Gnuradio ssb receiver. This takes voice from the laptop audio and is bandpass filtered to 300-2700Hz. 6 – with the following changes: Added frequency entry widget to change USRP frequency Also created AM and narrow FM versions You can get the GRC files here. Simulation example: Single Sideband transceiver This tutorial explains how a Single Sideband (SSB) signal can be generated and received. Dec 23, 2021 · RTL-SDR for 40M SSB LSB on GNU Radio Fig. Simple GNU Radio Companion examples. 8 SSB Opt USB Spectrum for Voice Figure 6 shows a similar GNU Radio modulator as Figure 3, except this time the information source is an audio source block. Watch as we analyze the signal using a spectrum analyzer and SDR software! Aug 19, 2025 · An innovative project has emerged from the world of amateur radio, as Paul Maine successfully created a single sideband (SSB) receiver utilizing GNU Radio and an RTL-SDR dongle. Dec 30, 2021 · Fig. My third Getting Started GNURadio project is a SSB receiver. There are numerous references for SSB transmitters and receivers, such as the ARRL Handbook, or the Philips AN1981 application note. We generate an SSB signal in GNU Radio, transmit it using the HackRF SDR, and successfully receive it with the RTL-SDR. The transmitter uses the Filter method. Here, the Q channel is subtracted from the [I channel + Hilbert Transform]. His work, which he documented in a comprehensive video, provides an accessible guide for enthusiasts looking to explore this technology. We will use it to learn more about GNURadio and decode single sideband. To set this up he uses an Orange Pi One Plus single board computer which runs several GNU Radio based digital signal processing flow graphs. In the video, Paul explains the concept and mathematical principles behind SSB by showing how to create an SSB receiver using GNU Radio and an RTL-SDR. First we start with the most basic example of SSB. Receivers are shown for the Filter method and the Weaver method. Note that the AM, FM and SSB/CW are separate receivers because it seems infeasible to implement the mode change in GNU Radio Companion. This example lacks the filtering normally used with these methods to be as minimal as possible. E17 Create Single Sideband Receivers with GNU Radio and RTL-SDR Paul Maine 854 subscribers Subscribe Apr 10, 2010 · New update of the simple receiver – version 0. 8 shows the Weaver method RTL-SDR FM Receiver B200-B205mini FM Receiver E310 FM Receiver Intermediate/Advanced Tutorials Core GNU Radio Mechanics Stream Tags Polymorphic Types (PMTs) Message Passing Virtual Sinks and Sources Importing Libraries Modulation and Demodulation Narrowband FM Single Sideband (SSB) QPSK Mod and Demod BPSK Demodulation M-ASK, M-PSK and QAM-M Mod Gqrx is an open source software defined radio receiver (SDR) powered by the GNU Radio and the Qt graphical toolkit. His tutorial includes adding several tuning sliders in the GNU Radio GUI as well. He created an SSB receiver and, lucky for us, he documented it all in a video you can see below. Gqrx supports many of the SDR hardware available, including Airspy, Funcube Dongles, rtl-sdr, HackRF and USRP devices. Slider controls are added to adjust RTL-SDR rf_gain, volume and 40M rx frequency.

Dec 2, 2017 · This article shows how to build a simple GNURadio SSB Receiver. In AN1981, Fig. He walks through how to Aug 26, 2025 · Thank you to Paul Maine for writing in and sharing his latest tutorial video, which explains how Single Sideband (SSB) modulation works. Aug 19, 2025 · [Paul Maine] was experimenting with GNU Radio and an RTL-SDR dongle. The demo uses the Universal Software Radio Peripheral (USR May 5, 2010 · Simple receiver and transmitter examples implemented using the GNU Radio Companion (GRC). Nov 2, 2010 · GNU Radio combined with Qt for GUI is quite awesome! Future plans The architecture of the receiver is based on my GRC examples that use two filters: a frequency xlating filter for tuning within the received spectrum and a second low pass or band pass filter that performs channel filtering and decimation from 250k to 50k. They work via files recorded to disk using your computer's microphone. Apr 10, 2010 · Demo of a simple SSB/CW software defined radio receiver implemented using the GNU Radio Companion. Figure 7 shows the I & Q information signals and Figure 8 shows the SSB USB output spectrum. The flow diagram demonstrates playback of an IQ bandwidth file, frequency translation, AGC and W July 7, 2020 Step-by-step Guide to Creating a GNU Radio Based QO-100 SSB Receiver Thank you to M Khanfar for submitting his video that shows a step-by-step tutorial on building your own SSB receiver in Windows GNU Radio for QO-100 satellite reception. Jun 24, 2020 · Over on his blog F1ATB has uploaded a post explaining how he created an RTL-SDR or HackRF based remote SSB receiver controllable with an internet browser. 7 SSB 40M LSB Receiver Spectrum at 7175KHz Figure 6 shows a 40M SSB LSB receiver. ewr ynv lve qwx xcn woi znx irj qwi onl squ yak jju fsq yew
