Progress on Bob (W7SX) Antenna Farm

Monday, August 3rd, 2020

Bob finished the tower/antenna installation today on his 6 meter antenna. It is an M2 5 element 6 meter Yagi, on which he modified the driven element into a folded dipole and then fed it with 450 ohm ladder line.

This tower/antenna is at one the peaks on his property and the base is anchored in a granite outcropping…all guy anchors are also in granite.

Picture 1: construction and mounting of the base plate…..extra heavy hinge is two telescoped pipes welded to the base and the tower base (standard Rohn backed with 1/4 inch steel plate.

Picture 2: Kubota delivering the top section from the shop 400 feet down

Picture 3: tower lowered

Picture 4 tower raised with the winch on the Kubota.

The tower is 30 feet but it is at the top of the property with steep drop-offs in most directions.

We encourage all our members to subscribe to the NCJ.

Congratulations to Bob (W7SX) for QST Cover & Article

Saturday, March 28th, 2020

In the March QST magazine, our own Bob (W7SX) has the feature article “Building Your Own Open-Wire Line” on pages 30-33. It is also featured on the magazine cover.

In the article, Bob shares the step-by-step construction of his incredibly efficient feed line. His rugged open-wire line holds up in difficult weather and works great even under high SWR conditions. This is the feed line he is using on his new antenna farm.

New SDXA Club Log Administrator

Friday, January 3rd, 2020

We all have enjoyed and recognized the features of Club Log as a valuable resource.

For several years the SDXA Club Log Administrator has been Chuck Williams (KI7DG). Chuck has done a fantastic job of helping SDXA members become active on Club Log and provided monthly reports on our progress for club meetings. Chuck is also the author of a great article on the SDXA Website at this
ClubLog 101 LINK that I would encourage everyone to read.

Chuck has felt now was time to pass the barton on the leadership of ClubLog. He will continue to serve as a second administrator, riding along as assistant to the new administrator.

Murf (N7UVH)

President Gary (AD7XG) has appointed Patrick Murphy “Murf” N7UVH as the new SDXA Club Log Administrator. Murf is a very active DXer and will do a great job leading the use of Club Log for the SDXA.

Another Member Tower Goes Up

New Projector For The SDXA!

Friday, January 3rd, 2020

UPDATE: In the November meeting the club voted to procure a new business quality projector for future presentations and conventions. I’m happy to report that we now have our new projector shown above. This is a commercial quality Panasonic PT-VZ580 projector with a resolution of 1920 x 1200 and a brightness of 5000 lumens. It also has two HDMI ports, 2 Computer RGB ports, Ethernet input, plus a few other audio inputs. Mel did a great job of finding a good buy that was under our budget we had allocated. To top it off, a anonymous donor added a waterproof Pelican 1610 case to keep it safe in transit. I don’t think we could have done better for our members and we hope you will enjoy the benefits of this new addtion for our club.

At this time, the specific link for the Projector donations are now closed. We managed to raise almost half of the total cost of the projector which really helped our treasury 🙂 So I want to extend a big THANK YOU to all of those who donated to make our club great and progressive.

Fall Tower and Antenna Work in the club

Saturday, November 9th, 2019

Mike Buettner (K7STO), with the assistance of Bob Lee (N7AU) and Woody Jacobson (N7HCJ) lowered Mikes 60 ft tower down. Performed yearly antenna and tower maintenance (checked every thing over) then added my first 160m antenna (inverted L) to the tower. Mike has a wonderful setup for raising and lowering his tower.

Jeff Banke (NZ2S) along with Greg Preuses (N6WCN) helped Gordon Olsson (AA6TQ) remove a dipole off Gordon’s roof and tighten some bolts on his yagi.

David Wilhelm (WA7TNT) is working on putting up his tower. David is completely rebuilding a Mosely TA-33 and hopes to install it at the top of 3-4 sections of Rohn 25. The hole is dug, rebar, tilt base plate bolts, and gin pole are in place. Base and first sections are in.

Bob Zavrel (W7SX) has been busy putting up wire antennas on his antenna farm. All are center fed wires with lengths of 50, 90, 110 and 220 feet and tree supported.

Mel Ming (N7GCO) just put up a Butternut HF2V vertical to give him another option on 40 and 80 meters. Put out 40 radials. Also added radials to his 160 meter inverted L antenna.

Jeff Banke (NZ2S) and Dave Lehman (WA7F) put up Dave’s 60ft tower. Jeff did the crane work and Dave the climbing.

Bob Hallock (K7TM) put up an 160 meter inverted L for Jim Monroe (N7ESU). They went up in the tree about 70-80 ft and then horizontal close to 100 ft.

Del Morissette (WA7AQH) received his SteppIR Urban Beam he won at the DX Convention. Hopes to get it up for winter.

I am sure there are others I have missed.
