KanOkla Link Repeater System info can be found at the bottom of this page
Thank you for visiting my QRZ page. Since retirement this past year, I have actually found enough time to assemble a QRZ page. (There may to too much information here!) but I hope you enjoy it.
My oldest child is Miranda Allen KB5CST who is running for U.S. Congress in 2016 for the State of KS.
K0UO's, Kansas QTH location is on a wheat farm & ranch, near the center of the U.S.A. 160 km's (100 mi) WSW of Wichita, KS. Which is halfway between Wichita and the famous wild west cow town of Dodge City and just north of Indian Territory! On U.S.HWY 281 @ Mile 7, look for the big tower and FAA airstrip # (4KS), and see the QRZ map (No Zoning Laws, HOA's or CC&R's antenna rerestrictions out here in the High Plains of Kansas, where the Buffalos roam).
To confirm the QSO with K0UO, just use the QRZ logbook It was great to see many old freinds at Dayton and the Rocky Mountain convention at Keystone, Colo this year. I hope to see you at Quartzfest, Quartzsite, AZ in Jan 2017.
THE BIG PROJECT is on the Air: I'm working on the "Lost Art of Rhombics" building these at the Kansas QTH. The "KING of Wire Antennas" is a W1AW type Rhombic which is 550 foot per-leg and almost 1000' end to end. That makes it 4 Wave-Lengths long on each of the four sides or 16 wave-lengths total for 40 meters, this may be the largest 40 meter Rhombic antenna in current ham use, (TF4M put up a larger one at one time, K7YRV had nine up at on time which three were 1100', and in 1951 W6AM had one that was 1500ft). "Build it and the DX will come". The next and last antenna will be 5 wave-length on each side for 40 meters and is being built this summer 2016, this will be the main European work horse. The site also has two other 1000' Vee-beams, all on 75-90 foot wooden poles. The gain over my full size 2 element 40 meter, which is at 100 feet high is truly unbelievable! The ARRL Diamond Logo is in fact a Rhombic antenna. Now doing EME on 6 meters JT65 with this antennna on some moon rises. See more photos of the install at the bottom of this QRZ page
"The very best part of this hobby is the People that you meet, and the great Friendships that happen as a result", get on the air and meet some new friends. When all else fails, we hams will be on the air. Call CQ once in a while, you might be surprise who calls you back!
Breckenridge, Colorado in the photo below, is my other QTH. It is at an elevation of +10,000 feet (3200 meters) near "Baldy Mountain". K0UO loves making mountain top QSO's from the 14,000 foot Colorado Rocky Mountains. The Jeep 4 by 4 that I use, is equipped with an IC 7000.
Above: My Breckenridge, Colorado QTH @ +10,500 ft, this may in fact be one of the highest home QTH's in the USA! (See More info at K0UO/P on QRZ)

My wife is N0UO, my oldest child is Miranda KB5CST who is running for U.S. Congress in 2016. South Central Kansas Businesswoman, Miranda Allen, announces she is running for U.S. Congress. "We need "Beams over the Capital", She declares, “I’m running for Congress because career politicians serve themselves – not the people.” Miranda Allen will be running for Kansas’ 4th District Congressional District seat. Kansas’ 4th Congressional district is based in the south central part of the state encompassing all of The City of Wichita. It contains the entirety of Edwards, Kiowa, Comanche, Stafford, Pratt, Barber, Kingman, Harper, Harvey, Sedgwick, Sumner, Butler, Cowley, Greenwood, Elk, and Chautauqua Counties, along with part of Pawnee County.“I believe the people of Kansas want their Member of Congress to be an independent voice for them.”.
My son Jon is KD0DCO, Grandson Gavin KE0DAL, first cousins Marc WQ5Y and Mike W5ALZ and both of their wifes Roberta KF5HHI and Raqelle W5QLE. Amateur Radio is a great hobby; which after all these years, has not lost any fascination for me. I enjoy rag chewing and DX on HF. There is still something magic about bouncing a signal off of the ionosphere and having someone on the other side of the world respond.
