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


  • A Raspberry Pi mini-computer, Model 2, B+, or 3
  • An 8Gb (minimum) Class 10 mini-SD card for the Raspberry Pi
  • A TNC-Pi from Coastal Chipworks (http://tnc-x.com/TNCPi.htm) either a kit or completed unit
  • If using a Raspberry Pi prior to the model 3, you'll need a WiFi dongle like https://www.adafruit.com/products/1030
  • The PiGate software 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


Assembly is as simple as plugging the TNC-Pi into the Raspberry Pi, 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!

To make your project easier, I recommend using this application to burn the PiGate software image to your SD card, https://sourceforge.net/projects/win32diskimager

I recommend this cable for powering the PiGate during field operations https://powerwerx.com/usbbuddy-powerpole-usb-converter-device-charger


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: https://www.tripplite.com/keyspan-high-speed-usb-to-serial-adapter~USA19HS These dongles can also be bought from eBay for a lesser price.

I recommend this GPS receiver.  It works perfectly with the PiGate.
