Types of CRC Errors CRC8 – Header Only CRC32 – Full Frame The building block of the DVB carrier is the BaseBand Frame (BBFrame). CRC8 and CRC32 errors will provide two separate levels of error checking, each is […]

Stepper Motors with a Raspberry Pi

The latest project is to make an auto-acquire satellite antenna using a Raspberry Pi for the controller and motor driver. Commercial auto point satellite antennas cost over $20K so I thought it will be good to see if I can make one for a few hundred dollars. The first step is to drive a stepper […]

F Type Compression Connectors

F-type compression connectors are used extensively throughout the satellite industry and it is vital that when you are terminating a good connection is made. Here are some simple steps to guide you through the basics of preparing the coax and terminating it with an F-type connector. I would recommend these tools (it is worth the […]

LNBs Explained

The LNB wiki page has been updated and I’ve tried to explain what an LNB is, what it does and how it does it. Getting the correct Local Oscillator (LO) is vital for  your VSAT system receive so I’ve an example of how to select the correct LNB LO. You can read all about LNBs […]

Site Surveys for Satellite Installs

There are quite a few things to consider when surveying a site for a satellite installation and often this is left to a sales rep or inexperienced personnel.
