>> Hello Serge,

>> prominent landmark, hill, light pole tree in a property near you and then
>> set another way point on the GPS, now the further away the reference point

>>
>> While at the land mark in the GPS select 'navigate to way point' and
>> select
>> the one you created for your tower and you will have a true north angle
>> you
>> can then use some math to reverse it to be the azimuth from your tower to
>> the location.
>>
>> I now realize while writing this I could have walked back to my tower and
>> did the opposite and selected the navigate to way point and select the
>> remote point but hey that's too easy : -)
>>
>> Of course this does not help with elevation calibration but works a treat
>> the get the AZ rotator calibrated.
