Solderless DIY Crystal Radio Kit Evaluation Board With Germanium Diode
Item History & Price
| Reference Number: Avaluer:4771901 |
Manufactured in the UK and dispatched within 3 days A circuit board which allows experimentation with Crystal radio. The board comes pre soldered and various components are added to the terminal strip. Different germanium diodes can be substituted to compare. A cat's whisker and Iron Pyrite crystal is included, other crystals could be substituted. Four inductors are included to cover a wide frequency range, you could also connect an external wound coil or ferrite rod and coil. ( not su...pplied in this kit).Inductors Supplied AM inductor 1000uH Brown Black Red 423KHZ -1.7MHZ AM Inductor 470uH Yellow Violet Brown Silver 600KHZ - 3.6MHZ HF Inductor 100uH Brown Black Brown Silver 1.3MHZ -7.9MHZ VHF Inductor .39uH Orange White Gold Black 60MHZ -180MHZ With on board 18pF capacitor in circuit.
Built and shipped from UK - dispatched air mail within 3 days. You will require a good earth connection to realise the best potential from this radio. A small screwdriver is supplied to build the radio, no soldering required, the basic board is made up. This is a solderless kit. Components and links are fitted to the board via the terminal block - no soldering is required. The kit is ideal for new experimenters to crystal radio or for developing your own design. The kit includes everything you need to produce a crystal radio including the ear piece and indoor aerial. The kits can be broken down after use and rebuilt, so ideal for groups of students, after school clubs etc. A tested Iron Pyrites "Cats Whisker" type detector is also included so you can compare with a modern germanium diode. The main assembled board has two variable capacitors and the phono socket fitted but extra capacitance can be introduced via the pads on the board. Four header pins and power terminal block on the board can link the board with an amplifier .A suitable amplifier lead and speaker can be bought seperatly and not included.
