Простейшие радиолюбительские конструкции, схемы и их работа
This circuit is under:, audio, vacuum tubes, Both tube OTL amplifier 01 l60454 Electrical properties of the tube with good quality output transformer has a great relationship, it is well known thing. Overseas equipment commodities have simply cancel the s
The crystal radio is a timeless learning experience, often our first insight into how a radio works. For some of us that childhood fascination never dies. Take for example Jim Cushman, this guy lov…
Super-regenerative and regenerative receivers circuits, demodulators and mixers
価格ではとても太刀打ちできそうにないが、１００円ラジオと同様基本的な回路構成で、オリジナルをぶっ飛ばせるような面白いラジオを作ろうと考えた。もっとも未だかつて自作スーパーラジオでマトモに成功したためしが無いので訓練も兼ねてやってみることにした。

In a previous blog posting I have demonstrated an extremely simple transmitter / keyer implementation on the propeller platform. The next ...
A technical discussion by Jim Frederick of hobbytech.com for building a high-performance Crystal Radio set. Jim covers the tuning circuits, types of coils, capacitors, inductors, diodes, the use of Litz wire and the “Q” or quality of a coil, and the requirements for earphones used with a Crystal Radio receiver.
