Take a look at W7YRV's site on qrz.com! It really made me think about putting up towers.

The quad project just didn't turn out good I'm sorry to say and after about 35 or so major problems to resolve I gave up. Between the winch problems, making the crankup work, and then Necwire2 just not coming close to what the 5 band quad was reading, it was too much. Probably took onmore than I could handleand I sure missed getting on the air.
I've put the steppir back up on the new crankup tower and it sure is nice not to fight SWR issues and to have an antenna that I know works well. I have resolved the winch problems. The new Ramsey RE8000 worm gear winch works well. It did require a custom mount but it is a beast of power and I just got to remember not run it too long. Take short up and down runs about 20 seconds or less and make sure the winch doesn't get too hot (low duty cycle). No hand winch could be used to raise this heavy of tower the way I have it setup. Even with the 40:1 ratio worm gear hand winch it took about 80 or more pounds to crank it and that was just an inch or so per crank revolution. And adding a second pulley in a doubled line setup didn't help. 900 plus pounds of tower and antenna requires a winch like the 8000 pound Ramsey RE8000 worm gear 12 volt winch. A bonus would be to parallel two marine batteries for more current capability but I haven't had to do that yet. Leasons learned the hard way!
The three pictures above are a closeup of the steppir and GP6 (2mtr/440), the Ramsey RE8000 winch with it's custom mount, and a longer distance picture of the tower and antenna along with the house and my toy (el camino). Well, you could almost see the house if it wasn't for my favorite tree.
The two pictures below are of the Steppir at 70' (about 21.5 meters) high. I can still go up another 10' or so and may do that come contest season. There are three guys on the top section that are 1/4 wavelength 80 meter slopers but only the SW sloper seems to work right now. You can also see the second pulley up on the tower to devide the load in half between the two lines. Also the 'X' frame I use to strengthen the tower when I lay it over.
Above is picture of the tower while I was building the two section crankup affair. Note the rotor is below the top of the lower rohn 45 sections. The u-bolts on the rotor plate dragged and would catch on the outside section bolts so I no longer lower the upper section into the lower section where the rotor plate is. That leaves about 9 foot of rohn 25 tower above the top of the lower rohn 45 sections. Note that this picture is prior to my adding a second pulley on the tower deviding the load. But it does give a good look at the customized tower setup.
Below is the 5 band 20-10 meter, 30' boom quad array I used to have. 14-15 square foot that I changed out for the Steppir 3 element 20-6 meter in 2006. If anyone wants the dementions I developed on NECWIRES 2.0 for the big quad array I can send a file over email to them. I worked several months on my old computer developing the quad dementions for each band and it seemed to work out well. My latest quad design of 4 elements on 20/17/15, 7 elements on 12/10, and a 2 elment folded yagi for 40 meters proved to have major issues with 12, 15 and 40. I'm sorry to say it but Necwires 2.0 failed me (or I failed it). I'm sure it was due to the combining of all the bands togethermaybe LBCebik was right about complications with multiband quads. I have seen such issues with 10 and 12 before and did manage to resolve it on the older 30' boom quad you see below. If I try building another quad array it will start out as a single band (20 mtrs) and after that works I will add a band at a time .maybe. That is a hard process to do since I have to rotate the spider/spreaders to string on the elements for each band. Hard process with overhear trussing that has to be disconnected.
I've had a picture up in my shack for years of a 1965 red El Camino that I've always wanted but never thought I would be able to afford it. Well you might say a miracle happened and I got my 'Dream Car', a red 1965 El Camino with 350 cu. in, automatic, black interior bench seat, and loud pipes. It really came like a bolt out of the blue, completely unexpected, but I did have that picture up in my shack for years. Maybe I should put a picture of a big multi-element quad on a 100' tower up in my shack, ya' think?
Below are some pictures from my messy shack.

