Custom Cases  Brent Parker, W8XG, can make a custom case, like the pictures shown of a case that he made for me.  Contact him at bparker@pwg.net or see his website at www.PiGateCase.com

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.

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 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
  • Optionally, a TNC-Pi9k6 9600 baud capable TNC, also from Coastal Chipworks
  • 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 or PiGateCase.com


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 copy the PiGate software image to your SD card, https://sourceforge.net/projects/win32diskimager


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.

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