Joe, If all you need is a fixed 10MHz source, you might be better getting an Efratom LPRO-101, which are available from the same sources. The LPRO-101 doesn't need a heatsink, and does not have the confusing array of different versions and options that the FEI units suffer from.
As for suppliers, I have had good results with 'Fluke.1' also known as 'NBBob', and probably other aliases. He is fast and reliable on delivery, and replaces faulty equipment without argument. I have no experience with any other suppliers. Most of these suppliers seem to have little knowledge of what they are selling, so don't trust the technical details given without checking them yourself. 73, Murray ZL1BPU _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
