[time-nuts] Motorola GPS + 5 MHz oscillator ?

[randy warner]

Bill,

This one of the old Motorola "Basic" receivers. Is it in a plastic box or an
aluminum one? Doesn't matter, just curious. 

Many years ago I created a PDF version of the old VP command set which is
supported by the Basic. I think Jason Rabel has a copy on his website.
Jason, are you out there? Can't remember your URL.....

For instant gratification I would recommend you download TAC32 from Rick
Hambly's website:www.cnssystems.com (I think it is on the TAPR site too.
TAC32 will automatically go through all of the messages on power-up needed
to identify the receiver. Once you know that we can make a pretty good guess
on which commands it will support.

It's also a quick way to see if the receiver even functions.

I have a friend who has  two of the surplus (telephone Co. ?) timing 
receivers. That use a Motorola
(A111219115) GPS receiver and a ovenized 5 MHz oscillator

It has external connectors for 5 MHz., 1 PPS, -48Volts, RS232, and the 
Antenna.
He has the matching Antenna which is marked 5 Volt and looks like it has 
a helix inside.

What I want to do is get one of them running so I need to find the 
correct commands to set the
Lat and Long. and read the status messages.

Anyone recognize this equipment?
