New features to be added:
1) support for WSPR TX that aren't in the hamlib list
2) support for switchable filters

  • some WSPR TX are not supported by the Hamlib library - for example stand alone WSPR TX based on the Arduino or RPi and the si5351 or similar chipset. These can still be controlled by WSPR Scheduler. Some of these require an external band or low pass filter to remove harmonics (as the si5351 output may not be sinusoidal). Each filter can be switched by an Arduino.

    Currently testing with an Ardiono based WSPR TX driving an AD9850 DDS

    Now able to control an Arduino based WSPR TX via an API. This uses an AD9850 DDS and NEO-6M GPS. Seems stable, but further testing required.
