1 Project Scope

The goal of this project is to set up a remote controlled shortwave receiver station that is connectable via HAMNET.

First, I installed two Chinese wideband preamplifiers. Later I heard that there was a special kit from Box73 / FUNKAMATEUR that did the job much better. My observation with the Chinese preamp was that the input of the SDR was highly overloaded, so I needed one with an adjustable amplification. Please check the instruction: http://www.box73.de/download/bausaetze/BZ-100.pdf

Once deployed, I understood that I needed to install Pavel Demon's firmware. Since the deployment at DB0MHB is a little out of reach, I needed to log into my Red Pitaya and make sure that the installation files go to the right place. I decided to build a deb package so that this job was easier.

The final goal is to have a recording / monitoring receiver that can fully be remote-controlled.
