It is a recent public domain circuit from (HA7DCD, Zoltan) for the Raspberry Pi 3 to enable you to turn your Raspberry Pi into a QRP wspr transmitter with variable power up to a 100mW signal using the free WsprryPi and Raspbian software. We are kitting an easy to build through hole module that will plug into the GPIO connector on the top of your Raspberry Pi. Currently the board supports 20m, but other bands are planned. Load and configure the software, connect an antenna of your choice, and users with internet access can watch results in real time at wsprnet.org. Once set up via direct connection, you only have to have the power and antenna connection to the Pi, using Raspbian’s built-in VNC to control keyboard/mouse/monitor functions of the Raspberry Pi with your tablet, desktop, or smartphone. The kit Is 100% thru hole components. The tools required are a soldering iron with a small tip, rosin core solder, small side cutters, small screwdriver, and the module can be built in about an hour. On a difficulty scale of 1 to 5, 5 being the most difficult, this is rated at 2 or 3.
