DIGITAL MESSAGING IN SUPPORT OF EMERGENCY COMMUNICATION

 By Bud Thompson, N0IA


Ham Radio to-E-mail messaging is a functional reality of the early 21st century and will supplant the conventional 25 to 30 word manually-transferred NTS-formatted messages used for 'Record' traffic to support served agencies during communications emergencies.  

This fully automated system permits much more information/data to be transferred error free while minimizing the number of licensed hams required to get needed information from originator to addressee.

Free-formatted e-mail messages have no practical word/length limit, and can be transferred between and among digital ham radio stations within the "Last Mile" (where conventional communications are disrupted or overloaded), and can 'bridge' the last mile to where the messages may be processed as Internet e-mail. 

E-mail has become universal in business and government and requires little training to support EMCOMMs (Emergency Communications) incidences; non- ham licensed typists (including emergency response agency personnel) can be employed for data/message entry as the 'editor' is as familiar as Outlook Express or other commonly used E-mail client programs.

Where applicable, a single ham radio digital station with only one licensed amateur as control operator can support several e-mail workstations/computers on a LAN enabling served agency workers to simply use Ham Radio to E-mail to any network digital station and any E-mail address when the internet is not available.

Served agencies will appreciate this system as it (1) permits more information to be exchanged in less time, (2) is fully accurate after initial data entry, (3) gives the agency control of content, and (4) provides a good degree of security from casual on-channel monitoring by those not involved in the event or exercise. 

With proper coordination and planning the future can see every County Emergency Operations Center (EOC) in the state represented on the layered digital network enabling ham radio e-mail messaging between and among them as well as with local tactical stations (i.e. Incident Command, mobile/portable sites, served agencies, etc.) 

A proposal is presently being evaluated for as many as seven hospitals in three contiguous counties in Central Florida to be represented on the network.

FCC CHANGES RULES TO PROMOTE BROADBAND OVER POWER LINE

Adopting a Report and Order in ET Docket 04-37, the Federal Communications Commission (FCC) approved revisions to Part 15 rules to specifically regulate the deployment of broadband over power line (BPL) technology as an unlicensed service. The announcement was made on October 14th at a meeting of FCC Commissioners.

FCC Chairman Michael Powell called it “a banner day” for communications in the US. He said, BPL promises “ubiquitous service to all Americans at affordable rates.” Powell conceded that BPL will affect some spectrum users--including “all those wonderful Amateur Radio operators out there.”

Powell said the FCC has taken great care to ensure that protections are in place to allow Amateur Radio to continue.  But he implied that the FCC must balance the benefits of BPL against the relative value of licensed services such as ham radio.

He gushed “let me underscore the potential for the American economy is too great, too enormous, too potentially groundbreaking to sit idly by and allow any claim or any possible speculative fear keep us from driving this technology and drive America into the broadband future.”  That implication is not good for Amateur radio operators.

Three Commissioners, including Powell, specifically mentioned the concerns of Amateur Radio operators at the open meeting. They expressed assurances and hope that the new BPL rules will adequately address interference.

One Commissioner emphasized that “life and safety” radio systems would receive priority protection from BPL interference through frequency notching and exclusion zones. Other licensed users such as hams would be protected on a complaint basis, “when and if interference occurs.”

A representative of the FCC Office of Engineering and Technology (OET), who outlined the draft R&O, acknowledged that Access type BPL devices “pose a somewhat higher potential for interference to licensed radio services than typical Part 15 devices” but added, “we believe the specific benefits of BPL warrant acceptance of a small degree of additional risk, and that this interference potential can be satisfactorily managed.”

ARRL has stated that while it doesn’t oppose BPL, proposed safeguards against interference to Amateur Radio operators are inadequate. It pushed for mandatory “notching” or filtering of BPL signals from ham bands. FCC proposed notching only for high priority services but not Amateur Radio.

The entire Report and Order will not be made public for weeks. Critical details on how interference is to measured and reported will not be known until the entire proceeding is publicized. So far only a public announcement of its action has been released by FCC.

RADIO OPERATOR CONCERNS ABOUT BPL

Four principal methods are currently in use to deliver internet broadband to consumers.  These include telephone company digital subscriber lines, cable broadband, non-satellite wireless and satellite delivery.

Broadband over Power Line (BPL) would be a fifth alternative.  Doubt exists among communications engineers about the ability to establish a feasible business model for BPL internet broadband service.  Thus far, the only deployment of BPL has been in small test areas. 

