 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.    73, Dick, PA0SE At 07:17 24-11-03 -0800, you wrote: Hi Eric and all, Dick's post, made with Eudora, contained this HTML fragment: The correct formula is:

The correct formula is: P = 0.0111 * (E * d) ** 2 or P equals 0.0111 times ((E times d) squared) Hope this is clear. 73, Stewart ----- Original Message ----- From: "Eric KD5UWL" <[email protected]> To: "LF-Group" <[email protected]> Sent: Monday, November 24, 2003 6:44 AM Subject: Re: LF: PA0SE Field Srength Meter for 137 kHz > On Mon, 24 Nov 2003, Dick Rollema wrote: > > > produces a certain field strength is wrongly given as > > P = 0.0111(E * d)2. > > > > The correct formula is: > > > > P = 0.0111(E *d)2 in which: > > Hi, Dick, > > Sorry -- I don't see the difference.  Did you include the wrong one? > > 73 > Eric > > >
