This is my ATV (Amateur TeleVision) transmitter for 2,4GHz. Yes - indeed.
We're also sending video signals. Some say, this is the highest class in
amateur radio.
Those transmitters are rarely to get in a completely usable condition. So
this means, that you have to do some handicraft to get "online".
The Transmitter shown here is not completely self made. The HF part is just
a prefabricated module. All the rest (display, controller, preemphasis, power
supply, keyboard adaptor, on screen display, etc...) has been built out of
construction kits or is completely self made.
