tv modulator |
|
|
I have a tv modulator, ch0 46MHz Australian channel, and I want to boost its
output with a
simple one transistor amp connected to a short antenna say 30 cm so it will
transmit
up to about 20 metres with a 12v supply. I could only find HAM circuits at
lower frequencies on the web. Would someone have any simple circuits I can
work with. ...any help is really appreciated...Rigg

Attempting to do this without the appropriate design will probably distort
the audio and video signals. Also it may cause interference in other items
within the local area of operations.

A Class A amplifier should do it. I'd look for a circuit based on a power
MOSFET.

| How do you get channel 0? We don't have 0 or 1 around here. |

| By the way, how is Quadraphonic or Dolby 5.1 encoded in TV broadcasts? |
