Introduction¶ GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic and commercial environments to support both wireless communications research and real-world radio systems. GNU Radio is licensed under the GNU General Public License (GPL) version 3 or later. All of the code is copyright of the Free Software Foundation. Content¶ 0. Registration for GRCon16 is now open! I. If you've never touched GNU Radio before, these pages will get you started with a running installation of GNU Radio and will show you how to take your first steps with this software radio tool. II. GNU Radio has two manuals: one for the C++ API and another for the Python API. Documentation on this wiki: III. IV. V. VI. Related projects¶ Other Languages¶

R820T Archives Over on the SDRSharp Yahoo group, HB9AJG has posted an interesting report in a PDF file containing some measurements (Note you will need to be a member of the group to download the file titled “Some Measurements on E4000 and R820 Tuners.pdf”. Here is a Direct Mirror of the file.) quantifying the performance of both the E4000 and R820T RTL-SDR DVB-T dongles. See the discussion in the Yahoo group here.

Ham It Up vs SDR UP 100 The Ham-It-Up and the Up 100 are the two cheapest shortwave adapters available: direct competitors at 50 USD (including shipping). For this review, I purchased the Ham-It-Up and received the Up-100 for free for testing. Shipping and customer service The Ham-It-Up comes from the States with tracked shipping; you get emails where it is, but when the package leaves the US no more tracking info available.

Introductory Tour of the GNU Radio Project Before you read too far, I have produced a coding guide: Blocks Coding Guide. Don't overlook it. Introduction I am writing this guide because GNU Radio is a great tool that can easily be overlooked. The documentation is poor and just getting started is not obvious.

kochmorse - Koch Morse Tutor for Linux KochMorse is a easy to use morse tutor (trainer) for Linux using the Koch-mehtod. It provides a clean and modern graphical interface. The current release (version 0.99.x) is full featured and stable. I've tested it under Fedora and Ubuntu and it works well. Software Defined Radio for Mariners: Reducing electrical noise - You can use alu foil, but make sure it touches the metal part of the USB plug. - Remove the metal support from the USB extension cable on the end where you connect the RTL stick. This will eliminate noise picked up by the USB extension cable. - If you have a spare car battery, connect the metal part of USB plug to the negative terminal. - Mobile operation or no car battery? Wrap the center conductor of coax around the metal part of the USB plug, then place the stick in the middle of coiled coax. Testing setup Your antenna receives noise and signal. Without an antenna any signal received is by the RTL stick and the cables, and you do not want that.For this test: Nooelec RTL-SDR 820T stick, max gain, no antenna.
