Would it be possible at some point to add the current MUF to the Solar tab?

It’s possible to use ViewProp to visualize the current MUF, in two ways.

First, you can use the map for a true path-oriented approach, by finding the highest frequency spots in your chosen area of interest (enabling lines on the map may make this a bit easier).

Or you can configure bar charts to let you see the highest frequency bands that are active on an “averaged” basis. The default for the charts is to include all spots globally, but you can easily narrow down the selected location by a bunch of different filter criteria. Bar charts have the advantage of letting you see the history over the last 24 hours, where the map is only the last hour.

Unfortunately, the catch is that someone has to be transmitting from your area of interest–and on the right frequencies–for this to fully work. The plus side is that it’s much more accurate than tools based on long-term averages, such as VOACAP.

Anyway to have the Map keep its settings every time (DX Atlas)?

Some yes, some no.

If you go to Settings > Map, you can change a number of initial map settings, including the default position (see the screenshot below).

Those settings are “live,” in the sense that DxAtlas will respond immediately to any changes. They are also uni-directional, in that changes you make from the DxAtlas UI are not reflected there.

Those settings are persistent, provided you either exit ViewProp cleanly (File > Exit), or if you explicitly save them (File > Save settings). If you kill VP or if your PC crashes before you do one of those things, the changes will be lost (as with all other settings).

Other map-related settings, such as Lines and Slices, as well as Bands, Filters and Antennas, are persistent in a similar way.

However, the actual content on the map is not persistent. The specific spots will reset whenever VP is restarted, along with the contents of the Path Grid and the Bar Charts.
