Hi all,I'm looking for some sort of frequency standard (10 MHz ref.?).Ebay has rubdium frequency standards for under $100.00 and there are also GPS disciplined OXCO frequency standards for~$150.00 .My question : Is a 10-20 year old rubidium standard more accurate (even with agingdrift) that a newer GPS disciplined OXCO?I can't afford a GPS corrected rubidium standard ( ~$700.00+).I just want to recalibrate my so-so frequency counters .. to hopefullywithin 10 Hz..?Opinions?Thanks for reading! :-)Cheers!Bart
