I use a strong rope on each of the element ends and tied with a "timber hitch" knot. One rope goes to a fixed support, the other to a come-a-long anchored to another fixed support. If you need more f
Bill, IF all else fails, try the Linda Hall Technical Library in Kansas City, MO... they have a reference service that may help you at reasonable cost. Also try White Industries in Bates City, MO. Th
Hi TT'ers, Working on a pushpull receiving amp that uses binocular cores of 43 material in its design. Is there any reason toroids, of say, a 43 mix or MN8CX core could not be used as well with the s
Hi Bob, All you have to do is tape a thin piece of paper to the bottom, then rub the paper over the holes with the "side" of a lead pencil point. Your pattern will then be transferred to the paper. 7
Water will indeed accumulate and cause all kinds of problems including a nasty mold! Sometime after I installed a 200 foot run of pipe I noticed an foul odor coming out of it at the shack end. I tri
Yep, sure does get tangled...I think I mentioned this before on TT... Install some smaller thinned-walled PVC pipe inside the larger to run various cable in. The thin-walled is cheap, comes in 10 or

We all have our own way of doing things and levels of "comfort"....:) To toss out my two cents worth here's what I do and feel comfortable with: I use TWO belts, one is the standard leather belt and
Hi Gents, My 259B needs some "minor" calibration for the "R" readings. At a known good "pure" resistive load of 50 ohms, "R" reads 46. I understand, per some TT threads that a precision test fixture
You are lucky you didn't disturb them during their "happy hour"! hi hi In warm WX you can pull a "night raid" on them with "wasp and hornet killer" when all of them are home, but the best and safest
The problem is with a "ground loop"...control lead grounded at the tower AND in the shack...remove the field circuit ground connections inside the control box and let it "float"...let it be grounded
Have you tried MFJ? I purchased a set of trap caps from them some time ago...had them in stock when they were just setting up the Hy-Gain supplies. Other than that try a "good" hardware store. 73, Ch
Hi gents, My barbershop comments... :) I would think that if there were say, 3 guys running to the same anchor, that one would want to line up the anchor with the "middle" guy wire. If there are two
Interesting threads out there on the guy rod angles... First of all one should DO what the Rohn book says to do; that's most important. But I'm guessing here that most tower installations of the amat
Throwing in my 2 cents worth here...since this subject would cover just about everything that goes on here: It seems to me that subject of alleged "harmful" advice has already been covered in the cou
Hi TTers, I would like to test some homebrew parallel resonant traps for heating and breakdown without transmitting on the air with full legal power and without an elaborate setup. The two types of t

Hi Frank, This is what I did to make a *USEFUL* "dip" circuit for my MFJ 259-B. Of course it should work with other RF generators too, but the MFJ (or equivalent) is hard to beat for convenience and
Tom, Actually, the 259B is *NOT* used as a grid dip meter in this application...the external meter is the "dip" indicator and it really is quite sensitive. Perhaps I didn't make that clear. BTW, MFJ
