  Close...the Z3801A.  HiTech Cafe has about 1500 of them at $299. (!).
They need an antenna with a preamp, and 48VDC.  These are REALLY
REALLY NICE units, and a tremendous amount of bang for the buck as
either a time or frequency standard (or both).  They have a 10MHz
output for those lonely "ext std in" BNCs on the back of all of our HP
test equipment.

  See http://www.realhamradio.com/GPS_Frequency_Standard.htm for lots of
very good information about this unit, and PDFs of docs.

  They seem to have SprintPCS property stickers on them.  I guess the
suits at Sprint have found something else to stabilize the oscillators
at the towers.
