The Guadalupe Valley Amateur Radio Club will be again holding Field Day at WQ5C’s QTH on River Road. We’re planning on running a home station on emergency power, along with a temporary station, and possibly a “Get On The Air” station reserved for inactive hams. The highlight will be a KE5DFK brisket masterpiece on Saturday evening and Gary K5GST’s prize winning apple pies & cupcakes. All hams & their families are encouraged to attend.

We emphasize FUN over competition.

HB 242, passed by the 82nd Legislature, would have prohibited sending or reading text messages while driving. However, Gov. Perry vetoed HB 242 on June 17, 2011.
That means the only State-wide prohibition on the use of a cell phone while driving remains the prohibition on the use of a cell phone in an active school zone. Various cities, including San Antonio and Austin, do have local ordinances that prohibit “texting while driving.” These ordinances are not affected by the Governor’s veto of HB 242 and remain in effect.
The Governor issued the following statement explaining his veto of HB 242:

Since we weren’t happy with any of the local radio club offerings for Field Day, Bob, W2IK, along with Krissy, KD5YTN, have planned a “Minimalistic Field Day” this year. We will be operating from a local park (to be determined), bringing only the simplest of equipment, unlike previous operations where a massive amount of equipment was brought. To be sure there are no problems, all equipment, cables and supplies will be given a through check out the day before Field Day. The only added supply will be a toolkit just in case. This means ONE radio, ONE coax cable, ONE multi-band “inverted V” antenna (W2IK design), ONE telescoping mast, etc. The radio will be powered by twin deep-cycle batteries charged by banks of solar panels. ONE 10×10 canopy will shade both the operating area and cooking area where a propane grill will cook the meals. W2IK will be operating 1Batt, STX so if you hear him, please give a shout out. Logging will be accomplished by a net-book with “SQUIRL Field Day Logger” program. As always, a paper log will provide back up. Pictures will be taken of the event to be posted at SA Hams.

I was invited to help out during the Texas Water Safari http://texaswatersafari.org at the Luling Texas (Zedler Mill) Dam location, where the San Marcos river flows (key word “flows”) over the dam and under the bridge.   I brought my son, David KD5MTJ along to help as well.   When we arrived shortly after 1pm by following MaryAnne’s excellent directions, we found the group already on the air behind the Zedler Mill, on the north side of the river bank.    Stan KA5IID, Alfred KG5QW and MaryAnne N5MYN were already set up and raring to go, assuming any canoes showed up. 

The first canoe team showed up around 3:30pm, and the last one just after 10:30pm.  There were 103 canoes at 8am, but only 94 made it past our point, which was 46 miles down stream from the starting point.

The three of them had been doing this particular location for many years, so they knew what to expect, and didn’t snicker too much when David or I asked questions or made suggestions.  The food was great, thanks mostly to MaryAnne & Alfred I suspect, and we had lots of scenery to watch while waiting for the canoes.  Mosquitos weren’t as bad as I had expected, the flies were worse, especially when Alfred & I returned back with several pounds of great BBQ brisket for dinner.

As the night wound down, waiting for those last few canoes, we started to pack up.  I went to retrieve my van which had been parked outside the gate all day to make it easier to run errands, only to find out that the park ranger had locked the gates early!  Using my trusty Android phone to Google up the phone # for the Luling Police Department, we called for help!   The very professional and police police officer arrived promptly, and found out his master key wouldn’t work, because the parks guy hadn’t locked it in a manner that would allow the city’s lock to open the gate.   Several calls thru the police dispatcher resulted in someone eventually showing up with the proper key.   The officer left the gate unlocked, and we called him back when we had gotten all of our vehicles and equipment out of the Zedler Mill park.  (Nice park by the way, worth the trip out from San Antonio to see it.)

I took some videos and some pics to share below.  The videos are posted both on Youtube.com under “2011 Texas Water Safari” using my account of “lbesing”, and on my Facebook page (marked to be shared with anyone, not just my friends).

A FEW TIPS FOR ANY FIELD DAY OPERATION  – I’ve posted these a few years ago, but I think they should be repeated.

1. When setting up antennas within close proximity: If you are using wire antennas such as dipoles, and they run parallel to each other there will be interference on your HF operating bands in the form of hash so arrange them at right angles to each other and at slightly different heights. If you use wire antennas such as dipoles, try to stay away from trap dipoles and use full length antennas instead.  You may also wish to run your dipoles in different configurations such as have one as an “inverted V” and another as a sloper, etc. An antenna cut to the exact band you are using will decrease interference to and from other bands. Do not use compromise or “all band” antennas. On HF, stay away from vertical antennas as they receive too much man-made noise from sources such as generators, etc.

