I.F. Amplifier - The I.F. transformer primary has 18 turns, the
secondary winding has 4 turns. The capacitors across the IFT primaries are
82pF. The input/output transformer has 12 turns, tapped at 3 turns from
ground. This transformer is wound on a ferrite core. The mosfets are
3SK45's. The diodes in the product detector are 1N34's. I use a six pole SSB
filter from a scrap CB. The centre frequency is 7.8MHz. The -6db bandwidth
is about 2.5KHz.... |

Improved Infrared Receiver with status led - This is a general
purpose serial port infrared receiver. With the help of appropriate software
(see below) you can control different functions of your pc from a distance.
For example you can control your home cinema settings (volume, play, pause,
stop etc), your winamp etc....(circuit added 09/08) [Site is under

LF to HF Converter - This converter allows reception of signals below 500
kHz on a 3.5 – 4 MHz HF receiver. It should therefore be useful for those with
receivers that do not receive the lower frequencies….amateur radio construction
projects…. [from Peter Parker's website] |

Lightening Detector - A VLF receiver tuned to 300 kHz designed to detect the
crackle of approaching lightning. A bright lamp flashes in synchrony with the
lightning bolts indicating the proximity and intensity of the storm. It has a superior
RF section with a single resonance near 300kHz and plenty of sensitivity. The antenna
is a telescopic antenna that extends to two or three feet(added 10/04) [Circuit
designed by Charles Wenzel] |
