Hmm, that link gives me a different program. Try this one: http://public.npr.org/anon.npr-mp3/npr/totn/2010/09/20100924_totn_01.mp3?dl=1 - Chad. On Fri, Sep 24, 2010 at 12:17 PM, Oz-in-DFW li...@ozindfw.net wrote: The recorded version is here:

To be more precise, the guest was Tom O'Brien, Chief of the NIST Time and Frequency Division. In any case, I should have known the message would not propagate out the list in time for people to catch the live broadcast. Surely there will be a rebroadcast and/or webcast available soon, though...

Re: [time-nuts] GPS from a window seat

Hi Bill, I've done this a few times, with mixed success, using an AMOD AGL3080 GPS data logger. I managed to capture an entire flight from HKG to SFO. That was from a South facing window seat. One thing to watch out for is getting a good solid lock on the ground (e.g. in the boarding lounge)

Matt, I would be very interested in the python code. I got a good deal on the E2050A, and though I haven't set it up yet, I imagine it works the same as the E5810A, just without the DHCP and web config features. Adrian, I don't have the full manual, but I emailed you the Installation and

Re: [time-nuts] adjustable gain/offset amplifiers

2009-07-24 Thread Chad Simpson
Hi Jim, Take a look at the LeCroy DA1855A... I think that might be just what you need. 100MHz BW, precision offset generator, gain settings up to 10x (or is it 100x? ... been a while since I've used one). You'll need 1x probes to get the max gain though. - Chad. On Fri, Jul 24, 2009 at

Good points... and pretty much in line with my thinking. Based on the comments here, I'm strongly leaning toward the LAN version now. I'll definitely have a closer look at the KE5FX toolkit, there are some very interesting applications there. Thanks everyone for your input. Looks like I have

[time-nuts] Prologix GPIB-USB vs. GPIB-LAN

2009-07-04 Thread Chad Simpson
Hello all, this is my first post to the list... Like many of you, over time I've acquired enough test equipment with the GPIB interface that I'm wanting to make use of it. I have narrowed the choice down to one of the Prologix devices (GPIB-USB or GPIB-LAN), but I haven't found much information
