[time-nuts] Morion MV89A position

[EWKehren at aol.com]

This was in the 70's and I only looked at it for a month in those days also 
 limited equipment and I used a Tracor 599 for frequency tracking.
Location was University Park in Dallas which is elevated so there was no  
water present. Left 20 years ago so I have no way of conducting any tests. 
Could  repeat it but I am looking at an other relocation.

Over what time period?  Dry  ground or wet?  How deep is your water table?  
 ...

Temperature in the ground is a skin-depth problem.  Lower  frequencies will 
go 
deeper.

Next time somebody digs a hole like  that, it would be fun to put a string 
of 
thermometers in  it.
