<br>
Looks like I had entered the wrong coordinates. Thanks for
running the path model.<br>
<br>
I have been working with Ed Morin (WB7UBD). He got me
straightened out. The modeling tool I was using was poor
substitute to Radio Mobile Online. I created an account and
since then have been getting consistent results.<br>
<br>
Yes, I know the trees will be an issue. My QTH is heavily
forested. I do not have a tower, so will just have to see what
results I get...<br>
<br>
Thanks for your help!<br>

<div>This is with Radio Mobile. The link is only 17.57km, so
I'm not sure why you get a reported obstruction at 19.41km.
One of us must be punching the coordinates in wrong.</div>

<div>On Google Earth the trees look pretty tall. Trees are
pretty good attenuators at 5.9 GHz, so you'll need clear line
of sight for it to work.</div>

I used the Scadacore RF Line of Sight path modeling <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

<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>
