Being Prepared - Kansas City Areaby Robin, W0FEN
Being prepared begins with knowing which threats might effect your area. The primary threats in the Kansas City area are from nature, but there are others as well. The natural disasters are Tornadoes, Flash Floods, Lightning, and Pandemic. The human made disasters are chemical spills/explosions, collisions between human controlled devices, mechanical failures of manufacturing or transportation.
The first group being natural in cause come in a yearly pattern. The 'normal' tornado season runs from early spring to early fall. This is also the season of flash floods which are precipitated by heavy rains which are often accompanied by lightning. The main problem with recurring threats is that humankind becomes accustomed to them and does not take warnings as seriously as they should. A pandemic of the Flu could occur because too few took preventive shots or the shots were not prepared for the imminent threat. The Flu is an annual occurrence and 100 years has passed since it was a worldwide crisis which causes less fear.
The human caused threats are almost the opposite. Most people are unaware of the threat or assume that since nothing has happened that the risk is extremely low and is therefore under rated. The preparation for these is general and difficult at best. The types of disasters I am thinking of include a riverboat taking out one or several bridges. A large train derailment of caustic substances in a populous area. These types of disasters if occurring at commute times could affect large numbers of people.
As Amateur Radio Operators we understand we have duty to be 'more prepared' than the average citizen. A good friend has gone to the level of becoming an Instructor for CERT.

ANTENNAS ON 7.190 AND 14.287 MHZMy experimental Mag Loop Project, the rest of the story.by Tom, AB5ZJ
I started experimenting with Mag Loop antennas after encountering a Ham from Arizona, Rich - K8NDS. His signal was the only one I could here at that time on my Gap Vertical. After the customary exchange of gear and antenna, I asked him, "what do you mean Mag Loop?" His explanation excited me to find out more.
Over the next couple months I read all kinds of ham articles relating to mag loops in general, and Helical Mag loops specifically. Then, I took the plunge and designed on paper how I wanted to build my antenna from scratch. I decided my antenna would cover at least the 40m to 10m bands. I chose to use 3/4 in dia. copper tubing made into a 39 inch dia. circle based on calculations for Mag Loop design I found on the Internet.
Mag loop specs; (see pic right) main loop pipe diameter size is 3/4 copper flex tubing. Loop diameter is 39 inches. Feed loop is 7.5 inches. Loop is 3ft off ground. Capacitor is VVC 7pf - 350pf @35kv. I Used 1 1/2 pvc pipe for rigid construction and stand support. It is turned by a RCA VH126R TV programmable antenna rotator controller from the shack.
My additional plans are to tune the VVC with a stepping motor controlled by an Arduino connected to my FT-5000mp. Right now I manually tune it. The 5 gal. bucket is filled with 50lbs of sand. When I'm out in the field doing portable I put a small stake in the ground and place the PVC pipe below the rotor on the stake. It takes about 2 minutes to lug the antenna from my truck to the location and set it up. another couple minutes to connect the 50ft of coax to the rig. I pre-tune the antenna before I break it down. If I need to change frequencies I tune it on the spot with my RigExpert AA-600 analyzer. A good antenna analyzer is a good tool for tuning this type of antenna.
How has it worked so far? I have consistently received very good signal reports from S5 to S9 or more. I compare it to my Gap Challenger vertical, and often find it equals or exceeds the verticals performance. Many times durning receive I've been able to rotate the mag loop antenna to pick up a signal the vertical could not hear.
So far I've logged calls from all around the U.S. And Canada, and Europe, such as Slovakia, Finland, Scotland, and South America. All my over seas signal reports have been S6 to S8. Whenever I mentioned I am working a ham on my experimental mag loop antenna, their comments are not unlike mine when I first worked K8NDS. I'm finding the majority of hams I work have no idea such a antenna exists, so I always encourage them to research the subject on the Internet, as there is a surprisingly large group of hams already experimenting with them.
I am having a lot of fun building this antenna, and plan on building others with different specs for different bands. Because of the success I've had, I plan on making a mag loop my main antenna. But if your have restricted space, or have HOA restrictions, making and using a mag loop antenna is a wonderful way to get on the air. despite such restrictions.

