This appears to be a compatible part for the DE sized connectors: http://www.newark.com/harting/09-67-000-9914/slide-lock-de/dp/93C7911 Search through the technical data sheet for "9914" and you'll see it listed for 9 pin connectors. Of course, these may be completely wrong so do your homework a

Hi There is a lot of *stuff* in an Rb beyond just the lamp. It *could* be as simple as a VCXO centering adjustment. It also could be an alignment adjustment. I don’t believe there are any schematics out there on these devices, so it’s a “trace it out and see” sort of fix. Even with the schemati

Hi If indeed these PRS-10’s are out of TS boxes (and that’s a real good guess) there is one other thing to consider: Not all PRS-10’s are created equal. Some have fancy disciplining firmware in them. Some have better temperature specs. Some have better ADEV specs. Some (may) have longer runnin

Thanks for the discussion on this GPSDO. I researched the archives on this going back a few months but didn't find anything. Although I consider myself a newby or novice Time-Nut I do have three other GPSDO's I've had a Z3801 running for more than 10 years. My interest in the unit in question

I have seen D connectors with the these lock type fittings before but never did know their correct name. I tried a variety of Google searches but never did find what I was looking for. I just never looked for D connector slide latches or slide locks. Because I didn't have the correct fittings

My experience has been similar to Vasco's. Of three defective PRS-10s acquired for about $100 or less each, one had a bad MiniCircuits 400 MHz VCO module and was an easy fix. Another had a rubidium bulb issue that I traced to the driving FET. I managed to replace the FET, but the replacement'
