McKinney Amateur Radio Club June 2015 President’s Message May was a busy month for MARC and June looks like it will follow suite. Ham Radio in the Park May 2nd was well attended and provided a lot of good experience for our members. The Smiles Charity Event May 24th was also well attended, both by MARC members in a communications support role and by the general public. And we didn’t get wet this year! Everyone there agreed they are going to return next year to support this fantastic event. We were one event short of previous years – the Richardson Wild Ride, a bike ride and fun walk/run that we have supported with communications for a number of years. It was canceled by its organizers. June brings HamCom and Field Day – both big events! HamCom (June 1213) has moved this year to the Irving Convention Center. We will not be providing staff and the CSU for talkin as the local clubs will now handle this detail. Also, there will be no parking collections by clubs this year (although we will have to pay for parking). We will have out traditional flea market tables for club members to move their surplus gear via consignment. The Field Day event is the largest ham event of the year encompassing all of North America. We have a lot of new members who have not yet experienced a field day. If this is you, you really need to come be a part of this event on June 2728. See articles in this newsletter for additional details as to time, place, and opportunities. Be sure you’re a member of our Yahoo group as I will be sending out a daily Field Day Message via that medium starting about June 10th or so. And on that topic, if you’re not signed up to receive the Yahoo missives, please see my entry in last month’s newsletter for more information on signing up. We will take a break from our first Saturday class on June 6 as McKinney voting is continuing on that weekend – we’ve been preempted on the classroom again. Since there are already two major activities in June, it seems reasonable to take a Saturday off. So – relax and get ready for an exciting June. See you Tuesday, June 9th for an important monthly meeting. We’ll be voting on an update to our Constitution and Bylaws and planning for Field Day.

Respectfully submitted, Kathy Barnes, KF5ZKX Secretary, McKinney Radio Club Amateur Hello everyone, This is your field day update. June is fast approaching and we still have stuff to do. In case you did not know we have moved our event to a new location. Melissa site fell through, but the City of Fairview has welcomed us back with open arms. We will be at the same location as last year, behind Fair View City Hall at Stacy Rd and Highway 5. AK5SP has spent a lot of time on the doodle pages not only to sign up logging and contacting, but for everything else that is needed. Dave has added to these doodle pages, what you have already signed up for from those paper sign up sheets. So if you don't remember what you said you would do or bring, or if you want to sign up to bring or help out, go to http://doodle.com/zssdhzpscu4iue2r to sign up or check to see when your are logging/contacting, use this link. http://doodle.com/xex6zxv4ay2inavg Tracy N5UNX , Mike N5GNU, Bob K5CRX have offered to help with setting up the computers. We will have both the CSU and Claude's KE6EJG RV there too. But we do want to do more operating outside this year so we can be seen by the public. The committee is busy trying to get the final things arranged. Paul White K5PTW is going to be the instructor for the Scouts again this year. Thank you Judy for arranging this. It is looking like we might have a full house. Andy W5KZJ has been getting calls from local scout troops as to how many can come. Dan W5FRT is also working with some scout troops, So we set a limit of 30 scouts. Bob K5CRX has offered the use of the club microphone and speaker for him to use. We will reserve a full area just for them so not to interfere with his teachings. Paul has also said that each of the scouts will need to make at least 1 contact on the radio so he can sign off on their badges, so we will need to help the kids out as they come to the stations. Scouts will be on site from 1:003:00. We will have a fox hunt or two, hopefully the scouts can join in on all this too. Hands on class or tables set up with such stuff, our Elmer's will be on site for those who will be taking their test and want some help with that. First Aid class will be available too. Thank you Peter AF5TR for arranging this. All hams should know the basic skill of first aid so come and join us. This class will overlap with the scout a bit, but they should be getting on the radios around this time. First aid