WWV Time & Freq Standard -- An Introduction to WWV Services
WWV Broadcast Format In Clock Picture Format
Low-frequency radio time signals
Canada CHU Time Standard Service
From The Internet News Groups
Most time signals outside the US are within a few khz of 5, 10, and 15 Mhz,
because there's a narrow band around those freqs that is Allocated for time
signals. (There are also allocations for 2.5, 20, And 25 Mhz, but they are
rarely used. NIST canned its 20 Mhz outlet Years ago.) Most of the foreign
services try to avoid competing Directly with WWV/WWVH, except Venezuela, which
has a time service That directly competes with WWV. (Hugo Chavez loves to tweak
the nose Of the US any way he can.) Increasing numbers of foreign time services
Have been shelved for good in the last decade due to aging equipment And lack of
funding. The Soviets, then the Russians, had a time Station that is likely no
longer active. VNG is gone, which outraged Australian owners of radio controlled
clocks that used VNG's VLF time Signal. There were services in Chile and a few
other places that have Disappeared. Only England, Germany, Japan, and the US
maintain VLF Time signals. The main HF signals are in the US, Canada, and
Venezuela.
Older List -- Some may be outdated. Some of these stations may have
certain specific times of transmissions. They are, however, a resource for time,
frequency and propagation beacons.
