I have heard many people asking questions recently about using SDR # software with RTL-SDR dongles and other Software Defined Radios. I personally have 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: http://tylerwatt12.com/tips-for-using-sdr/
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.
Good Luck and 73!
