Changing the thread slightly, where do the Efratom FRK- L and H fit in the hierarchy of Rb quality? I guess somewhere between the telco units and the 5065A. Opinions welcomed! Robert G8RPI.

Ruifeng is specifically looking for hp 5065A. For a certain mid-range of tau there nothing sort of a maser that beats a well-working 5065A; "they don't make 'em like they used to". As others have pointed out none of the telecom rubidiums come close. For that reason the price of 5065A is deservedly very high -- in equivalent condition they are worth far more than any 5061 cesium beam standard, for example. Unfortunately what Ruifeng has never disclosed is why he needs 5065A's; what exactly his company does with them. Since Ruifeng has now joined our list -- now would be a good time for you to come clean and tell us the details; we might be more sympathetic to your company's needs, eh? /tvb _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
