Over Water and Overland Midwest 10 GHz Over Water and Overland

Many started with FM Wideband

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

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

One group fixed on the Keeweenaw Peninsula

Another group traveling along Minnesota’s “North Shore”

Up the shore Saturday, back down Sunday. Bounce Shots

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

Above or below the duct?

Overland Clear horizon—even flat fields (soybeans good) Know your bearings—either via good map work or “apps” Mid-day lull 100-150 miles reliable. 200 often. More possible

Widespread Activity

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

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

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!
