[net.followup] WWV

At first reading I thought WWV stood for World War V.  Soooooo glad it
hasn't come to that.

Relentless!

Heathkit sells a clock kit which monitors the WWV broadcast and
sets it's time to within 10 milliseconds of Coordinated Universal
Time (or any other time zone you may happen to program into it). During
the times which the clock cannot receive WWV do to interference there
is an internal clock which keeps time.  The clock has an indicator which
tells if the clock is synchronized to WWV.

There is also an RS-232C serial port option which runs at up to 9600 baud,
with which a computer can get the time from this miraculous little clock.
I think that those people whose machines have problems with "What time/day
it is", should get one of these clocks.

In kit form this clock costs about $250.00, with the serial port option
about $300.00.  If you buy the clock assembled it costs around $389.00.

I normally would expect no more than a one second delay, as an absolute
maximum, for calls to WWV from the continental U.S.  Actually, the
delay will be far less if you've been routed exclusively over cable/
terrestrial microwave facilities, and normally would only start becoming
"considerable" if satellite routing is involved.  If you want consistent 
results for time setting, go out and buy one of those cheapo (under $100)
WWVB (longwave) receivers which can be fed directly into computers.
At longwave frequencies, propagation characteristics are essentially
fixed to any given location and are very reliable.

By the way, (800) 957-9999 for WWV works fine from here in 213 land.

A reminder, you can call the WWV recording at 1-800-957-9999.

Northwest area. I have tried it numerous times, and merely get a recording
telling me that my call cannot be completed as dialed. Dialing a 1 before
the 800 is not the problem.  Any comments or suggestions?

Quite a feat, there, synchronizing an recording with an atomic clock.
Anyway, that phone number is kaput as of before 11/5/83.
