[time-nuts] Lucent RFTG-m-XO GPSDO

A while ago, I invested $600 in two pairs of the GPSDO and LPRO units.
Intended to replace a pair of 48 volt Z3801 receivers with 24 volt units.
Put them in the project pile for lack of drawings and software, where
they have languished. Their value has dropped, but I'd still like to
have 24 volt receivers with software like GPSCon that can do SNTP.
RS422 is no problem.

Please let me know if you find drawings and software. Copies are
worth more than postage to me.

I will look for my drawings on this unit and send copies to you.  And I know
I have the software too, just need to find it!

I have read in some of the notes here on time-nuts that people may be able
to use RS232 for communicating with the RFTG units.  But it was designed for
RS422 and I would suggest you use RS422 for best results.  I use a little
RS422-4S232 converter which has worked fine for me.

The early units had FRS rubidiums in them.  The LPRO was used in the newer
units.  So, you have the more recent design.
