Locked Willmar HHS site coverage conclusions


 

The previous map with a roughly 30 mile radius circle from Willmar gives a pretty good representation of a modest station's expectation of Winlink service.
?
My test rig is a Toyota Corolla with a Yaesu FTM-200 radio to a mag mount dual band antenna on the trunk with about 3 dBi gain.
I used a laptop computer with a Digirig interface.
I ran 25 watts of power and always faced the back of my car towards Willmar.
?
I tried to think like a good Ham when choosing my parking spot.
Publicly accessible and out in the open if possible.
Avoid nearby buildings between you and the other end.
?
In an emergency situation not all of this may be possible. Then you do the best you can.
?
Home stations with a reasonable outdoor 2m antenna can probably add 10 - 20 miles to the circle, depending on terrain.
?
In conclusion, the coverage of this system is all I had dared hope for and more. :)

He's an estimated coverage map that may help. 25 watts from top of the tower to a mobile station with 6 ft antenna

Received this Winlink email from Leon KF0OUA today.?
Google says that park was 44 miles away as the crow flies.
The location GPS coordinates are for his QTH.
