TopBand: HEARD better on xmit antenna

[Ward Silver]

I think some of the odd signal strength behavior is due to multiple paths
open at once, maybe close to each other in azimuth.  Since the paths are
so long, their signal strengths vary considerably, over many different
time periods.  This would cause a variety of interference-related changes
at the receiver.  Omnidirectional antennas, by summing all paths instead
of just a few, may act as "diversity" antennas, with better overall
receive levels.
