Dustin, thanks for the encouraging support of my efforts. 

Since we have been hired for part of this project, I believe it is my
RESPONSIBILITY to point out any known issues to the customer; and, it is
my responsibility to back up my concerns with hard date, not just 'my
feelings.' In the event that the data doesn't show what I know to be in
the area, I will at lease be on record for making them aware of other
5Ghz RF in the overlapping areas.

I am interested in any information that you are willing to supply for my

Again, thanks for all of the feedback and discussion in my topic.

Takes no more than a few minutes to perform a peak hold Bob,  maybe you
should get one and play with it a bit.  It's a very powerful tool and I
think your opinion will change.   

I agree that we have two different schools of thought. 
1. Plan the play, play the plan.
2. Show up for the game.

Cliff was doing the right thing by doing a spectrum analysis, esp
that he was going to go trough some existing equipment.  Anything short
that would be irresponsible.  I would say to Cliff that if they cannot
produce results from the analyzer, graphs and charts than it's worthless
done improperly,  just because you have an analyzer doesn't mean you
how to use it.  

If it's helpful I will post some shots to a website if Cliff thinks that
is helpful.

I don't know about you but I'm not about to leave a spectrum analyzer 
180' up a tower for any period of time.

I am not saying to blow people out of the water with power. I am saying 
to make sure you have ample power and gain to supply a solid signal. 
Running at -78 on a link is not a solid signal in my mind.  We only use 
equipment where we can control the power. We don't run full bore unlike 
alot of WISP operators. We don't plug radios like Motorola Canopy units 
into omni's. And my opinion is if I blow that guy off the air, so be 
it.  It was not properly engineered to begin with. It was finacially 
engineered to get by cheap.

But the point is moot if Johnny O comes along on your channel tomorrow 
and blows you off the air (I am only using him as an example).  Then the

customer is all pissy because he spent money for spectrum analysis that 
was totally moot.

I don't think a properly engineered link is chance luck. We don't just 
pick a channel out of thin air and go with it. Alot of engineering goes 
into it. Spectrum analysis is just not a factor 99.999 percent of the