MY OTHER HOBBIES OVERVIEW: Things that K0UO likes to do, are playing with the grandkids, flying, farming, driving corvettes, ATVs & motorcycles (Harleys & Moto Guzzies), jeeping offroad, prospecting, fishing, beer brewing, RVing, hunting, shooting (full auto class 3 guns), wildlife watching, and building antennas. See Mule Creek Hunt for photos of my hunting area near my QTH http://www.rsicorp.com/mule_creek/index.html
WORK OVERVIEW: As of 2014 I'm 60% retired, but the other 40% of the time that I do work, are doing things that I want to do! As Director of RSI Corp which is a Telecom-Technical and Safety Service Firm http://www.rsicorp.com with Two-way radio services (Icom & Kenwood radios) http://www.rfcomply.com/pc/products_services/comm_and_security/index.php) and other businesses ranging from Farming, Broadcasting, Oil & Gas services http://www.rfcomply.com/pc/products_services/environmental/oil_gas.php, Concrete Walz Brand of concrete fencing and Oil & Gas radio tower services http://www.concretewalz.com/, Walz Broadcasting http://kpak.net/ BoarderLine Electric http://www.borderlineelectric.com/ and RSI "Defense Technical Information" Group, focuses on defense telecommunication command and control used by the militaryhttp://www.rfcomply.com/pc/products_services/dtic.php Also see this fun video of RF lighting up the light https://www.youtube.com/watch?v=wTohQTl1bAI or cooking a hotdog with RF! https://www.youtube.com/watch?v=BVn5OJX1EGw

Above, Main St. USA in Kiowa, KS. Why not Fly to work? In a Cessna P-337 pressurized twin, the rear engine is runnning and I'm at the controls, in front of our old warehouse-office buildings at 1310 Main St. Kiowa, KS. By the way this is a real photo, we do it "our way" out here on the ranch! Note there is a 200' tower with a tri-bander on this site too, you can see the guys wires.
My real Airport is just west of the Kiowa, KS QTH, and is now about 3000FT long with the displace thresholds, but watch out for the towers and oil wells!
HAM RADIO OVERVIEW: K0UO started into ham radio in 1967 as WN5UTO (working on 50 years of hamming fun), then WA5UTO, in the 1970s I moved through all the classes, and passed all the code tests 5, 13, and 20 WPM, (all administered by the FCC) also I held the old call from British Honduras of VP1KW (now in Belize I'm V31KW) and Military Auxiliary Radio System (MARS) call of AAT6PS. K0UO is a J-38 straight key guy, holds a 1st Class Radiotelephone license (now the GROL) and the Commercial telegraphy element 4 which is 25wpm, and I am authorized to conduct FCC commercial radio exams for the GROL. This video is of the 1st no code hams!!! http://www.youtube.com/watch?v=NJGrlUXCZzc (have fun with it)!
Life ARRL, ARRL Volunteer Consulting Engineer for the Midwest Division, ARRL District Emergency Coordinator (Amateur Radio Emergency Service ARES), 160-6 WAS, DXCC, VUCC, and Royal Order of Wouff Hong, The Rag Chewers' Club, American Legion Amateur Radio Club, Society of Broadcast Engineers and K0UO sometimes contest from the Bunkhouse see "KB0HH" on QRZ. Ragchewer 1st and DXer for fun! BE PATIENT AND RESPECT YOUR FELLOW HAMS, AND CONDUCT YOURSELF TO EARN THEIR RESPECT. I have worked 44 states terrestrial SSB/CW on 144MHz from my KS QTH (one night a few years ago I was lucky enought to work 14 news states on MS) .
MAIN RADIO EQUIPMENT OVERVIEW: ICOM-7800, IC-7600, IC 7300, IC 7000s, IC-7100s, IC-7200 (The new IC-7851 is not on order yet!) Kenwood 990, Kenwood 2000s, (just sold the Yaesu FT DX 5000 MP), Flex 6700 and an Elecraft K3 (I'm not a big fan of this radio, the display and over all "feel" is not up to other radios, tx audio on some units are poor and I'm on the second K3 now, in fact the IC 7300 is an overall better rig). Amps in current use are two AL-1500 two-holers (2 x 8877 tubes), Icom PW-1, and a Tokyo HL-2500. Some of my mic's are the Neumann BCM 104, AKG's classic C12 , a few RCA's, the Goldline and others. Vintage equipment that is on the air, Johnson Ranger & Valiant, Gates 1K, Hammarlund SP-600, R-390 and many others. When I go "SK" my XYL will have fun getting all of this junk out of here!
