Hello,

While digging into the source, I saw that I was wrong saying that; only
the default is hardcoded set to .2 and if one provides an argument on
the cmd line, this is used; don't know how I have overlooked that;
Edwin, please accept my honestly sorry for this;

I did some minor cosmetic changes (attached) for your consideration;

in any case, now I have it clear why in some place where I sit reading
with my netbook, the bandwidth and speed is so poor: the RSSI value
there is only 2-3 in that place; it is a relatively new building with a
lot of steel and concrete; the distance from the table to the windows is
around 5-6 meters; when I move to the window the RSSI value is ~14,
outside as well; in short words: your tool, Edwin, helped me a lot to
get a clear picture of my problem; thanks!
