Canada's time-signal station, CHU, is now making the following brief announcement during even-numbered minutes: "CHU has been licensed to continue broadcasting on 7.335 MHz." (The same message is heard in French during odd-numbered minutes.) To those who made known your concerns to the National Research Council regarding the possible loss of this valuable transmission—on a frequency best heard at night, when astronomers dabble in their "occult phenomena"—the effort appears to have succeeded.

For more information on the CHU review see the Government of Canada's website at:
