It's not a commercial unit. As it says at
[1]http://www.maxmcarter.com/rubidium/index.php, " Almost 30 years ago,
I built a receiver for WWVB roughly based on a Don Lancaster design."
Apparently this refers to an old article, " Don Lancaster,
Experimenting with WWVB, Radio Electronics, August/September 1973".

Thats what I was reading. But have to say I have never seen a
commercial divider chain that could be changed. The spectracoms
divide to 20 Khz and mult by 3. So would like to see that circuit.

Also curious on the rcvrs doubling to 120 KHz another multiplier or
did the
rcvr happen to have a way to change that frequency? The note says
that the
rcvr local carrier doubled.

Have you actually tried it and gotten it working, except possibly in

A tuned antenna probably is going to provide all the selectivity
you'd
need.
Another possibility is to modify your old circuit like that:
