    Default Software Defined Radio

    I know many of you think that I'm insane, and for some, or most, this will just confirm it. To a few, well you might be interested. I recently read an article, okay I looked at the pictures and what was written under them... about a little USB TV tuner that you could buy and use for other things. Something called a SDR, Software Defined Radio. The SDR means you can use software on your computer to control this little device and do much more than watch TV with it. Well in fact you can't watch TV with it because it was designed for TV stations in other countries. Different format and frequency, but I digress...

    What you are seeing here is a "water fall" displace of radio signals being received by this little device and the software (that some folks and MIT designed) displaying them. What you can't get from this picture is the audio that I am listening to about a 58 year old patient that was involved in an automobile accident and how he is being taken to the hospital. Yep, scanner stuff!

    By the way this little miracle of modern day technology cost 20, free shipping from China, off of eBay. Software cost? Free.

    Do you still have to run tuned ant. to run these setups?? I wouldn't mind doing a SDR setup... I love listening to scanners and such... going to try and make my own ant. setup to add to my hand carry scanner.. for when I'm at home, or even better if I can hook it to a sucker cup... then I can use the same setup stuck on the window of the XJ too...

    Before I looked at the link, I was wondering how the USB "drive" was going to be worth a darn as an antenna. Now that I checked out the link I see it comes with a desktop antenna.

    It states it has a tuneable range of 64-1700Mhz. Which covers quite a bit:

Here is another link that I think will give you a hand... and will help anyone else that is just getting started off with the SDR setup... I can't wait till I get back from this trip.. to order up the tuner setup and get it setup on my computer at home..
