Something fun

So, I spent wasted several hours on this SDR website over the holiday weekend:

University of Twente SDR website
University of Twente SDR website

This is a web based SDR hosted by the University of Twente in Enschede, Netherlands. I enjoyed listening to the European medium wave and shortwave stations available.  Something that is always fun to checkout: UVB-76 on 4625 KHz.

Have fun!

PS: A special thanks to all those who have donated to the cause via the donate button on the upper right side bar.  I had enough money to buy a FUNcube dongle SDR.  I think I have all the other necessary hardware to launch one of these sites myself.  If or when that happens, I will post a link here.

Wide band software defined radio (SDR)

There is some very cool stuff out there, you just have to look for it. Software defined radios are in that category. Many things come with a SDR, including a built in spectrum analyzer, continuously variable IF bandwidth and so on. Many manufactures have build SDR’s; ICOM, AOR, TENTEC, WInRadio, etc. Until recently, a SDR would set one back a pretty penny.

Then there is the Ultra Cheap Software Defined Radio based on a RTL2832 USB Television tuner.  Someone figured out that the TV tuner covers from approximately 60 MHz to 1700 MHz and it’s raw output can be used by any number of free, open source software programs.

I found a Newsky TV28T USB tuner on Amazon for about $30.00.  I figured, what the heck, it is only thirty dollars.  There are some sources that have the ezcap EzTV668 on dealextreme for less than $20.00, however, I could not find that particular model.  In any case it looks like a fun project.
