Re: Introducing the ULR DXing Chart-Index

Excellent point. I think keeping LW and MW separate is a good idea as the numbers for LW can be much higher.
6.56 for 7BU is a good effort, sadly they switched to FM a couple of years ago. This has had the advantage of helping me as it has opened up 558kHz for some DX from QLD and WA.
The really astronomical indexes come from low-powered Longwave aeronautical beacons (NDB's) received at ranges over 10,000 km across the equator. 362-WK in Whakatane, New Zealand (25 watts at 11,017 km from Manzanita, Oregon) results in a wacky index of 440.68, while 366-SF in Springfield, New Zealand (50 watts at 10,977 km from Manzanita, Oregon) results in a more modest 219.54.
