Near Intersection of I-35 & I-90 Southern Mn. | I would try the receiver on the top of the extenstion. This is more prone to being "knocked" off my tree limbs etc. so I would put some type of tether on the unit so that it doesn't fall into the combine.
You are probably using WAAS PRN #122 which as you may know has been moved considerably and has been causing some problems.
Moving the GPS to the highest point may help, this would be my first step. If you are dropping back from DG to -G this is an indication of loss of the "Differential" (the WAAS correction system). |
