WSPR-beacon V2 / 200mW / 160-10m / based on Arduino™ & AD9850
Some characteristics of WSPR-beacon 2.x:
- as before all code is open source and well commented
- as before supports SWR calculation and PA protection
- as before many parameter are user-defined (timezone, bands, duty cycle, fixed or random frequency selection, ...)
- the parameter "band-selection" and "duty-cycle" that might be subject to frequent changes can now be accessed interactively using a PC and do not require updating the beacon software
- it uses a remote GPS-controlled beacon to acquire QTH-locator and date/time
- data is being cyclically broadcast by the GPS beacon on 433 MHz ISM band and may be used by other devices (e.g. ham shack clocks)
- existing beacon hardware can be reused (simply hook-up the ISM receiver to the port the DCF77 unit was connected to, which is D2)
- additional outputs of the remote unit that can be displayed are current position, speed, altitude, outside temperature, current altitude/azimuth of Sun and Moon, Sun's and Moon's set- and rise-times as well as the moons phase (turning your beacon into a pocket planetarium ✰)
- beacon can be configured to display data in m, ft, °C, °F, km/h, mph, kn
