<p class="MsoNormal">I have a TAPR magnetometer in the ground (sitting at 24” deep).
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have tested for RF exposure as follows:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">80 M dipole, about 20’ away and 15’ elevation, 1500 W on 80M<o:p></o:p></p>
<p class="MsoNormal">30 M vertical, about 60’ away 200W (legal limit) on 30M<o:p></o:p></p>
<p class="MsoNormal">40 M double bazooka about 50’ away and at 30’ elevation, 1500 W on 40M<o:p></o:p></p>
<p class="MsoNormal">DX Engineering hexbeam, on 50’ tower, base of which is 70’ away, 1500 W on 20M, 17M, 15M, 12M, 10M<o:p></o:p></p>
<p class="MsoNormal">4-element 6 meter beam on 50’ tower which is about 70’ away, 500 W on 6 M<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">There was no discernable effect on magnetometer readings from any of these tests, which were a carrier for 10 seconds at the noted power level.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If anyone has ideas for additional tests, please advise; based on the above, my impression is that the current magnetometer should produce good results when in the yard of typical ham installation.<o:p></o:p></p>
