[TenTec] ARRL's BPL NPRM response is out

[Carl Moreschi]

That's a good point to bring out.  Point source radiation drops off at the
inverse square rate, but line source only drops off at the inverse linear
rate.  In other words, for a point source, doubling the distance causes the
signal to drop to 1/4 the original value, but for a line source, doubling
the distance would only cause the signal to drop to 1/2 the original value.
