Want to catch WWV–the Fort Collins-based time station–on a frequency they haven’t used since 1977?<\/p>\n

The National Institute for Standards and Technology (NIST)<\/em> has sent out a press release stating that, as of April 4, 2014, WWV will resume broadcasting on 25 Mhz for a limited time.<\/p>\n

NOTICE: Experimental 25 MHz WWV Broadcast<\/strong><\/p>\n

As of Friday, April 4, 2014 WWV has resumed broadcasting on 25 MHz on a limited, experimental basis. The broadcast consists of the normal WWV signal heard on all other WWV frequencies, at the same level of accuracy.<\/p>\n

Current 25 MHz Broadcast Specifications (subject to change):
\nSchedule: variable; as an experimental broadcast, the 25 MHz signal is not continuous. It will typically be on the air from approximately 1500 \u2013 2100 UTC Mondays through Fridays, but may operate outside these hours as well. The broadcast may be interrupted or suspended without notice.<\/p>\n

Radiated Power:<\/strong> varies; no more than 2500 W<\/p>\n

Antenna:<\/strong> broadband monopole, coordinates: 40 deg. 40′ 50.8″N, 105 deg. 02′ 32.6″ W<\/p>\n

Listener comments and reception reports may be emailed to: wwv@nist.gov<\/a>, or sent via postal mail to:<\/p>\n
