AVR beacon project utilizes a new approach to RF signal generation using SQDDS method (making RF signals directly from the software, based on a pre-calculated periodic bit-sequence). It is mainly used by the hamradio operators to set up various radio beacons for different purposes, mostly for radio waves propagation discoveries. CW (continious waves, Morze code) is a main modulation mode. Other modes like PSK and FSK are planned to implement in the future releases. User can enter any ASCII text to send it to the air. Transmission rates and modes are configurable from the input text. AVR beacon can read an external digital instruments like (voltmeter, thermometer, axelerometer, anemometer, etc.) and send its data to the air. ...

Implementation of a amateur radio morse code/CW beacon controller for the embedded MCU card "hc908 daughtercard" by NJQRP (http://www.njqrp.org/hc908/index.html).

M4DSP is a QRP (low power) hamradio digital signal processing (DSP) tranceiver using a comprehensive yet powerfull Cortex-M4 MCU from STMicroelectronics. The main goals are: low cost, low power consumption, IPhone-like size & weight, QRP CW RX & TX, SSB/AM/FM RX-only, digital modes by demand, GUI with TFT + touchscreen, waterfall spectrum, CAT communication link via low-speed USB, pure SDR-like mode via high-speed USB, one or more hamradio bands (160-10 m), optional support for general coverage RX (0-30 MHz).
