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 ✰ / sorry, I'm astrophile and having all data
  at hand I couldn't help implementing these functions)

- beacon can be configured to display data in m, ft, °C, °F, km/h, mph, kn
