); SAEximRunCond expanded to false Errors-To: [EMAIL PROTECTED] RETRY Stan's comments below about his noted errors between LORAN & GPS that range from E10 to E13 each day remind me of the similar errors that I have observed.
I had originally attributed them to ground-wave vs. sky-wave propagation on the LORAN side. But I know that the LORAN system encoding is intended to be resistant to such propagation situations. I have not made the effort to fully quantify my particular measurements. But I do routinely observe my Austron 2100F showing an almost diurnal change in displayed error when using it as the measurement system against an HP-5061 or Z3801A. Can someone confirm that the E10 to E13 errors are typical of the 2100F? And what ultimate long-term stability have others been able to achieve using LORAN as a reference? Thanks in advance, -Brian, WA1ZMS -----Original Message----- <snip> I have gotten a 4 parts in E13 comparison between the LORAN-C and the GPS disciplined oscillator, at least for a short time, multiple times a day. Most readings are between E10 an E13 comparing the GPS DO and the Loran-C RX. probably bouncing due to the propagation paths and propagation perturbations. <snip> Stan, W1LE FN41sr Cape Cod [EMAIL PROTECTED] wrote: >Hello: > >My different types of equipment (scope, freq cntr, spec analyzer, etc) never seem to be right on the money, so I decided to run them all off a commnon exact 10MHz rubidium source. > >I got an FE-5680A (was on a chopped off ckt board-whcih is apparently part of some motorola system pcb)..I hooked pin 1 to +15V & pins 2 to gns ...but nothing came out any of the other pins?!?? Where is the output? Do I need another cxonnection? I read you might need to apply +5v, but don't want to try unless I know what I'm doing. How do you determine what option your unit has? It looks like about 60 options are possible!! By the way, with my spec analyzer probe nearby I am sniffing the 6.834xx GHz signal-so the Rb is in there doing its thing. > >As a second note, as I read around here, it seems (to my understanding) that the Rb osc is not exact--that in fact it needs calibrated!! Well, I dont't want to cal it --I bought this "atomic clock" to let me cal all of my various xtal oscilators. How on earth shall I cal this thing? If I don't cal, how far off is it?
