Fw: [SBMS] KD7DTS plans to operate 10.3681GHz on Mt. Lawlor soon today using 447MHz W6TRW Repeater for liaison SOTA operation

The video shows a typical microwave operation. One minor technical error relates to polarization. They are using horizontal polarization, not vertical. In rectangular waveguides, the E field goes parallel to the short side.? The long side needs to be at least 1/2 wavelength.?? In the US, most hams use horizontal polarization.?? In Japan, vertical polarization is the norm.? So the 10G module for the IC-905 needs to be mounted differently from the factory drawing. Locally, favorite spots to operate include Mt. Diablo, Mt. Vaca, Loma Prieta and Mt. Umunhum.? None of these are easy hikes! ----- Forwarded Message ----- From: Michael Aust via groups.io <ava622@...> To: "[email protected]" <[email protected]> Sent: Thursday, February 13, 2025 at 01:49:06 PM PST Subject: Re: [SBMS] KD7DTS plans to operate 10.3681GHz on Mt.
