Bob, Have you tried to contact ESE for the information. In the past they've always been pretty helpful on obsoleted goodies. http://www.ese-web.com/ A bit of trivia... ESE originally stood for El Segundo Enterprises. Burt, K6OQK Date: Wed, 28 May 2014 19:38:14 -0700 (PDT) From: Bob

[time-nuts] Caveats on Allan Deviation with ultra stable oscillators

2014-05-29 Thread cdelect
Recently I have been testing some Quartz oscillators with exceptional stability. (low parts in 10-13th) I've noticed something that jumped out at these performance levels! Normally I test oscillators on a DMTD system with either an ultra stable Quartz or a Hydrogen Maser reference. On these

[time-nuts] HP 105/5061/5065 oscillator interface boards

2014-05-29 Thread cdelect
Hi, I'm looking to see if anyone has any 10811 oscillator interface boards to spare? Two boards and a frame that accepts the 10811 and outputs 5Mhz. Used in the HP 105 5061A/B and 5065A. Interested in the whole thing with oscillator or just the two boards or just the bigger rectangular board

Burt: As I mentioned in my post, ESE had only the digital board schematic, not the receiver board.   I am hoping that an existing customer from a b'cast station or other such entity migh have an original manual. I was disappointed that they didn't have the product support material available in
