A PowerShell script kit to run nightly to calibrate RBN skimmers.
Calibrates up to two instances of CW Skimmer Server and RTTY Skimmer Server each plus one instance of CWSL_DIGI based on skew data published nightly on sm7iun.se
Since the calibration adjustment is proportional, the script should be run no more than once per day and preferrably around 00:20 UTC, shortly after the content of the web page with skew information has been updated.
dailycalibration.bat is intended to run nightly using Windows Task Scheduler and also creates a log file.
When creating the task in Windows Task Scheduler, check the box "Synchronize across time zones" to make the time UTC if your computer is not already set to use UTC time.
Another suggestion is to set "active hours" in Windows Update to include the hour between midnight and 1am UTC to avoid spontaneous restarts from interfering with the update.
Depending on your PC's policy settings, you may need to run the commands in setexecutionpolicy.txt in a
PowerShell window as administrator to allow execution of the script files,
including dailycalibration.bat by Windows Task Scheduler.
testrun.bat and testrunv.bat (verbose) are test scripts that runs without updating any files.
