Remoting Your SDR

Dongles (RTL-SDR, AirSpy, SDRPlay, etc)

rtl_tcp

an I/Q spectrum server for RTL2832 based DVB-T receivers

SpyServer

Airspy R0, R2, Mini, Airspy HF+, RTL-SDR and AOR radios can be used as a high performance SDR receiver capable of streaming separate chunks of the spectrum to multiple clients over the LAN or the Internet.

sdrpp –server

SDR++ will operate as a server to provide the IQ stream over a network connection to another instance of SDR++ running on a different device elsewhere ona  network - including over an internet connection.  Default port is 5259.

OpenWebRX

OpenWebRX is an open source web-based software defined radio application that allows users to share access to one ore more SDR devices using a browser.

“Software defined radio”: All processing is done in software, using digital signal processing (“DSP”) technology.

“Web-based”: Users do not need to install anything on their PC; all that’s required to be able to use OpenWebRX is an HTML5 capable browser.

“Shared access”: Multiple users can use the same receiver at the same time, and can listen to different frequencies and modes (some restrictions apply).

“Open source”: The code for all parts of OpenWebRX is available under free and open source (“FOSS”) licenses.

OpenWebRX+

OpenWebRX+ adds many features missing from the original OpenWebRX, such as noise reduction, tuning steps, scanner, keyboard shortcuts, improved user interface and maps, and decoders for many digital communication protocols. Please note that the following document covers both the original OpenWebRX and the extended OpenWebRX+. Features specific to OpenWebRX+ are marked so.

PhantomSDR-Plus WebSDR v2.0.0

PhantomSDR-Plus is a high-performance WebSDR server that can handle hundreds of concurrent users. This enhanced version focuses on Linux optimization and provides significant improvements over the original PhantomSDR.

Plug and Play Options Hardware/Software Combos for the lazy that don’t want to setup anything and just buy stuff.

KiwiSDR

KiwiSDR Independent SDR Network Receivers are stand-alone SDR (software-defined radio) receivers that operate across a frequency range of 10 kHz to 30 MHz, encompassing very low frequency (VLF) to high frequency (HF) bands. These receivers come pre-installed with OpenWebRX and feature an integrated GPS receiver. Its ease of use and comprehensive features make it one of the best HF SDRs available. The Kiwi SDR2 is different from other SDRs. It is a standalone device that attaches to your local network and is optionally accessed through the Internet. A browser is used to connect to the user interface. Most other SDRs generate raw IQ data and need to be connected directly to a PC or laptop running OS-specific, installed software.  (Open Source The licenses used are mostly a mix of GPL v2.1/3 and MIT.)

SDRPlay nRSP-ST (proprietary)

The nRSP-ST is a truly “plug and play” integrated, networked general coverage receiver which combines a receiver, a host computer and a whole lot more all in one box. Apply power and connect to the internet and the nRSP-ST can be accessible from anywhere. The receiver comprises a full-featured 14-bit software defined radio. It offers up to 10MHz of spectrum visibility anywhere between 1kHz and 2GHz. The nRSP-ST is ideal as a stand-alone device with remote connections made accessible via its Ethernet or WiFi interfaces. The unit supports a choice of three data transport modes to suit the available network bandwidth of LAN or WAN connectivity. It is ideal for use in a low noise location or where connections to large outdoor antennas are feasible. Large IQ files can readily be stored on a local storage device. SDRplay provides free companion SDRconnectTM client SDR software for Windows, MacOS and Linux platforms, and the nRSP-ST provides a built-in web-server for remote access from most up-todate web browsing capable devices, including Android/iOS tablets and phones.

Segment 2 (Announcements & Feedback)

YouTube Comment on SDR++Brown Video from @SDR-DXobserver8

Thanks for the video. You can decimate the SDR by 4 to obtain a good decode and no stuttering of the audio. 400 kHz BW is suffcient enough for shortwave bands. 73.

YouTube Comment on CQRlog Video from @MrRicksho

please help witht he steps.. i am trying to install on Ubuntu 22.04…..

YouTube Comment on Commodore OS Vision 3 Video from @RigoMuniz

Do I need a new computer to install it? I would like to see the minimum specs. I have one old Windows Xp (Hp), an old Windows 10 Dell, a new Dell with Windows 11 (home user) and Imac G3 (2023) I am planning on getting the C64 ultimate (i am not sure which one)  Can it run on any C64 ultimate model, or it has to be a Pc version?

I haven’t managed to download a copy of V3 yet that passes it’s own integrity test.
