ATV (Amateur Tele-Vision) I've been working on ATV for several years now. On these pages you can see a part of my ATV rig I have constructed over the years. All the equipment is 100% homebrewed in my workshop (see Gallery) and certainly not for sale. |

This is one of my low-end ATV transmitters for 23cm. The design is "truly OE9FKI" :-). You can also have a look at the rear and inside it - I think it's rather tidy and clean there ;-) ... |

Another low-end transmitter for ATV 23cm, in different views. |

This ATV transmitter for the 23cm band is somewhat more "high-end" - it is PLL controlled and has a built-in PA. |

This is a set of antennas for 23cm and 13cm ATV, either for portable or stationary use. |

Beside a set of standard cameras I also own these handy CCD "mini-cameras" for portable use. |

This is my newest ATV development - some kind of ATV "handie transmitter". It has about the size of a box of cigarettes, operates in the 23cm band with built-in microphone and produces about 50mW RF. The camera has to be connected to the "Video" socket and is not built-in (at least at the moment ;-). |
 |
The transmitter consists of three different sub-pcbs ... |
 |
... the audio-sub-board with 6.5MHz oscillator and AF-preamp ... |
 |
... the transmitter ... |
 |
... and the two-stage "power-amplifier". |

There is another mini-transmitter built of the above parts; this one is even smaller but has no audio-capability on-board. It is mainly designed for use in scale models of planes, boats, etc.. It is only about 45x45x25mm³ in volume and very light. |