In general, Amateur Radio operators have no objection to broadband internet or BPL. Many operators use broadband internet to supplement their operation.  Their concern is that BPL interference potential to radio communications is high because unshielded cables are used for power distribution.  Stringent FCC-mandated protection is necessary. A speedy complaint resolution procedure must be in place along with adequate technical standards.

No such problems exist with broadband alternatives to BPL. These employ either shielded cable or use frequencies that are not likely to cause significant interference.

During BPL tests, sponsoring corporations were ineffective at filtering out interference to communications.  Response time to complaints was very slow.   When solutions were too time-consuming or ineffective, some test sponsors just started ignoring complaints.

HAM RADIO OPERATORS STILL IMPORTANT TO HURRICANE PREDICTION


By ADRIAN SAINZ
Associated Press Writer
 

MIAMI - Max Mayfield and his team of hurricane forecasters were poised to downgrade Hurricane Michelle to a tropical storm when they got the call from a ham radio operator.

A sailboat near the Bahamas was reporting 100 mph winds, directly contradicting satellite reports showing Michelle was losing steam and becoming disorganized.

Michelle had already killed 17 people as it blasted through Cuba, Honduras, Nicaragua and Jamaica. With the Bahamas in its path, forecasters had to decide whether to believe the satellite or the ham radio.

They chose the report from the ham radio, scrapping plans to downgrade Michelle and keeping Hurricane warnings for the Bahamas. Parts of the island grouping took a direct hit from the storm.

"The surface winds from the ham report really helped us immensely," said Mayfield, director of the National Hurricane Center in Miami.

Despite sophisticated technology that has made hurricane forecasting more accurate, ham radio operators remain a critical component, sometimes providing more reliable information than satellites and hurricane hunter aircraft to forecasters whose job it is to track the storms and warn people out of harm's way.

During the Atlantic hurricane season, radio operators in the United States, the Caribbean and Latin America team up to provide data to forecasters. And when the power is out, ham radio operators with battery power or electric generators are sometimes the only source of information from a storm-stricken region.

"No matter what the satellite says, no matter what the airplanes say, it's what's on the ground that counts," said Ham operator John McHugh.

McHugh helps organize a group of 40 ham volunteers in Miami who are activated yearly on June 1 for the start of the Atlantic hurricane season.

When a storm is 300 miles away from any land, they come in three-hour shifts to the center and field reports from other dedicated amateur radio hounds on reserved long-range radio frequencies. Ham operators transmit and receive valuable hurricane data such as wind speeds, pressure and rain amounts.

The data bounces to Miami, where it is digested by forecasters.

Surface information ahead of a storm leads to the most accurate predictions for where a hurricane is going and how strong it is. Ground data from ham radio operators reporting from the middle of the storm can verify maximum winds and pressure readings. After a hurricane, amateur radio provides damage reports and rain totals.

From his "fort-like" home in St. Croix in the U.S. Virgin Islands, John Ellis has an elaborate setup complete with transceivers, antennas and weather gauges he uses to measure weather conditions and communicate with the hurricane center.

Ellis, 59, has been through major hurricanes Hugo in 1989 and Georges in 1998, along with several other hurricanes and tropical storms. He's been in amateur radio for 48 years, starting off by helping civil defense officials track tornadoes in Johnson County, Kansas.

Many ham operators, like Ellis, can transmit when power and telephones don't work by using portable electric generators. Ellis has antennas that can lie flat on the ground outside - allowing him to transmit in the face of a hurricane's strong winds.

"The thrust is to give the hurricane center as much notice as possible so they can get their warnings out as accurately as possible," Ellis said in a telephone interview.

He and his wife have a set routine he describes as automatic - put up shutters, gas up the car, bring in the lawn furniture and ride out the storm. They can file reports with the hurricane center or relay reports from other ham operators.

"The house is very unpleasant when all the shutters go up," Ellis said. "It's dark and it's dreary and not a fun place to be in. It's a fort."

Ellis said the arrival of e-mail and the Internet in the 1990s has kept ham operators relevant to hurricane forecasting. The World Wide Web and 24-hour cable news stations have heightened the need for instant news, putting the onus on amateur radio for real-time reports when the power is usually out.

"During those first few hours, the ham radio is as important as it ever was, perhaps a little bit more so because of the need for news and the expectation of knowing what's going on right now," Ellis said.

The $20,000 setup at the hurricane center includes not only radios but also computers and fax machines that get data to forecasters. Most of the equipment is donated.

