This is very important.

I asked ARRL Lab Tech Bob Allison about it, and he said the two radios 
were in the same class noise wise. He said  "at 100 kHz from the 
carrier, both have nearly the same composite noise. This not an issue."

Sometimes you guys talk about "phase noise" and other times "broadband 
noise" as if they are the same thing.   Are they?  Am I on the wrong 
page?  I thought you said the ARRL has data, but other times no.

Mr. Allison's whole message follows, so no one will say I am taking 
anything out of contest.   I was encouraged to press on because he 
seemed to support my position.

Where is the disconnect ?   I am sorry if I don't see it.
I thought I was looking in the right places.

Subject: RE: Transmitter Noise  Issue  Puleeeze help !

Looking at the composite noise on our web site (Product Reviews by 
Manufacturer), the Eagle is a little bit better in the composite noise 
area than the TS-590S, but both are considered reasonable. The only time 
when this issue would come up would be Field Day, when two transceivers 
are trying to use the same ham band; one on phone, one on CW. In such a 
case, the stations would likely be at least 100 kHz apart from each 
other. Thus, at 100 kHz from the carrier, both have nearly the same 
composite noise. This not an issue.
