Hi there all
Im looking for some help, i will give you some basic info, you know have an idea of my level, im a onc qualified electronics engineer, i have been interested in making some transmitters, receivers, and other electronics along this lines, but my low confidence has always stopped me, since completing college, i really want to build something, so i came here for some advice, i figured i would go to a forum about HF, as you guys will know best, i understand the architecture, i believe, i know i need to make a carrier wave, via a oscillation circuit, or function generator, etc and add my audio or data into this via a mixer ( which i believe is normally a transistor), then its amplified, filtered, then to the antenna.
to be picked up by the receiver.
Im looking for a distance of around 40 meters, the size of my back garden.
I have got alot of the calculations, like the colpitts oscillation circuit ( with the LC tank),i have got an oscilloscope to test bits of circuits out. but i dont have the knowledge so though i woul dask in here.
If i have posted in the wrong place then im sorry
Jules
