It's called a "come along". A Cum-a long sounds rather dirty. Take it from someone whose sense of humor was fully developed by the age of 14. Oh, I guess I have to add these: 8-) 8-) 8-) 8-) 8-) 8-)
Enough heat will surely separate rusted together fasteners. My worry would be that heating to the cherry-red stage (what I've observed is usually necessary in an automotive context) negates any harde

The one thing I would point out is that while manual labor is cheap - maybe $10/hour - the contractors real costs to do your job are opportunity costs. If the time required to dig your hole by hand m
They're both divisions of Amphenol. Al AB2ZY Thanks all for the answers No doubt now. http://www.amphenolrf.com/ is what I am looking for. Thanks, Jorge CX6VM/CW5W --Mensaje original-- De: TowerTalk
The MFJ window feed throughs work fine, proviced you're not dealing with casement windows. I used one when we were selling a house after I had patched up the hole in the wall I had used for the job b
They provide you with a piece of self-adhesive foam that does the trick. Not the most elegant solution, but it is effective. Al AB2ZY Fred I have looked at the MFJ window panels and can't figure out
This observation is spot on. If you assume (like the misanthrope I am) that a) people are, on average, stupid and b) will never admit when they make a mistake, that allows you to discount virtually a

It depends on whether and how the receiving mail server is configured to deal with incoming email. Note that I'm assuming the problem is people with (e.g.) yahoo.com addresses receiving bounce messag
Regardless of the specific instrument, ANY digital measurement system will require some amount of time to sample the transducer output. The time required depends on the resolution of the transducer,
You're missing a time constant there. 2.5 mph per revoution per ???? A single revolution or a single pulse has a measurement uncertainty of +/- 12.5 % with 8 ppr. So if you're going to measure veloc
There's hot wire anemometers which can have very fast response times (milliseconds or less), but which require a bit more calibration, and are sensitive to ambient temperature. This, for those that d
I don't think it's misleading, but you'd have to look at my prior post. If you're going for a "fast" measurement technique, you can measure the time between two pulses. If you do that, the absolute p
I'm not going to belabor the point. Wind speed is derived by measuring the change in rotational position divided by time. The shorter the sampling interval (time), the lower the measurement accuracy.
This is the key thing that misses the entire point. It's not the accuracy of the time measurement that's the issue. It is the uncertainty of when position transitions are crossed. With either electr
