Some background for the group HamWan, is a data network built by amateurs in the pacific NW. Primarily in use in and around the Puget Sound area of Washington State. The bandplan they list covers from 5.815 up thru 5.925 for "client access" and they use the non amateur channels for the backhaul links. AREDN is another data network in use, doing essentially the same thing. A snippit of the channel list is below.
From what I can tell looking at the FCC chart, this letter references the spectrum from 5.850-5.925 as it is the only listed block of 75 Mhz as referenced in the note. An attachment is included here with that data. If that is the case, then they are looking at the only non-shared channels we have available for these systems.
As I just bought a pair of Microtic dishes for use in our AREDN network, I will be watching this close as well. :) Mark, HDX [image: image.png] On Wed, Nov 20, 2019 at 4:07 PM Michael Ritz <w7vo@comcast.net> wrote:
This, at first glance, seems to be a direct assault on our 5.9 GHz allocations. That said, I'm not aware of exactly what frequencies HamWAN uses, and how this will affect that emerging technology amateur radio program. Anybody know anything about this?

Mike:
Please pass this along to the spectrum defense folks at HQ:

The use of this spectrum in Western Washington is significant, and our EOC-to-EOC amateur radio data infrastructure in that band is growing rapidly.
Thanks, Steve
