#### Statistics by band?

n7px@...

My son and I have been using AClog the past month to document the 800+ FT8 contacts we've made for a Science Fair project he's doing on HF propagation.

We're trying to determine by band the average DX contact distance.  I see the overall figure in "statistics" but not how to do it by band short of removing all the other contacts from the log!

We have exported (copied and imported) all the contacts into an Excel spreadsheet and was thinking I could use a function in Excel to calculate distance between our QTH and the country, but haven't found a way to do that.

Any suggestions welcome!  Thanks!

Checkout these 2 web pages.  As long as you logged the grid squares you should be good.

I have used Excel to calculate latitude and longitude from grid squares. It's time-consuming to set up but it works well and can take the grid squares from the WSJT log and convert them to latitude/longitude pairs. Once you have the latitude and longitudes of your QTH and the QTH of the DX station, you can use the Haversine equation to calculate the distance between them. You would just add this function to the spreadsheet which calculates the lat/long pairs from the grid square. There's a good article on implementing the Haversine equation in Excel at:

Can you use the “Call Search” function in QRZ? When you have a call loaded, touch the map icon at lower left, and the program will render both bearing and distance between your station and the station you have contacted. This procedure would have to be repeated for each of the 800+ contacts you want to include in the study. Then you would need a way to transfer the data to the spreadsheet (manually). 🤷‍♂️
I’m curious to know if this comes even close to a viable solution.🤷‍♂️
[BTW, you are 2340 miles @ 90 degrees from my QTH] You are also 3 hours deeper into the night than PDT.

It also occurs to me that some stations may not be registered with QRZ.🤷‍♂️🤷‍♂️
