Great catch! It's so very often these little things that slip past us, and that we seem to learn and relearn and relearn, that cause such grief! I'm pretty sure that by the time such a problem crops
FYI re: the sealing of connectors, a link to some excellent info from seven years ago is at http://www.qsl.net/n9zia/wireless/sealing_andrews_connectors.html Jim, W3WV _______________________________
". . . insensitive bigotry." Really? Hard as it may be to believe, a few hundred-foot metal poles with giant spiderwebs on top are not necessarily things of great beauty to all reasonable human being
Several years ago, I was quite fortunate to attend a seminar about lightning protection presented by one of GE's lightning experts. He had worked for their mobile radio group in Lynchburg, VA. Unfort
Thanks for the info, Tim. I did some searching and see that there are some items about your article in the TT archives--go there and do a search for K3LR and W0IYH "choke" baluns in the feedline syst
Thanks for the info, Tim. I was hoping you might remember some of the details, such as bead nomenclature. 48 inches! What a monster! Maybe someone out there has access to the original article and can
What am I missing here--I don't understand the difference between a "balun" (at least a 1:1 balun) and a "choke." Possibly K9MI is referring to a 4:1 (or something else other than 1:1) balun? Aren't
Thanks for the response, Steve. Yes, I know what the function of a balun is, and have read (and re-read several times over the years) the books you probably are referring to, namely those by Jerry Se
This sure brought back an old memory that caused me to chuckle out loud. About 25 years ago, my brother (also a ham) and I tried to jury-rig the "draw knife" idea that Jim mentions. My brother had ju
Sorry, OJ, not quite "END OF THREAD!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!" Just to make it "official," if and when *I* die because of something related to ham radio, I ask that if there is
See--someone COULD effectively rebut the original post in a non-attacking and civil way. Oh, if only we all (including me) could/would do this. Thanks, Ward. 73 to all-- Jim, W3WV ___________________
I also use PVC pipe. Outside, I have a 90-degree elbow (open end pointed down) stuffed with foam rubber. If your pipe will be below grade, this obviously is not the way to go! 73 Jim, W3WV __________
Hello, Van-- Keep in mind that the SWR meter is designed to operate with a given impedance--almost certainly 50 ohms; it will produce erroneous readings when connected to other impedances (input or o
Someone asked this earlier, but I still haven't seen the answer: What is the _purpose_ of the ground? If it's for power-line/safety, the braid probably will be fine. But if one wants an RF ground, br
The "Rough Science" series has been shown several times on one of the PBS stations here in the Washington, DC, area--some really good stuff! The basic format was that the scientists were given a chal
Sorry, Joe, but you're wrong here. Warned or not, "R" rated indeed is inappropriate for this site. The insults about "grow up" and "Falwell" also are inappropriate. Jim, W3WV ________________________
It seems to have been missed by many that the point is not whether the picture is "pornographic" or whether someone is offended or whether someone is prudish or whether someone clicked on a link that
Pete, you might take a look at the type of helmets used by rock climbers--they are designed to protect against (among other things) falling rocks, so they should work for falling bolts, too. One high
Several days ago, I mentioned that I had seen the Petzl "Ecrin Roc" helmet at a good price. I finally remembered where, and picked up mine, along with much other climbing gear just today. If you're i
That was nice of you to express your thoughts about Bill, Doc. However, your inclusion of political comments were improper, yet give me permission to say that President Bush is the liar and puppet. H
