[Lowfer] Calculating reception distance accurately

[PAUL DAULTON]

Another site I use seems to be easy and accurate.
www.indo.com/distance
I looked up Distance from Friendsville Tn to Jacksonville Ar. Site shows
456 miles, lists you in Blount Co. Is that correct.

Hey Everyone:  
 
I'm hoping that many operators will find this information useful. I have
 found that trying to use even 6 digit grid square locaters, that the
 airmiles can be off considerably. The ARRL website shows the typical 4
 digit grid square to cover from 70 to 100 miles, and the locaters measure
 from center to center of the Grid Square. I have found internet based
 services that can pinpoint ANY !! geographical location. They are very
 simple to use. #1: go to:  
http://mapper.acme.com/  
On this site you can type in any physical address, and it will pull it up
 on a map, and give the Lat. / Long. down to the millisecond. After you
 have this information in hand; then #2; go to:  
http://www.waypoint.org/gps1-calc.html  
On this site, just type in your QTH coordinates in one field, and the
 other QTH coordinates in the other field. Click " Compute " and it will
 give you the GPS distance in Nautical miles, as well as bearing headings.
 I have used the Maidenhead Grid Square calculator, using 6 digits on each
 side, and when compared to the system I use now, I have saw it to be in
 error by 20 to 30 miles easily. Give it a try, and see how it works. Look
 me up on QRZ; - KU4XR, get my address, use the mapper to find my
 coordinates, do the same for your QTH, and then go to the Waypoint
 calculator, type in the info and see the results. Then try the Grid
 Square  
method; I'm in - EM75xr - , then you can see how close they match.  
73 for now, and I hope you find this information of use.
