This release - for all propagation prediction engines, limits the frequency range to 2 Mhz to 30 Mhz - for all propagation prediction engines, assumes the DX station employs a yagi for frequencies above 12 mHz - makes the "Required SNR" (signal-to-noise ratio) a user-specified parameter; it was previously fixed at 30 * makes it possible to specify the "Required SNR" by selecting a mode * includes the Required SNR in the information displayed above a forecast - downloads the smoothed sunspot number on startup, or on demand, and when available use this to drive forecasts in preference to current solar flux (SFI) - downloads the current solar flux and geomagnetic K-index on demand - makes all data source URLs modifiable by the user - can display shortpath and longpath distance in miles or kilometers - when displaying results, increases the accuracy of Y-axis labels to .1 MHz - provides the option to generate forecasts using VOACAP's methods 20 and 30 to forecast openings based on the probability of a "required signal to noise ratio (SNR)" being achieved * depicts band openings based on the predicted percentage of days in the month that the required SNR will be achieved (referred to as the "probability" of an opening) * displays the SNR, probability, and propagation mode ("number of hops") when the mouse cursor hovers over a predicted opening - provides a "Prediction Path" option that allows forecasting propagation to the DX station, or from the DX station * Provides the ability to specify the DX station's power output * Provides the ability to specify the DX station's noise level * indicates "to" or "from" in the information displayed above a forecast - accepts a command to provide a 24 hour short path and long path SNR and probability forecast for signals from a specified location on a specified frequency and mode, assuming the signals were transmitted with 100 watts and a 3 degree takeoff angle with a dipole (below 12 MHz) or a 3-element Yagi (above 12 MHz) - provides a "Track DXView Loc" option that when disabled prevents the "DX Station" panel's Lat, Lon, and Grid Square items from tracking DXView's "selected location" (tnx to Andy K3WYC)) - with "use multiple monitors" enabled, relocates to the primary monitor any window that isn't being displayed on a monitor - works around a Microsoft OS version reporting defect so that Windows 10 is properly reported in errorlog.txt file startup headers - updates the Configuration.htm, Operation.htm, and Prerequisites.htm documentation files Special thanks go to Nuno CT2IRY and Dave N2DPF for their many contributions to this new version of PropView, which included assessing the 20 iterations of PropView required to provide the new functionality describe above. Notes: 1. Update your firewall and anti-malware applications to consider this new version of PropView to be "safe" 2. If this upgrade doesn't work correctly, see the "After an Upgrade" section of 3. After upgrading, to revert to the previous version of PropView, see 4. To update the Solar Flux Index (SFI), Sunspot Number (SSN), or Geomagnetic K-index parameters, click the U button to the right of the parameter on the Main window's Parameters tab 5. SpotCollector 7.3.8 can be configured to request 24 hour short path and long path SNR and probability forecasts for Needed or for all Spot Database Entries 6. If PropView is directed by DXView or SpotCollector to display a propagation forecast with the new "Track DXView Loc" option disabled, the "DX Station" location will be updated to reflect the location for which the forecast was generated PropView 1.8.7 is available via the DXLab Launcher and via 73, Dave, AA6YQ
