ARLX007 WWV Centennial Committee Prepares for Trial Run of WW0WWV
Special Event

The WWV Centennial Committee reports that it will conduct a trial
run of special event station WW0WWV over the August 24/25 weekend.
Radios and antennas began arriving last week, and a tower and beam
will be erected, along with several vertical antennas. WW0WWV will
be set up adjacent to the WWV transmitter site in Fort Collins,
Colorado. WWV turns 100 years old on October 1.

"We'll be testing band and notch filtering, in an attempt to reign
in the extreme RF environment created by WWV and WWVB," said Dave
Swartz, W0DAS, of the Northern Colorado Amateur Radio Club (NCARC).

The club will carry out the special event operation in conjunction
with the WWV Amateur Radio Club and the National Institute of
Standards and Technology (NIST), which operates WWV/WWVH/WWVB.

The special event site is within 1/3 of a mile of all six WWV
transmitters and the 50 kW WWVB transmitter. "On-air tests will
start Saturday afternoon, August 24, and run through Sunday, August
25," Swartz said, adding that organizers will post specific times
and frequencies on the WWV Centennial Committee website.

The WWV Centennial special event is set to run from September 28
through October 2, and round-the-clock operation will take place on
CW, SSB, and digital modes. Operations will shift among HF bands
following typical propagation and will include 160 meters as well as
satellites (SO-50, AO-91, and AO-92) and 6-meter meteor scatter.

Up to four stations will be on the air for routine operations. A
fifth station will schedule contacts with schools, universities, and
museums, as well as conducting unscheduled contacts. The additional
station will periodically broadcast an AM carrier from a radio
locked with WWV's 10 MHz signal.

"At this point we have filled our operator's slots and met equipment
goals, but we need more financial resources to cover basic operating
expenses, return shipping, and site logistics," Swartz said. Members
of the Amateur Radio industry have contributed equipment, including
radios, amplifiers, and antennas.

NIST has announced that it will not be able to open the doors of WWV
to the public for the event. "Due to a number of reasons, the scope
of the formal celebration will be limited to only 100 invited
participants," the WWV Centennial Committee announced. "WW0WWV will
be the main public event for the centennial celebration."
