Version 2.6

Release Date: November 2021

Free Features (all users)

New DEM option to take higher resolution gridded terrain altitude data from user supplied NASA SRTM files in HGT format.
New DEM option to take altitude data from a user supplied GIS Contours file (e.g. KML or OSM format) containing detailed terrain contours.
New Tools Menu option to directly download the latest spectra_rrl.zip file from ACMA website.
After using the AMG button to enter site location in AMG coordinates, the program now queries user whether to use DEM altitude or manual entry.
Data Map Grid tab now includes option to map the magnetic declination per latest WMM-2020.
Default output file names for Path Profile and PFD Calculations now also include the DEM type.
Path Profile tab now includes option to enter altitude for each site, as well as a Check DEM button for each.
Path Profile tab now includes a button that allows user to swap the Transmit and Receive ends of the path.

Pro Features (registered users)

All Climate data and propagation/interference calculations from ITU-R Recommendations were reviewed and updated with the latest versions where applicable.
Add menus to Path Profile window.
Add option on Path Profile window to save path profile to GIS map file.
Add View options to Path Profile window to allow user to change default colours, fonts, and plot title.
Output CSV file for PFD Single Site calculation now includes columns for both True and Magnetic azimuth bearings of each interference signal.

Bug Fixes & Other Refinements

All web access improved to use secure https:.
Updated code libraries to latest versions.
Various minor improvements to coding and window layout.
Windows XP no longer supported by this program.

Version 2.5

Release Date: June 2020

Free Features (all users)

Updated the built-in ITUR DEM topographic database to latest P.1511-2 (2019), with 1/12° (5 minutes) resolution.
Conversions from Extraction file to GIS map data file (maplist, KML, GeoJSON, etc) will now include altitudes, if they are available in the Extraction file.
When selecting a location from user file, when no altitude data is included, program will warn the user instead of just automatically using altitude from DEM. Gives user the chance to CheckDEM or enter an alternate value manually.
Path Profile tab now shows boxes for optional site names and includes these names on output files and on path profile plot.

Pro Features (registered users)

All Climate data and propagation/interference calculations from ITU-R Recommendations were reviewed and updated with the latest versions where applicable.

Bug Fixes & Other Refinements

Fixed bug where the preferred size of the Path Profile window was forgotten if the window was closed while maximized.
Fixed bug where coordinates from a user file in AMG format may not be correctly converted to WGS84 latitude/longitude values.
Additional checking in case DEM or RRL database files have been moved or deleted since last run.
Comment lines at end of map grid (*.warray) files marked with "//".
Various minor improvements to coding and layout.

Version 2.4

Release Date: June 2019

Free Features (all users)

Added columns to end of each line in extraction CSV file to hold information decoded from emission code, including emission bandwidth.

Bug Fixes & Other Refinements

Fixed bug where longitude<90E could be mistaken as an Aust-Wide licence (e.g. Davis station at longitude 77.96E).
Allows more decimal places to display on Path Profile window, when applicable.
Uses more decimal places when saving settings for next session, to avoid issues of lost data due to rounding.
When selecting a location from file, user may now double-click on the location name in the list.
Improved error detection & reporting.
Various minor improvements to coding and layout.

Version 2.3

Release Date: April 2018

Free Features (all users)

Added "Call Sign" column to end of each line in extraction CSV file.
Added search options on Extraction tab to filter extractions on Site State, Licence Service Type, and/or Access Area for wide area licences.
Added options to enter desired coordinates in AMG format.
GIS map data output conversion now includes GeoJSON format option.
Added item in Tools Menu to open the ACMA RRL download page in the default browser.
Removed the "Annual Rain Probability" option from the Data Map Grid tab, as this value is no longer calculated as part of the Rain Rate calculation.
Added Surface Refractivity and Delta Refractivity options to the Data Map Grid tab, these values are used in the PFD Interference and Path Loss calculations.

Pro Features (registered users)

All Climate data and calculations from ITU-R Recommendations were reviewed and updated with the latest versions where applicable.
Added "Decode Emission" item in Tools Menu to allow user to enter an ITU-R Emission Code and decipher what it means.
In addition to the actual Average Path Loss which takes into account obstructions and atmospheric effects, the Path Profile dialog now also displays the basic Free Space Loss between the two antennas.

Bug Fixes & Other Refinements

Fixed bug where "area_id" and "access_area_name" columns were incorrectly filled in extraction CSV file.
Fixed extraction to GIS map file conversion to properly cope with sites in the Antarctic.
Improved progress display when extracting or calculating, and preserve partial extraction file if user clicks Cancel.
Improvements to the installer, especially when installing in multi-user environments.
User preferences are now stored in the user's AppData\Roaming\RadcomSearch folder rather than windows registry.
All CSV output files use UTF-8 encoding, and include the UTF-8 byte order mark (BOM) so they will be loaded correctly in Excel.
Minor changes in layout and text box size to improve the appearance of some windows, depending upon the user's currently selected Windows theme.
Improved file checking and error reporting.

Version 2.2

Release Date: November 2016

Improvements to error handling and reporting.
Improved updating of progress dialog when doing large extractions.
Added "Check for Updates" option in Help menu.
Minor improvements to file formatting.

Version 2.1

Release Date: September 2016
