Two stations share coordinates but not towers (KVMR & KJPT)

This appears to be some strange technical situation. Both stations are on Banner Mt. in Nevada County. KVMR's coordinates are 39 14 47.00, 120 57 48.00 [NAD 27] (http://transition.fcc.gov/fcc-bin/fmq?list=0&facid=176615). However, KVMR has a tower location of 39 14 47.0, 120 57 52.0 [NAD 84] or 39 14 47.38, 120 57 48.20 [NAD 27].

Meanwhile, KJPT has coordinates are 39 14 47.00, 120 57 48.00 [NAD 27] (http://transition.fcc.gov/fcc-bin/fmq?list=0&facid=176615). These are the same as KVMR. KJPT's tower is at 39 14 46.6, 120 57 51.8 [NAD 84] or 39 14 46.98, 120 57 48.0.

Can anyone help me understand how two stations can have the same official coordinates and yet have towers that are a few hundred feet away from each other. Does this have something to do with rounding of coordinates? If so, it seems strange that the FCC reports coordinates to the 1/100s decimal but doesn't actually use them.

Thanks for your thoughts.
 
As a person who visits that site regularly I can tell you that there are indeed two separate towers (well, KVMR's is a steel monopole and KJPT's is a wooden telephone pole). I have a feeling it has to do with when the various locations were documented and the availability of accurate measurement tools at the time. I also suspect that the KJPT application, which was part of a big non-comm window, was one of many app's across the country for Immaculate Heart Radio. The people working on it said "we'll use Banner Mountain - find somebody there and use their coordinates" figuring they'd work out the details if the license was ever granted.

They wound up leasing space on the "Knox LaRue Pole" up there. Oh - and KVMR and KJPT aren't the only two with the same coordinates. K272DX (102.3, owned by Calvary Chapel) is also licensed to that location and located on the Knox LaRue Pole.

BTW - has anyone heard KJPT? They were testing a bit last summer and were granted Program Test Authority on July 31st. But so far I've heard nothing whenever I've checked. Weird.
