VOACAP not accurate]

[n4hnhradio-ai]

The VOACAP prediction at the lower left will show 40m and 80m as valid for EU contacts in the middle of the day. We cannot even reach from coast to coast in the US on 80m or 40m during the day.

A clear and concise description of what the bug is.

Click an area of the map that is an area where you know that 40m or 80m have no chance at propagation during the day.

Expected Behavior

40m and 80m should not show green for U.S. to EU, or even coast to coast in the U.S., during the daytime.

can you send a screenshot? is it the chart or the bar graph showing the issue?

I’ve been sending screenshots but the emails bounce back. It happens with chart and bars. Nowhere close. I think the antenna assignment is nice but I think that it is skewing the results. 73,de N4HNHDoug McAlexanderN4HNH Radio on YouTubeOn Apr 6, 2026, at 9:12 PM, accius ***@***.***> wrote:accius left a comment (accius/openhamclock#887) can you send a screenshot? is it the chart or the bar graph showing the issue? —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you authored the thread.Message ID: ***@***.***>
