756 PRO/II and purch SDR-1000.I do not ever and have no interest in
transmitting.
OK,my question:
While editing(checking if still valid)an extensive bookmarks list,I came
upon N9VV site and saw an article by K2WS regarding a very stable
oscillator he built on a perf board for use with SDR-1000 but BLILEY
refuses to sell the oscillator considering it proprietary,apparently to
K2WS,from whom I have been unable to obtain further info.I may very well
not..at all..need the described stability but I don't truly...need..so
called "atomic clock"wrist watch either!
Has anyone read the article and..pursued this?

So you asked for a quote for a Bliley 535-471229-001?
have you looked at Bliley's off the shelf inventory?

All those N26 series oscillators are probably in the ballpark.
What sort of stability and/or close in phase noise do you need?
0.03 ppm (3E-8, 30 ppb) over -20 to +70 with -100dBc/Hz at 10 Hz is
probably available from other oscillator suppliers as well. The phase noise
spec isn't all that aggressive, but if you could tolerate a bit looser
frequency spec (or, you don't need that wide a temperature range), you can
probably save a fair amount.
for instance, I would imagine that one can get an oscillator from Wenzel
http://www.wenzel.com/catalog.html that has that sort of performance for
<$200. I bought a few Streamline 10MHz oscillators last year for about
$250 each, but they have even better performance than that Bliley unit
(-125 dBc/Hz at 10 Hz and 0.02ppm frequency over the temp range)
A search of Ebay will also usually turn up suitable oscillators (although
almost always at 10 MHz, e.g. the HP 10811).. There's someone out there now
selling Isotemp oscillators for $75. The same guy (or gal) is selling a
parts kit with a GPS receiver to discipline it. there's also someone
selling RFE 10811A OCXOs, but I don't know that I'd pay $100 for a used
oscillator AS IS, when I could get a brand new one with a warranty for
twice that.
