Recently N2XE ran an 80 meter beacon at very low power levels. I listened
but
never heard him. I have participated in previous beacon tests on 10 mHz
from
AA4XX and extremely low levels of power and software that would decode
signals
below the noise level. However, the N2XE tests were CW not requiring
processing.

Amateur Radio Set New World Record, 13 Million Miles per Watt:

Amateur Radio Set New World Record, 13 Million Miles per Watt:
January 2, 2005 New London, NC
Bill Tippett, W4ZV, of New London, NC correctly copied code word OMAHA from
the N2XE beacon transmitting with a peak carrier power of .0000406 watts at
3.5455 MHz on the 80 meter Amateur Radio band. Bill confirmed reception of
the beacon at 2328Z, January 2, 2005. The precise distance between the two
stations is 546.8 miles, establishing Bill's record reception distance at
13,467,980 miles per watt. Tippett used a Ten Tec Orion Transceiver with a
1000 foot Beverage antenna (named after Dr. Harold Beverage who invented it
in the 1920s).
The N2XE beacon transmits from an Elecraft K1 (heavily attenuated) using an
80 meter off-center fed dipole, 45 feet AGL (above ground level). The
beacon peak carrier output was measured using an Agilent 8563EC Spectrum
Analyzer at 40.6 uW (40 millionths of a watt). The beacon transmits a
unique code word each evening. Receiving stations are required to correctly
copy the code word in their report. The word is published the following
morning.
The N2XE Beacon Project was started in December, 2004 by Paul Stroud,
AA4XX, Raleigh, NC and John Ceccherelli, N2XE, Wappingers Falls, NY with
the goal of having a little fun and to go where no diminutive signal has
gone before. Beacon times and frequencies are posted daily on the QRP-L
reflector www.kkn.net/archives/html/QRP-L. Tests will continue on 160, 80
and 40 meters through the end of February 2005.
Commenting on his remarkable success, Bill said "I've spent 25 years on 80
& 160 listening to below noise level signals. There are at least three
factors to this stuff: Antennas with good signal to noise like Beverages, a
good receiver and the knowledge to use it and an operator with good ears
and knowledge of propagation--not to mention patience and persistence."
Beacon station operator John Ceccherelli, N2XE, seemed more exited than
Tippett about the achievement, even though it requires almost no effort on
his part. "Hey, I have to flip the switch, grab a beer and go watch
TVthats effort" he's reported saying, adding Im thrilled the record was
set by an all-American team using all-American equipment. The Ten Tec
receiver is manufactured in Severville, TN and the Elecraft transmitter is
produced in California and offered as a kit.
