I just put Dick's data into excel, the trendline says R = 4568/F
Remarkable is that, while the previous data (M0BMU, ZL2CA) gave a very
good
fit, there are a lot of 'bumps' in Dick's data.
This encourages my idea that the measure loss resistance is far more than
just the ground loss.
This could be due to the strange configuration, especially the central
heating system. This is connected to the gas pipe that carries the aerial
current to earth. But that system is also capacitively and inductively
coupled to the house wiring which in turn has its own capacitance to earth..
I also noticed the irregularities but they remained after repeated
measurements, so they are really there.
Question to Dick : do the given values include the coil-loss or did you
qlready subtract it ?
Yes, I did subtract the coil resistance.
