No, they are not "meaningless". They are a relative measure of noise
levels in various locations, which was my purpose in making them. I
would gain absolutely nothing more from measuring absolute field strength.

On the other hand, it could be a lot worse.
There's another BIG reason -- look at VE6WZ's RX antenna farm. Then
look at NO3M's. I don't know what Dave has, but I'll bet it's serious
too.

Your numbers are meaningless, because you're measuring signal level,
not field strength, which must be done with antennas calibrated for
the purpose.
