ARRL 10 G & Up Contest, Leg 1, August 2026

 Leg one, August 15, 2026, of the ARRL 10 G & Up contest started with thunderstorms overnight early Saturday morning just past dawn. Today, it looked like it would only be Kevin AD7OI and myself and whoever else I could hear to operate leg one of the contest.  I decided to go for distance points. I, KO0Z left St. Peters EM48 amidst rain heading towards Litchfield, IL EM59ee at 7:00 am.  Plans are to be QRV by 9:00 am to work Kevin AD7OI located on one of our favorite microwave sites, Lover's Leap, high above Hannibal, MO EM49hq 100 miles away to my northwest.

                                               Rain just north of Litchfield early Saturday morning 

 Around 9:00 am Kevin and I tried to work one another but without any luck.  Kevin discovered an issue with rig. In the meantime,  I was able to hear the St. Louis 10 G beacon WB9PNU very well. Kevin's workshop is close by to EM49hq so while I waited for Kevin's return, I called CQ towards Chicago but with no response.  A very short while later, Kevin was back and both he and I tried again.  I could hear Kevin, but he could neither hear or see me on his Icom 705's display  We were 100 miles apart. Drats.  We attributed it to poor propagation.

I packed up and headed east 25 miles towards Ohlman Cemetery EM59ji.  It felt good to arrive at another one of my favorite microwave locations for it had been four years or more since I was there last.

           The sun was beginning to pop out between the rain clouds at Ohlman Cemetery EM59ji

 While at the cemetery, I could easily copy the WB9PNU beacon 73 miles to my southwest.  I then tried to work Kevin from this location, now 118 miles away.  I could hear him but once again, he couldn't hear me.  I suspected my transverter or its relay were malfunctioning.  Since propagation wasn't too good for either of us. Kevin kindly made available his excellent workbench in Hannibal to test my rig. Darn, so much for working distance points plans. Now I needed to drive a distance.  Ah, the best laid plans of mice and a frustrated microwaver...

 I'm glad I made the trek over to Kevin's.  We measured my output at approximately 80 milliwatts.  No where near my normal 3 watts output. I'll be sending my Xverter back to Steve at DEMI for his expert repair.  Oh well, I can now claim I'm working 3 cm QRPp!  Tnx Kevin for making you and your bench available to test my 3 cm rig.

Sunday, August  16,2026

Armed with the knowledge I am now operating 3 cm QRPp, my strategy changed.  I planned to operate closer in to our Sunday location - the Farmersville, IL gob EM59ek.I again left St. Peters EM48 at 7:00 am amidst light to moderate rain heading towards a rendezvous with Jim N9LQF, the keeper of the gate, at the Farmersville, IL  gob wind turbine just east of I-55 exit 72. We were up on  the gob by 8:30 am.

                              Driving up towards the wind turbine atop the Farmersville gob EM59ek.

 

                                         Me set up next to  the wind turbine on the gob.

 Soon Herbert AF4JF arrived on site and together we were set up ready to work our fellow microwave enthusiast and SLAMS member,  Jim KK0U who was setting up at Litchfield, IL to our south by 22 miles, which we both did.  We were also ready to work Kevin AD7OI and his wife Tammy KI7GV at Hannibal EM49hq.

     IDOT left their mowing tractors on top of the gob and Herbert used the trailer's additional height.

Herbert was able to put Kevin and Tammy into his log, but my 80 milliwatts wasn't punching through the 118 mile path.  I was able to work Jim KK0U 22 miles away with my QRPp station! After that QSO, I decided to rove around the gob to give Herbert and Jim more points.  I went to Morrisonville, IL, Pawnee, IL and finally at Virden, IL. I was able to put Herbert and Jim in my log.

                                                        Storm clouds over Pawnee, IL.

 It was now around 2:30 pm and thunderstorms were rapidly approaching.  Herbert tried to work Mike KM0Tvia rainscatter but with no luck on two different occasions.  So we packed up, left the gob and headed west to Girard to try out a new Mexican restaurant El Campineo.

 After a late lunch, Herbert left and Jim and I decided to take the "scenic" route back to Missouri stopping every 10 miles to find a location and then one of us would travel another KM to make a two-way QSO. It was a lot of fun and quite an adventure!  We ended up arriving home in EM48 somewhere around 7:00 pm.

On Saturday, I managed to add 350 miles on my new Subaru Outback.  Sunday, I added over 200 miles. 

ARRL 10GHz And Up Contest 2024

As Ron KO0Z mentioned in his posting last month, we were planning on publishing two narratives about our biggest microwave contest of the year. I apologize for being a little late with my addition, there is not much left to say what Ron did not cover in his posting anyway.

