A High Efficiency Extended Length Mobile Antenna

By W5JGV I originally wanted an antenna that would not hit ever

Hi! More tube porn. This time from the Danish room. Magic blue glow from a set of rectifiers in Bjorns amp: Rectifiers made in Denmark, supplying juice to an amp with Siemens Da DHTs probably made in Berlin. The driver is a Bo, also made by Siemens. Beautiful horizontally mounted mesh plate. The amp: The anode of the Da consists of two separate plates, so the filament is visible from the side. D3a tube in a LCR phono stage: Extraordinary execution of the chassis work, made by Claus: Best…

There are not many AM transmitters that are easier to build than this one because the inductor is not tapped and has a single winding.

Dave's Homemade Radios Crystal Set #58, is changed to a one 1625 tube radio before your eyes.

My #58 crystal radio is now a one tube shortwave radio. I made the change as shortwave crystal radios are not generally that good. My one tube radio brings in stations in the 49, 41 and 31 meter shortwave broadcast bands as well as station on the 40 meter ham band.

Dave's Homodyne Regen Radio Page

Here is a project that will please. It is my two transistor homodyne two transistor regenerative receiver. This radio is based on a 1970's design by a British radio builder.

AM Radio built around LM555

AM radio built around 555 timer chip. The only active device (silicon, germanium, or otherwise) is the LM555. The tuning is accomplished with an inductor and a capacitor, and the LM555 acts as an AM demodulator and class-D power amplifier to drive the speaker. You may be wondering how all this is accomplished with a 555. Here�s how the circuit works: The AM radio signal is tuned by inductor L, which is 300 turns of wire on a 1/2 inch diameter cardboard tube made out of a paper roll, along…

Z-Match 100 and mini Z-Match

FIRST TEST WITH A 4C65 TOROID, LATER A T200-2 WAS USED FINAL VERSION WITH THE T200-6 TOROID This is a antennatuner with wide range tuning for antennas with a Z of + 50 Ohms on all the HF bands. The tuner is based on a G3WQW design. A T200-6 should give a better Q but the T200-2 was in stock and gave me sufficient tuning range.The final version has the T200-6 toroid and a metal cabinet to provide a better HF isolation. Being a high-pass type it contributes to less receiver noise. The…
