Just curious about whether anyone ever hears this time signal. I've
listened for it without success. It appears to be active.

My (no doubt weak) translation, courtesy of babelfish: Transmission
of hour signals in HF, during two periods of 25 minutes daily, in
15006 and 4998 KHz. Respectively, between 10:00 and 11:00 hours UTC.

From your posting IP I suspect that you are in NYC. Does anyone
have any reason to believe that these signals separated from WWV
by only 4 and 2 kHz respectively could ever be resolved in NYC?

Perhaps European readers have copied those signals; also under
remarkable propagation conditions it is conceivable that they could
mix with WWV in the States, much like WWVH is often mixed with
WWV here in the Northern Midwest (the female voice from WWVH
always speaks during silence of the male voice from WWV).

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station that is likely no longer active.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.
