·/Moon Noise value/s have been revised to reflect the latest findings. X and Ku bands have been incorporated. Data from Goldstone measurements confirms measurements from Peter G3LTF for 6, 9 13 and 23cm. Source reference provided in the Help file. The accuracy of the Beam fill factor for very large apertures is still to be resolved with ongoing investigation but for normal Amateur size dishes is adequate.
* addition of a /calendar date option/ enables review of measurements
taken at preceding or future dates. This option provides relative
Moon data (phase, path loss, Moon noise etc.) calculations for the
date in question.
* addition of a /Ground temperature slider/ to provide a means of
measuring more accurately the Ground to Cold sky ratio by adjusting
the temperature of the far field object to the temperature it will
most likely exhibit. Settings for depression angle and type of
reflective object (walls, trees, ground surfaces etc.) has been
covered in detail and is explained within the help file ‚Measurement
of Ground to Cold Sky ratio‘ by Peter Blair G3LTF. (a ‚must read‘).
The accuracy obtained from actual measurements have proven to be
EME Planner Ver 2.18
* Revised method of window calculations to provide user adjustable
minimum and maximum elevation windows for both Home and Dx Stations
in the Planner option. The values may all be stored for recall if
desired. It is now also possible to go down to minus 3 degrees if
Peter Blair G3LTF for his considerable work on Ground temperature (or Q Factor), Charlie Suckling G3WDG re date option, Rex Moncur VK7MO for his persistence in Moon temperature and Beam fill factor (ongoing) and Dimitry 4Z5CP and Steffen DD0VF for their suggestions regarding window calculation requirements.
