Better late than ...

 Better late than never, isn't that how the saying goes?  On Sunday, September 3rd, SLAMS members gathered at Dennys in Maryland Hgts for breakfast.  Afterwards, many of us went to upper Creve Coeur park to test out some of our microwave gear ahead of the September leg of the ARRL 10 GHz and Up contest.

ARRL 10GHz And Up Contest in September 2023 as seen by AF4JF - part 1

 I will publish two postings in addition to Ron KO0Z's article here (click).


  • This one that shows a video recording without details
  • Next one with some video recordings and pictures from my point of view

So here is a video. It records part of a QSO using FM modulation. Listen to it and let us know in comments below this posting what band do you think this was recorded on (that is easy) and, more important, what distance do you think this was held across:



2023 September Leg of the ARRL 10 GHz & Up Contest

What a difference a month can make!  A month ago, in August, we were broiling.  A huge, omega block created a high pressure ridge combined with very high humidity, it made for oppressive heat, but outstanding propagation.  A month later in September, we experienced cool mornings and afternoons in the low eighties.  Nice!

For the second leg of the ARRL 10 GHz and Up contest, SLAMS members decided to head west along I-70 from St. Louis and U.S. 36 from Hannibal.  Harry WA0CNS anchored the east end of I 70 at High Ridge, MO EM48rl. Ron KO0Z and Herbert AF4JF headed west along I-70 starting in St. Peters, EM48qt and EM48qs.  Kevin AD7OI and his wife Tammy KI7GVT handled the U.S. 36 corridor.

While we were planning our strategy, we jokingly called this leg of the contest our Iron Skillet assault.  Herbert AF4JF and truth be told, Ron KO0Z love eating at Iron Skillet.  There is an Iron Skillet located in Kingdom City and one near Odessa.  Lunch and dinner were covered on Ron and Herbert's end.

Both teams began early Saturday morning 16 Sept.  The contest started off poorly for Ron. Only three miles apart, Ron wasn't able to hear each Herbert.  Ron was at MidRivers Mall and Herbert was at the community college park. Ron met up with Herbert at his location.   Ron's receiver was deaf. Perhaps it was the relay, but after loosening and tightening some SMA connectors that appeared to correct the problem. KO0Z worked Harry WA0CNS in EM48rl, a distance of 20 miles/32km.  Earlier, Herbert worked Harry and Gedas W8BYA in EN70jt (321 miles/517km)!

 Next stop was Foristell, MO EM4mt.  Ron and Herbert logged Kevin AD7OI and Tammy KI7GVT near Macon, MO EM39sv (110 miles/177km) on SSB around 9:55 am.

                                   Foristell EM48mt proved to be a good location

 

      An hour later and further west along I-70, Ron & Herbert located near New Florence EM48gv.  Google Earth didn't indicate MO DOT was installing roundabouts off the I-70 off ramp.  The north service road was closed going east towards our initial uW site near the Ameren MO solar panel array farm.  Worse yet, one of our favorite wineries was on the same, closed road!  Drats.

However, hams are resourceful and we crossed over to the south service road and found a suitable location almost directly across the solar panel farm at a nursery.  Fortunately for us, the nursery was closed and we set up in their driveway.  Whereupon, we logged Kevin AD7OI and Tammy KI7GVT in EM39sv (87 miles/140km) on SSB around 11:18 am.  We tried to work Wyatt AC0RA in EN32xb (472 miles/760km) away near Cedar Rapids, IA.  We heard him faintly and he us,but not well enough for a two-way QSO.

                      Ron KO0Z in EM48gv.  Note the Ameren solar panels along I-70.  We logged Kevin and Tammy in EM39sv 87 miles away on SSB.

 

Now it was time for lunch and that meant traveling 30 miles west to Kingdom City, MO and Iron Skillet.  We were in for a rude awakening.  Herbert enjoys their soup and Ron their salad bar.  The buffet is gone!  What a major disappointment. We blamed Murphy for the early morning difficulty with KO0Z's rig and for the missing buffet.

     
   
 
 Looks can be deceiving.  Although AF4JF is smiling for the camera, he is disappointed the buffet is gone from Iron Skillet.  FYI, so was Ron.  He was so looking forward to the salad bar.

