All:?

While monitoring 30M APRS, I noticed a discrepancy in the distance calculated by YAAC between myself and VK5RR. The range should be approximately 10,500 miles, but YAAC showed 1,700 miles. I checked APRS-FI to see if VK5RR's position might be off, but it appeared to be correct. YAAC did show the correct bearing which is 273 degrees.? ??

The distance for all other stations seems fine so not sure why the discrepancy for VK.?

Any ideas??