Lineup on antennas as of 4/07/2014
1. 3 element 20-6 meter Steppir at 75' now (23.0 meters) with a 16' boom. After having a major issue with water in the coax I brought down the tower, replaced the bad coax, added another 80 meter sloper and four 40 meter slopers, and raised the steppir to 75-76 feet up. My highest beam antenna I ever had of my own.
2. Hygain hytower with 80 meter 'stinger' removed and my 40 meter DX Engineering DXE-40VE-1 mounted as a ground plane on top of the tower. Gets out very well for DX, low angle of radiation but very noisey on receive. Four 34' radials on the ground plane. SWR is ideal and very broadbanded across the whole 40 meter band.
3. Four 40/80 meter quarter wave slopers off the tower at 72 feet or so. The slopers are NE,SE,SW and NW. I have to bring down the tower some time to dip in the 40 meter slopers. Right now the NE one dips in at 7.10-7.13 but the others are resonant down at the bottom of the band, 7.00Mhz. The 80 meter slopers are all dipped in between 3.7-3.780 Mhz so they are good for working DX and contest.
5. 135' of wire in an inverted L' arrangement for 160 meters. Goes up at about a 70 degree angle to 65' high, then bends over. Fed against the hytower radial system. Just rebuilt the tuning coil with solid 1/8" or 3/16" copper wire. 9 1/2 turns about 4" diameter with a jumper to bypass coils and tunes between 1830-1930Khz. Has about 60Khz of bandwidth, +-30Khz each side. It dip's in near 1:1 SWR.
6. K9AY antenna system for receive on 160 and 80 meters.
7. GP6 for 2 mtrs/440 on top of the mast reaching 85'. One of these days I need to dig out my 2 meter rig and hook that up.
Changed out the driven element EHU because of intermittent connection problems. Suspect the SO-239 'prongs' becoming loose. Also fixed a high SWR on 10 meters apparently caused by my not soldering the sheild onto the SO-259 connectors on the LMR-400 50 ohm coax. Added four 40 meter slopers and 2mtr/440mhz GP6 vertical again like in the big quad picture. The 40 meter 1/2 wave slopers had SWR issues running 1.5:1, 1.8:1 or higher. Having to lower down the tower to adjust the slopers was always a pain.
People are flexable, computers are ridged and inflexable. 30 hours of CQWW160MSSB contest and it takes about 6-8 more hours to get the log file uploaded to the server! ARRRGGGGHHHH! (2/22/2014, hooray, I submitted it first time this year!)

9/20/2013 Mail cost have skyrocketed. Sometime back I sent several large envelopes and a box of qsl cards to overseas bureaus. Even the 420 JA cards were less than $8-10. Now calculation of 1.7 ounces for the UK showed lowest price about $20! I just checked for 1.4 oz to Germany and it was unbelieveable. I have about 1 1/4" of cards to send to many bureaus but it just looks like I will throw them away because the price is just too high. Still I guess I will get around to sending them through the ARRL overseas bureau service while my subscription last.

51J-3 Collins RCVR with my dream 64' GTO and WWII jeep 1:18 scale models. I consider the 51J-3 a better receiver than the 51J-4 due to apparent AVC/AGC issues. Backing off the RF gain helps. Below is my 75A-4 I picked up recently and recapped the 'black beauty' caps in it. It works very well. It's in the back room right now because of lack of space in the ham shack (imagine that).
Above is an older picture of my messy shack (a messy shack is a happy shack). FT-1000mp, FT-1000D, etc. You might also note the 1965 El Camino picture on the monitor that's been up for several years. Below is Shaddow giving the eyeball (don't he look cool)and my Rohn 25 tower that is now the upper section of my Rohn 45/25 crank-up.
Having just one big tower I've always tried to add secondary antennas to get the most 'bang for the buck'. It always seemed like a waist to only have the beam or quad on the tower and little else. Only thing is it's always a problem raising and lowering the tower to adjust the SWR on the slopers or whatever secondary antenna I have. And I'm a guy if there is a nail, branch or anything to catch a wire within a couple hundred feet, I'll find it! Funny how that always works out that way.
