Damn --but I guess I should expect that of you.
I said; "The approximate formula ls:" -- and I didn't make it up. It was to explain that there is a very high field at transmitter sites. We shuld not care if it is 100,200,300,... volts per meter. It is way too high for unshielded receivers to work reliably.
