W8JI asked:

Why does it matter anyway? Doubling the distance can mean
more than 10dB change in level, not 3dB. This isn't
freespace. The path loss is not in a linear relationship
with distance, and no one knows what the antenna efficiency
or pattern is anyway.

Mile per watt is a "fun thing". We shouldn't take it as a
standard that can be converted to distances other than the
one actually covered. Who cares if it is 10dB one way or
another?

Still waiting for a mailer-daemon message to come back for my first attempt at my post.

I merely wanted to point out that the power levels used are
probably not what they are thought to be, as the instrument
used is a bit sloppy for absolute measurements - even if in cal,
sufficiently warmed up & self-cal'd beforehand.