ICE_Bandpass_402x2. When operating within a tight area, as required by FD rules, it also pays to use “band pass filters” such as those manufactured by ICE. I have a full set of these HF filters and they work great. They are only about $ 38 per band and drastically reduce interference from your other operating posts. If your pocketbook can’t afford them, use coax “stub” filters. The lengths of these and how to build them can be found at: http://www.k1ttt.net/technote/k2trstub.html They are simple to make and easy to use. Both systems have been used by the major DXpeditions all over the world with great success. On HF frequencies make sure each operating station is properly grounded. Do NOT use a common ground for all your operating posts.

3. Make sure that each operating position has a laminated chart of frequencies that can be used under your station’s or club’s operating license. Watch out and don’t operate too close to the band edges. (remember: no one “owns” a frequency)

4. If using computer logging, always have paper logs and scratch pads ready to use in case your computers bog down or crash. (ever use a “dupe sheet”? Don’t know what it is? Find out!)

5. Whenever  I operate either in contests or operating events, I find it advantageous to camp out (remain on) a frequency rather than tune around (hunt and pounce). Remember that propagation conditions will change so stick with it even if you think the band has died or other stations appear on your frequency that weren’t there earlier. That’s just how propagation works.

6. Keep your calling frequency active by calling CQ often. Don’t wait! Leave a gap of only 4 seconds between calls or stations tuning by will miss your call and other stations mfj434bwishing to camp out may take over your frequency. In events such as FD, it also pays to use an automatic voice unit such as MFJ 434B “voice keyer”. (Cost is about $170.) If you can’t obtain one, use a cheap electronic memo reminder and just play back your pre-recorded CQ while holding it close to your microphone. This form of “acoustic coupling” is an inexpensive way to save your voice. I have used both methods over the years with success. Keep your calls “short and sweet” using ITU phonetics ONLY. Don’t use any “cutesy” phonetics.

7. If you are lucky enough to cause a “pile up” (several stations calling you at once) answer the easiest one to hear first. If you can’t make out complete callsigns, ask for the station with the easiest partial call to reply. The others will wait. Do not get flustered.

8. Ignore jammers. Do NOT bother answering them.

9. Have your station’s callsign and exchange info posted in large letters at your operating position in case you get a bit tired so you won’t forget and announce your own call by mistake.

10. If possible, bring your own headphones to make your life easier and to cut down on ambient noise from your area.

11. Talk in a loud, clear voice. No need to shout as it distorts your signal. Speak in to the microphone at an angle.

12. Pace yourself, drink plenty of fluids and let whomever is in charge know when you need a break. Do NOT be a “mic hog” as other people may wish to gain the experience of operating.

13. Learn a bit about propagation characteristics for each band and time of day before you come to FD.

14. If there are enough people, have someone do the logging for you. This way they will learn to copy callsigns under less than perfect situations and will make life easier for you. A “double set of ears” makes it easier to operate and log. It might even entice non-hams to get their license.

15. If you want your FD to be more successful, WAIT until all members have arrived before deciding what amount of stations you wish to put on the air for the event. You can always change bands, even with a 1A station. Years ago one club I was a member of decided to operate 20A ! That’s 20 stations operating. The only problem was there wasn’t enough people to man all the stations for the length of FD, so we were stuck at times with 10 stations we couldn’t use. You can’t change your exchange once the event starts. Talk about bad planning.

16. Flag all coax runs, power cords and antenna guy lines with brightly colored caution tape so no one walks into them or trips over them.

17. Never assume you’ve “worked them all”.  In 1991 a pair of inexperienced ops came out of the 40 meter SSB tent claiming they “worked the band dry”. I told them they hadn’t and taking another op to log for me, in 30 minutes I worked an additional 60+ stations on that “dry band”. Lesson learned: There are always other stations out there to work.

18. Know the rig you are operating by reading each radio’s instruction manual. By doing so you’ll avoid problems and make more contacts.  Be especially careful of the filters in complex radios as they could filter out wanted signals. Keep your operations simple so the next person assigned to your station won’t get confused twisting and turning knobs!

19. Turn off all gear during refueling of any gas generators. Use proper saftey procedures so voltage spikes won’t harm your radios. This means to turn off your radios BEFORE the generator shuts off and wait until it reaches operational speed before turning your gear back on. You can get voltage spikes during the shutting off of the generator and the start up cycle. Use care when refuelling the generator and NEVER gas it up while it is running. A gas spill even when the generator is off but HOT can also spell disaster.

