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 The Soviets, then the Russians, had a time Station that is likely no longer active.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.
