Jan- I would like to suggest that you consider using the program "Geoclock" with the Ham option. This program will come with a large collection of maps at different levels of detail, and has one grea
After some of my comments and reporting of my re-setup of a R25 foldover, Jeff, W7ID, sent me the following: next spring. I would appreciate the information that you have found on the winch and cable
Mr. Dimitry I was an aerospace Engineer for many years , and, to my sorrow, I wrote a lot of "proposals", so I know how to spot a lack of Precision (a mild term for it !) in product description. Howe
Gentlemen: At about the time I joined this reflector, there had been a thread about refurbishing rotors, and in certain changes that were desireable. The thread had mostly passed before I was here, a

In the beginning, there needs to be a word- like "THANKS" to Kurt, and the people like him, who are truly professions, but share so much with us. then- I still have a quibble with acceptability of th
I am putting up a new (to me) tower, and am in the mixed 'plan-ahead' - 'doit' mode. What this means is that I have decided on the basing, dug a hole, and cast some concrete. I decided not to ground
As a part of a recent used tower deal, I got a thrust bearing, a TB-3. As received, it could not be moved, because the bearings (balls) had made indentations in both the inner and outer races. As an
I really hit the jackpot with my "refurbish" question- Lots of very good commentary, and some advice. However, I feel the need to make a few comments myself, with regard to the "force" situation that
Bob- I am in the process of installing a much smaller tower than the one you are, but I, too am faced with having unequal levels for the end-points. My approach was to locate the ones that were nearl
Terry- Note that several have suggested heat-fusing the ends. I agree, but there is a simple way to keep from having a big BLOB when you do it. Wrap ordinary clear plastic tape around the rope, just
The screw-in anchors I have are an over-kill, compared to the ones sold for the Rohn 25, and have a forged eye desigbed to rtake three cables. (at least that's how they look. They are 60 inches long,
Bob- if our esteemed list moderator doesn't beat me to it- go to : www.championradio.com. and order the Rohn Catalog. It has everything you need. I just got a 48' version of the Fold-over- used, and
Why is it that people that can copy an s3 signal at 35 wpm and get it ALL right, miss the key point in this thread from W4RNL? Every reference to his excellent work on this subject has apparently mis
Pete- I acquired an ATB-34 as a part of a tower deal, and did some research- including getting a copy of the assembly manual from a fellow TT er. As far as I can tell, the ATB-34 is just an early ver
I have heard you mention doing everything except getting rid of that tuned length line. I would reset the elements to the mfg specs, and get another line (NOT the same length) and try again. Every go
1.- his entire set of comments were in the context of the actions that take place when line stretches. 2. when lines stretch, the longer lines stretch more than the shorter ones. (ie, the top guy gro
As a part of a package deal, I have just acquired a beam of unknown origin. It is apparently about 18 years old, judging from dates on other things that were with it, (the rotor manual has a 1980 dat
