1. Over Water and Overland
Midwest 10 GHz
Over Water and Overland

2. Many started
with FM Wideband

3. More Power and gain!
10mw
17db horn = 500mw ERP 2w
29db dish =
1 KW ERP

4. Challenges Output power Azimuth accuracy Narrow beamwidth
Frequency accuracy and stability
Attenuation by terrain or foliage
Where’s a guaranteed clear horizon?

6. One group fixed on the Keeweenaw Peninsula

7. Another group traveling along Minnesota’s “North Shore”

8. Up the shore Saturday, back down Sunday.
Bounce Shots

9. Evaporative Duct
Signals carry far with little attenuation when conditions are “just right”.
For VHF/UHF, that’s when subsidence and stable air yield stratification of temperature (and humidity)
For Microwaves over water, we found the Evaporative Duct
Navy noticed the Duct 3 GHz and up w/ radar

13. Above or below the duct?

14. Overland Clear horizon—even flat fields (soybeans good)
Know your bearings—either via good map work or “apps”
Mid-day lull
miles reliable often. More possible

21. Widespread Activity

22. Rainscatter! 600 miles! Sit at home warm and dry!
Ragchew on 10 GHz FM!
“Common volume”

25. Back to Superior 2012 August weekend of 10 GHz contest (Aug 18/19)
Enjoy the Northwoods AND microwaves
10 GHz, 24 GHz, 47 GHz + lower bands too
Lots of Q’s in several directions

26. Interested? Take the next step—let others know Help each other, Elmers
Reflectors: Microwave, NLRS, BC’ers
Tag along or better yet:
Loaner rigs!
10 GHz adventures await you!
