Hi Bert, If you go to the Bama site for this counter:
http://bama.edebris.com/manuals/racal/1991/ You can see references to the Opt 4B, 9423, ocxo in: http://bama.edebris.com/download/racal/1991/RACAL-DANA-1991-1992-UserManual.pdf http://bama.edebris.com/download/racal/1991/RACAL-DANA-1991-1992-ServiceManual.pdf And the Opt 4E, 404386, ocxo in: http://bama.edebris.com/download/racal/1991/RACALDANA-1991-1992-IM.pdf As for what I wanted to know, well I wondered if anyone had experience if one was better than the other for drift, stability, thermal stability, etc. The 4E unit appears to be the more substantial but the specs in the above pdfs seem to favour the 4B with regard to thermal stability. This is really all very well anyway as I would like to use the counter locked to GPS for most of the time but there may be times when it could be used as stand-alone. I guess the only way to tell is to run a test on them both but before I looked into this I wondered if anyone had already done this, that's all. 73, Steve 2009/2/3 <[email protected]>: > I have option E but am only aware of E and A.