Let's start at the begin. First half of the contest, Saturday August 17 (2024). Ron KO0Z with Debbie KC9ULA went to Frenchman's Bluff while I was packing my station in the morning (I have returned from a business trip just the night before). Harry WA0CNS joined me with his 10GHz station for the day. Since we shared my car, we did not have space for higher bands this time. Ron went somewhere West along I-70 while Harry and myself tried to find the Frenchman's Bluff. Surprisingly, we succeeded and even found shorter way than last time. Nice, warm (well, hot) weather, blue skies and no rain clouds in the direction towards West where the location is open to.

Ron KO0Z arrived at Moberly airport in EM39sl while we were in EM49ma It's just 85 miles or so, but we did not hear each other - neither on mine or on Harry's station. Ron just worked NA0Y on 10GHz so we assumed that his station was working and decided to take a look at the terrain profile later at home ... and Yes, the terrain seems to be the problem. We were at the very bottom on the right hand side:

Moberly - Frenchamn's Bluff path

From here, we went to Hannibal to our favorite Lover's Leap in EM49hq to join Kevin AD7OI. Ron covered that part nicely in his narrative, so I will only add that I was not able to hear the WB0LJC group in Minnesota although Kevin worked them SSB .. well, not only his 60W station makes its own path through the atmosphere, but it also receives very good. Subject to look at during the coming winter (I intend to replace mu LNA with new one from Kuhne). I worked K9JK across reasonable distance that day.

Second half of the contest was more exciting. We only went out on Sunday September 22 (2024) and only to Louisiana in EM49lk. There were no rain clouds to use and generally nobody to work. Except Bruce W9FZ and Janice KA9VVQ who came close enough to us to make a QSO. It was hard, but we made 385km contacts! This was also the first outing where Jim KK0U joined us with 10GHz station.

KO0Z and KC9ULA's August 2024 ARRL 10 GHz and Up Contest Adventure

 Saturday, 17 August 2024, 9:00 am, Debbie KC9ULA and Ron KO0Z loaded up the pickup and headed to Frenchmen's Bluff at Cuivre River State Park in EM49ma which has a spectacular view to SW, W and NW.

                           Debbie KC9ULA and Toula with Ron KO0Z at EM49ma Frenchmen's Bluff
 

By 10:25 am Ron heard Greg WQ0P in EM19wf (Kansas) on CW with a 529 signal and QSB.  Greg could see KO0Z on his waterfall, but wasn't able to hear his signal.  Briefly, Greg heard Ron's signal for about 5 seconds.  Perhaps it was airplane scatter.  This was SLAMS first attempt at activating Frenchmen's bluff.   Both of them were unable to hear each other.  KO0Z also tried to work Pete NO0Y in EM18ct about 90 miles further west from Greg. On the up side, a young couple asked us if they could get in front of the dish which put them closer to the ledge.  From there, the young man proposed to the young lady and she accepted!

The weather was nice with temperatures in the upper 80s and partly cloudy skies.  No high pressure, heat dome for this leg of the contest.

From there, Ron and Debbie made their way just west of Kingdom City, EM38wf along the south service road of Interstate 70.

 After grabbing lunch at Arby's, Debbie and Ron arrived at Kingdom City EM38xw around 12:45pm.  Ron KO0Z EM38xw and Greg WQ0P EM19wf made a two-way CW QSO around 1:00 pm for a distance of 354 km (220 mile) 3 cm contact! Ron tried Pete NO0Y in EM18ct.  Still no luck.  Next Ron tried to put Gedas W8BYA, EN70, a 622 km attempt in the logbook.  No luck.  We even tried rain scatter with a T-storm over Louisville, KY.

At least EM38 provided us with a two-way contact.  From there we decided to head north via MO Route 63.  Herbert AF4JF and Harry WA0CNS were heading to Frenchmen's Bluff and planned to be QRV by 3:00 pm.  Debbie and Ron needed to find a suitable site.  They found it at Moberly airport, EM39sl.  It has a good view both east and west.

                                                         Moberly, MO airport EM39sl

Around 3:24 pm, Ron and Debbie attempted to put Herbert and Harry in their logbook.  It's only 136 km to Frenchmen's bluff, but neither party were able to hear or see one another.  Curious...  Darn the luck.  Oh well, time was beginning to run short.  We all had agreed to rendezvous at Lover's Leap EM49hq just south of Hannibal with Kevin AD7OI by 6 pm.  Consequently, Ron and Debbie packed up and left.  Regrettably, they didn't try to see if Greg was available.  They still needed to reach Macon and then take US Route 36 east to Hannibal.  About 90 minutes away.