Above: Some of K0UO's old Vintage equipment
On my RV and RV Trailers I use a 40 meter dipole with a pushup mast and I'm now trying "The Power Whip" (by KV5A Dave Sparks 505-730-8698) on top of the ladder.
Antennas are the most important part of your station: Most of the places that I have lived do not have tall trees, so an important part of my antenna projects over the years have been able to build and climb towers safety (I have in fact climbed broadcast towers which are nearly 2000 feet tall). Also I have been teaching many types of "Telecom Safety" and "Technical" classes since the late 1990's, (over 15,000 students live or online through RSI Corp http://www.rsicorp.com ).
New Tower: In 2010 a new 195 foot Rohn model J rigid tube bolt together export type (Rohn 55 size) tower was installed to replace the Big Tower. On 160, & 80, I use full size 1/4 vel's four Sq's hung off the tower and the guy wires, for 40 a full size 2 el vertical phase beam @ 100 ft and on top a 8 ele-long boom log for 10Mhz- 50MHz and Bi-Directional 2 Wire Beverages .
There used to be allot of aluminum in the air at the KS QTH, but after numerous ice and windstorms I decided there had to be a better way. There's really not much to see here now, just one tall tower and a few blocks from the house you might notice some tall utility poles. Unless you know about wire antennas you probably wouldn't notice the full-sized 1/4 wave 4 SQ for 160 and 80 m's hung off of the tower. Or the cables between the utility poles which forms the Vee- beams and rhombics.
The old Tower in the main photo, was 10 feet wide, with the work-deck @145 feet. The center tower at 190' tower with a prop-pitch motor ground mounted using a M2 RC2800 control box, (FCC tower reg number is for 195'). 1000' to 2000' long rx/antennas the big tower had the these antennas, 60 meters 1/2 wave dipole at 150', 40-10 8 el M2 log beam at 168 Feet.
In the past K0UO has tried EME and JT65 on 2 meters using four M2 5w's Long boom az/el 170Ft, 220 M2 30' boom beam, four on 70cm M2 33' Long Booms 172', 902-1296 six foot dish 140Ft all VHF and UHF antennas are feed with 1 5/8 hard line.
The Kansas QTH can be run "Green, Off-Grid" using Natural-Gas from our own oil & gas wells which power a 20KW full time back-up generator!
Below: I love to off-road in my Overland Jeep, with an IC-7000, 500 HF amp, Scorpion screwdriver antenna, Kenwood TM-D710, APRS, Land Mobil Radio, Airband, and VHF Marine. Colorado and Western U.S.A. off-road trail Fun!
Above, is an O2 Skymaster called "Miss Belize", the plane has HF/VHF & UHF equipment and was showed in "Dec 1996 QST". Miss Belize was flown by General Walz in an effort by the Belize Government to bolster and fortify relationships with the United States. “Miss Belize” has flown at over 100 USA and caribbean air shows and at numerous US Military Bases Air demonstrations in the 1990s. Note that my Belize ham call "V31KW" is also the Airplane's tail numbers, see more photos on QRZ @ the call V31KW.
When in Belize my call is V31KW, my Internet remote station is at the Belize Defense Force base, Ladyville Belize (INTL. Airport). I have run AIRMOBLE 160-70cm from Belize!!
Above: Life's too short for QRP! Out here on the ranch big antennas and real power is the game!!! Above is a Ameritron AL 1500 Amp, but this one has Two Tubes (8877 x 2) it is a Bunker Buster. Why so much power??? Think about it, my antennas are more than 1000 feet from the shack, which is more than 3 db of feedline (that is one half of the power). Remember 1500 W PEP is the maximum output from an amateur station 97.313, where you measure that power from the transmitter, is not defined. But common best management practices allowed by the FCC and used by broadcasters, is anywhere along the transmission line and adding in line loss. The new regulations for the 60 m amateur band specifically states maximum ERP at antenna. FCC OET 65 outlines very clearly for RF safety, it is the power getting to the antenna, outlining the line losses as part of the equation. (I run 100 watts 90% of the time, most reports are 59).
This Two Tube 8877 amp puts out a "2 by 2" signal, “Too Loud and Too Strong”!
Above: This view is looking from the 100' level on the old tower and up to the top, the work deck level was at 145ft. 10 foot wide and set in 27 yards of cement.
The New Tower is 195 ft FCC Tower number #1216715, just east of the Walz Airport "4KS".
One of my BIG TX high power units, look at the 3" hardline!!!
