Kevin,

That hardly makes sense.  If the beacon is 10 over, yet the noise floor is
S7, 8 or 9, what is getting a bigger dish going to do???  You don't make
sense.  A bigger dish isn't going to make the noise floor less.

Rather, Kevin, the real scoop is more like this:

BBQ dish: 

Beacon = S8 to S9
Noise: S0 to S1 - BUT THIS IS NOT THE Transponder noise floor!


3' Dish:

Beacon: = S10
Noise: S3  - Now you are hearing transponder noise.

These sort of numbers I would believe if you put them forth.  They make more
sense.