ASCRA ON THE AIR AND IN ACTIONEcholink - W0SHQ-RWith thanks to Jim Craft, AD0AC, Doug Shaw, WA0EMX, and others we now have Echolink available through W0SHQ-R. It is routinely used during the Sunday afternoon 40 meter and 20 meter nets. It can be accessed from anywhere via the Internet. Many use a free smart phone application to connect to W0SHQ-R system. Others can connect from desktop computers or via their handi-talkie, mobile or fixed site amateur radio station. In addition to smart phone applications, there are free applications for PC, Mac, or Linux which are readily available.
Echolink is available to all license classes and makes it possible for any licensed ham to join in the on the air ASCRA activities. We will be encouraging past Spectacular licensed hams to join us via Echolink if they do not have an HF station. Indeed, even if they have an HF station, Echolink allows them to connect even when the band fails to cooperate.
The recent contact with Alex, KM4DWM, in Australia is the perfect example. With Echolink and W0SHQ-R it is now possible to organize a schedule or even a net based on this amateur radio VOIP technology.
Use your two-way radio to connect to Echolink via a local repeater or download and install software on one of your computer devices. Once the software is setup and your are registered, try connecting to W0SHQ-R and calling CQ. You will be heard on the Independence, MO 146.73 repeater and may get a response from any of a dozen ASCRA hams in the Independence area. Or, try connecting to the W0YO-R system via Echolink. That will allow you to be heard in Lamoni, IA and on the Graceland University Campus.
Remote Base at W0SHQYou can now operate W0SHQ as a remote base. Jim, AD0AC, has been working hard to make W0SHQ available as a remote base. To start using W0SHQ as a remote base, download and install the W4MQ software. Once configured contact Jim, AD0AC and verify your license and coordinate for a user name, normally your call sign, and a password.

Being Prepared - Kansas City Area, cont.
CERT or Community Emergency Response Team certification is a real plus as understanding how the 'system' of emergency response works. I encourage all reading this to investigate and signup for the training.
In the KC Metro area a overarching organization called MARC [Mid-America Regional Council] has taken on many projects for it's area that would never have happened if not for MARC. I was working for a two-way radio company in KC while it was installing 42 911 answering systems. That is not 42 operators but each of the 42 was between 1 and 25 operators. I do not know the entire number of operator positions that were installed.
As a Chief Engineer at a Radio station, I was involved with the operation and execution of the EAS weekly and monthly tests. This requires coordination between stations and law enforcement and NOAA. Now that Amber alerts are part of the system the Highway Patrol or State Police in most jurisdictions is responsible for originating these. NOAA has been responsible for the weather alerts for many years.
Before I took on the responsibility for the most recent radio station, Holly and I took the SKYWARN training for tornado spotters. I am no longer current in my certification for spotting. Due to our location, we were able to drive to the nearest NOAA site. There we became the liason between the Skywarn spotting nets and the Weathermen at NOAA. We were NOT the Net Control operators. We were the Hams who passed the info from the Net Controls to NOAA forecasters. Sometimes the NOAA folks had specific inquires for the weather spotters. Interesting, since I knew how Radio/TV Stations handled the information at the other end.
As a Radio Engineer I and other Engineers had concerns about getting to transmitter or studio sites if there were to be a 'martial law' situation.
The local SBE [Society of Broadcast Engineers] Chapter joined MARC several years ago with the intent of getting them to issue ID Badges for Broadcast Engineers to be able to get to their sites in order to ensure their stations were on and able to pass critical information. The status of the badges is still in limbo because every first responder also desires an ID. First responders include Doctors, Nurses, EMT/Paramedics, Law Enforcement, and many others. Each group from sanitary sewer system operators to ICU and ER staff does need to have a ID/Badge to get to a location in a time of crisis.
The program started by MARC has evolved and Amateur Radio Operator CAN be a useful part in the Kansas City area. Both the Red Cross and the Salvation Army now require Hams to take a very short on-line course to become a volunteer. Depending on the courses taken the Ham becomes a Radio Operator 1, 2, or 3. The Red Cross then knows what capabilities the Ham has and can assign them on that basis.
Each hospital in the KC Metro has an Amateur Station installed. There are Hams that have pledged to go to these hospitals should a crisis arise.
I encourage each ASCRA Member to investigate any activities that perk your interest.