Ron and Debbie made good time.  They arrived in Hannibal by 5:15.  They picked up a Casey's Taco Pizza and headed up to EM49hq.  By 6:00 pm they were set up.  Kevin and his wife Tammy KI7GVT Herbert and Harry were waiting for them.

 Kevin AD7OI was able to work John K9JK from EM49hq in Illinois on SSB.  Herbert AF4JF worked John K9JK from there on CW with his 5 watts but Harry wasn't able to hear John.  Ron KO0Z's rig blew a fuse and his spare so it was his turn to be "dead in the water." from this location.  Drats.  Kevin was able to work the Minnesota rover crew WB0LJC, WA9TT, N0UK & K0HC while they were in central Iowa, but neither AF4JF or WA0CNS heard their signals.

Propagation just wasn't as favorable this leg of the contest as it was the summer before.  This year a cold front passed through the area which provided much more conducive outdoor temperatures with lower humidity but poorer microwave propagation.

As Ron KO0Z was trying to figure out his rig failure, a bystander who is into astronomy wandered by and asked him what everyone was doing.  Before long, Ron discovered his name is Bernard and he is from France.  This gave Ron an opportunity to try out his very rusty French and they had a delightful conversation in French!

                                          Bernard from Paris inquiring about our contest activities.

All in all, not a bad day.  It was fun.  Ron and Debbie put on 300 miles and make several radio attempts, but managed only 1 contact for the day. Now to troubleshoot KO0Z's rig.  Would we do it again.  Yes, in a heartbeat!

ARRL 10GHz And Up Contest in September 2023 as seen by AF4JF - part 2

We have written several postings about this year ARRL 10GHz And Up contests non this blog site. I have published a video recording in my previous posting here (click to open) with a request for you to estimate how big a distance was covered by that nice FM QSO. I have received several email guesses, nobody posted a Comment here on the blog, so I am going to say it here. This video shows a 10GHz Rain Scatter QSO that spanned 299km between Greg WQ0P in EM19wf and Ron KO0Z in EM38pw. Once again:

This was not the first video that I have recorded that day (September 16, 2023). I have worked Harry WA0CNS from EM48qs while he was at his usual location in EM48rl. The distance is just 33km, but the signal usually is not strong enough for SSB for there are hills between us. We made it on SSB this time, but the next video recording shows just the lining up phase of the QSO (I did not have enough hands to operate my station and record it):

I have one more recording from that day (September 16, 2023). It demonstrates how strong our 10GHz beacon (WB9PNU/B) located in EM48ss was at my location in EM48qs that morning, about 15km away. We usually do not hear the beacon there at all, for there is a ridge between the locations:

Last recording is from the first leg of the SPRINT Microwave contest on Saturday May 6, 2023 in Hannibal. Location is Lovers Leap in EM49hq, the beacon in EM48ss is 129km away. As you can see on the recording, I am pointing to a tree and our beacon comes through Rain Scatter:

Let me finish this posting with a picture - one that shows how beautiful the place above Hannibal where we usually go in EM49hq really is. This is from August 19, 2023, first leg of the ARRL 10GHz And Up contest:

SPRINT Microwave Contest - May 6, 2023

Harry WA0CNS and Herbert AF4JF went to Hannibal, MO in EM49hq to participate on the SPRINT Microwave contest today. They met with a local HAM and SLAMS member Kevin AD7OI at Lovers Leap on the cliff above the Mississippi river in Hannibal. Weather was not so good at the begin, but turned to be better towards the end of the contest.

(approximately towards Fort Wayne, IN)

This location repeatedly proved itself to be good for 10GHz, especially with Rain Scatter or Trop propagation enhancement. Listen to the Saint Louis SLAMS beacon on 10GHz:

We have brought 902-1296-2304MHz equipment and especially 10GHz. Some pictures with the 10GHz stations:

Weather forced us to hide in our cars for a while today. We like thunderstorms during our outdoor activities, but not necessarily right above us. Following picture shows Herbert's rack with lower band transverters inside the car in the middle of moving the equipment to safety:

to plastic boxes or to the back of his car

Despite the weather challenges, we have had a good time and lots of fun trying to work (and working) all the stations available. We certainly will return to this location in the future!

August 2022 ARRL 10 GHz and Up

 Saturday, 20 August, 5:00am, my alarm woke both me Ron KO0Z, and Debbie KC9ULA up.  After quickly showering, Debbie, Toula (our Aussie) and I met up with Herbert AF4JF and Harry WA0CNS in St. Peters by 6:00 am and formed a caravan up to Hannibal, MO EM49hq for the first leg of the ARRL August 2022 10 GHz and Up contest.  We were looking forward to meeting two, new SLAMS members Kevin AD7OI and his wife Tammy KI7GVT who recently moved from Arizona.  Kevin and Tammy are originally from Hannibal and both are experienced microwavers. 

