Description
[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.

Simple app that displays the propagation chart. Does exactly what I need it to do.

This is a wonderful app to know when shortwave propagation is high, so I can listen to Nagoya, Japan from Saskatchewan, Canada. I can also listen to over the horizon radar, the ever dwindling amateur radio operators, ships at sea, and military shortwave operations. This is the most concise app for the size.

A "must have" for hams! It's a no frills' app, just straightforward information you need to know about solar conditions. The same graphic is available online at various sights, but having the app is so much easier. I use it to determine whether I am going to jump on the radio and operate, or if it is better to go do something else as my free time is limited.

I like to see hams on map but nowdays it can't connect to map
★★★★★Jack Hengert· Feb 5, 2021
Very helpful to know what's going on with propagation each day.

Thank you for your quick response to my post. I truly appreciate your time and interest. To detail my issues; I have had your HAM SOLAR app for quite a while and really like it. Recently the app just stopped working. By stopped working I mean it would not load beyond the initial splash screen showing two globes, the refresh and donate buttons. After rebooting my phone several times with no joy, I deleted the app and reinstalled it with the same results. I also tried to reconnect from a different location on the other side of town with the same (or lack of) results. Additionally, While reloading the HAM SOLAR app, I saw another of your apps, HAM CONTEST, which I thought was a great idea. I downloaded the app and found the exact same issues noted above. As you might imagine, this has been very frustrating when I also have the HF PROPAGATION app loaded on my phone, and it is, and has been working FLAWLESSLY for months. Thanks again for your time and the quick response '73 Steve Sutker K4LEG