I have been working with a group on 7.168 MHz for about 15 years. Now that I am in De Leon Springs with 90 foot tall pine trees I have been tesFng various wire antennas. I started with the ZS6BKW antenna that Mike, KM0S introduced me to. It has worked beNer than regular dipoles, 43 foot verFcals and more recently, a full size 1/4 wave verFcal hung at the 70 foot level from one of my tall pine trees.
In my group on forty the best antennas are beams. But I don’t have one of those up yet. The most popular antenna is a dipole made out of coax. Dave, KF4RO, provided the following instrucFons and drawings for building such an antenna. I ended up buying a Double Bazooka cut for 40 meters with an 80 meter trapped component. I have been tesFng the antenna for the past few days. This antenna finally beat the ZS6BKW. That is not surprising. What is suprising is that from on the air reports, using an A/B switch with the antennas hung at similar heights, the Double
Bazooka antenna was dramaFcally beNer than the ZS6BKW computer modeled G5RV.
VK3CPC reported a +2 S unit advantage for the Double Bazooka. W4QDN, 16 miles from me gave it a 4 S unit advantage. WW3A, two miles from me gave it a +10 db advantage. The ZS6BKW antenna was not even close.
Last week I compared a ver%cal 1/4 wave wire antenna and they were close, with the ZS6BKW having a slight, but consistent advantage. As the distance to the repor%ng sta%on increased the ver%cal seemed to do be^er. But with the report this morning from VK3CPC I am ready to concede the ZS6BKW has finally been beat by another antenna.
I will keep both antennas, using the ZS6BKW as a reference and all band antenna, and the Double Bazooka as be^er antenna on 40 where it has a pleasant 1:1 match and my only true 80 meter antenna where it also achieves a 1:1 match.

President's Notes by Robin Cross W0FEN
Having recently moved and everything in my shack is in a jumble I checked into the 20M net from my front yard this afternoon. I decided that I
needed a better antenna to get into the 20M net so yesterday I measured out about 70ft of copper wire that had been my 160M horizontal loop antenna for the last 8 years or so. The 70 Ft is from the formula of 1005/F. This is for a loop antenna. For a regular dipole it would be 468/F. I reused the PVC sweep elbows from the loop to raise the corners into 2 trees in the front yard. This was a fast move so I used things I had on hand to get the antenna finished. The 4:1 Balun is one I had from a loop antenna I had purchased and later sold. The large orange device is a DPDT knife switch I ordered from China. I bought several of the a few years ago. I used them to disconnect the home brew ladder line I was using to feed the 160 M Loop during thunderstorms. I used this just so that I would have screw terminals to
clamp on the antenna wire. The loop was to be a delta shape but was hanging too low so I hastily added another corner and made it into a sort-of rectangle. The antenna is up but now I needed coax to feed it. I had the leftover of a 100 Ft purchase of RG8X but with no connectors on it. I rummaged around some more and came up with crimp-on BNC connectors for RG8X. Now I was in business. This is in the front yard between two fairly tall trees. Right now my IC-746pro is in the sunroom by the back door. But my mobile and backup rig an IC-706MKIIg is in my vehicle. I scrounged some more and come up with 2 BNC to PL-259 adapters, So I've got everything I need. I stretched the coax over to the rear of the vehicle and procured a lawn chair from the rear patio and I should be all set for the 20 M ASCRA Net. The coax was pulling the Rig so to keep it stationary I wrapped it around the hitch in the back of the vehicle. A little after 3 CDT I called WB2UJL who gave me a reasonable signal report. The rest is history.
More on the order of what this column is about, someone suggested that ASCRA should have the preamble to our Nets posted on the website. So for the last two weeks or so several of the Board of Directors have been working on this via email. I also would like to see a published Net closing. After taking many comments a small AD HOC Committee is working on this. Speaking of which I as yet do not know the results of the recent Board Election. As soon as this happens we will have our Annual Board of Directors meeting. We have several items on the agenda already, but if you would like to attend in person or via phone or on-line, let us know. As always Board meetings are open to ALL Members. That is because you are the most important part of ASCRA.
Your humble servant Robin Crossw0fenPresident, ASCRA

