WWV Keeps On Keepin' On at 25 MHz

An "experimental" reactivation of WWV's time and standard frequency transmissions on 25 MHz is continuing after a year, according to the ARRL Letter, with no plans as of now to discontinue the broadcasts. WWV had shut down its 25-MHz transmitter in 1977 but reactivated it a year ago in response to an e-mail lamenting its loss from Dean Lewis, W9WGV. The 1-kW signal provides not only exact time and frequency, but helps serve as an indication of propagation conditions on 12 and 10 meters. WWV welcomes signal reports and listener comments.
