Disappearance of Short Wave Time Signals at 5, 10, 15, 20kHz

are on 5, 10, 15 and 20MHz, not KHz, and I think WWV is back on 25MHz"

I am severely dyslexic and always confuse what's in
mHz or kHz. But I have distinct long-term memories
of these time signals being much easier to pick up
decades ago than now, merely by flipping up the
telescopic antenna on the radio or boombox I was
using then. Didn't have to be right near a window or
have an external antenna.

The wikipedia article also mentions, about halfway
down, a power reduction at one or more of the sites
transmitting time signals, around 10 years ago.

Perhaps people just don't rely on broadcast signals
for accurate time anymore? Getting the time from a
shortwave source guarantees next to no latency
issues, unlike getting those same signals off the
internet or the telephone. Yes - it matters. that.
much.

I guess I have to respectfully ask what you are doing that requires such
critical timing...

For my ham station I am operating the JT9 and JT65 modes that are *VERY*
sensitive to timing issues; there are several free apps (Dimension 4,
for one) that will adjust your computer clock. Internet latency has not
been a problem, keeping my computer clock within milliseconds. Would
being within milliseconds be close enough for your application(s)?
