WebSDR node based on a Raspberry PI
The idea behind a WebSDR is to run your RTL-SDR QO-100 receiver on a remote Raspberry Pi (perhaps mounted close to the antenna on your roof etc). The Pi runs custom WebSDR software that has been created from scratch by [Radio Electronics] specifically for monitoring Es'Hail-2. Then you can access your QO-100 receiver from any device on your network that has a web browser (computer/phone/tablet etc).

DSD for Raspberry Pi
I decided to share my successes/failures so far in compiling DSD on the Raspbian Wheezy distribution for the Raspberry Pi.
Shrink/Expand Raspberry Pi Filesystem Images
Shrink/Expand Raspberry Pi Filesystem Images
This post documents a few tricks I found useful when making SD card images for Raspberry Pi projects, to minimize file size and download times while making full use of the SD card space. These instructions work for Raspbian Stretch images; not sure about older or newer versions.
The first time a Raspbian system boots, it runs a program to expand the filesystem to use the full size of the SD card. So, when you are using a Raspberry Pi system you automatically get the benefit of the full (e.g., 8GB) SD card size. The problem is that when you copy the card image you copy the whole 8GB, even if only 2GB is in use. That takes up a lot of unneeded space, and lengthens download times.
So, the first task is to reduce the size of the image to a minimum.

Build CubicSDR under Debien Jessie on the Raspberry Pi3
Ham Radio - SDRPlay running with CubicSDR on a raspberry Pi 3
It's slow, but it works! Follow my build instructions on my sdrplay on linux video linked below. You also have to make a change in raspian to get pulse audio working. That's detailed in the blog entry as well as in this video.

Building a network capture probe with Raspberry Pi
The great news is you can do it easily by installing tshark on your system and running a simple script from one of our developers, Tom. The even better news is that you can lower the memory footprint of doing the capture with tshark by using Wireshark’s included packet capture process, dumpcap. In an embedded environment like a Raspberry Pi, this allows you to bypass tshark’s processing and send the resulting capture directly to CloudShark.

Raspberry Pi RTL-SDR Broadcastify
Raspberry Pi RTL-SDR Broadcastify
These instructions show you how to purchase and setup a completely self contained Raspberry Pi with an RTL-SDR stick(s) to broadcast a live audio feed to Broadcastify.com
These instructions have been verified and tested as working on a Raspberry Pi 2 Model B Project Board - 1GB RAM - 900 MHz Quad-Core CPU. Two separate feeds running rtl_fm broadcasting both AM aviation and FM business frequencies simultaneously have been verified as working just fine.

RASPBERRY PI REMOTE RTL-SDR GUI SOFTWARE: MNM4SDR
Recently RTL-SDR.com reader Slaven Krilic wrote in to use to announce his project called MNM4SDR which stands for Monitoring Network Manager for RTL-SDR. The software allows you to set up a remote Raspberry PI embedded computer with an RTL-SDR dongle attached and access it remotely through a Windows PC GUI.
Unlike other server software such as rtl_tcp, raw IQ data is not sent over the network. Instead audio is first compressed in lossless FLAC or OGG formats. This allows you to use much slower network or internet connections. The software also allows you to collected RF scans over a large bandwidth in a similar way to rtl_power.
The software works over an SSH connection and requires that you have RTL-SDR and VLC set up on your Rasperry Pi first.

RTL-SDR and a Raspberry Pi
Showing how to perform a simple record and replay attack on 433 MHz ISM band devices using nothing more than an RTL-SDR and Raspberry Pi. The Raspberry Pi runs RPiTX which allows it to transmit from a GPIO port with just a wire attached. No extra transmitter hardware is required.
What is RTL-SDR?
What is RTL-SDR?
RTL-SDR is a very cheap software defined radio that uses a DVB-T TV tuner dongle based on the RTL2832U chipset. With the combined efforts of Antti Palosaari, Eric Fry and Osmocom it was found that the signal I/Q data could be accessed directly, which allowed the DVB-T TV tuner to be converted into a wideband software defined radio via a new software driver.
