Re: Tower suggestions....

> I'm considering mounting the tower on my deck which is made from 2" x 6" > decking with 2" x 8" rafters on 24" centers. > <snip> > Does this sound feasible or am I gambling? Rod - Let me ask you two+ questions: 1. Is this configuration included in any installation guidance issued by Rohn? 2. Are you required to get a building permit? If so, what documentation are you required to provide in terms of plans, engineering drawings, and loads analysis? If the answer to #1 is yes, then you're in the clear. Follow Rohn's directions and you're fine. If the answer to #1 is no, and #2 is yes, you might find that you may have to provide details that would PROVE that your installation is safe. (This is in contrast to an installation that exactly matches a recommended Rohn configuration, where you could reuse their canned analysis for permit purposes.) And unless you are a professional engineer (or you know one who will work pro bono), your savings of two sections of tower may pale in comparison to the cost of a PE's time to do the required analysis. And even if the answer to both questions is no, it would probably STILL be a good idea to get someone knowledgeable to review the analysis and see if it makes sense. You might find someone on this list that could do that, but I'm not sure I'd "gamble" (your word) my house on a guess or back-of-the-envelope calculation. Good luck. 73, Steve W3HF P.S. I'm NOT a mechanical engineer. But I did take mechanics classes when I got my EE degree 28 years ago, and I did pass the first half of the NY state PE exam back then. And I personally don't think that 2x6 decking on 24" centers would be enough to safely mount the base of a 20-30 foot tower made of Rohn 45G. After all, any lateral loads would be braced by only a few 16d nails or 3" screws, the ones that hold the decking to the joists. (They're called rafters in a roof, but joists in a floor.) But I have NOT done the calculations, and would welcome the inputs of someone who is more qualified to analyze this.

WD9EWK from DM34/DM44, 13 May 2007
by Patrick STODDARD (WD9EWK/VA7EWK) 17 May '07