 AD7OI has a very strong signal with his 10 GHz 60 watt signal!  We all met up just south of Hannibal at Lovers' Leap EM49hq.  This river ridge park is an excellent microwave location.  

Pictured left to right:  Debbie KC9ULA, Harry WA0CNS, Herbert AF4JF, Tammy KI7GVT and Kevin AD7OI at Lovers' Leap EM49hq, just south of Hannibal, MO.

 After our meet and greet, we set-up our rigs and began to make contacts.  One attempt was with some buddies near Cedar Rapids, but band conditions were not with us even with Kevin's 60 watt flame thrower.  However our group had much better luck working Gedas W8BYA, 337 miles (537 km) away near Ft. Wayne, IN!  We also succeeded working Zack W9SZ north of Champaign, IL in EN50rl 159 miles (256 km) to our east.  Zack went to another hill in EN50 for a successful 10 GHz Q.  

Ron KO0Z and Debbie KC9ULA crossed over the mighty Mississippi River to John Hays Recreation Area in EM49hr72. It is clearly visible a mile away as a gravel area from Lovers' Leap.

      The yellow arrow points to the Hays Recreational Area in East Hannibal about 1 mile away.
 

 Unfortunately Ron, Herbert and Harry were not able to make a successful two-way 24 GHz Q.  Herbert and Harry could hear me, but I was only able to copy one of them just for a short time, but not long enough to make a valid Q.  Drats.  But the weather was nice and the breeze across the river was welcome.

              Larry KA9GWM spotted our uW activity and stopped by for a nice "eyeball" QSO.

 

 

Once we completed our EM49hq Qs, our next stop further down MO Hwy 79 is Lousiana, MO.  Zack W9SZ was making tracks for Ohlman Cemetery EM59ji and we needed a clear shot.  This was our first attempt to work Ohlman from this location.  We arrived on site after 2:00 pm and set-up. Although, we had partly cloudy skies, rain clouds were forming to our east which gave us rain scatter opportunities.

We worked Gedas W8BYA (322 miles, 518 km) and Zack W9SZ  ( 98 miles, 157 km) from that location.  Lousiana is another good uW location towards the northeast through southeast along the Mississippi River.

              Kevin AD7OI's dish aimed  towards Zack W9SZ in EM59ji from Louisana EM49lk.

 

 Kevin, Harry and Herbert made two-way 10 GHz Qs with Zack from Louisana to Ohoman cemetery!

Our next Saturday stop would be the park and Cottleville, MO  EM48qs and Dow, IL EM49ua.  Zack left Ohlman and headed towards Dow.  In the meantime, we parted company with Kevin.  He headed back home to Hannibal.  It was great meeting him and Tammy for the first time.  We made plans to continue with the contest on Sunday.

   Tired, but not exhausted 12 hours later Harry WA0CNS and Herbert AF4JF made a successful 10 GHz two-way Q with Zack 25 miles away at Dow, IL.  EM48qs to EM49ua.

 Twelve hours later Harry and Herbert made a ten gig contact with Zack W9SZ in Dow.  As luck would have it with microwaving, the shortest distance contact proved to be the most challenging.  It took a few tries, but the effort was worth it!  A huge rainbow complimented everyone's efforts.  Fortunately for us we had a few miles to go before home.  Poor Zack had at least a 3 hour drive for him back to Champaign, IL.  

Sunday, 21 August 2021  

 On Saturday we all agreed to not get up so early on Sunday.  Herbert called me around 9:40 am and asked if I'd like to accompany him to Kingdom City EM38xw to work Kevin planning to set up somewhere Macon, MO.  Sure!  A tall coffee cup later from Flying J Truck Stop and armed with a banana and two apples I was ready!  We arrived at our location along I-70 about 3 miles west of Kingdom City EM38xw to work Kevin AD7OI.

Successful 10 GHz Q with Kevin AD7OI Sunday afternoon from EM39xw and EM39uf.  About 25 miles.

 

Herbert AF4JF tried to work Harry WA0CNS in EM48pq, near High Ridge, MO but no luck on this attempt.

 EM38xw, about 3 miles west of Kingdom City alongside the I-70 south service road.  It's a good spot in almost all directions.  Noisy with all the interstate traffic, but not a bad contest location.  AD7OI and KI7GVT joined us for another meet and greet and to check out this location for future reference.  Afterwards we headed east towards St. Peters and Kevin and Tammy went into town for lunch.

All in all, a great contest and 10 GHz outing.  As luck would prevail, we got our 24 GHz rigs working towards the end of the contest.  Next month!
