[time-nuts] OT - New Mexico travel and the VLA (Food survival)

Milk, or plain Yoghurt will kill the Chilli Pepper fire almost instantly! I forget exactly how, but it's a chemical reaction between some part of the dairy product, and the active part of the chilli spice, neutralising things rather well. It's also how the Indians make a creamy mild curry

After hearing all of you talk about the Black Hole surplus store I did a google search and came up with this neat site: http://eecue.com/log_archive/eecue-log-743-The_Black_Hole___Los_Alamos_Laboratory_Salvage_Yard.html I suspect that J.J. Glass Electronics in Los Angeles from the 50's must

Great site. Amazing what is there. But equally interesting is the age of say the test equipment. Very old. Enjoyed your write up. Thanks On Wed, Mar 24, 2010 at 11:17 AM, Burt I. Weiner b...@att.net wrote: After hearing all of you talk about the Black Hole surplus store I did a google search

I'd guess he probably got the dregs from the lab, stuff that was too old, heavy, or low value that didn't merit shipping very far. New test gear likely went elsewhere. Much of what is in the pics is virtually unsellable and has been so for a decade or two. It's mostly 60s stuff. -John

[time-nuts] GPS antenna setup: how good?

2010-03-24 Thread Hal Murray
How do I tell which of two setups is better? For example, how much does adding a pie pan help? Is there some simple parameter I can look at that tells me an antenna goodness value? If not, what's a reasonable recipe to come up with a number or compare two antennas? What's the appropriate

Hi As always with any simple question - the answer is that depends What are you using for a receiver? Is it sensitivity challenged? A modern receiver will be a *lot* more sensitive than the receiver in an old HP GPSDO. The next layer to that onion is feed line and splitters (or not). All

What kind of GPS receiver are you using ? Most of the Motorola and Garmin can output NEMA data, which is comma limited ASCII. There are data sentences that show the elevation and azimuth of the satellite and signal strength in their arbitrary format. You could extract the once sentence and

Hal, That's a really good question and if anyone can point me to carefully performed measurements already done, I'd appreciate it. It could be antenna A vs. antenna B, or it could be antenna A with vs. w/o ground plane, or choke ring, or radome, or temperature stabilization, etc. For short-term

Hi At least back a while ago, GDOP and TDOP values as reported didn't have quite as strong a correlation as I would have expected them to have. I haven't done that in a while so things may be better with more modern receivers. Bob On Mar 24, 2010, at 7:11 PM, Tom Van Baak wrote: Hal,

Everything the lab can't use anymore goes to salvage. Anything that isn't furniture (computers, scopes, test equipment, etc.) goes to Bentley's Auction House and is auctioned off once a month down in Albuquerque. These auctions include surplus stuff from Sandia, Phillips, and other big labs

If you are running a Thunderbolt, the beta 3.0 version of Lady Heather has a couple of tools in the S)urvey menu that might come in handy. First is the 3)D fix mode. This will put the receiver into 3D fix mode and plot the results. The wider the resulting dispersion of data points, the

If I understand the choke ring antenna it is to remove signals propagating across the ground plane. Now if there was a very lossy layer on the ground plane any signals propagating across it would be attenuated. For instance, if you find a plastic that melts in your microwave, a sheet of that