17 May '07

Hi! After a few days, I have been able to sit down and download pictures from my camera, audio from my recorder, make some MP3 files of those audio recordings, and log my contacts from that Sunday trip I just took to northern Arizona. It was a fun drive, making 24 contacts from 3 different locations during 5 different passes (2 on AO-51, 2 on SO-50, 1 on AO-27) throughout the day. First stop, DM34we (34.184433 N 112.134783 W, 3400 feet/1036m elevation) After leaving home at 0645 local (1345 UTC), I drove north to a freeway rest area on the edge of a valley about 50 miles/80km north of Phoenix on the I-17 freeway. This rest area, at Sunset Point, has a good view of the sky in all directions, and was about 12 miles/20km north of the DM33/DM34 boundary so I could start my operating from DM34. You can see a map with photo from Google Maps of this location at: http://maps.google.com/maps?f=q&hl=en&q=34.184433333+n+\ 112.134783333+w&ie=UTF8&ll=34.195617,-112.116938&spn=\ 0.050618,0.065489&t=h&z=14&om=0 I parked at the south end of the parking lot, so the back of my wife's truck was pointing northeast - perfect for the upcoming SO-50 pass. The pass, at 1444-1458 UTC, was a nice one to start with. It had a maximum elevation of 38 degrees, going from north to southeast, and I hoped that would bring more than 1 or 2 contacts to start the morning. It did - 5 contacts (W6ZQ in Arizona, N5AFV in Texas, and 3 Mexican stations - XE2HWB, XE2MWY, XE2WY). Once the pass ended, I packed up my stuff and drove about 25 miles/40km further north for more fun. DM34xm/DM44am (34.51875 N 112.0 W, 4455 feet/1358m elevation) This was the area I had identified previously as a good spot I could drive to and operate from both of these grids at once. It was a little more than 1/2 mile/1km west of the I-17 freeway, and north of Arizona route 169, just inside the boundary of the Prescott National Forest. For those not familiar with Arizona, a forest at this elevation has few trees. I was able to follow a dirt track north from route 169 that turned east and let me park at this spot away from the highways and have a good view of the sky. A map with photo of this location is at: http://maps.google.com/maps?f=q&hl=en&q=34.51875+n+\ 112.0+w&ie=UTF8&ll=34.518898,-111.9942&spn=\ 0.025211,0.032744&t=h&z=15&om=0 Since I didn't have plans for lunch until 2100 UTC, I knew I could spend the morning playing radio on my way to lunch. I arrived at this spot about 20 minutes before the first AO-51 pass I could work at 1541-1556 UTC, confirmed the location with my GPS receiver and took a couple of photos of the display showing 112 degrees West exactly, and set up my equipment. The first AO-51 pass, toward my east, was the busiest pass of the 5 I worked. This was also the pass with the highest elevation, at 62 degrees. I made contacts with 9 USA stations and 2 Mexican stations during this pass. All of those contacts were in the first half of the 15-minute pass, and I did not hear any other stations come on for the last half. Oh well... it was fun to get on and help others put these grids into their satellite logs. About 30 minutes later, I had an SO-50 pass that went to the west of me between 1625 and 1638 UTC. It was a 20-degree pass, and I figured that there would be only a few showing up on there. Unfortunately, I was right - Mark WA8SME in California and Bernardo XE2HWB in southern Baja California were the only 2 I heard during the entire pass. I worked them both, then waited for the final AO-51 pass of the morning I'd work from this location. When AO-51 returned for a pass at 1721-1733 UTC, it was only up at 14 degrees maximum elevation. Not an impossible pass to work, but one that would probably have few stations show up. After a couple of minutes, I work Dino VE7XDT near Vancouver. Dino was demonstrating satellite operating at a swap meet, and I was happy to say "hello" to him and his group there. I made contacts with 4 more stations in Idaho, California, and Washington state to complete this pass. After these passes, I drove across to Payson - a small city about 90 miles/145km northeast of Phoenix - for lunch. After lunch, I saw that I had time to work an AO-27 pass on my drive back to Phoenix. This pass was a "bonus", as I had not previously announced any plans to work afternoon passes on this day. DM44ha (34.0347 N 111.365866667 W, 3196 feet/974m elevation) This location was another highway rest area, at the junction of two Arizona state routes (87 and 188) about 15 miles/25km south of Payson on the way back to Phoenix. I had quickly driven to the DM43/DM44 boundary, but there were too many mountains to the west so close to that spot I decided not to try working AO-27 from there. This rest area is about 3 miles/5km north of the DM43/DM44 boundary, but with a better view of the western sky. You may see a map with aerial photo of the location at: http://maps.google.com/maps?f=q&hl=en&q=34.0347+n+\ 111.365866667+w&ie=UTF8&t=h&z=13&om=0 Along with running my PREDICT program, I used the Java applet from the AO-27 web site http://www.ao27.org/ to know the approximate time the AO-27 repeater would switch on for the pass I could work. The start time was 2315 UTC, and I was ready to go. Or so I thought. I knew that the AO-27 timer is not the most accurate timepiece. I expected that it would turn the repeater on a little early, but I think I missed the first 30 seconds. There were some high moutains southwest of me, and I think I might not have been pointing at the satellite accurately. Once I heard Mark WA8SME on there, I called him and made another contact with him. Nobody else showed up during the pass, even when we would take breaks to invite others to join, so we chatted until the repeater switched off at 2322 UTC. Only one contact during the pass, but better than nothing. Recap Overall, I made a total of 24 contacts on 5 different passes. I worked stations in 10 US states, 1 Canadian province, 4 Mexican states, and a total of 18 grids. I made 7 contacts on 2 SO-50 passes, 16 contacts on 2 AO-51 passes, and 1 contact on the AO-27 pass I worked later in the day. Maybe not a large number of contacts, but 11 on one AO-51 pass was pretty good. With the hot weather in the deserts of central and southern Arizona during the summertime, I hope to be able to repeat trips like this and possibly to some other grids further north. I have posted photos from the first two stops I made, along with MP3 recordings of the passes I worked from those locations, on some free web space I have. You can find those files at: http://www.geocities.com/xe2wd9ewk/20070513-DM34_DM44/ Since this is free web space, Geocities will enforce hourly bandwidth restrictions. If you have difficulties in accessing those MP3s or photos, please e-mail me directly and I would be happy to send you any of those files. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/
