PROBLEM SOLVED:
026 - Conversion error in Pressure calculation for SGP model.

V 1.7 (02/09/2018) ------------------------------------------------------------

NEW FEATURES:
025 - Precise pressure calculation for Rs41-SGP model.
      A new algo was introduced to calculate the pressure for the SGP model.
      For the Rs41-SG model (without pressure sensor) the reported pressure is currently only related to GPS altitude (work in progress)

024 - Antenna Rotor Handler
      Software can handle an AZ/EL antenna rotor in order to track Rs41 Radiosonde.
      Supported protocols are: 
      - Yaesu GS232a/GS232b
      - Window Registry (position provided by means of two windows registry keys to support customizations)
      in addition to automatic tracking mode, it's also possible to set antenna position by means of:
      - preset values 
      - manual set of Az/El Values.

023 - RS41 Telemetry export
      The software is now able to save telemetry in csv format.
      Saved fields (when availables) are: 
         Time,Latitude,Longitude,Altitude,Sats used,
         Wind Speed (m/s),Wind Dir (deg),Vertical Speed (m/s),
         Temperature(deg),Pressure (Hpa),Humidity (%),Dew point (deg)

022 - Improvement of "Load RS41 RAW data file" function
      A control panel is added in order to regulate the processing speed of the RAW file.
      Following speeds are introduced: Max, 8x, 4x, 1x, 0.5x, Stop.
      Speed Labels can be clicked in order to quick set the related value.
      File processing can be terminated pressing the related button in control panel.
 
021 - Maximum wind speed received from a radiosonde is now reported in status bar.
      This value is referenced with related altitude and wind direction.

PROBLEM SOLVED:
020 - Software stuck when received preamble data is located in a particular data buffer location.
 
V 1.6 (23/07/2018) ------------------------------------------------------------
NEW FEATURES:
019 - Software updates check (at startup and on demand).
      The software now it's able to verify if a new software version is available.
      Automatic check at startup can be enabled/disabled into settings section.
      Manual check can be performed using the "check for update" button located in "About" window.

018 - Detection of ozone sensor unit.
      Software is now able to detect if an ozone sensor unit is connected to Rs41 radiosonde.
      Information is reported in signal processing section of the main window and it's reported as "Ozone".
      When "Led" il blinking the ozone sensor is present.

017 - Ozone sensor telemetries.
      All information related to the ozone sensor telemetries (if present) are now reported. 
      The following information are available:
      - Instrument type
      - Instrument #
      - Ozone pump temperature
      - Ozone pump current
      - Ozone Current
      - Internal Battery voltage
      - External Voltage
      - Serial number
      - Software version
      - Diagnostic word

016 - Maximum altitude received from a radiosonde is now reported in status bar.
      In case of good signal received (no data loss) this value is is the baloon burst altitude.

015 - Introduction of PTU parameters (Pressure, Humidity, dew point)
      Due to lack of information related to PTUs, these parameters have to be considered as an estimation.
      Please see "Telemetries accuracy" chapter of user manual.

V 1.5 (09/06/2018) ------------------------------------------------------------

NEW FEATURES:
014 - The measurement units of Vertical speed and wind speed can be choosen between: 
       - meters per second, 
       - kilometers per hour,
       - knots
013 - Shortcut for google-maps in browser. This command  show the radiosonde latest position using google map on your favorite browser.
012 - Radiosonde track can be saved in kml format (and loaded in google earth software for 3D evaluations).
011 - Support to kml ghost-track. Software is able to load a GPS track file in kml format.
      This feature was introduced to allow real time comparison between the current radiosonde track
      and the forecast track provided by site http://alerteselectroniques.fr
      Of course any "well formatted" kml file can be loaded.
 
010 - Bearing resolution increased (tenths added) 
009 - Bearing and Elevation position swapped

008 - Frequency reported in Radio I/F box was wrongly cleared once new SondeId was found.

V 1.4 (30/05/2018) ------------------------------------------------------------

PROBLEMS SOLVED:
007 - The problem of time format (invalid date 06/01/1980) (the same reported in point 001) affected the software in two different brach of code. 
      Now also the second occurrence is cured.

V 1.3 (28/05/2018) ------------------------------------------------------------

NEW FEATURES:
006 - Frequency range allowed in radio control extended to 400 - 407 MHz 

V 1.2 (26/05/2018) ------------------------------------------------------------

NEW FEATURES:

      bearing, range and Slant range of the received sonde.

004 - Home location is now shown on map using a new marker symbol 
      (settings -> Maps to provide Home coordinates).

003 - New working session automatically starts when a new sonde is received 
      (This allow to handle several RS41s on the same working session)  

PROBLEMS SOLVED:
002 - The decoding function doesn't work as expected When Radio control is 
      activated but SDRSharp plugin is not running.
      Solution:Radio Control Engine reengineered.
