DRM-Log Plotter, Version 23.2 (5th September 2020, build 23.2.12)

The plotting of xHE-AAC Audio has been improved so that the Frames are presented to scale. Unfortunately there is little or no information on how the Frame size is constructed as the Frames are dynamic, not sized 750 or 1500 like the HE-AAC logs. Any additional information on the xHE-AAC structure would be appreciated.

The download file consists of the programme app only.

The zip file only contains the DRM-Log Plotter Version 23.2.12

DRM-Log Plotter, Version 23.2 (21st August 2020, build 23.2.4)

In the version 23.2 of the DRM-Log Plotter the Maidenhead Grid Locator can be written to "My Locations" in the DRM-Log Plotter. Goto SetUp / Receiver Coordinates / Change which opens the My Locations window. Write the Maidenhead Grid Square Locator in the "Add Location" field. The locator should be of the format "AB12cd". Press the "Convert" button and the Latitude / Longitude coordinates will be added automatically. This way you will get the actual distance and azimuth to the transmitter site.

Write the Maidenhead Locator and press Convert

  • Added the plotting of xHE-AAC logs, smooth and rough plots
  • Implemented a slimmed screenshot
