DRM-Log Plotter, Version 19.0 (8th January 2016, build 19.0.0)
A problem with S-Meter input related to the -dBm part has been resolved in the latest version. This version now supports plotting of S-Meter levels which were logged with WinRadio G33DDC or RFSPACE-IQ. In order to plot these curves a File Converter (S-MeterFileConverter.exe) is needed as the file formats from these two receivers are different.

The zip package includes the S-MeterFileConverter.exe.

Additions to the previous version of the DRM-Log Plotter (Ver. 14.06), new from Version 15.05 (17th October 2013)
In this version there were some new features in "Set-Up". Look for "Default Audio Plot Thickness" and check the "Always Plot Audio Thin", if you want to plot Audio with the thinnest line as default. It is possible to switch to thick, but the thickness in this state is "2", not "3" as in the Ver. 14.06.

The Doppler curve has been changed to a logarithmic scale instead of the linear scale. This allows for the plotting of higher Doppler values than before.

The "zero" line is 0.1 Hz; that is the lowest value Dream software records. The 1 Hz falls on the dot-dashed grid line and so does 10 Hz (in the second decade, though there is no "10" in the plot to mark it). The scale itself ends at 5 Hz. There are some additional options in Set-Up to limit the Doppler scale. There is also an Auto-scale checkbox there. If checked, each log sets the Doppler maximum according to the Doppler value read from the log.

Important change in Ver.15.05 over Ver.15: An error in changing My Locations fixed.

Notes on downloading the DRMTRANSMITTERSITES.TXT:
When you download the DRM-TX list from the DRM-Log Plotter (TX Sites  --- >  Update) you will be prompted to proceed or quit. If you decide to proceed, the DRM-Log Plotter will download the latest TX Sites file from the web, compare it to your local TX Sites file and add the entries it could not find on your computer. The entries you might have added yourself will be left as they are. No TX Sites will be deleted.
