How much was the frequency shift due to the moon's movement? Hans - N2JFS Hi, After two fruitless attempts at moonrise I got EME QSO with myself done during moonset. Here is the video of the best min
Well, if the moon is at the horizon we have a relative movement of the surface of the earth, right? Not enough to make a noticeable shift? Hans - N2JFS Not much as the moons movement is essentially a
What I remember, pulling cables through conduits is that it is very important that the different cables/wires don't twist around as it is pulled in. The wires have to be all parallel to each other. A
What about using the rear axle (or half) of a car (or truck)? At least the strength would be there and some water-proofing too. Hans - N2JFS Hello Roger The scrap aluminium tube I used has a wall thi
Hi Patrick, I think you have some major engineering job in front of you. You can probably use your truck to erect it if you add a "falling derrick", something used in many cases raising a tower. I us
Can't be stressed enough; your problem will be of a more RFI/EMI nature, not anything between the 14 MHz and 2.4 GHz. The usual recommendations set in, keep cables well away from RF sources, keep con
Chuck, I am using a "4G Hotspot" for my internet connection. I live in Halifax, Vermont just on the boarder of Massachusetts. No cable, no DSL only some old telephone cables, probably from G. Bell's
As usual, somebody managed to hack my account. Please disregard anything sent around 11AM today. Sorry for this. Hans - N2JFS --Original Message-- From: Hans Hammarquist <hanslg@aol.com> To: info <in
Another way to go is to use four (4) guy wires instead like what I did. Most important is that it is no longer so important to get the guys evenly spaced, which may help "planting" the guy anchors. H
I made the calculations and, at least in theory, the "bending" momentum on the tower gets lower if you put the guys a little lower. I have climbed it the biggest swing/vibration was between the guy p
Driving several yagis located next to each other and get a predicable result is not that hard. You "just" have to phase them correctly and point them in the direction your resulting wave front is goi
Hi Steve, I think you got the picture. When I put up my tower I used a 3 foot level, construction type. I propped it up with some wood and looked at the level with the tower behind it. I adjusted the
Could that be made without any RFI problems. We are, after all, very close to our antennae up there. Hans - N2JFS Seriously, I've actually given thought to the idea of a line of up the tower and base
Dave, Didn't you forgot the North-seeking, plastic owl? I now have one in my garage, ready to go up. :-) Hans - N2JFS That's what the generator at the top of the tower is for! David Robbins K1TTT e-m
I have picked up a couple of "old type" battery charges at auctions. One has a "starter booster" position that give ~ 50 A @ 12 v. The other positions are 5, 10 and 30 A charging. Works great for my
Really, really nice. What exactly is it you have there and how long did you have to train before you could make that perfect flight. Seems good for inspections of your rigs. Hans - N2JFS Well, except
I am planning to put a box near the top of my tower and use it for various signal wire connections such as rotator cables, antenna switches etc. My idea was to pull a multi-conductor cable between my
What teeth! Grip the cross brace with your teeth? <grin> (and hope your foot doesn't slip) _______________________________________________ _______________________________________________ TowerTalk ma
