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.
