MAY MAD DAY 2026

 Saturday, May 2nd, 2026.  A partly sunny day with temperature in the mid 50s.  Herbert AF4JF, Harry WA0CNS and Ron KO0Z arrived at Hwy 370 Lake Park only to find our preferred parking location for testing microwave gear overtaken by a Farmers Market.  I've never seen the park so crowded.

 We managed to find a few spots near the RV camping area to test our gear.  Our primary purpose was to work out the transmit receive split in Harry's PLUTO. And to make some uW contacts for the CSVHF sprint.  A few hours of experimenting did not produce any tangible results.  Herbert discovered his FT 817's RIT was damaged after a fall a few years back.

Ron brought his 3.4 GHz rig, but he needed another PTT cable to key the transverter.  Darn. 

 In the meantime, Ron went to Iffrig Road, near the levy to make a 3 cm contact for the CSVHFS uW sprint today.  Unfortunately the cable to my PTT RCA came loose, requiring a home repair.  No QSO for Ron.

On the bright side, Herbert worked Harry on 3 cm and Ron was able to copy the WB9PNU/b at Iffrig Road.  It was a bit noisy with some QSB.

The telemetry indicates an output power of 4.8 watts (inaccurately high...it should be around 3 watts), 12.3 V, 64.7 F and 70.6 F.

Annual SLAMS November Get Together 2025

 Saturday, November 16, 2025 couldn't have been nicer in terms of weather, setting, food, friends and conversation.  The temperature was close to 80 F, unseasonably warm, but welcome nonetheless.  A great day to join friends at Chandler Hill Winery, near Defiance, MO in St. Charles county EM48.

Great lunchtime cuisine, a wonderful waitress and fun times awaited Kevin AD7OI, his wife Tammy KI7GVT, Harry WA0CNS, Herbert AF4JF, Debbie KC9ULA and her husband Ron KO0Z.  Kevin and Tammy made the drive down from Hannibal EM49 and it was visiting with everyone.

Looking forward to next year!

 

2nd Weekend ARRL 10 GHz and Up Contest 2025

                      September 20& 21, 2025 ARRL 10 GHz and Up Contest

 Although, the 10 GHz and Up contest isn't quite over as I compose this blog, the writing muse is here and my 8 month old granddaughter is napping, so, I'm taking advantage of the time. This year SLAMS has had a few setbacks due to some medical issues, time commitments and equipment difficulties. But it's hard to keep a few good hams down for long.

 Herbert AF4JF, Harry WA0CNS and Jim KK0U may want to share their experiences in the contest. As for me, KO0Z, I only participated in the contest on Saturday for about one hour.  My stepson's wife had a medical emergency which required me to put on my "grandpa hat" to watch my granddaughter, but I was able to test out my 10 GHz rig. Previously, before the contest I installed a new dish, feedhorn arm extender and mini hardline to the external relay.

On Saturday, 9-20 I set up at MidRivers Mall west parking lot (EM48qt) to listen for Herbert AF4JF and Harry WA0CNS transmissions from Pere Marquette State Park in IL (EM48rx).  Jim KK0U joined me at MidRivers.

While waiting for Herbert and Harry to set-up, I copied the WB9PNU beacon via rainscatter from DePaul Hospital's roof which is about 12 miles away.  The beacon sounds good. I copied the beacon telemetry at 10:03 CDT:  4 watts out, voltage 12.3 DC, enclosure temp of 98 F and PA temp of 100 F.  Around 11:00 am, we were ready.  I transmitted to Herbert but he couldn't hear me.  Jim was able to hear me, but he was only 10 ft away. Herbert's signal was 599 +.  We were only less than 13 miles apart.  Herbert and Harry were able to copy Jim with strong signals. 

Obviously, I have some work to do.  I suspect my external relay may be the culprit. Drats! At least the receive side of my rig works!  I wish I would have been able to accompany Jim from there.  Our original plan was to travel along I-70 every ten miles or so to work EM48rx.  However, unexpected grandpa duty required me to get back home pronto.  I must admit, having a rig with little output made quitting the contest early easier to swallow. 

Now, I need check out that external relay.  Hopefully, that is my transmit issue.

ARRL VHF September Contest SLAMS Radioactivity

 Sunday, September 15 wasn't too hot or too humid.  Herbert AF4JF was busy on Saturday, so was Ron KO0Z and Harry WA0CNS. Consequently, the first half of the ARRL VHF contest was missed, but on Sunday we got together to at least participate a little bit in the contest.

We didn't intend to be competitive, instead, we just wanted to test our gear and to make a little RF noise on the bands which we accomplished.

