Hi I have had two "spikes" showing on my polar diagram one to the west of my location and the other directly north. These appear to be from aircraft outside the maximum range rings but not excessivly so. I am content the signals were generated by aircraft rather than some of the obvious spurious spikes I have seen.
Anyhow my query is where did the Northern "spike" go? It no longer appears on the polar diagram, the radarbox has been running 24/7, with no change in the map selected, so I'm at a loss how the polar diagram changed? The western spike remains and the rest of the diagram seems the same but no Northern spike!!
I am interested as this is the second time it has disappeared, any thoughts?
John
