Right, lacking this lab equipment, i couldn't do this tests.But my sense
of logic tells me, that I card stated to have more than 6 times the
output power and according to a chart found in the web (dont remeber the
link)a better rf sensitivity, it should at least perform equal to the
old one, shouldn't it.

I think i always did this.

Yes I know, but remeber the thing about 'lacking the right equipment' :-) ?
Thanks for your thoughts anyway!
