ARRL 10GHz And Up Contest Results
Ron KO0Z just sent out a link to a very nice article about this year's ARRL 10GHz And Up contest (click here if you want to read it). That contest mentions many famous names and callsigns and even few of ours. It also mentions results. I am glad to publish here that Zack and Ron both made the "Top 5" lists in their call area!
Congrats!
Let's hope that we will have more contest participants and even better results next year. You can see the contest included in the BARS activities on the right side of this blog.

BARS December Brunch
Saturday, 16 December, the weather outside wasn't frightful and the company inside was decidedly delightful and none of us had thoughts of let it snow, let it snow, let it snow. Although the northern hemisphere's first day of astronomical, winter is only five days away, today felt like a fall day. Sunny skies, sixty-degree temperature and dry roads made it a perfect day for BARS December brunch and Christmas celebration.
In addition to 10 GHz beacons and 24 and 47 GHz transverters, a recurring BARS theme is wineries. Today we met at Chandler Hill Winery in southern St. Charles County (EM48) just a scant few miles from the historic Daniel Boone home. Herbert, AF4JF accidentally discovered the winery while out on a "Sunday" drive with his wife Alice in search of potential, suitable microwave locations. Great discovery H!
The winery opened at 11:00 am and Ron, KO0Z and Debbie arrived at 11:30 am to join Herbert, AF4JF; Mike, N0OBI; Harry, WA0CNS and Rich, N0PQU inside. The food was delicious and the company excellent. Inside we didn't cover many microwave topics. The winery provided live music and the band, although very good, made carrying a group conversation somewhat difficult.
Before too long, we went outside to the parking lot and Harry showed us his 24 GHz transverter and dish project. Herbert showed us his early Christmas present - a DB6NT 47 GHz transverter! Herbert wasn't even a bit hesitant and allowed us to touch it!
Mike, N0OBI, while at work, noticed a technician getting to discard a number of wall-wart power supplies. So Mike took them off his hands and gave them to Herbert. As luck would have it, I needed to replace my Peet Brother's Weather Station "Big Picture" power supply which was failing. I needed a 12 VDC, 1 amp supply and Mike had 12 VDC, 2.5 amp supplies which turned out to be perfect. Mike's wasn't sure if they all worked, but I am here to tell you that the two I selected work just fine and my home weather station display is once again working! Tnx Mike and Herbert!
Mike's wall-wart acquisition's proved to be just what I needed to power my weather display

Tid Bits
While watching PBS last night, 15 December 2017, there was a special over the scientific discoveries of Voyager I and II. The program mentioned that Earth's Deep Space Network is still able to detect Voyager II's radio signals even though it passed through our solar system's heliospheric bubble on August 2015 at one-trillionth of a watt! Now that is weak signal detection!
May I also commend to you the December 2017 article,"What Happens If China Makes First Contact?", by Ross Anderson in The Atlantic Monthly. The article explores the commissioning of China's new, Aperture Spherical Radio Telescope in Pington.
The article explores China's commitment to doing SETI research along with some existential arguments that are quite interesting.
This radio telescope is 500 meters in diameter! It will be interesting to see what new discoveries this world-class radio telescope will detect. The article also explores China's future plans to put a radio telescope on the dark side of the moon.

November BARS Breakfast
Today, Sunday 5 November, five BARS members met at the TA Truck Stop restaurant in Troy, IL for our monthly breakfast. Our December meeting will involve lunch at a winery in St. Charles County. Herbert, AF4JF, Harold, KD9SG, Bob, N0IS, Zack, W9SZ and Ron, KO0Z. Besides breakfast, today's gathering involved getting project ideas regarding 24 and 47 GHz. Zack brought both of his systems. Herbert is already on 24 GHz and well on his way towards 47 GHz. Ron is still working on putting his 24 GHz station. It was good seeing everyone this morning.

