• Pi-Hole: A small computer to block web advertisements on your home network.
• APRS I-Gate: Program your Raspberry Pi to transfer APRS packets from your to/from your radio and the Internet.
• GQRX: A small computer host for your USB software-defined receiver.
• Requirements
  • Pi
    • Pi-ZEROW: A single-core machine for simple things like Pi-Hole. Often available for $5 on sale.
    • PI-3B+ A multi-core, fully-featured Pi, usually $35.
    • PI-4 This is the latest realease. Not all features are complete and it might require cooling to be reliable.
    • MicroSD card (32GB)
    • Power supply. Don’t cheap-out here and try to use your old cellphone charger. Get a higher-current model that has the correct connector for your Pi.
  • Operating system
    • Start at http://www.raspberrypi.org and look in the downloads section.
    • Raspbian is good. NOOBS is simpler but doesn’t expose all the features. Others exist, for example, Buster.
    • You’ll need a software tool to put the operating system on your SD memory card. If you are running Windows, Win32diskimager is a popular application.
• Pi-Hole: Utilizes a Rapberry Pi to pull advertising out of your web browsing! Read the documentation here
  • Get the software from github, here.
  • Paul recommends using these commands on your Raspberry Pi to install:
    • git clone –depth 1 https://github.com/pi-hole/pi-hole.git Pi-hole
    • cd “P1-hole/automated install/”
    • sudo bash basic-install.sh
• APRS IGATE
  • Another good use for the Raspberry PiZero-W
  • Prebuilt images can be found here.
  • Paul has additional experience with this if you have questions.
• GQRX
  • You probably need to be running this on a Raspberry Pi 4 because it is processor intensive.
  • The software is actually available through the normal raspbian installer. Click on Preferences–>Add/Remove software and search for GQRX.
  • Paul recommends the Nooelec tuners, such as the NESDR SMArt4 v4 because of their shielded aluminum cases and temperature-stabilized oscillators. Look around the site and check their specifications for a tuning range, etc. that meets your needs.
• Questions? paul@conspiracy.net
• Thanks again to Paul Bilke for giving us some ideas.