That's the old man with Patrick 'fat cat' who weighs about 25 pounds and has claws (oh, did I do something wrong?). Poor Patrick is like Rodney Dangerfield, get's no respect around here. Even Shaddow and Hanna my wife's dog gang up on him. Pecking order I guess. Sometimes I take pity on him but then he drools too!
Below is my dream car come true.1965 El Camino. I added a couple more pictures of the El Camino. It's the time of the year when I keep it covered up and set a heater in it to make sure it does not get too cold. 'She's real fine my 350'.
Really looks good up there! And having a pulley setup with dacron line gives me the ability to raise and lower 40 meter inv V' or some other antennas easily. I run a long RG-8X feedline down from the remote switch box at the top of the tower to that antenna.
Winter time in Oregon, Febuary 7, 2014 saw 2-3 inches of snow (as of 21:28Zulu) today. And I was telling people how it looked like we would not get any snow this year! Wrong! The following morning I went out and measured 9" and still falling. Three days of snow in Oregon isn't usual!
Below is latest picture of the tower with the steppir at 75-76 feet (23.0 meters).
A couple of pictures showing my 'new' Elecraft K3 and Panadapter P3 that I put in place of my FT-1000mp. It was really stressful deciding to pull the Yaesu FT-1000mp out of line and put the K3/P3 in it's place. The Yaesu has given me nothing but solid, reliable service since 1996. But the K3 is suppose to have better capabilities for handling QRM and a generation or two newer receiver technology. I have been feeling the FT-1000mp has been having some problem dealing with the QRM in contest so I made the move. As you can see the Yaesu FT-1000D is still in it's place. The -1000D is still my favorite radio to operate just because of it's fine audio, 200 watts output and ease of use. For working split frequency I don't think it can be beat, definately better than the FT-1000mp. The K3 doesn't have the capability to listen on two frequencies at the same time. At least not without the second receiver according to what I have been told. The FT-1000D is realitively easy to adjust between the main receiver and the second receiver's audio levels. How may times have I heard former owners of 1000D's say 'I wish I had it back'.
Below is another picture of the steppir at 75 or 76 feet. That's the moon behind it. You can also get a shot of the 40/80 meter quarter wave slopers.
Hoping for great things out of the Elecraft K3 in coming up contests and DX chassing. I just have to learn how to use it better as far as the noise blanking and DSP noise reduction settings. I have not tried to adjust the audio pass band (equilizer) yet but am getting good reports with everything set flat with my Heil HM-10 (H-5 and H-4 cartriges). The switching between the 2.7Khz, 2.1Khz, 1.8Khz and 200 Hz filters is easy and straight forward. I just got a 6Khz filter to add for AM/General Coverage operation as well. Next thing will probably be the second receiver but learning to use the K3 it may prove not to be necessary when using the split option. So far the split operation is the only thing I did not like due to unlike using the RIT/XIT function that causes the transmit frequency to display when you hit PTT, split does not change the display frequency. You have to watch the B receiver frequency and the TX LED. Seems like it would be easy to transmit out of band thinking you were using XIT but being on split. I just wish the main display frequency would follow the TX to keep me of where I am.
I have just gone through the CQWWPH 160 meter contest and the K3 did very well. That ability to adjust the roofing filter from 6Khz, 2.7Khz, 2.1Khz, 1.8Khz all the way down to 200Hz is really sweet and cuts down the qrm. I noted one group who started a qso on top of me on the low side. I was able to move 1914.5 to 1915.0 and reduce the passband down to 2200Hz and remove the interfering signals. It really helps cut the qrm out.
Above is a picture of the old hytower 'tower' section with the DX Engineering DXE-40VE-1 40 meter ground plane. 4/07/14
Below is a picture from this last summer when I was working on the new crank up tower arrangement. Can you find my wife's dog Hanna in the picture?
This picture is from last year when I was rebuilding the tower and a new quad. The tower worked out but the quad was a failure and I put back up the steppir. There is alot to be said for a proven antenna with great SWR curves!
