It seems odd that interference between the 2 with a good spread would have 
problems, we have a lot of 802.11 traffic in our small 2 wireless ISP town. 
And are using 1,6,11 at our site even without a real problem, I assume since 
you know how to use an SA that you know what you are doing ;) but I was 
wondering if you need to move your antenna's farther apart (4ft or more), and 
have you tried polarization? Put one vertical and one horizontal?

I'm interested in what you turn up, I've actually been thinking about doing a 
link like that here. We have one 4mi PtP link that doesn't quite clear the 
fresnel zone all the way and with the loss of tree attenuation can only move 
5.5 over it and I'd love to setup another link to get the other 5.5.

You wouldn't happen to work for a WISP yourself?
