Wasn't it, “This is WWV, Fort Collins, Colorado. (small pause) The next tone begins at
(short pause) X hours, X minutes, <font color="#006600"><u><i><b>Greenwich Mean Time</b></i></u></font>” ?? It's been a long time since I've heard it, but I used to listen to it for hours... well, maybe for ten minutes... at a time!!<br>

<div>Hello David,</div>
<div> </div>
<div>How’s things going for ya??</div>
<div> </div>
<div>My first thought is it’s a frequency standard for radio work. It’s
not big enough for 100 cps so I don’t know what that number is. I’ll
forward this over to my brother who at the age of 12 built his own ham radio
transmitter. </div>
<div> </div>
<div>In the olde days you had to “align” receivers by tuning the “IF cans” so
that they’d operate at their optimum. A frequency standard was used to
accomplish this. Station WWV was the source for this. At various
places on the ham radio dial you could find this station located just outside
Wellington, CO. Every minute they’d announce the geophysically correct
time. A tone would pulse every second for 50 seconds and then the
announcement would take 10 seconds to complete. After many hours of
working with this radio source in my youth, I can still remember the
announcement.</div>
<div> </div>
<div>“This is WWV, Fort Collins, Colorado. (small pause) The next tone begins at
(short pause) X hours, X minutes.” Then there’d be another short pause and
the first tone would be slightly longer than the others. At 30 seconds
there was a double click I think.</div>
<div> </div>
<div>The “metric” version of this was CHU CANADA, announced in French.</div>
<div> </div>
<div>Regardless, it looks like someone needed an electromechanical frequency
standard. 20 years ago they could have produced a solid state version of
this but I guess there were some stability issues to deal with.</div>
