Comment on SignalsEverywhere: What SDR To Buy? Choose the Right one For You by FlexMe

How about a WEB SITE with images and text, over videos.

Not interested in videos or podcasts or anything like it. Just a nice clean web site I can visit for info. Images if you need them.

Also don’t want to support y**t*be with their anti group think policies by banning voices they don’t like which don’t agree withe their lib agenda.

Troubleshooting Help • Re: need help plugins

If you are use SDR# on linux

You have to put magic line in the sdrsharp.exe.conf
after this section </appSettings><frontendPlugins>

and to copy dll to /Release folder

I am not 100%sure about this, i also try to install plugins but returning me error

WeFAX Jagged Lines


Is it possible to get the vertical lines to be properly straight or am I expecting too much from an analog HF transmission :)

A RTL-SDR and Pi 3 Based Ground Station for Simulated CubeSats

CubeSats are small and light satellites that can these days be built and launched into orbit by almost anyone with a small budget of roughly $40,000. They are a great way for schools and other organizations to get into a space based technology project. A "simulated" CubeSat is one that is not designed to be really launched into space, and is made from low cost hardware. The idea is that simulated CubeSats can be used as tools to help demystify the inner workings of satellites to the public and help CubeSat builders get experience and competence before building the real thing.

A Simulated CubeSat made from a Solar Panel board, Pi Zero, UPS and Tranceiver.

A team from AMSAT have been working on creating open source CubeSat simulator hardware and software. In order to demonstrate the RF capabilities of the simulator a ground station simulator is also required. Recently the team have uploaded instructions on creating a Raspberry Pi and RTL-SDR based ground station.

If you're interested in the CubeSat simulator hardware itself, there was a presentation held back in 2018 that may be of interest to you. According to the presentation somewhere between 30% - 50% of CubeSats fail as soon as they're deployed, so building competence with simulated hardware is a good goal.

Decoding FT8 with an RTL-SDR Blog V3 in Direct Sampling Mode

Over on YouTube user ModernHam has uploaded a useful tutorial showing how to use our RTL-SDR Blog V3 dongles for FT8 monitoring. The RTL-SDR Blog V3 has a built in direct sampling circuit which allows for reception of HF signals without the need for any upconverter. FT8 is an amateur radio weak signal digital communications mode which can be received all around the world even with low transmit power.

In his setup he uses SDR# and Virtual Audio Cable to pipe audio to the WSJT-X decoder. His video goes through all the steps and settings that need to be set and then shows a demo of some signals being received. ModernHam also has another video uploaded a few days earlier which is a more general introduction to FT8 decoding.

If you're interested we uploaded a tutorial last year that shows how to set up a Raspberry Pi 3 based FT8 decoding station with a V3 dongle.

How to install the plugins to SDR# Linux version?

I find /Release/SDRSharp.exe.config and add there magic line for the plugin.
Also add .dll file to /Release folder

After start SDRSharp with mono i receive error
Error loading 'SDRSharp.Frequency.Scanner.Frequency.Scanner.Plugin
Could not load type Scanner.Frequency.Scanner Scanner.Frequency.ScannerPanel from assembly Scanner.Frequency.Scanner Version= Culture=Neutral PublicKeyToken=null
And i have similar errors to every plugin which i try to install.

The RadioInstigator: A $150 Signals Intelligence Platform Consisting of a Raspberry Pi, RPiTX, 2.4 GHz Crazyradio and an RTL-SDR

Circle City Con is a yearly conference that focuses on information security talks. At this years conference Josh Conway presented an interesting talk titled "SigInt for the Masses Building and Using a Signals Intelligence Platform for Less than $150". Josh's talk introduces his "RadioInstigator" hardware which is a combination of a Raspberry Pi, CrazyRadio and an RTL-SDR all packaged into a 3D printed enclosure with LCD screen. The idea behind the RadioInstigator is to create a portable and low cost Signals Intelligence (SIGINT) device that can be used to investigate and manipulate the security of radio signals.

The RadioInstigator makes use of the RPiTX software which allows a Raspberry Pi to transmit an arbitrary radio signal from 5 kHz up to 1500 MHz without the use of any additional transmitting hardware - just connect an antenna directly to a GPIO pin. Connected to the Pi is a CrazyRadio, which is a nRF24LU1+ based radio that can be used to receive and transmit 2.4 GHz. And of course there is an RTL-SDR for receiving every other signal. Josh has made the plans for the RadioInstigator fully open source over on GitLab.

In his talk Josh introduces the RadioInstigator, then goes on to discuss other SDR hardware, antenna concepts and software installed on the RadioInstrigator like RPiTX, GNU Radio, Universal Radio Hacker, Salamandra, TempestSDR and more.