It is my pleasure to introduce Larry (Butch) Fleming. He was a year ahead of me in high school and my Elmer. I built my first CW transmitter and modified an old AM broadcast receiver by adding a beat frequency oscillator for 455 KHz (BFO) in order to work him on CW from his house to my house, several blocks apart. Always a service oriented guy, Butch remains active in Ham Radio and enjoys tinkering and doing those projects others may have little interest in. Butch recently relocated from Redding, California to Kingman, Arizona. Listen for him on the 20 meter ASCRA net. This article is about one of his projects.
220 Living Room Repeater by Butch, W6DY
I had a 440 repeater in northern CA and it saw little use. It was an exercise for me and another project
to get through a winter. I brought the pieces with me and will re-accomplish it here this winter.It was portable and I would set it up
during field day and do a cross band repeat to the 2M club repeater back in Redding. I would let them know at the site near Mt. Lassen and it would be used quite a bit. The fun part was linking and always caught them off guard when the club repeater ID’d through my little portable machine. My cross band repeater is nothing more than a Alinco DR-635 I use for comms in my travel trailer. I would also use it while traveling with a 440 handheld in the truck and it crossbanding to 2M from the trailer. Best distance was 150 miles simplex mobile into Oregon one
trip. Super DX!
This 220 machine was another winter project. It uses two Alinco DR-235 Mk III radios with a ID-O-Matic IV controller. I used the data I/O on the radios for audio/COR/PTT. Super simple. I finally found a dulpexer a few weeks ago, and that was all that was holding up this project. Now to get some of the club members to start using it. There are several that use 220 simplex, and they are all located in/near town. I also acquired a autopatch, so just maybe......
Never underestimate a small repeater, even it you don't have an ideal location. I'd recommend 440 and make it suitcase/ice chest portable. Duplexers are as small as the radios and easily available. You can sell the idea to your local emergency services people just by setting it on a table in front of them. If you have a hospital close by set it on the roof with a ground-plane antenna. Figure battery capacity for a few hours with the ability to plug it in included. Piece of cake and useful too.
Butch - W6DY~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~An4que Sta4onby Jim, K7NCG
The picture below is a picture of my 'anFque' staFon. The unit on the le^ is what started it all. A friend of mine, Bruce, got the Warrior amp a^er the high voltage secFon had been torn out of it because the power transformer was no good. The chassis, front panel, and cabinet were in great shape and I couldn't bear to see it tossed out. So I rebuilt it for him as something to keep busy. So a^er it sat in my garage for a few weeks I brought it inside and started cleaning it up. Took everything off of the chassis and removed the chassis top. I took it out to the garage and sanded it to remove all of the aged pit marks. A^er pu`ng the final cage assembly all back together, it really looked preNy good. I started trying to come up with a power transformer combinaFon that would work for the 811A’s but everything was either too high or too low of voltage.
a Repeater and an An:que Radio Sta:on

Then we found a power transformer for it on Ebay so Bruce bought it and I put everything back in that was stock. It has the original recFfier tubes, swinging choke, and bleeder resistor. It's all stock
except I put in an antenna switching relay and low power relay driver circuit so it could be switched behind any new rig. Works great with 600 to 800 waNs out with weak 811A tubes.
So then last March, we take the Warrior amp to a local big swap meet to try and sell. Neither Bruce nor I need another amp. While there I was wandering around looking at stuff and I saw the Mohawk receiver si`ng on a table. It was turned on and playing and looked in great shape. Very nice and clean. I remembered about the one I had years ago and thought it might be fun to have one again. But that would just create problems because I would want a matching transmiNer and good looking Apache transmiNers are ge`ng hard to find. Couldn’t find the owner of the table for a while but kept thinking “I hope he wants too much for that so I won’t buy it and have to find a transmiNer”. A^er finding the owner and talking to him, he offers it for $100. I couldn’t pass one like that for that price so I bought it. Now I had the problem of finding a matching transmiNer.
So later I’m walking around the swap meet and in one of the cubicals I see a big Heathkit green box. At first I thought it was one of the VHF transmiNers and walked on. Later I decided to invesFgate more closely. As I approached the unit, I soon realized that it was a Marauder transmiNer. It had a price sFcker on it that said $275. I’ve always wanted to play with a Marauder for some reason. It was Heathkits most difficult kit to build with over 300 hours of assembly Fme if I remember correctly. This thing looked preNy decent. I asked the guy standing in the booth about it and he said, “Well, the owner is out to lunch right now but he doesn’t want to haul it back home. Check back in a liNle bit.” So I’m thinking to myself, if
he doesn’t want to haul it home, the price is at least down to $200 in my mind. A^er making several trips back and the owner sFll out to lunch, the other guy says “he’ll let you have it for $150.” I couldn’t get my wallet open fast enough. I brought the receiver and transmiNer home. Bruce insisted that I also take the amp. I connected the Marauder up to my variac and powered it up slowly. While doing that I took a paint brush and started sweeping the dust off of the chassis. It was starFng to look really nice. A^er about 20 minutes, I was up to the nominal voltage and saw that I had high voltage and everything was looking good. I plugged it into the wall, connected a dummy load, and tuned it up. I had about 120 waNs out. This thing was working! I later took all the knobs off and cleaned them up. I cleaned the front panel and put the cleaned knobs back on and it looked like new. Further cleaning revealed that all of the tubes except the finals sFll had a clear label of Daystrom on them. A^er a minor alignment of 40 meters, this thing work great. And Bruce decided to sell me the amp for what he had into it which was the power transformer and 3 tubes.
I soon discovered that the receiver had some very serious design problems in it. The AVC circuit had no delay to it and had no adjustments. You could hear background staFc noise between dots and dashes. So it got modified. The ANL circuit only caused distorFon on AM so it needed changing. And the product detector was as much a distorFon generator as it was a detector. All of the modifica%ons were pre^y easy and greatly improved the performance. I decided to just live with the driW.
So there's my an%que sta%on….about 232 lbs. of Heathkit boat anchor. But it’s been fun working on it and using it.
Jim -‐ K7NCG~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~I believe I s%ll have a Lysco 500 CW only transmi^er from about 1952. It is the oldest opera%onal piece of gear I own. I use to use it during my Ham Radio classes at the Great Plains Voca%onal and Technical School in Lawton, Oklahoma.

