Reminder - AMRAD Meeting July 18 - Next Week

[Karl W4KRL]

Thursday, July 18, 7:30 PM, Dolley Madison Library, McLean, VA.
<http://www.fairfaxcounty.gov/library/branches/dm/>  Dr. Frank Eliot, W3WAG,
will discuss Weak Signal Detection.

NOTE: This meeting will be on July 18, the THIRD Thursday of the month.

Thanks to the rapid increase in digital processing availability, hams have
implemented sophisticated and user-friendly techniques that enable us to
communicate with much weaker signals than we had dreamed of exploiting just
a few years ago. In this session, Frank will stimulate a discussion of weak
signal detection, exploring under what circumstances we might detect even
weaker signals, thus communicating over even more difficult paths. Also, on
a related topic, he will describe how earth antennas behave, and experiments
one might perform to sort out their modes of operation.
