Some GPS receivers will deliver the Maidenhead grid square directly. http://www.n7cfo.com/vhf/gps/~gps.htm I just took my portable, WAAS enabled, aviation GPS to the back yard and let it average for a couple of minutes. Since then I discovered why I kept getting different results pre-GPS (long boring story about map accuracies); turns out the dividing line runs down the sidewalk across the street. Chuckle. We're close to that problem at the local club station (K6BJ): http://802.11junk.com/jeffl/pics/drivel/slides/grid-cm8x.html I had to post this map because operators were constantly calculating the wrong grid square. Nearby, is the local intersection of the lat-long lines. http://confluence.org http://confluence.org/confluence.php?lat=37&lon=-122 Notice the wide variations in photos by people thinking they've found the correct location. The problem is that the real intersection is located on a poison oak infested steep hillside. We posted a DGPS located marker, but people keep stealing it. As it turns out, my house is in the very SW corner of DM14fco7, with the front in DM14fco7ae and the back in DM14fco7be. mandatory antenna content If you go to http://no.nonsense.ee/qthmap/ and enter DM14fco7be the white dot in the middle of the back yard is the box covering an SGC autotuner for the 33 foot vertical. |
