ARRL 10 GHz & Up Contest, Leg 2, September 2026

Typically, the middle of September in Missouri can either be hot or cooler.  The weekend of September 19-20 was hot, grueling hot and humid. Humidity percentage in the 70s and temperature in the mid to upper nineties.  Armed with copious amounts of ice and water, Herbert AF4JF and Ron KOØZ left the comforts of home in EM48qs (St. Peters) northwards towards one of our all time favorite uW spots, Lover's Leap, EM49hq overlooking the river town of Hannibal at O dark thirty...5:00 am. We encountered several deer along MO Hwy 61 on the road's shoulder. Fortunately, no mishaps. 

                                                              Getting up at O-dark-thirty

We needed to leave so early, to make the 120 minute drive to Hannibal and to be set-up and ready to work Gary WBØLJC in central Iowa working his way back to Minnesota. We arrived on site, quickly set up and greeted the morning's sunrise.

 At 12:21Z both of us worked Kevin in EM49hp only a few km away from EM49hq. At 13:13 Z, we put Gary WBØLJC in our log book from Iowa, EM 32fg, a distance of 340km!  

                                               Pointing towards Iowa and Gary WBØLJC.
 

Next we worked Gary in EN32GKJ for another 340km path about an hour later.  We listened for Greg WQØP in Kansas.  We heard him dashing but he wasn't able to log us.  Drats!  Our path to the west is not that good from Lover's Leap.  However, we did log Gary again at 16:12Z in EN32kj.

KOØZ decided to add a new dynamic to our trip by heading north toward Palmyra, MO EM49fv.  The hardest part about roving is trying to minimize travel time and to find a suitable site to operate.  I found a construction company with a gravel road to a farm field which proved suitable to work Herbert, Kevin and Tammy.

 Where to next?  Tnx to Kevin, he suggested Villa Katherine in Quincy, IL EM49hu.  This architecturally  interesting building from the early 1900s has a commanding view of the Mississippi River. From there I worked Herbert, Kevin and Tammy. I found the Qs to be invigorating, but I was also looking forward to my car's air-conditioning.  I drove back to Lover's Leap, and Herbert and I made the short jaunt to see Kevin's shack.  His QTH is even higher in elevation than Lover's Leap.  Add to that a 75 foot tower with his 40 watt 10 GHz rig with dish on top of the tower and we have a new Midwestern "anchor station" that Kevin plans to also offer a omni, 10 GHz beacon!

 After visiting with AD7OI and KI7GVT, we made our way back to St. Peters.

Sunday, the 20th found Jim KKØU, myself and Debbie KC9ULA heading towards Pere Marquette State Park near Godfrey, IL EM48rx. Thankfully, we didn't need to get there until 10:30 am.  Jim was up and ready by 10:15 am at EM48qt (MidRivers Mall in St. Peters, MO).  Around 1540Z we easily made a two-way Q with Jim.  I could easily copy the WB9PNU beacon 1Ø368.9ØØ telemetry 4 watts out, 12.5 VDC, 98 degrees outside and 102 degrees inside the box.

Next we worked Jim atr EM48OT then EM48mw, EM48kx and EM49ia near Hawks Point, MO, our most distant Sunday Q.  Jim discovered bouncing his signal off of city water towers works really well!

After working Jim, Debbie and I went to Dow, IL EM49ua, an old AT&T microwave site to work Kevin and Tammy back at EM49hp on phone.

Now it was time to pack it in and to head back home but not before working Kevin and Tammy from MidRivers Mall in EM48qt.  To save time, we took the Grafton, IL Ferry across the mighty Mississippi to St. Charles county.

 

I dropped off Debbie back home and I went to the mall parking lot.  Around 23:00 Z I was able to hear Kevin, but we didn't have a two-way path.  But wait, I saw a thunderstorm to my northeast centered over Ramsey, Il (approximately 80 miles away) and Kevin, Tammy and I were able to make another QSO!

 All-in-all, a rewarding, exhausting, exhilarating contest.  Propagation wasn't the best, but hey it was good to once again have my rig at full operating power of 3+ watts!  Thanks Kevin for the use of his workshop,  to Steve at DEMI for looking at my transverter, Herbert for giving me a new relay and to everyone who was on the air over these two contest weekends!

 

Oh before I forget, a personal joke among SLAMS (St. Louis Area Microwave Society) members is we should plan our activity around a winery.  Well, we finally did it.  Just south of Hannibal on MO Hwy 79 is a winery at Mark Twain Cave.  We finally did it!

10 GHz Tower Scatter from Hannibal, MO!

 10 GHz Microwave Scatter from Hannibal EM49 or Mark Twain ain't got nothing on us!

 

Kudos to Kevin AD7OI who posted this video of his rig listening to the St. Louis WB9PNU 10 G beacon in EM48 from atop of DePaul Hospital scattering off a local Hannibal EM49  water tower!

Tnx Kevin for the video!

 

 

 

 

 

WB9PNU/B January RS

 Not much in the way of local microwave activity this winter.  Yesterday, January 25 the St. Louis metro area had a rainy day.  I decided to drag my 3cm rig next to my back porch doorway to see if I could hear the WB9PNU 3 cm beacon.  I am happy to report that it is working nicely!

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:

Lovers Leap, EM49hq

WB9PNU/b and Rainscatter

 I'm glad the WB9PNU/b is back up and running on 10.368.900.  Today, Tuesday, Septermber 8 around 2 pm, I noticed there were thunderstorms north of my St. Peters, MO EM48qs QTH.  This afforded me the perfect opportunity to take a break from remote learning with my grandkids and to see if I could hear the beacon via rainscatter.  I was able to copy it rather well.  Although the beacon is only 10 miles away (16.7 km) from my QTH, I don't have a line of sight path.

WB9PNU/b from EM59ji

Panaroma of Ohlman Cemetery Hill, EM59ji

Sunday 18 August.  Once again I woke up early to make the 45 mile trek to Ohlman Hill Cemetery in EM59ji.  This is a great microwave location.  I will attempt to post some videos of my visit there over the weekend.  Today the WB9PNU/b was again roaring in to my hilltop location.  Unfortunately, I wasn't able to work Jim, N5MU at EM48sq today nor was he able to hear me.  I tried working Ron, W9ZIH, but we weren't able to hear each other.  It started to look a bit glum.  However at 14:00Z I was able to make a two-way with Bob, WA5YWC in EN52sa (192 miles)!  Debbie, KC9ULA and I again tried to work Jim, N5MU who moved to a different end of theEM48sq location .  Again no luck.  By this time the WB9PNU/b was able to be heard, but it was only a S-0.  Debbie and I went to lunch while Bob moved to EN51xr.  When Debbie and I returned to the cemetery we worked Bob at 18:00Z a distance of 175 miles.  I was also still able to copy the WB9PNU/b at S-0!  Wow what a great microwave day!  Tnx to Bob and his buddy for driving all the way from Dallas, TX to be a part of this contest!  In fact a big tnx to everyone who participated!

73,

Me working Bob, WA5YWC from EM59ji to EN52 sa a distance of 192 miles!