starts 2:00 4:00 VE testing will be on site again this year and will go from 4:306:00. Cont on pg6 McKinney Amateur Radio Club Page 5 Cont from pg5 Dinner will be at 6:30 The Marking's will bring their grill down and grill us some hot dogs. All are welcome to attend. Bring extra food to put with the hot dogs come hungry and maybe some extra drinks too. Someone asked about Antenna's at the meeting, we will use what ever we did last year to make thing eaiser for everyone. Mike W8CM and Dave K5EEN have taken on the role of safety officers for our event. So if you see anything that is not safe, please let them know. I have made contact with the local radio station 97.5 and they are willing to do some promo for us for field day. So tune in to 97.5 they are here in McKinney. Thanks you Robert AF5RA for that pointer. Also I have contacted Larry Mowry with channel 11 about coming out to do his weather broad cast with us, or just to meet us, as of today I have not heard back from him. Over the next few weeks we will beging to buy the supplies for dinner and breakfast. If any one has offered supplies for set up or to use druing our filed day, you may bring them to the next meeting if you wish or if you are planing on helping set up you can bring them then. I am still working on a few more items that were asked for at the May meeting. So for now 73 everyone and hope to see you all at Field Day if not before. QSL Cards and the Stories Behind Them Part 1 of 9 by Scott Laughlin/n7net I'm sharing a few of my QSL Cards. Each is a cherished milestone, reflecting something I've never forgotten. Some were dumb luck, others I had to work for. At the present time I've selected nine. There may be more—memory is illusive My first transmitter was a Heathkit DX20. I bought it assembled, well used, and already scratched. There was no matching receiver, nor was there a VFO. Without a doubt, I could have fabricated VFO. I had the schematic, and Radio Shack still sold things of interest in those days. But I was too busy trying to achieve 13 WPM to get bogged down with fabrication and troubleshooting why it drifted, and whatnot. Instead, I mailed an inquiry to JAN Crystals in Florida, in search of a fortymeter crystal that would oscillate in the novice section. They responded with three options: 1) add an additional sum of cash totaling more than the initial costs of the crystal and shipping combined and they would put a rush on it; 2) mail them a smaller sum and they would probably have it ready in two weeks; or 3) mail them no additional fees and they would get around to it in a timely manner. Well, I was trying to keep a low profile around the house. This was a hobby, for crying out loud, how much I spent was being closely monitored. So I selected option 3 and waited. After some five weeks it finally arrived and it worked. My receiver was a Lafayette something or other. It looked like a Helicrafter, but that was where the parallels stopped. The fortymeter amateur band was crowded into a microsection measuring about .375 of one inch. Zero beating with a transmitter was not going to be easy. However, I had some ancient HF experience dealing with the basic, antiquated communications equipment found on board the C54s—1942 through 1945 models, like those used in the Berlin Air Lift. (It was no wonder these old aircraft required a radio operator. The copilot certainly didn't have time to monkey around with that stuff). So it wasn't as impossible for me as it could have been. So I was on the air with one frequency, 7.1xx MHz. I read a lot of novels while waiting for someone to drive by, as it were. I'm not sure what month I earned my technician ticket and my present call, N7NET, but on 28 December 1989 I connected with Frank, W4AF, in Belmont, California. We exchanged signal reports and personal information. Much to my surprise he was also operating a DX20 with the exact same crystal. I asked him for a card, but he told me he was too old to order QSL cards. However, much to my pleasure he made one with a ballpoint and mailed it to me. See QSL card on page 7 McKinney Amateur Radio Club Page 6 HamCom Flea Market Reminder Remember that once again we will have a table in the flea market area to help club members sell unwanted items for only 10% of the selling price. Also club members are welcome to help staff the table for a while in order to give the table staff a break. HamCom Primer I know we have several new members and some long time members who may never have been to HamCom. With that in mind here's my short guide to getting the most out of your Ham Com experience. A few days before HamCom go out to http://www.hamcom.org/ and download