[time-nuts] 5370B on eBay

Two of those, with similar symptoms of bad sockets, otherwise similar appearance, sold within an hour of each other, one for about $100 and the other for $250. I guess a number of people got pissed after missing on the first one? eBay never ceases to amaze me! Didier KO4BB

Re: [time-nuts] 5370B on eBay

Assuming you're talking about the ones sold by sierrametals, I think I mentioned a few posts ago (2/13 at 1950 PST) that the problem with an earlier one he sold was simply that its reference switch was set to EXT. That appeared to be true of the second one as well. The earlier one was pretty

John, One was sold by sierrametals (went for $250), the other by electronicswest (went for $104) I remember your posting but did not associate it with these items. I bid on both, just in case since they were still at $20 an hour before close, but I was not even close to final price, in either

Bruce, Thanks a lot, I will wait until I get the unit and find out exactly which model it is, then I'll let you know what the next questions will be :-) All applications I have seen referenced when searching google for carrier phase tracking had to do with surveying or precise tracking. I

Re: [time-nuts] 5370B on eBay, carrier phase tracking GPS receiver

Brooke Clarke wrote: Hi Didier: Many GPS receivers output carrier phase data but it's usually used in post processing to get survey grade position accuracy. Since the code phase position accuracy is larger than a wavelength the receiver does not know how many integer wavelengths to add.

Re: [time-nuts] 5370B on eBay, carrier phase tracking GPS receiver

Brooke, I read about the uncertainty of absolute position because the carrier phase data has no absolute reference, but that still gives a very precise relative position (and speed) information. The point is that for timing, absolute position information is probably unnecessary. The benefit