The Big Rhombic Antenna Project
Above: The base of one the feed point poles, which are about 25-30 meters tall. Note the open wire "Tapered Feed" system wires coming down the poles to provide a broadband match on HF, About 1 meter (39") wide at the top tapering down to 3 " at the feed-point. Rhombics have a high input impedance of about 600-900 ohms, so it's not a trivial matter to achieve a match to 50 ohm coax while still retaining the very broadband nature inherent to the terminated rhombic. This led me to do some research on "tapered lines", the result of which is shown in the pictures above. After several prototypes, I settled on the tapered 2-wire transmission line shown here which is a modified exponential taper. I use 2" spacing open feed line using number 12 copper wire. The antenna is 550 foot per-leg (4legs) and almost 1000' end to end. That makes it 4 Wave-Lengths long on each of the four sides or 16 wave-lengths total for 40 meters, this may be the largest 40 meter Rhombic antenna in current ham use. The site also has two 1000' Vee-beams as part of the system. The next and last antenna will be 5 wave-length on each side for 40 meters and is being built this summer 2015, this will be the main European work horse.
Vee Beam above is 1/2 of a RhombicK0UO has 2 long Vee Beams
Above: Rigging the antenna cables. Note my tallest ham tower 195 feet is 1/4 of a mile away in the photo!
Above: The poles are almost 36" wide at the base, on the main east-west continental US antenna four of the insulators are from the famous W 6 AM rhombic farm which was located in Southern California.
Above: It took a few days to do all the layout work One of the control boxes for changing direction
It took days of tree removing to get through the wooded creek bottom area, using my Cat Dozer
This project so far, has used 1000 foot of 7/8" 50 ohm hard-line, 1000 foot of control cable, 1000 foot of 600 ohm feedline and will used over a mile and half of 3/8" cable for the antennas, when complete!
How do the Rhombics preform?
A detailed modeling analysis of these rhombics has been done, but the on the air tests and QSO's show the real power of this antenna. With more than 2200 feet of wire in the air “The RF Gotta-Go-Somewhere”.
Open-wire feed lines are connected to each end of the antennas ends, bringing these to a central point in the middle this allows switching in a termination resistor or a balun to switch directions. The antennas also works very good in the "Bi-direction" mode.
Think about this: The Maximum usable frequency (MUF) is important for determining the best HF frequency to use in communicating between two locations and most amateur radio operators understand it. But for general amateur radio work, maximum usable angle (MUA) is probably more important than maximum usable frequency. Maximum usable angle focuses on band availability, the types of antennas needed to take advantage of band openings, and the skip distances that can be expected. The maximum usable frequency equation for communicating is Fm = Fo / (sin Ae) The main lobe elevation angle depends on the configuration of the transmitting antenna. When I designed these antennas, MUA to DX locations from my KS QTH had to be the main part of the that design.
Above: The Plot is for a 3 wavelength Rhombic per side. K0UO's antennas are 4 waves on each side for 40 meters or 8 waves on 20 meters.
Did You Know: That during the 1950s and 1960s, when the USSR and the US were in the midst of the so-called "Cold War." Fearing that Soviet bombers could home in on radio signals to find their targets, the CONELRAD (CONtrol of ELectromagnetic RADiation) system went into effect from 1957 to 1962. Did you know that hams were required to (1) monitor an AM broadcast station at least every 10 minutes to be sure it was still on the air; and (2) shut down, if broadcast stations went off the air. In the event of such an emergency, key 50 kW AM stations would move to either 640 or 1240 kHz to broadcast emergency information. The stations on each of those frequencies would go on and off the air in a continually varying sequence, while all carried the same audio to provide continuous information to the public.
Couple of things on good operator etiquette
If you hear a station in QSO, please don't just jump in if you can't hear both stations, (unless you have an emergency). It's very rude and disrupts the QSO, the best practice would be to wait until the station signs that you cannot hear.
Don't instantly give somebody a bad audio report, unless you know how they sound in person, (this would not apply if they have humming, buzzing are cutting out). As an example, I have a very very deep voice, I know I could tailor my audio with highs but it would not be me!
KanOkla Intertie Repeater System is one of my first cousins Mike Walz, W5ALZ projects, he was the founder of this system (Mikes, "Dream" has turmed into a very wide area system), see the Map at http://www.statelineskywarn.com/coverage.html