the Brochure. Look it over. It will give you the times and locations for presentations, vendor locations, parking, anything you would want to know. Make note of presentation times that you want to attend and schedule your time around those. Make a list of things you may be looking for and check them off as you find them. Plan on getting there early. There may be a vendor you want to talk to. Some vendors will have a line of folks wanting to talk to them. Be patient, you will get your turn and remember the vendors want to talk to you as much as you want to talk to them. Now let's talk used, flea market equipment. For example, you may have been to some of Bob's electronics classes and decided you want some test equipment. You find what your looking for but don't know if it's a "Deal or a Dud". Don't be afraid to ask questions. Smell the unit (yes, I said smell) to see if it has a burnt electronics smell but keep in mind it could have been repaired. Look for dent's, scratches, are all the parts there or will you still need a probe for example. Remember, you have a large support group behind you. If your just not sure, find one of the club members and ask them to look at the unit with you, I know we will be happy to help. Keep in mind however that the end decision is yours and let the buyer beware. (that being said I have always had good luck and everything I have purchased has been as advertised). Don't forget to have a good time, meet people and make friends. Phillip Littlefield, KB5YIA Smiles Charity Concert 2015 Another Success The Smiles Charity Concert is fast becoming a tradition in McKinney. (Nine years running!) And, for a second year, the annual Memorial Day weekend event was attended by many MARC Communication Support volunteers. Whether it was operating an active simplex net from 2pm 11pm, monitoring shuttles and offsite parking lots (3 this year), directing traffic flow at all Adriatica entrances, or assisting concert patrons and ensuring a safe event for all, MARC volunteers performed with the utmost professionalism and dedication. Hats off to all those that stepped up: Andy Barnes (W5KZJ), Noah Chalker (KE5VQL), Bob DeVance (K5CRX), Robert DiGioia (AF5RA), Clark Hansen (AE5WD), Mark Holmes (WD5JXC), Bradley Jensen (KF5ZAW), James Kemp (KG5FVM), Jim Kuch (KD5JK), Patty Marking (KG5AEL), Dave Marking (AK5SP), Dan McKinley (W5FRT), Danielle McKinley (KE5LGY), Kenneth Spock (KF5TXL), Bill Vining (N5YZ), Robert Wakeman Cont on pg8 McKinney Amateur Radio Club Page 7 Cont from pg7 (K5WRE), John Wing (AE5ZK), and Peter Witheford (AF5TR). It is your dedication to public service that makes allvolunteer events like this possible! A special Thank You goes out to Dave Piekarski (K5EEN) for transporting the MARC CSU and generator to and from the event, and always making certain that the CSU is in a "good to go" state. Thanks Dave! Be sure to check out the Smiles Charity website (www.SmilesCharity.com). Proceeds from this allvolunteer event go to build a house in Collin County for a local wounded veteran and their family. There are many inspiring photos, videos, and articles from this year's event, as well as from year's past. Perhaps this will inspire you to step up and volunteer for next year's Smiles Charity Concert. After all, much FUN was had by all! (A side note: Check out the photo of Dan's (W5FRT) guitar signed by headline act Rodney Atkins. Pretty cool, Dan!). To all those that helped this year: Well done! And, THANK YOU! Ham Radio in the Park another Success On Saturday, May 2nd some 20 MARC members descended on Bonnie Wenk Park on Virginia Parkway in McKinney to operate both CW and voice, participate in a dual foxhunt, and partake of some freshly grilled hot dogs. After setting up a canopy that would be temporary home to three radios, setting up portable antennas, and providing power the operation was on! Thanks to Scott, N7NET, for being our hero CW operator with a 20 minute CW QSO with a ham in Ohio. Shortly after launching the radios, the foxhunt began. This one was a bit unusual as there were two foxes running simultaneously and on opposite sides of the park. A number of our members took advantage of the time for training in foxhunting with teams going out in groups to track the elusive foxes. As everyone began to get hungry, it was discovered that there were no matches or lighters to start the fire for cooking the hot dogs. After Brian, WA5M, had headed for a local store to find a lighter, Andy, W5KZJ, arrived back from foxhunting sporting a butane fire starter! So – all was not lost! The hot dogs were done on time and everyone who wanted to do so ate their fill. Following pack up and