BARS September 30, 2017 Lunch
Litchfield, IL, I-55 exit 52, Maverick Steak House and Spirits restaurant, Saturday, September 30, 2017 at 10 am. Herbert, AF4JF, Zack, W9SZ and Ron, KO0Z met at the restaurant parking lot and moved a quarter-mile north to parking lot overlooking a field and Zack drove northward to a parking lot at the opposite end of the field, approximately 1 km to test out Herbert's 24 GHz transverter with a 432 MHz IF.
Zack and Herbert were able to hear each other quite well! A successful test for AF4JF! Ron, KO0Z is still working on his 24 GHz rig. He needs to get a 12 GHz doubler to proceed further.
It was a beautiful, fall Saturday with temps in the 70s and low humidity. A good day to microwave. After the test, we ate a big lunch at Maverick's and made plans for the upcoming microwave sprint/MAD on Saturday October 7th. Both Zack and Ron were able to copy the WB9PNU beacon in Bridgeton, MO with S-1 signals. Not very strong, but detectable. We had the I-55 off ramp ridge between us about a half-mile away which could have been blocking signals.

2017 ARRL 10 GHz and Up Contest, Round 2 or Trees, More Trees and Corn...
Saturday, September 16, the first day of the ARRL 10 GHz and up Contest 2017 Round 2 was spent by Herbert, AF4JF and I attending the TAPR DCC in Earth City. It was a day well spent and very informative. AF4JF and I made final plans for Sunday's contest outing.
Our major goal was to try out new microwave locations in EM49 and EM59. Google Earth is a wonderful tool for checking potential sites, but it's not until actually going there to check for foliage, ground depressions, tall weeds, etc., does the true nature of a potential site truly reveal itself. We've found that Google Earth is a good place from which to start.
Herbert, AF4JF remembered some good, potential spots along Powerline Road near Pere Marguette State Park, IL that were worth checking in EM49sa. I found a new hill in EM59fh with soy beans on it. The farmer gave me permission to operate from there. I also have permission to operate from the hill just to its east, so I should have a hill available to me depending on crop rotation.
Hill EM59fh southeast of Raymond, IL. The hill with the trees is also available.
Closer view of the EM59fh hill with soybeans this year.
My Cobalt made it up this road, it's much steeper than what the picture reveals.
Set up on top of EM59fh hillside looking towards Herbert, AF4JF southwest in EM49sa.
I was up and running by 9 AM. I could hear the WB9PNU beacon, but QSB made copy too difficult. AF4JF and I tried to make a 2 way QSO at 10:43 am, but tall trees with plenty of RF absorbing leaves at Herbert's EM49sa location ( 53 miles) stymied our efforts. Earlier I tried working Ron, W9ZIH in EM51nv, about 181 miles away, but we couldn't hear each other. Unfortunately, Ron has a tall hill towards my direction in EM59fh which makes copy difficult for Ron, W9ZIH
AF4JF photo: Notice Herbert's rig set up beneath the water tower. Over 800 foot elevation, but trees are in the way.
After trying both locations, our plans called for usto move closer to each other so I went to Gillespie about 28 miles away from EM59fh and Herbert moved to Jerseyville, IL EM49uc about 11 miles away from his previous spot.
I made it to Gillespie, but trees or corn blocked my view towards Herbert, AF4JF, 23 miles west of me. So what's a ham to do? Move west, young ham, move west. I drove down IL Hwy 16 to Shipman, where I found a good spot. A farmer had just harvested his corn field, which now gave me a good shot west.

Fortunately, this freight trail arrived after I made the QSO with AF4JF in EM49xc!
At 12:12 pm AF4JF and I made our first 10 GHz QSO of the day 21 km or 13.4 miles away.
Our plans now called for lunch, so I drove west to Jerseyville and we had a splendid lunch at Fran and Marilyn's restaurant on Main Street, also US Hwy 67.
The lunch selection is awesome and reasonably priced at Fran and Marilyn's
This picture and the one's below depict some of Jerseyville's beautiful architecture

