I said I would follow up so here goes. We made the change today and its working fine in the new configuration. It’s the only site where we had run both vertical and horizontal polarization so It doesn’t matter when we migrate the other sites. But for some of you out there it might be helpful.

Sean, I left out a key piece of equipment. There is a third FSK channel C in the mix I didn’t mention and its on an Omni so I was using all 8mhz FSK channels before introducing the 450i. That Omni is what’s killing me right now but if I get a different configuration on those panels I can balance it much better. I do have to think about what you said though for down the road. Is there enough spectrum to run two FSK 8mhz channels and two 450i 5mhz channels and still leave guard channels in place for the FSK?

Can u squeeze the 450i into a 5mhz channel? That way you could put the 2 FSK on 8mhz A,B and then the 450i on two 5mhz C,D? Once you are done converting you can then switch the 450i into two 10mhz channels (and even a third 5mhz one inbetween) if you want. -Sean On Sunday, February 14, 2016, Brandon Yuchasz <[email protected]> wrote: Jerry, Thanks I guess we will give it a try. Right now we have it sliced up into 40 degree panels. So we had an ABAB configuration on horizontal. Above the center two (BA) I also had a AB in horizontal. When I turned off B to use that frequency on the new 450i I of course created some serious congestion on the remaining FSK. So my current configuration is O = off , A,O Horizontal A,O,A,O Vertical I would like to try and do ,A,O O,A,O,A This will give me a better balance until we can convert more to the 450i. If anyone else has thoughts please chime in. Ill be sure to report back. Not that many people are doing FSK 900 but hopefully many are migrating.

Nothing new everyone runs into it I am sure. My question is has anyone run FSK 900mhz on the same frequency on both vertical and horizontal polarities with just vertical separation on the panel antennas?� I have done this in the past but we always offset them in an AB horizontal and a BA vertical. In this case I want to stack them directly above each other� AA no B. Clear as mud? We have a break in the weather coming next week it should be in the 20�s with light wind but I don�t want to waist a climb and a day if its not going to work. � � Best regards, Brandon Yuchasz GogebicRange.net www.gogebicrange.net <http://www.gogebicrange.net/> �
