Description
Tool to show current HF propagation prediction.
[INTRO]
Ham Solar is using code from Paul, N0NBH website. Its requires internet connection.
[HAP CHART]
Hourly Area Prediction (HAP) chart feature is also provided by this app. Its specifies the Maximum Usable Frequency (MUF) for HF communications between the base specified and any location on the map. The colors represent the MUF for communications between that location on the map and the base selected.
Thus, if communications are required to or from Minneapolis, a HAP chart for Minneapolis should be used. The other end of the circuit is then found on the HAP chart and the color at that location gives the MUF for that circuit.
HAP charts are charts based on current ionospheric conditions observed with ionosondes in the region of interest. This chart is only valid for the current hour due to the highly variable nature of the ionosphere.
It is also helpful to view HAP chart propagation from the perspective of distant locations. In this manner you can determine if they are able to reach the Midwest with a usable MUF.
If you love this app, please kindly to rate it and give donation to Paul. Just inform me via email if you find any problems.This app is fully designed by using MIT App Inventor 2.

This app used to work very well giving a map showing dx activity, but recently it appears the app lost it's webpage and redirects to a not found page. Was great whole it lasted. Other than that the band condx page is still working.
