Head out to WalMart and find the work shoes section. Find shoes with a solid steel shank. You can buy a pair for less than $25. I did. They are a sorta ugly black running shoe, but they pay for thems
In our case, the tornado didn't actually touch the ground. (In which case, you would be correct -- upward winds) Near the tornado, there are intense winds with a significant horizontal component. (Ai
No. The reason Heathkit thrived for so long was due to the technology. In the early 50's electronic gear was all hand-wired. Buying raw parts packaged as a kit resulted in a substantial savings -- be
I don't know if the shoes I bought meet all your requirements. WalMart had several varieties of work shoes. Many had steel toes. Only a few had steel shanks. The kind I got will bend somewhat from fr
When I poured my Rohn 25 foundation -- I rented a small electric powered mixer from Home Depot. Best $40 I ever spent. I would dump in two 60 lb bags of Sakcrete (not the quick cure stuff), and almos
For the amount of concrete (.7 Yards) and all the minimum fees, it worked out to be a LOT cheaper to mix it myself. If I were pouring a base and three guy points, Ready-Mix might have been a better o
At a recent hamfest, I managed to buy a bundle of mobile antennas for $25. Here's what I found, and some questions I have: Winn-Tenna. 80m, 40m, 15m. These three are similar to HamSticks that go by v
How about more directly from the source: <http://www.aytechnologies.com/> K9AY is Gary Breed, a nice fellow who lives just a few miles from my house. Gary designed the K9AY receiving loops -- a very
Steve, actually, these exist. A local ham has a crank-up that has some sort of flip-over device at the end of each section. It locks the next section to the previous one and takes the strain off the
I thought the advantage of crank-ups is you didn't have to climb them.... For that matter, you should never climb a crank-up. No worries about anything settling then. Bill Coleman, AA4LR, PP-ASEL Mai
I just as soon not fall off of either. There's a great quote from the Motorcycle Safety Foundation materials somewhere. "Q: How fast do you have to be going to receive a fatal injury from a motorcycl
The best thing to do is to vote with your wallet. Don't buy in areas that have CC&Rs. Just say no! Bill Coleman, AA4LR, PP-ASEL Mail: aa4lr@arrl.net Quote: "Not within a thousand years will man ever
I have an R7000 at 8 feet, which I used as my primary antenna for almost 6 years. My observations match Stu's. You can make contacts with this antenna, but there are better choices. Bill Coleman, AA4
Be careful not to crank too fast. When the free end of the cable rises up to the reel, it can cause injury to certain tender parts of the anatomy.... (voice of experience....) Bill Coleman, AA4LR, PP
One. One. Use an FT-240-77. Wind the coax on the core. For a 50 ohm feedpoint, about 6 turns should be adequate for 40m-10m. 8-9 turns for 80m-10m. This isn't the W2DU design, but the W1JR design. Sa
I've been hit in the face before, but that's not the incident I recall so vividly.... Count yourself lucky. Bill Coleman, AA4LR, PP-ASEL Mail: aa4lr@arrl.net Quote: "Not within a thousand years will
43 material has a maximum impedance at around 200 MHz. Perhaps not the best choice for HF -- as you will require more beads. You could use the FB-77-6301. Except you won't need 50 of them. Each is tw
Gosh, you're right, that's why aluminum airplanes are life-rated to only so many flights or years. Right? I'm sure many aircraft owners are still waiting for their 50+ year old airplanes to "work har
The RG-303 is a teflon-insulated coax (and quite stiff, I might add), so you don't have to worry quite so much about center conductor migration as you with with foam-type coax. RG-142 and RG-316 are