20. Learn , but most of all : Have fun. (also, have your license handy… it’s an FCC requirement)

   With the start of Summer, June 1st marks the beginning of “Hurricane Season”. It’s been predicted to be a very active period. We hope a hurricane doesn’t strike our area, but we must be ready in case it does.Many newly licensed hams have joined the amateur radio ranks just in time to become useful communicators should an emergency caused by severe weather arise. There is always a need for trained emergency communications personnel, but this is especially true in the areas which are more likely to be impacted by a hurricane, those regions being the Atlantic and Gulf Coast areas. However, it takes more than just a license and a hand-held radio to make you a useful part of emergency communications. It also takes preparation, training and practice.

Preparation requires each communicator to develop a cache of supplies to help them in fulfilling their communications duties.

There are various websites you can rely on as basic lists in building your “go bag” of supplies. I realize that most of you are on limited budgets regarding the purchase of additional rigs or other related equipment, so improve on what you have with the addition of a better antenna system and upgraded power sources. Keep in mind that you won’t be able to “run home” to get something you’ve forgotten.

There are NO second chances with emergency communications during a hurricane.

 Reminders –

If by choice or by wallet your only rig is an HT: The battery pack that came with your HT is NOT enough during a deployment. Make sure you have additional power in the form of extra batteries and a power supply. You should have enough “portable power” to last for at least 4 days of operation.
 
The “rubber duck” antenna that came with your HT won’t do much good during an emergency. In terms of Effective Radiated Power (ERP) a 5 watt HT with it’s standard rubber duck antenna at shoulder height actually radiates only 1.5 watts ERP. (The stock antenna that came with your HT is what’s known as a “negative gain antenna”) Clipping the same HT on your belt would attenuate the signal an additional 20 db, meaning the ERP would only be about 15 MILLIWATTS!  This is why you need a “gain” antenna at a decent height for emergency communications deployment. You should have a 17 inch flexible whip antenna and at the very least a roll-up “J Pole” antenna with coax. If you are really serious, you’ll need an emergency VHF antenna.  This is a very light weight, portable antenna that is packaged in a 48 inch tube yet deploys to a height of over 16 feet. It is easy to build. It exhibits gain. It can be used with an HT to greatly expand it’s range and can also be used with a mobile rig for indoor or outdoor use.
  
MAPS, MAPS, MAPS.
 
Always document what you do. Keep accurate notes and communications, marking times of each. This will help in reviewing later.
 
You’ll also need to refresh yourself on the basics of emergency communications. The better armed you are with information and the basic proper gear, the better you’ll be able to do your communications task.

Time to test and inspect all your equipment. Replace weak re-chargable batteries and check out all cables for wear or fraying. Make some test transmissions to see how well your equipment will “hit” the various local repeaters that are used during emergencies and put them in your radio’s memory bank. Perhaps it’s time to buy that deep-cycle marine battery as you might need it to power your mobile rig indoors during a power failure. (Don’t forget that emergency VHF antenna system as mentioned above)

Hopefully you are a member of some emergency communications group in your area. Time to attend meetings and on-air lessons in earnest. Ask questions no matter how trivial you think they are because others will probably benefit from the answers. If your group is smart, they’ll have a small drill or two. Keep your group updated on any new gear (radios, antennas, etc) which would make your deployment more valuable to your team.

Keep on your toes when a developing storm starts it’s march across the Atlantic. Follow the path and look at projected paths at: WEATHER UNDERGROUND website. It’s a good source of info during hurricane season.

PREPARE your family for the hurricane season.  Train your family members and build a “home bag” so they won’t have to do without should severe weather occur in your area.

Make sure that if a hurricane is within 300 miles of your home that you keep all your vehicles’ gas tanks “topped off” and buy extra, extra batteries for any flashlights used by your family. At the same time, be sure to monitor your EmComm group’s repeater frequency for updates or possible “call outs”. Make sure that you also have “wide-range” repeater frequencies in you rig’s memory. If you have a General or above license, try to have a working, portable HF station which also includes an NVIS antenna system for reliable short-range HF communications.

Keep every battery charged and have all equipment gathered and ready.

Be an active member in your EmComm groups activities so you can all be “on the same page”. Hopefully, your emergency communications group has in place an honest, comprehensive emergency plan for it’s operators and has trained it’s members with something more than “table-top” drills. FIELD DAY IS NOT ENOUGH.
