<br>
I used the Scadacore RF Line of Sight path modeling <br>
(<a class="moz-txt-link-freetext" href="http://www.scadacore.com/field-tools/rf-path/rf-line-of-sight/">http://www.scadacore.com/field-tools/rf-path/rf-line-of-sight/</a>)<br>
This app has to be run on device that has google earth app
installed, like an iPad.<br>
<br>
Using these parameters:<br>
<br>
Haystack Lat: 47.808024<br>
Lot: -121.727227<br>
Height: 3 m<br>
<br>
My QTH Lat: 47.722862<br>
Lot: -121.925666<br>
Height: 10 m<br>
<br>
<br>
<br>
From the looks of the plot, I have obstructed line of sight at
19.41 km. So unlikely Haystack will work. Will check out the
other sites...<br>

I completely missed the lat/lot at the top of the
pictures page...<br>
<br>
Do you know the MSL (height of the haystack antenna).
Seems I have missed that too...<br>
<br>
Will be happy to share my method for path modeling
once I get it up and running... <br>
<br>
Thanks!<br>

Can someone please send me the exact
