[VHFcontesting] September VHF contest

[nosigma at aol.com]

Sean,


DONT USE fence post top rail or conduit tubing.  I did the fence post top rail and it was stupid heavy, lousy heat treat (not stiff) and a major PIA to raise and lower.  My fold over is 16 feet with two folding 6 foot cross arms (running four 12ft beams VV) and its way to much to handle by hand but a heck of a lot better than steel.  I use a gin pole and a winch to raise and lower.  Safe and easy.  Be super careful that it cant rotate while being raise because in a high wind when folded over it will spin off to the side.  I darn near killed myself last November during testing up on a mountain top when we went from still air to 50mph+ while raising the mast.  My mast is now laterally guyed while going up, good to 100mph.  See my QRZ page for fab details.  Just make the mast high enough to get the right launch angle from the antenna's.  You ability to be mobile and drive to a stupid high location gives an 3,000 or 5,000 foot high tower.


If you can go crank up vertical or pneumatic vertical you will be a lot happier than using  a fold over.  I love my station but I went fold over because I could do it on the cheap with fab skills in place of money that I put into radio's.

We use some thicker EMT, it's usually made of steel. We're looking at tiltover, drive over mast holders and going with 2 lengths, the masts we'reusing are only 10' lengths so it doesn't get us up all that high. It's waytoo heavy, particularly with the beams, to do it on 2 sections. Carefulloading up the thinner stuff too high, it can buckle.We use one of the Ukranian 222MHz transverters (http://transverters-store.com/). Inexpensive, 29MHz IF, about 8W out. It'sslightly off frequency, but by a predictable amount. We ended up getting aRadio Shack HTX-10 to drive it, there was too much of a risk of "oopsing"and putting 100W from the IC-7000 we use on that station into thetransverter and letting the smoke out. For an antenna, we picked up onefrom Directive Systems.I've got a pair of 100Ah deep cycle batteries in the car during the rove.We have 2 operators in the car, and are running 100W on 6 (IC-7000) and 2(IC-746) with assorted extra current draw from the 70cm (FT-790RII) and1.25 (HTX-10+xverter) radios. If we're both transmitting it's probablysomewhere around 45A draw, a little much for a single battery to be happywith. I've thought about adding a solar panel, unsure if it's worth thecost and additional hassle of setup in our situation. It may be more usefulif you're sitting for longer or have shorter drives.It really is never ending. The handy places with high elevation are closedin Winter in New England, so for January we're looking at a full run-n-gunsetup so that we just drive forever instead of stopping and setting upbeams. This is of course more stuff. Then we need to implement a pile ofother changes for the next September contest (June is a no-go for us,unfortunately).Maybe I'll get some equipment on the air for the 2m sprint next week, butunlikely. I do need to test something with our mobile setup, so maybe.Good luck and hope to make a contact someday,Sean WA1TEOn Tue, Sep 12, 2017 at 3:50 PM Nick Pick <nicolasgagnon at hotmail.fr> wrote:> Hi Sean, yes still thinking on how to improve, already know that I want a> second battery and probably a solar panel because there's not a lot of time> to operate on a saturday, and dismounting everyting when it's dark is a> pain in the lower region and probably focus on operating on sunday the next> year, exept january, I will be on our local mountain here so can go> saturday and sunday...> For mast, I use 2x 10' of electrical metal tubing (forget in what material> is made) that I buy for 15$ each at Home Depot but with antennas, the thing> is too heavy and difficult to raise alone, I was lucky to have someone> doing a sota to help me raise it!> Will try to cut 1 tube at 5 feet and try to raise it alone, perhaps next> monday for the 144MHz sprints, but not sure yet...