cleanup, everyone went their respective ways – somewhat tired, but full and glad they had participated in the event. Bob, K5CRX June Raspberry Pi User Group Meeting After taking a one month break for Hamvention, we're back strong in June and "if the creek don't rise", we'll have the rescheduled presentation on designing and laying out a daughter board for the Raspberry Pi, presented by Kip Moravec. The next Raspberry Pi User Group meeting will be the 3rd Saturday of June, on June 20 in the usual room, ECSS 2.410, at the usual time from 10a to 3p. As that date draws near, please visit http://brandenburgtech.com for more information, including maps. McKinney Amateur Radio Club Page 8 Sending messages, pictures, and video from a Raspberry Pi. This article will show you how to send messages, pictures, and video with the raspberry pi to your cell phone. To use the information in the article you will need something like a gmail account that can redirect your email message to your phone. First thing we will need to do is load some additional modules into the raspberry pi. Again aptget is your friend for doing this. Load the following modules. Utilities for sending electronic mail sudo aptget install mailutils ssmtp Utilities to handle shell archives. sudo aptget install sharutils The mpack program encodes a named file in one or more MIME messages. The resulting messages are mailed to one or more recipients. sudo aptget install mpack A Multimedia package for performing many manipulations on multimedia files like AVI, MPG, ... sudo aptget install y gpac You may also need to load uuencode too, depends on your pi distribution. Used to convert binary code to ASCII characters for easy electronic transmission. sudo aptget install uuencode By installing the ssmtp module, you have the ability to send email. First you need to setup the ssmtp configuration file. You will need to setup at least five lines; mailhub, hostname, Authuser, Authpass, UseSTARTTLS. sudo vi /etc/ssmtp/ssmtp.conf Add your mailhub information. Here is my mailhub line. mailhub=smtp.gmail.com:587 Add your system hostname. Here is my hostname line. hostname=bplus The Authuser, AuthPass, and UseSTARTTLS you may have to add to the file. Here are my lines, the data for user and password are not accurate. [email protected] AuthPass=password.2 UseSTARTTLS=YES At this point save the file. One thing to remember when sending MMS messages, they have a size limit of 600,000 bytes. Pictures and videos have to be smaller than the size limit. Text messages can be larger as they can be broken up into several messages. Now to have some fun. Connect your camera to your raspberry pi. We are now going to take a still picture and send it to a cell phone. raspistill o image4.jpg w 300 h 300 mpack s Image4 image4.jpg [email protected] Now lets take a video, convert it to mp4, and send it to a cell phone.

One of the major drivers at least in my property situation is that it had to fit in my back yard which already has my HF Vertical, VHF J pole and two trees leaving very little space. So off I headed to the Internet to start my search for a home brew design. There are a lot of NVIS designs out there for 80 / 40 meters but they all need space which I don’t have. After lots of looking and reading I came across a one page article by BUDDIPOLE (The BUDDIPOLE QuickFix for NVIS http://lib.store.yahoo.net/lib/buddipole/nvis2008.pdf ) on how to turn a standard BUDDIPOLE into an 80 / 40 meter NVIS antenna. So using the information from the BUDDIPOLE article as a starting point here is my version of a BUDDIPOLE 80 / 40 meter NVIS that will fit in a small typical city lot back yard. Needed parts: Standard BUDDIPOLE mast, tripod, antenna arm (2), VersaTee, and Coil set Qty 2 – 3/8 x 24 stainless steel bolts 1/2” long Qty 4 – 3/8” ring terminals for 18 gauge wire 50ft RED – 18 gauge insulated wire 50.5ft BLACK – 18 gauge insulated wire Qty 4 – Dog bone insulators or similar (can be made out of a cutting board) Qty 2 – 2ft nonconducting stakes / posts (1 x 2 works well) Qty 24ft of antenna guy rope (550 parachute cord works just fine) Qty 2 – small stakes for the guy rope As required color contrasting heat shrink to mark the wires for easy adjustment The ultimate goal is to create an offcenterfeed dipole that when erected 9 to 10 feet off the ground in an Inverted V configuration will yield a NVIS antenna for 80 / 40 meters depending on the wire set used. Figure 1 is a depiction of the final antenna configuration. The first step was to create the insulators for the wire ends and attach the guy ropes. I fashioned 4 insulators out of a cutting board that I had in the materials stash