Hi Tony...

Can't speak to your figures, but.....I was always taught that 500 watts from 
my amplifier, not addressing any gain factors in my antenna, will result in 
a 3 db gain on the other end of the contact.  True?  I couldn't tell you, 
just what I have been told.

But......

On average, again, band conditions not withstanding, if I am talking to 
someone and he is cranking 80 - 90 watts barefoot, and he turns on his 
amplifier and pumps 500 watts at me, generally speaking, his signal will 
rise around 5 s-units.

Again, these figures are all 'just figures'...as there are too many factors 
involved that will affect signal strength, etc.    (Gain of the antenna is a 
very important factor......)

Me thinks this is gonna be a good topic...I look forward to all the 
responses....I may even gather them together and post them on our New Hams 
Net Forum here in Reno.  (With Talkian permissions, of course)
