![]() To tune to 500 kHz (with an upconverter and appropriate offset shift set (discussed later)) we would tune to 000.000.500.000. For example to tune to a radio station at 88.6 MHz we would enter 000.088.600.000 into the frequency input. The first section represents GHz frequency values, the second MHz, the third kHz and the last Hz. The frequency input is divided into 4 sections with each section containing 3 values (e.g. You can either click on the tops and bottoms of each individual number to increase or decrease the value, or simply hover over the number you want to change and use the mouse wheel to alter the value. ![]() Use the mouse to set the desired frequency you wish to listen to here. See further down for more information about these settings. In here you can change settings like the sample rate (bandwidth) and RF gain. Be sure to NOT select RTL-SDR/TCP unless you are using a remote server with rtl_tcp.Ĭlicking this button opens up the configure menu. If you are using an RTL-SDR, select RTL-SDR/USB. This is a drop down menu which is used to select the SDR input device being used. This button is used to start and stop the SDR. To optimize processing of the signal you need to adjust these DSP settings. Most of the settings found in the main windows of SDR# affect the software digital signal processing (DSP) side of things. To optimize reception, you need to adjust settings in this window. ![]() In here are settings to control things like the RF gain and sample rate / bandwidth of the RTL-SDR. All hardware side settings can be found in the Configure Menu window which can be accessed with the cog icon. Note that there is a distinction in SDR# between settings that affect the software side, and settings that affect the hardware side. Set the 'Mode' to the correct setting for the signal that you are listing to.Turn off the “Snap to grid” setting, or adjust the PPM offset accordingly.Enable the “Correct IQ” setting to remove the center spike if using an R820T/R820T2, or enable “Offset Tuning” in the configure menu if using an E4000/FC0012/13.Reduce the range slider on the right of the SDR# window to about -70 (for RTL-SDR dongles).Increase the RF gain from zero to a higher value in the configure menu.Here we have highlighted the main parts of SDR#Īfter opening SDR# for the first time, we suggest that you immediately remember to perform the following steps (if you don’t know what some of these steps are, continue reading further below for more information): Upon opening SDR# you'll be greeted with the screen shown below. Below we explain some of the settings and displays in SDR#. To install SDR#, go through our Quickstart Guide. SDR# is currently the most popular SDR program used with the RTL-SDR. ![]() This is an excerpt from our book on RTL-SDR which we've decided to post given that many new users struggle to understand all the settings in SDR#.
