[time-nuts] New NTBW50AA

[Mark C. Stephens]

No worries, Dave, 

these Nortel/Trimble things are good bang for the dollars.

My first one is sitting in the e-13's for PPS and OSC already - it's only been on 36 hours.
I did replace the OXCO with a MV89A as the original osc was faulty, but, then again it only cost me $21.00 :)
That's not quite as good as my best Z3805A (yet ;)

Everything here runs off 24V, but don't forget the higher the voltage the less current you need too..
I have heard of people running as high as 55v, shocking huh?

Not familiar with that term, but I hope the pigs chundered your little bro up again :) 

I got one of Bob's latest and greatest board, puts out a whacking great +10dB, so it can go straight into a case with no buffer required.
I found a bunch of connectors for the backplane in the junk box. I'd love to get that orange LED to go green!
Bob said 1PPS is lurking on the backplane too.

Thanks Mark, yeah, I think I'm getting the hang of this thing.  The ADEV is down to 1.032e-008 by this point.

I think the red light was on because it was going out of lock, it couldn't find the satellites until I did a survey.  Then things started coming into perspective when it found my position.  At one point the osc was listed as bad.  I just turned it off and started again and it seems fine now.

Nothing seems even warm on the board with 30VDC going into it.  That brick I had, I couldn't get the voltage out of it, so I canned that one.  I think I can find a smaller supply than I've got though, this one is an old 10A 12V linear regulated supply that the regulator went out in.

I haven't had this much fun since the pigs ate my little brother.

Dave
