[Mark VandeWettering] was experimenting with a simple transmitting circuit and an Arduino. The circuit in the project was designed by [Steve Weber] to broadcast temperature and telemetry data using… ...

An Arduino and a few other choice pieces of circuitry. In particular, [hvde] removed much of the RF portion of the radio, leaving just the parts that dealt with the intermediate frequency at 7.8 MHz.

Because some hardware setup is required to build up a functioning radio, an Arduino can be used to supply the voltage and control the radio chip. The 3.3-V power can be taken from the Arduino’s ...