Show Me Your Shackby Ed Briley, KD0MEI
I work the ASCRA Nets on HF, No Echolink. My station set up is pretty basic. I like to keep things simple.
Here at KD0MEI we run 100 watts, usually out of an ICOM IC-7200, but sometimes we use at ICOM IC-718.The antenna tuner is an MFJ Versa Tuner II (MFJ-949D). The antenna is usually a 31 foot vertical. A piece of pipe was driven into the ground so that about 18 inches is still above ground. A four foot Army surplus fiberglass tent pole was then placed over the pipe. Hose clamps hold an MFJ 31 foot telescoping mast to the tent pole.
A 32 foot piece of 16 gauge speaker wire is attached to the telescoping mast. A DX Engineering radial plate is on the ground under the tent pole with sixteen radials of varying lengths on the ground held in place by landscaping staples. The vertical radiator is fed through a 4 to 1 balun which is also attached to the tent pole. It seems to work quite well on 80 thru 10 meters.
I also like to experiment with various antenna ideas. I have a 17 foot telescoping stainless steel whip which is fed through an Alpha Match from Alpha Antenna of Greenwood, MO. I used one of those jaw type of mounts to attach it in various
places. I had it mounted 4 feet above ground on another of those Army surplus tent poles with four 17 foot above ground radials as a counter poise. That worked very well from 20 through 10 meters WITHOUT the Alpha Match. With the Alpha Match if did pretty well from 40 thru 10 meters. It also performed well mounted on a tripod that extends to about six and a half feet in height. Those same four radials made up the counterpoise when I used the tripod.
Next experiment will be to rotate the jaw mount 90 degrees and mount the whip on the top rail of a four foot cyclone fence. I'm hoping the fence will act as a counterpoise.
A few years ago I ran coax to a downspout and drove the gutters as an antenna. I worked both the 40 meter and 20 meter ASCRA nets that way for a while.
One of the guys in the Raytown (MO) Amateur Radio Club seems to be able to work the South Pole on 160 meters with a paper clip as an antenna. He is W0AO and he must get the credit for the gutters as an antenna idea! At the Raytown club's hamfest in 2012 he set up a rig just outside the entrance, used a fishing pole to hold one end of a wire 25 feet or so up in the air and ran the other end of the wire directly to his tuner. Within minutes he was working stations in Europe!
Here's hoping you can use some of this for your In Service artlces.

Skywaves - by Doug Shaw WA0EMXMy Skywaves contribution is very brief this issue so Robin can share his new antenna farm experiments. We will begin to address the June 2016 USA and World Conference and any related pre-conference meetings planning in my Skywaves column and other articles in the coming issues of IN SERVICE. We will be needing many volunteers if ASCRA is to have a visible presence at these gatherings. Please send any suggestions, questions or concerns to me by Email or give me a call on my land line 816.358.6856. Please send me preferences for time and day of week for an ASCRA stand-alone Echolink Net, and if you would like to help as net control/facilitator for it or for our HF Shadow nets on Sunday.
Lots of good content this issue. Thanks to all who contributed.
