How do you verify your ERP? Your NoV application must have included
some indication of how you would do it.
How do you ensure your TX power is not excessive, given the self
proclaimed superior location and antenna?
As you say, local measurement of field strength is only the way to do
it.
I've done it, many times, using a laboratory standard, calibrated,
professional MF field strength meter, as well as my own home designed
(I can provide you with the maths for it) loop antenna and calibrated
receiver.
My take off is similarly uncluttered to yours and I've measured FS at
ranges between 600m and 3km, in all directions around my TX antenna.
I presume, as the professional radio experimenter (not appliance
operator) that you are, that you've done likewise? I'd be interested in
your results.
Can you give an indication of the overall loss resistance, the
radiation resistance and radiation efficiency of your wonderful 100'
high 1/4 wave inverted-L, and the resultant estimation of maximum TX
power allowable to remain below 1W ERP?
I guess you'll have these figures to hand, since you are one of the
most technically able, numerate and scientific of the LF/MF community,
by your own, frequent, admission.
