I'm having a problem with a sentence that contains "bad" and 10811 in proximity. It sounds like an oxymoron.
Please could someone elaborate on why a 10811 OCXO in a 3805 is bad?

Hi The "bad units" with the 10811's in them are usually marked "HP". The "good units" with the true DOCXO in them are normally marked "Symmetricom".
