SignalsEverywhere: Running PlutoSDR over an Ethernet Network Connection

Over on YouTube Corrosive from his SignalsEverywhere channel has just uploaded a new video showing us how to run a PlutoSDR over an Ethernet connection. As the PlutoSDR does not have an Ethernet port built in he uses a USB to Ethernet adapter. The rest of the video shows how to configure the IP address settings in the PlutoSDR config files, and in Windows.

The PlutoSDR is a low cost (typically priced anywhere between $99 - $149 depending on sales) RX/TX capable SDR with up to 56 MHz of bandwidth and 70 MHz to 6 GHz frequency range. It also has an onboard FPGA and ARM Cortex-A9 CPU which can be used to run programs on the PlutoSDR itself.

It is possible to run streaming software such as OpenWebRX directly on the PlutoSDR's CPU. Using an Ethernet connection can help with having enough network bandwidth to serve multiple users over the internet.

SingalsEverywhere: Running OpenWebRX on a PlutoSDR with PlutoWEB Firmware

Over on YouTube Corrosive from the SignalsEverywhere channel has uploaded a new video that shows how to install the the PlutoWEB Firmware on a PlutoSDR, which allows OpenWebRX to run directly on the PlutoSDR itself. OpenWebRX is a SDR streaming platform that enables people to connect to the SDR remotely over the internet. Multiple users can access the SDR at the same time as well. Many public OpenWebRX servers running on KiwiSDRs can be found at sdr.hu as the KiwiSDR uses it by default.

Corrosive's video shows us how to install PlutoWEB which is an unofficial firmware package for the PlutoSDR. It comes preinstalled with many programs such as OpenWebRX and dump1090. He then shows how to set up OpenWebRX and then shows a demo of it in action.

SignalsEverywhere: SDR Console V3 Transmitting with PlutoSDR

Over on YouTube Corrosive from the SignalsEverywhere YouTube channel has uploaded a video showing us how to use SDR-Console V3 and a PlutoSDR to transmit ham radio voice. In the video he sets his PlutoSDR to transmit from his microphone at 445.5 MHz, and to receive at 434 MHz. He is then able to talk to a friend using a handheld who is receiving at 445.5 MHz and transmitting at 434 MHz.

SignalsEverywhere: SDRAngel PlutoSDR Transmit Tutorial

Over on his YouTube channel SignalsEverywhere, Corrosive has uploaded a new video tutorial showing us how to transmit with a PlutoSDR and SDRAngel. His tutorial goes over the initial set up steps, selecting a modulator and changing modulator settings. He then goes on to demonstrate transmitting CW Morse code, using a CTCSS squelch tone and transmitting a Robot36 SSTV image via Virtual Audio Cable and MMSSTV.

Using Two PlutoSDR’s for Full Duplex Packet Radio Communications

Over on his channel SignalsEverywhere, Corrosive has uploaded a video showing us how we can create a full duplex packet radio communications system using two PlutoSDRs. Full duplex is the ability to transmit and receive at the same time. A single PlutoSDR is only half-duplex/simplex because it can only either receive or transmit at any one time. The PlutoSDR is a low cost (typically $99 - $149) RX/TX capable SDR with up to 56 MHz of bandwidth and 70 MHz to 6 GHz frequency range. 

On his video Corrosive explains how full duplex operation is desirable for amateur packet radio communications as it allows for faster and more continuous exchanges.  Demonstrations are performed with his PlutoSDR, SoundModem, EasyTerm, and SDRAngel. Later in the video he also speculates how it might be possible to do things like IP networks via the amateur radio bands with full duplex SDRs.

SignalsEverywhere PlutoSDR Videos: Applying the Frequency Extension and Dual Core CPU Hacks and Running on SDR#

Over on the SignalsEverywhere YouTube channel, Corrosive has uploaded two new videos about the PlutoSDR. The PlutoSDR is a low cost (typically $99 - $149) RX/TX capable SDR with up to 56 MHz of bandwidth and 70 MHz to 6 GHz frequency range. It also has an onboard FPGA and ARM Cortex-A9 CPU.

By default the bandwidth and frequency range of the PlutoSDR is limited to only 20 MHz and 325 MHz - 3.8 GHz. A minor hack which requires some commands to be input via a terminal screen is required to unlock its full potential, and in the first video Corrosive runs through how this hack can be applied. He also shows an additional hack which unlocks a second CPU core which can be useful for increasing the available CPU power for apps running on the PlutoSDR's ARM processor.

In the second video Corrosive shows how to install the PlutoSDR SDR# plugin, which allows the PlutoSDR to run in SDR#. He then shows how to actually use the plugin to connect to the PlutoSDR.

Using a LimeSDR / PlutoSDR to Transmit Digital Amateur Television with DATV Express

Over on YouTube Corrosive from channel SignalsEverywhere has uploaded a new video in his series on Digital Amateur Television (DATV). The new video shows us how to use a transmit capable SDR like a LimeSDR or PlutoSDR to transmit DATV with a free Windows program called DATV Express.

In the video he explains the various transmit and video encoding settings, and then demonstrates the signal being received on SDRAngel with an RTL-SDR (which he explained in his previous video)

New Custom Firmware for the PlutoSDR with Several Linux SDR Programs Pre-Installed

The PlutoSDR is an Analog Devices $99 - $149 RX/TX capable SDR with 20 MHz of bandwidth and a 325 MHz to 3.8 GHz frequency range that is software hackable to 56 Mhz of bandwidth and a 70 MHz to 6000 MHz frequency. It has an on board Xilinx Zynq Z-7010 FPGA, which has a built in dual core ARM Cortex-A9 processor as well. This processor is capable of running Linux and Linux SDR software on the PlutoSDR itself. PlutoSDR's can be purchased directly from Analog Devices, or via ArrowDigiKey or Mouser.

Recently "Lama Bleu" has been working on a custom firmware image for the PlutoSDR. Installing custom firmware allows you to load up a pre-configured Linux system which already has a bunch of useful software installed. He writes that his version is not designed to have a nice GUI, but rather focuses on scripting and data acquisition software. A list of software pre-installed to the image is shown below:

To access these tools you simply connect to the PlutoSDR via a network connection and SSH. With some of the tools installed it is possible to do things on board the PlutoSDR like recording signals, demodulating signals, transmitting CW, stream demodulated audio over a network, plot the spectrum on the terminal, create an online SDR with OpenWebRX, do a long spectrum scan and transmit DATV. 

An alternative custom firmware is PlutoWeb which we posted about in the past. This image is designed for creating a web interface GUI, and for running streaming software such as OpenWebRX.
