Re: LF: PA0SE Field Strength Meter for 137 kHz

To All from PA0SE,

Many thanks to Stewart and several others who explained what went wrong
with my e-mail for some subscribers to the reflector.

I emphasize that the formula can only be used within  distances from
the transmitter where  the field strength decreases  in a
linear way with distance and attenuation due to absorption by the ground
can be neglected.
