Hilltopper 20

The Hilltopper 20 is a no-frills 20 meter QRP transceiver kit. It is tunable across the band, has a built-in keyer, and its RF power output is approximately 5 watts, as claimed.

Of particular interest, the microcontroller is an ATmega328P, same as in Arduino Uno. Source code for the control program is open-source and available for download from Four State QRP Group.

Thus the kit builder is able to modify or add to the Hilltopper’s default feature set. More at: http://lloydm.net/Demos/Hilltopper-20.html.
