Yes a very small change is hard to detect. Also you have
field strenght variations from one day to another or
also variations during the day, ofcourse doing a A/B
test would null that out but still.
Again we have proved that 60 1/4 wave radials is a very
good number

I tried 15, 30, 60 and 120 radials on a 40 meter vertical.
It improved up to 60 radials, but there was no measurable
change going from 60 to 120 radials.  The receive antenna
was about 800 feet away.

and then the crew at the

transmitter would

double the number of radials. They repeated this until no

improvement was


noted, then backed down to the previous number for optimum.

And they ended up with 60 buried, 1/4 wavelength radials.
