Emery Sent: 15 October 2012 17:30 To: time-nuts@febo.com Subject: [time-nuts] Antique 5061A option 004 In a mad moment at the NEARFest flea this weekend I grabbed a 5061A for $250. Poor thing was getting wet in the rain and needed a home. Really really heavy to carry to the car, however... It has a high performance option 004 CBT in it (late SN 3112A02887 dated 05/93). And a 10811-60109 OCXO. Option 3 whatever that is, and H29 too. Seems to have a BNC marked C field... Chassis SN is 2002A01710 but a number of the modules have late series numbers such as 2740 for the synth, 2652 for the oven controller, and 2448 for the AC amp.. The unit obviously came from the Naval Observatory (similar to Paul Swed's I presume)... has a sticker on it. Looks superficially as if it was upgraded various times - wondering if anyone could suggest where a manual that would cover the OCXO mod and others on into the 90s might be had (Artek ?) I have yet to fire it up (gotta dig out a power cord I have somewhere in the way back junque)... but FWIW (not much I am sure) I was told it would lock "after a while". I suppose it is time to see if it will pump down and have any measurable beam current - I guess at least possible that a CBT that young might still have a tiny bit of life left. A question - I assume the OCXO is 10 MHz (I think all 10811s are) and thus it obviously must be easily possible to provide a 10 MHz output. Is there a point to attach a SMA to BNC for this ? It is my first Cesium, now I guess I officially have the disease, all those Rbs and GPSDOs being just prodromal syndromes... I also grabbed a PRS10 at the flea (that was pretty cheap at $50) and wonder where I might land a PBBT adapter for it cheap too... I'd rather see if it works OK before investing in a new one first... and that connector is a bear. -- Dave Emery N1PRE/AE, d...@dieconsulting.com DIE Consulting, Weston, Mass 02493 "An empty zombie mind with a forlorn barely readable weatherbeaten 'For Rent' sign still vainly flapping outside on the weed encrusted pole - in celebration of what could have been, but wasn't and is not to be now either." _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
