Meet Quadra: A $35 Complete Mini-PC for Amateur Radio (and more!)

Update: Now includes popular ham radio apps pre-installed. HamClock, WSJT-X, js8call, GridTracker, Pat (Winlink), and the flDigi suite are all ready to use out of the box, plus an installer to add more easily.

Not just a raw board, Quadra is a complete modern Linux computer that can be used as a server or light-use desktop. It includes the case, heatsink, power adapter and HDMI cable. Just plug into a TV or monitor and a keyboard/mouse. No SD card needed as the OS (Debian Bullseye 64-bit) is pre-flashed in internal memory. A great option instead of Raspberry Pi when you don't need the 40-pin I/O header or want something more affordable that doesn't require assembly.

Due to unprecedented demand from the YouTube video by Jim Heath (W6LG), we are out of stock of the HamClock Bundle and Quadra until mid-December. Sorry for the short delay! We will flash them with the latest firmware, test, and ship Priority Mail as fast as we can starting then. You'll receive an order confirmation now and another when it is on its way with tracking information. Orders for accessories only will ship quickly, usually same or next day.
