Hi all, Is there a book, or some simple software that can calculate the forces on the tower, the anchors and the tram cable when tramming up an antenna? I've seen rules of thumb for the forces on the
Perfect!! Exactly what I was looking for. Thanks much. 73, doug http://www.k1ttt.net/technote/tram.html look at the 3 page scanned article at the top of the page. David Robbins K1TTT e-mail: mailto:k
Note that there was a QST article, February 2000, page 46 about a similar setup. They show a flexible reducing drain pipe adapter, and I've seen somewhere mention of using the rubber part of a toilet
And to follow up my own posting, there's also an article in the 6th volume of the ARRL Antenna Compendium on doing the same thing. 73, doug Note that there was a QST article, February 2000, page 46 a

Yep, many of people filter our email, and mail to lists gets put into a mailbox with a lower personal priority. If the response should really go to both, then I send to both, such as when I answer a
Just to add a bit to the threaded rod (or All-Thread) discussion- I used stainless steel threaded rod, and had to remember to use anti-seize on everything. I had some galling even from the first tria
Err, they've got USB to SDR-1000 parallel port adapters for sale on the FlexRadio web site, $59. This one is designed for the purpose, 73, doug OTOH, if you know of a suitable USB parallel interface
Sure, all possible obstacles, but the lack of a parallel port for a USB-only computer isn't one. 73, doug Indeed.. but you're still faced with the port enumeration problem (plug 4 of those into a hub
I'd suggest McMaster-Carr, www.mcmaster.com for everything you need. They're often cheaper then anyplace else (BUT NOT ALWAYS), and have an incredible selection, and technical information to go with.
I've run sprinkler tubing under a sidewalk using a piece of copper tubing as a water lance. I dug the trenches up to the walk on both sides, put a garden hose fitting on the tubing, and let running w

This is pretty trivial, but my brain is full right now: Has anyone a quick cookbook recipe for converting the (burned out) lamp in a HAM-IV rotator control box to LED's? 73, doug ____________________

The Harbor Freight unit listing says it's SDS (no Plus mentioned), and I've been unable to locate a ground rod driver for that type, but have found them for spline and SDS Max. Does anyone actually k
