Do your microwave folks know of any good RF absorber material for cheap? We've been thinking here of fabbing our own due to the crazy prices of commercial material. Also, do they know of any antennas that are cheap and come with not just gain, but also radiation splatter shielding? ie: keep the radiation focused only where it's supposed to go, with massive F/B and F/Side ratios? These are the present problems plaguing us here in the Puget Sound. Perhaps your experts can help. As far as the 72km link goes, as long as you've got the height, you can do it no problem. The curvature of the earth becomes a significant issue at those distances though. --Bart On 08/12/2013 10:03 AM, Kiernan Burr wrote:
Hahaha yea, lots of how to, I am not an IP guru, we have some very talented microwave people in the area, so path analysis is covered.
To start we have issues with our ISP, and that we can upload at rates of no more than 750kb/s. we have echo/IRLp at our main repeater site as well as a complete D-Star stack. So as you can see we easily max out our bandwidth.
At this time there are a couple of us that would like to see, to start, our three in city sites. Call signs ve6hm, ve6uv, and ve6jn. My personal pie in the sky hope would be to tie in our ve6plp site south of the city at pigeon lake(about 72km). Lofty goals I know. To push that kind of distance I figure we will probably have to use 900MHz tho.
Immediate use would be to allow a D(free)-Star repeater to extend coverage south along hwy 2. In the future who knows what we would be able to do.

Greetings, fellow Canuck.
What part(s) of northern AB are you thinking of covering? The devices are low power enough that they could run on solar.
Did you have some specific questions in mind? There's a lot of material on the website, but not any simple how-to-do-X pages. I assume you'd probably have questions around that.

Hi all,
Just subscribed to this list. A couple of locals here in Northern Alberta have been mulling around the idea of building an ametur radio based microwave IP network. Unfortunately we do not have the advantage of terrain here like you guys do, we do have access to some decent sites. Our vision for a system out here is two fold. 1 it would allow us to expand digital voice networks(D-Star, possibly DMR as there is some interest locally. 2 it would give us a network independent of public infrastructure(asides from power).
Thanks for your guys time.
