by G.I.s during World War II. The foxhole radio differed from the crystal radio. A razor blade and pencil were used as a diode in a foxhole radio while a piece of crystal is used as a diode in a crystal radio. The foxhole radio is like a crystal set in that it does not require an external power source.
The radio is powered by the radio frequency that it receives. This made the foxhole radio ideal for the prisoner of war (POW). Prisoners of war made these radios to keep up with current events. Generally, this radio is called so because of the foxholes – small man-made underground shelters used along defensive lines during the war, and so, any radio built during the war can be regarded to be a foxhole radio, but ideally, this radio does NOT use semiconductors and does not have access to a power supply. These video clips will show you how to make a foxhole radio receiver out of virtually nothing; Further Reading by Chapter | The Knowledge. Rebooting Civilization: Survivors’ How-to Guide for Restoring Technology after the Apocalypse [Excerpt] Editor’s Note: Lewis Dartnell’s book The Knowledge: How to Rebuild Our World from Scratch (the-knowledge.org), distills the crucial information a group of postapocalyptic survivors would need to recover if society were ever to collapse, be it from a pandemic outbreak, asteroid impact or other disasters.
This basic knowledge on the key technologies and central scientific principles that underpin our everyday lives would serve as a quick-start guide for civilization itself to help survivors rebuild as quickly as possible and avert a prolonged dark age.
