Shouldn't the 10 MHz Plan be bumped down by 5 MHz(or some other amount) to allow 5MHz as a Guard at the top of the Ham Band Plan? I don't know what is on the other side of 5.925GHz; but I'd assume it could be an issue to us. Has that been discussed before and I just missed it? Maybe just 1 or 2 MHz would be sufficient? We are starting to move forward with the Portland HamWAN. While our frequencies don't have to be the same; it will be simpler if they are. At the ORRC meeting Sunday we discussed the 6cm Ham Band Plan. I am to give a report and recommendation at or before the next meeting. I'll follow your lead on which plan to use. On my initial request I had added the 5MHz for Guard at the upper edge. 73 Ken Tolliver K7ICY Portland HamWAN FYI: Your current HamWAN 10 MHz Plan 10MHz Sector Plan 10MHz guarded 10MHz channels CH Low Center High Bearing 1 5.915 5.920 5.925 0 2 5.895 5.900 5.905 120 3 5.875 5.880 5.885 240 5.925 is the very top edge of the 6cm Ham Band.
