Re: [time-nuts] GPS Distribution amplifier

A 50nF Cap should do just fine. Little smaller/bigger probably ok as well. Size? A small ceramic should be fine. After all we are not expecting KW. Hmmm... I wonder what the power output of a GPS sat is? Is that classified? Even if it is, if I know it's height I can probably figure it out. Estima

Re: [time-nuts] GPS Distribution amplifier

I did eventually get an SMC connector. However, I may take a look at converting it later, to eliminate the extra 5V supply. Did you have to remove the circuit board from the metal housing to make the mod? If so, that would make it much more difficult. > The PCB is the same for both models. > >

[time-nuts] new HP GPS amplifiers and antennas

I have a few absolutely brand new HP GPS distribution amplifiers and also some antennas. I was going to take them to the EME conference in Germany next week. I will include the decriptions below but won't send the photos to the entire list. If you want photos, send me an email. Prices I set are rea

[time-nuts] fyi: plotter.exe works with wine

For all the linux fans out there: DF6JB's plotter.exe version 20060801 appears to work with the current version of wine which is shipped with CrossOver Office. I would assume it would work with other versions of wine as well. I don't have any data to process at the moment, so I can't test it muc

Re: [time-nuts] GPS Distribution amplifier

I gotta say this about eBay, if you wait long enough you will get what you want. Specifically, I bought 2, 8-way splitters for $100.00 each from The Tucker store. Both had the power connector which was a SMC connector (I believe). Takes 5Volts to make it run even though the markings indicate that

Guys, Maybe it would be better to call it the "leading" edge? I have actually sent out a couple of our SynPaQ receivers with the 1PPS jumper in the "inverted" position per customer request. There always have to be a couple of oddballs. Randy -Original Message- From: [EMAIL PROTECTED

Re: [time-nuts] Falling Edge Error

If i'm not wrong, virtually ALL GPS modules have their timing standardized on the RISING edge and do NOT guarantee anything about the falling edge. Glenn's measurements confirm that fact... Ideally, to get sure the users will use the rising edge, that signal shall be a sawtooth!!! (or simpler: a r

Hi, USB is no use for any time critical application. We put considerable effort into using it for an industrial automation type I/O application a few years ago and it was a waste of time and effort. The protocols are non-deterministic and the data is packetised so timing is inconsistent. There are
