Build a PiGate

WelcomeHow it worksBuild a PiGatePiGate RMSOrder Completed PiGate

Here are the pieces you’ll need to build a PiGate.

  • A Raspberry Pi mini-computer, Model 3, 3B+, or 4 – earlier versions may work but will not be supported
  • Even a Pi Zero WH works!
  • An 16Gb (minimum) Class 10 mini-SD card for the Raspberry Pi
  • A TNC-Piavailable from MFJ or the TNC-Pi9k6 from the WVCARC
  • Will also work with the Direwolf virtual TNC and a sound card like a SignaLink USB
  • The PiGate software is downloaded from the downloads page.
  • A cable for your VHF radio (some designs are available from the downloads page)
  • A nifty 3D printable case for the completed unit available from the downloads page or

Assembly is as simple as plugging the TNC-Pi into the Raspberry Pi (or using Direwolf and a sound card device), inserting the mini-SD card with the loaded software, and plugging the custom data cable into your VHF radio.  This is an easy plug-and-play device!

NOTE: When assembling the PiGate, put several layers of electric tape on the top of the Raspberry Pi USB connectors to insulate the metal housing from the pins on the bottom of the TNC-Pi board.

If you will be using HF radio to connect to a WinLink2000 RMS station, you must have a USB to serial dongle and a cable to your PACTOR modem.  I recommend this dongle:   These dongles can also be bought from eBay for a lesser price.

To make your project easier, I recommend using this application to copy the PiGate software image to your SD card,

I recommend this GPS receiver.  It works perfectly with the PiGate.  To make your life easier, GET A GPS!  It’s less than $30!