and attached 6 feet of 550 paracord to each one. 4 are needed as we are building 2 antennas an 80m and a 40m unlike the BUDDIPOLE design which was a single long wire for both bands. Figure 1 BUDDIPOLE NVIS The second step is to cut the antenna wires to length and attach 3/8” ring terminals. The BUDDIPOLE design was for a single wire for 80 and 40 meters wound on a kite winder for adjustment. I decided to take a different approach and make one set of wires for 80 meters and one set for 40 meters. This approach meant that I didn’t have to hunt up kite winders and it is easier to adjust. You will want to use different colored wire for the two sides of the dipole that you are building, since they are different lengths, to aid in identification. You can use the same colors for the 40m and the 80m since the lengths are quite different and easy to identify. 80m RED – 30ft 80m BLACK – 31ft 40m RED – 16ft 40m BLACK – 19.5ft Now attach each wire to an insulator / guy rope assembly and secure by folding 2ft of the end over and wrapping it around itself. This is done so that the antenna can be adjusted close to the center frequency that you which to operate on. I used a piece of Velcro next to the insulator and at the loose end to keep the wire from unwrapping and to allow future adjustment. The wire / insulator / guy assemble should now have the following dimensions from the ring terminal to the insulator. 80m RED – 28ft 80m BLACK – 29ft 40m RED – 14ft 40m BLACK – 17.5ft The next step is to assemble either the 40m or 80m antenna and adjust the length for your desired operating frequency. So assemble the tripod, mast, VersaTee, antenna arms, and coils as you normally would for a BUDDIPOLE dipole. Attach the 40m or 80m RED wire to the RED coil and the 40m or 80m BLACK wire to the BLACK coil using the 3/8 x 24 bolts. DO NOT use a wrench to tighten these. They only need to be finger tight. If you use stainless steel as I did, to prevent corrosion, you will damage the threads if you use a wrench and no anti seize compound. The 80m antenna coils should NOT be tapped. The 40m antenna coils should be tapped as indicated in the table at the end of this article. Extend your mast to 9 to 10 feet. Decide on the height you are going to use and stick with it because if you change the height you change the center frequency of the antenna. I used 10ft because it was easy to determine, 2 lower mast sections fully extended and the 3rd mast section extended the length of my 2ft stake equaled 10ft. Use the 2ft stakes to elevate the wire ends off the ground and secure with McKinney Amateur Radio Club Page 10 the guy lines. The wires from the coils to the 2ft stakes should be tight enough so they do not sag. I would suggest that you mark your coils with nail polish or paint at the appropriate tap points for 40m for ease of assembly during later employments of the antenna. Now comes the time consuming part so that your antenna is easier to setup and use later. As I mentioned earlier my goal for this antenna is the NTX ARES HF Nets. The 80m net is on 3.860 MHz and the 40m net is on 7.285 MHz. So I started with my 80m setup and adjusted the wire lengths until I established minimum SWR at 3.860 MHz using my Youkits FG01 graphic antenna analyzer. As you go through this process change the RED and BLACK wire lengths in equal amounts, if you shorten the RED 6 inches shorten the Black 6 inches. During this process I found that I needed to use my BUDDIPOLE adjustable BALAN at a setting of 2:1 to reduce the SWR below about 3. Once you have located your desired operating frequency wire length, mark each of the wires at that location with contrasting heat shrink. This will make it easy later to return to this frequency. So since I didn’t just want to use the antenna at a single frequency I installed heat shrink at 6 inch intervals on the 80m wires and 1 inch intervals on the 40m wires and spent the afternoon constructing the tables below for easy setup of future operations. Consistency in setting up your BUDDIPOLE NVIS antenna is the key so that all the hard work you put into developing a table similar to the one below will pay off in the future. If you are consistent with your setup the markings will at least get you into the infield of the ballpark for your desired operating frequency and your antenna tuner should be able to handle the rest. Or if you have your antenna analyzer handy you can check the center frequency and adjust your length if needed. Once you have all your markings and measurements complete store each set of wires and guys in a labeled zip lock bag and you are ready to deploy or just setup for occasional use in the back yard.
