Etherkit debuts with open source QRSS transmitter kitEtherkit, a new amateur radio kit company devoted to open source hardware, has released its first product for sale.
OpenBeacon is an open source crystal-controlled QRPp beacon transmitter kit which can output a variety of slow-speed modes, including QRSS, DFCW, and Sequential Multi-tone Hellschreiber.
It is configured via USB port, so there are no jumpers to set and you can easily adjust all of the operating parameters via command line. Once configuration is complete, OpenBeacon may be removed from the PC and operate stand-alone, as the on-board microcontroller stores all settings.
