I noticed the other day that the map was showing a spot for me on 30m, which was a surprise as I am only transmitting on 40m! I thought "Weird - is someone picking up a spurious signal of mine or something like that?" so I checked the data from the database query and found no such spot in the same time period. So I conclude that there must be some kind of error in the map or the query behind the map.

This is not the first time this has happened. I have noticed something like it several times in the past few months.

Is anyone else experiencing this sort of error? Probably only Gary W1GJM can actually address the issue.