This is another view from EM49uc looking east towards EM49xc. I was behind the direction of the tower in the center of the picture. The owner of the mowed property, at first, wasn't too pleased with me being there, but after explaining our purpose he was more amiable. .
After lunch, Herbert and I went back to the original EM49ua location and we decided to try to work Ron, W9ZIH in EN51nv. However, the northward view wasn't too good. Both Herbert and I looked for a clear spot to the north and about 100 yards east, we found a closed business with a view to the north. I set up and while trying to work Ron, the owner showed up in his pickup truck and after explaining what we were up to, he allowed us to stay since we weren't going to be there long. I was able to hear Ron with S5 signals, but he couldn't hear me at a distance of 206.6 miles (332.5 km). It was now 2:35 pm and Herbert needed to head back to St. Peters.
I decided to press on northward towards White Hall, IL to find a clear spot looking north towards Ron, W9ZIH.
A pretty, red barn somewhere along Hwy 67 between Jerseyville and Jacksonville, IL
At this point, I'm not even sure which town I am in when I took this picture. I believe it is Carrolton, IL
Along Hwy 67, all I found looking north were trees, more trees and cornfields. It was looking bleak. I thought about calling it a day. By this time I was about ten miles away from Jacksonville, IL and I remember seeing on a map a place called tower hill. I went to the west side of Jacksonville in Morgan County (about 30 miles west of Springfield, IL) and I saw a number of commercial towers.
I was now in EM49ur which is 43 miles north of Jerseyville. I finally found a site I could use!
Old, microwave tower, west of Jacksonville, IL EM49ur. Workable view to north finally!
Looking northeast towards Ron, W9ZIH in EN51nv 167 miles (268 km). Greg, KA9VDU in WI is dead center between the trees. Bruce, Janice and Glen, also in WI, are just left of the trees at the edge of the farm towards the left, down the road. Note the grain bin beyond the fence line. That is where I set up next.
I set up my dish near the microwave tower, but I had a lot of road noise on the highway. The picture above makes the heavily traveled road into Jacksonville look almost level with me, but I am actually about ten feet above the road. AT 4:45 pm, Greg, KA9VDU in EN53kt (288.2 miles, 463.8 km) tried to work me, but we had no luck whatsoever. Next, I called Ron, W9ZIH in EN51nv (167 miles, 268 km) and we finally worked each other. Ron had a terrible time finding my signal. I was drifting badly. Sometimes 5 to 7 KHz. I later discovered my coax connector from the 10 MHz OCXO is intermittent even though the transverter showed a locked signal.
After working Ron, W9ZIH, Bruce, W9FZ, his wife Janice, KA9VVQ and Glen, KC0IYT in EN42 px gave me phone call. I told them about my technical issue, but we all decided it was still worth a try since I'd be there most distant Q, 225 miles 362 km, if we made it. Darn well worth a try!
I wasn't too hopeful at this point; especially since their azimuth heading was just to the left of the tree in front of me. Well, what the heck, let's roll! I beaconed and they could hear my 10 GHz signal. They beaconed to me and I could hear them, but there was deep QSB. At one point, Bruce told me I was loud enough to copy CW, but then we had the problem of chasing my signal. Drats. Bruce commented, "If only we could one or two more dB!" It was sometime around 6:10 pm.
In the meantime, a nice homeowner just west of my location came by to check things out and he knew the farmer that owned the grain bin down the road and felt he wouldn't mind if I set up there as long as I wasn't in the way.
At this point, I decided to drive down the road about 300 yards with a clearer view towards EN42px, but I'd lose about 50 feet or more of elevation. Ten minutes later I was set-up and running, but with similar results. In fact the QSB was getting worse.
So close! We could hear each other! I can't help, but think that if my signal was frequency stable we may just of had the 2 way QSO! I'd like to thank Greg, Bruce, Janice and Glenn for trying!
I reset up about 50 feet lower from my prior EM49ur location about 300 yards behind me. I am looking towards EN42px.

By 6:35 pm, I was packed up and ready to go home to EM59ck...about a 45 minute drive. I was tired, but not exhausted. It was a good day of microwave experimentation and a very fun way to spend a Sunday with radio buddies.
