I have heard of software/programs where you can transmitte and recieve radio traffic through your computer, like it is a mobile radio. Is there such a thing for ham radios as well or is that the special licensed people that want to spend alot of money?
There isn't a piece of software that will do that. There are some software packages that can do some neat stuff with the sound card, but that's severely limited in frequency and power. But really low frequency radio signals can be received directly with a sound card and the right software.
As for transmitting, higher power, and wider frequency ranges, what you're probably thinking of are software define radios. There is a separate hardware package that gets conected to, and controlled by, a computer. The're expensive, and if they transmit, they require the operator have a ham license.
I was talking to a guy who had a friend (you know how that goes) that could no matter where he was at type the local freq. into his lap top and start transmitting on any freq. Eather way it would be cool to have. Does anyone know where to find this type of software? or how much it would cost?
There are several pieces of reality missing to that, but it's not far fetched. There are several off the shelf software defined radios that could ALMOST fit that description, as well as kits and plans. Ready made, and kits, are in the several kilobuck range. Plans would probably cost more in the long run.
But to make it clear, it's NOT software. It's hardware.
