John - You aren't an Amateur Operator, no one has any idea as to what 
you use for references, AND you always get in the middle and begin to

I would suggest you "try" and find one of the three references I have 
already given that I can go page for page.

Otherwise your contribution is meaningless.

The table is NOT dBm NOR dBM.  It is labeled as dB.
