Software Defined Radio (SDR) information

Software-defined radio (SDR) is a radio communication system where components that have been typically implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded system. While the concept of SDR is not new, the rapidly evolving capabilities of digital electronics render practical many processes which used to be only theoretically possible.

Here are a few SDR radio information links. I will add more as I find them or other people recommend them:

Wikipedia link to SDR :

A blog about RTL-SDR (RTL2832U) and cheap software defined radio:

SDR Radio roundup listing of Radios:

Listen to some SDR radios around the world:

Ham Radio Science - some good SDR info:

SDR is a brief overview of several SDR transceivers on the market:

Very Good SDR book!

The Hobbyist's Guide to the RTL-SDR: Really Cheap Software Defined Radio
This book is a collection of articles from an internet blog, along with many added lists of softwrae and other SDR resources. It is from the authors of the RTL-SDR Blog and has detailed articles on RTL2832U RTL-SDR as well as other SDR's.

SDR software links:


SDR # (sharp) - SDR software that works well with the RTL-SDR dongle:

Using SDR # software with RTL-SDR dongles and other Software Defined Radios can seem complicated. I personally struggled with finding guidance on how to optimize the many parameters in the SDR# software. 
Well I found a link to a great blog posting that does a nice job explaining many settings in SDR#. Find that blog post here:

Using SDR# is pretty cool once you understand the settings and get them adjusted properly. So don't give up on SDR# or your dongle without trying some of the tips in this article.
