Well, I agree 100% that tennis shoes are not the preferred footwear for tower climbing. Having said that, I have a pair of Redwing boots with steel arch inserts that work very well. However, I seldom
I am in the process of upgrading my grounding systems. I have the new book on order from ARRL and a couple of retired power company engineers to advise. I won't go into details, but I have a question
I have one of these which I use to check SWR and measure component values. I love it. I know it is capable of doing more. I just haven't had a need to use it any other way. What I am wondering is, wi
Thanks to all. I will take the three frequency data and send it to Dave (Thanks!) I have been driving all day and I need to take a nap. I will get to it soon. I promise. Thanks again, Dave, K4TO ____
I have a new, never used (but scratched in shipping) K9AY control box if anyone is interested. Dave, K4TO _______________________________________________ _____________________________________________
I have followed this thread with interest. I am surprised that nobody seems to have considered the following: Several months ago I was given a link to a couple of papers by K5IU and someone else, who
Don't forget Les Moxon's "HF Antennas For All Locations". Dave, K4TO _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@c
Googling did not yield the desired result. MFJ doesn't have it on their website. I need a schematic diagram for an MFJ-2145, 13.6 volt regulated power supply. Any help would be welcome. Thanks, Dave,
Thanks to all for the help. I have the schematic. I think we can consider this task as complete. 73, Dave, K4TO _______________________________________________ _______________________________________
Has anyone had any experience with *cocoaNEC 2.0 ??* I have just found a reference to it and was wondering if it is any good? 73, Dave, K4TO _______________________________________________ __________
I've hesitated to chime in here because I thought the problem was being discussed very well and perhaps I don't have anything to add. But I do. Kwajalein, Marshall Islands. The pileups were big and w
My six element 6M LFA is showing a high SWR and severe loss of receive signal. This happened this afternoon as I was working the band with 500 watts from my KPA500. To this point, the antenna was ver
I just checked the coax I used. It has the stranded center conductor. I can't find the part number on it. I would hve to find the invoice. But it is the mil spec teflon/silver coax. K4TO The antenna
Good afternoon, A memory has been stirred by the discussion on ropes for hand hauling. Rather than hijack the thread, I will start this. 33 years ago, when I moved to this location, I put up three to
The Rohn manual will give you all the base and anchor data. If you plan to spread your antennas over the complete height of the tower, you should put the anchors out 175 feet from the base to give cl
There is a soldering iron attachment available to screw on to a propane bottle. You can find them at the box stores. I have used one for years with good results. They are probably pricey, as is every
I don't know the conductive properties of that Permatex mixture. Since one of the primary purposes of the Penetrox-type mixtures is to enhance conductivity, I wouldn't use anything that wasn't design
FYI. MPJA.com has linear, ten turn, 10K potentiometers for $3.49. This is the standard position potentiometer on the Prosystel rotators. Anyone who has replaced one of these knows they cost upwards o
I got an email, allegedly from this list owner saying I had too many bounces and to reconfirm my membership or I would be dropped. It had links enclosed that appeared to take me to the registration p
