[comp.dcom.telecom] Western Union Clock Service

Well, after reading the myriad posts about the Western Union Clock
service and deciding that I just >>had<< to get one of my own, I
reached for the nearest yellow pages and talked to just about every
clock repair shop and antique dealer who would pick up the phone.  My
search ended with an antique dealer in Omaha.  He said he had two of
them (standard wall model, I assume).  He was at home (got his calls
forwarded) and said he would sell them for "100-120 bucks or so."
Does this sound like a fair price?  Since he DOES have two, someone
else can snap up the other one.  Mindful of the Fidonet ban on
"advertising", I will let prospective buyers contact me at home via
the telephone.  I have no financial interest in any transaction that
will take place between you and this dealer.
 
There was a post on this conference about someone who made a circuit
to synchronize the clock via the telegraph line hookup.  Are these
schematics available?  Are the obligatory SASE's and green stamps for
copying costs involved?  Let me know.  My local BBS sysop deletes
often, so the relevant posts are now in the bit bucket.
 
I was thinking of homebrewing a tone discriminator that would monitor
WWV and listen for that standard reference tone at the top of the hour
(which is different from the tone at the other 59 minutes), detect it
for a fraction of a second (to prevent falsing) and send a
synchronization signal to the clock.  Any ideas on this one?
 
Can't wait to have one of these beauties in the computer room/hamshack
whirring away at the top of each hour.  My girlfriend ALREADY thinks
I'm nuts for collecting "all this wierd junk."

[Moderator's Note: I'd say the price he quoted is fair, assuming the
clocks actually work. If they are not working, you can still cheat by
putting an electric clock works in the case and use only the dial,
hands and cabinet. Regards the various plans for a pseudo setting
circuit, if you think it is worth the time, go ahead; but I can tell
you that if the clock is hung *perfectly level* and the pendulum
calibrated properly (a few days of testing by setting the time and
watching for inaccuracies a day or so later) you will find the clock
stays accurate within a minute or less per month as is. My two WU
clocks do their own thing and when I think of it once a month or so I
set them if they are more than a minute off.  PAT]