After lunch, Ron and Herbert went to nearby EM38xw.  We've been to this location before.  It is just west of the EM38/EM48 grid border.  Around 2:10 pm we worked AD7OI & KI7GVT now located in EM39ur (56 miles/90km) on SSB.  We also logged Wyatt AC0RA and KC0SKM in Iowa EN32xb (216.5 miles/348km) away on SSB!  Both of us were also able to log Greg WQ0P in Kansas EM19wf (220 miles/354km) on CW via rainscatter!

            KO0Z's rig aimed north towards AD7OI, KI7GVT in EM39ur (east of Macon, MO) and AC0RA, KC0SKM in EN32xb.

Tired but undaunted, Herbert and Ron's next I-70 stop was a regional airport near Boonville, MO, EM38pw.  Around 3:58 pm we logged Greg WQ0P in EM19wf (185miles/298km) via rainscatter and FM! We tried working Mike KM0T in EM13vb but no propagation paths existed between us at the time.

Looking in WQ0P's direction from Boonville airport (EM38 pw).  We logged Greg on FM via rainscatter.  Note the gathering storm clouds associated with an advancing cold front.


More tired and still undaunted, AF4JF and KO0Z head off westerly to our next location Nelson, MO, but somehow we missed the turnoff and went a few more miles down I-70 to Marshall Junction.  We ended up near a water tower and the rain was coming down.  Looking at the weather radar we could see a "train" of T-storms along I-70 from Kansas to our location.  When you're in the middle of a T-storm, rain scatter isn't viable.  By this time is was close to 6:00 pm, the storms were not letting up, so we decided to call it a day and to head home.  We ate dinner near Booneville since Iron Skillet did not have its buffet.  All in all it was a very good day!

On Sunday, Herbert and Ron gathered at the MidRivers Mall parking lot in an attempt to put Mike KM0T into the log.  Mike needs EM48 for a new grid but there was no propagation between us.  Only sunshine.  Debbie KC9ULA came along today and we ended up working each other on 10 GHz and 24 GHz before calling it a day.

Here is AF4JF's APRS map of our Saturday "Iron Skillet Assault."
 
 

              We made it two-thirds of the way across the Show-Me-State for this leg of the contest.

Sept ARRL VHF Contest 2023

 Saturday, 9 September 2023.

The 2023 ARRL VHF Contest began at 1:00 pm today.  Harry WA0CNS, Herbert AF4JF and Ron KO0Z met at Winfield Lock and Dam #25 EM49pa to start the contest.  From there we went to a nearby hill in EM49oa to work Marshall WD9EXD in EM57 on 1.2 GHz.  Only Herbert was able to make a two-way contact with him.

                                 Looking southeast from EM49oa.  Not too good for 10 GHz.

From there we went back to Winfield Lock and Dam #25 on the Mississippi River where we worked each other on 144, 222, 432, 1.2 G, and 10 G.  Harry and Herbert completed Qs on other bands such as 2.4, 3.4 etc. By this time it was getting late in the afternoon and we called it a day.

 While Ron KO0Z/R was waiting for AF4JF and WA0CNS to work each other on the other uW bands, he noticed that there was a nearby geocache located at the entrance to the Lock and Dam.  On his way out, he stopped by the site and found the geocache!  Herbert AF4JF had already found it on prior expeditions.



                                       The geocache was easy to find near EM49pa.


             While at EM49pa, Ron KO0Z/R tried to hear the WB9PNU beacon in St. Louis.  No luck.  Herbert AF4JF had tried with no success on prior trips.  However, this time his Icom 705's panadapter saw the beacon's signal.  He peaked up on it, adjusted his elevation and we could hear it.  Ron did the same with his Yaesu FT 817 and could hear the beacon.  Here is a little audio clip of the beacon along with horns from cars in the parking lot.

MAD Sept 2, 2023

 MAD, 2 September 2023

SLAMS members Ron KO0Z and Herbert AF4JF operated Saturday morning.  Herbert went to the Winghaven location to try and work Pete N0OY in Kansas.  No luck with that contact.  Ron went to EM58bv near Hamel, IL to see if he could confirm that grid square for Gedas W8BYA.  Once again, no luck with direct signals.  However, Ron did hear the WB9PNU beacon and he worked Herbert AF4JF who moved his location to St.Charles Community College EM48qs.  They worked each other using CW.