I wasn't all that well prepared.  I tried out my new 2.3 GHz transverter and I didn't get it on the air.  My 3.4 and 10 GHz rigs worked fine.  Herbert and Harry also had other bands with them.  

All in all, we didn't even come close to breaking any personal records, but we did manage to carve out some time to get outdoors and to make a few Qs!

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.

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.

SPRINT Contests 222 and 432 MHz - Spring 2023

Herbert AF4JF, Harry WA0CNS and Ron KO0Z participated in the CSVHF SPRINT Contests for Spring 2023. There was a posting describing the 144 MHz SPRINT on April 10. The 222 MHz SPRINT took place on April 18 and the 432 MHz on April 26. This posting brings pictures from the 222 and 432 MHz contests.

In general, the lack of VHF+ activity in our area affects these short contests too. Not sure why - the SPRINT contests are well known and submitting the results is easy. We need to keep convincing local hams to use their radios (even FM handhelds) to participate!

Herbert tested his new set of rover antennas during this Spring set of SPRINT contests (more to come during the microwave section). Ron switched between his dual-band loops and hand held Yagi for 432MHz today (sorry, no picture taken). Harry changed antennas too and actually worked us with the shorter beam with folded dipole.

We will all participate in the Microwave SPRINT on Saturday May 6th. Looking forward to it!

KO0Z's Limited Participation in the Aug 2022 ARRL UHF Contest

 Usually I haven't been available to work the ARRL UHF contest in August.  The West Central Illinois Hamfest near Carlinville, IL used to occupy the first Saturday in August.  This year the hamfest was moved to the second Saturday in August.This year I can participate, but I'm still in the process of setting up my shack, and I am inching ever closer to getting back into contest mode.  I did make it by to see Herbert AF4JF at the nearby community college and we made plans to operate from EM38 on Sunday, August 7th.

Herbert woke up earlier on Sunday to attempt working tropo on 10 GHz. Not being as ambitious as Herbert, I sacked in a little later.  I only brought 24 GHz, 25 microwatts of power that Harry WA0CNS kindly lent me.  I left my St. Peters QTH around 7:50 am and I was on site, EM38 shortly after 9:00 am.  I parked nearby Herbert and set up, just to check our equipment.  My microphone wasn't keying up the rig for some reason.  Herbert's microphone worked, but he needed it to work Harry WA0CNS in High Ridge.

We decided I would send CW and Herbert would reply with USB.  I drove west along the service road about 8 tenths of a mile and found a nice, gravel, pull out to set up, well out of traffic's way.  It took some time to aim the dishes and to optimize.  Herbert's USB signal was very distorted, but I was able to copy.  AF4JF's location is EM38xw28 and mine was EM38xw18.  We made the two-way 24 GHz Q at 10:13 am CDT.  Our 15 mile, 24 GHz Q in July proved to be much easier!  Go figure!

All in all, it was a fun trip and I thank Herbert and Harry for the opportunity to participate.

2021 August ARRL 10 GHz and Up Contest

 Saturday, 21 August.  Hot, humid, hot and humid.  Nonetheless and somewhat daunted, Herbert AF4JF, Harry WA0CNS and Ron KO0Z participated in the ARRL 2021 10 GHz and up contest.  Ron went along for morale.  His DEMI transverter is QRT from his last rain scatter excursion.  He met up with Herbert at EM48qt (St. Charles County Community College) park to work Harry near High Ridge, MO.  AF4JF has the details in his account on this blog site.  Around noon, we decided to call it a day and get ready for our big outing to Louisiana, MO EM49lk on Sunday.

Sunday, 22 August turned out to be a cooler and less humid day.  Harry, Herbert and Ron met at the local QT (EM48qt, tee-hee) to make the trek up Hwy 61 to Hannibal.  Along the way, some wayward deer almost became hood ornaments on Herbert's Chevy Traverse.  Fortunately, no mishaps to report.  We were set up and QRV at Lover's Leap, just south of Hannibal, EM49hq.  Herbert worked W0ZQ and WB0LJC in EN42bm.  Herbert and Harry made a 5 km 2 way QSO on 122 GHz but 24 GHz eluded them. 

From Hannibal, our next stop also overlooking the Mississippi River was Louisiana, MO EM49lk.  We worked Zack  W9SZ and John K9JK in EM59ji from there on 10 GHz.  From there Zack and John went to Dow, IL EM49ua.  Herbert, Harry and Ron went back to St. Charles Community College EM48qt to finish out the day by working Zack and John in Dow before they moved to Eagle Roost at Pere Marquette State Park, EM48rx.

It was a fun, long day.
