Go for it, Dave, it works very well. I have used a Racal-Dana 9475 Rubidium standard (perfectly safe!) and also a GPS disciplined 10MHz standard, but recently got a 10MHz MV89 double oven CXO which is inexpensive and excellent. Mine is accurate to the nearest one-hundredth of a Hertz at 10MHz, which is near enough for me ;-) Search eBay for MV89 and MV89A. I built mine into a box with its own 12V, 2A regulated linear PSU. After warm-up it draws just 9W from the supply mains. 73 de David G4DMP -- + - - - - - - - - - - - - - - - - + | David M Pratt, Kippax, Leeds. | | Website: http://www.g4dmp.co.uk | + - - - - - - - - - - - - - - - - + ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