Hams are keeping up with technology in several ways. An instant Internet-based method of reporting hurricane data is being used by 200 to 300 people who don't own ham radios but live within 50 miles of the U.S. coast, have working weather stations in their homes and want to help the center's hurricane coverage.

They just fill out a form and e-mail it to the volunteers at the center.

Another program allows the National Weather Service to get instant year-round feeds from hundreds of computers connected to home weather stations which automatically communicate wind speed and direction, temperature and pressure every 15 minutes.

But it's during hurricane season when hams and other reporters of weather data are most prized by Mayfield and hurricane specialists.

"We're the ones who are actually there, in the middle of it," Ellis said.

DISCOUNT ELECTRONICS - A FRIEND OF NOFARS
By Mike Davis, N4FOZ


Walter Mooneyhan, just turned 81 years old and still runs Discount Electronics on a daily basis. He has seen the need to supply our area Hams with radios, antennas and accessories since many of the local "Shacks" no longer stock the needed items.

He began his business in 1970 at 54th and Pearl, by the railroad tracks, with a partner named Burton. Soon Mr. Mooneyhan took over the business entirely, but kept the Burton Company name. For many years thereafter, lots of people knew him as "Mr. Burton". He retired and closed the business in 1986, only to come out of retirement and re-open the business under the current name of Discount Electronics.

In 1995, Discount Electronics moved to its current location on US-1, about a mile south of Callahan, FL. He began selling more Ham radio gear in 1997 as part of his established 11 meter business. In 2004, seeing more need for a local store to sell communication parts , Mr. Mooneyhan began to increase his stock in Ham equipment.

So how does a small, local store compete with the big mail order houses and stay in business when many have closed? Discount prides itself in being able to get equipment through Commodity Buying. The means, he looks for a good value deal and only buys what he can at a reduced price he can pass along to the local Hams. Anyone who has been there to check prices knows the name of his store is correct.

Mr. Mooneyhan cites the excellent design, reliability and performance of Diamond and Comet Antennas. Yet, those antennas can be quite costly and hard to buy in small quantities. So he found an excellent "generic" manufacturer in Tram and Workman Antennas, who has cloned the antennas at a much lower price now that the patents have run their legal course.


Discount now stocks connectors, power supplies, wire, antennas, and all kinds of mounts and small parts. He is also a stocking dealer of ICOM and Yaesu VHF Ham radios. In the planning stages is the expansion of the store and the continued support of the Ham community.

Walter Mooneyhan feels Ham radio is alive and well, and has had a boost with all the publicity from Hurricane communication services. Being able to pick up a microphone and talk to many people at one time is still popular. He says someday he might retire, but until then, Discount Electronics will continue to serve the needs of Northeast Florida Hams.

SUNN BATTERY: A GOOD LOCAL SOURCE FOR HAM RADIO BATTERIES

By Mike Davis, N4FOZ


Sunn Battery, located at 1316 Adams St., near Myrtle and Adams St., in Jacksonville, has been a long time supplier of new and refurbished batteries for Amateur Radio.

After his presentation at the September, 2006 NOFARS meeting, I had a chance to sit down with Ed Corbett, VP and General Manager of Sunn, and talk about today's and future batteries that will affect all of our lives. But first a little about who they are and what they do.

Sunn Battery sells about every type of battery one could imagine. What is not well know is the fact that many popular batteries actually have greatly varied capacities and quality, even though they appear to be the same type and size. That is why many of us have found that getting a replacement battery or having a battery pack rebuilt yields a product better than the original equipment.

"It is an industry secret that many, for example, "C" size, batteries contain fillers that reduce the price, but also reduce the amperage output and quality", says Ed Corbett.

"The future looks very bright for the battery industry", Corbett added, "as there is a continued push to create lighter, more powerful sources of portable power in a given specification of battery." He sites the example of the smaller, yet longer lasting power of Cell Phones, PDAs, and portable music devices.


Ham radio can expect the trickle down effect of these new power sources with more durable and longer lasting batteries that don't have the problem of "memory loss", which is described as the diminishing amount of amperage a battery delivers over years of repeated charging/overcharging.

What is on the horizon? Since there is a big surge in alternative power for small electronic gadgets to battery powered vehicles, we can be assured that better batteries are on the way. There have been articles and rumors abounding about a new "Super Battery" that will be twice the power as anything in comparison. There is a lot of speculation about these batteries, but the signs point to a "Hydrogen based" power source, that could see some announcements late in 2007.

When that comes, it is a safe bet that Sunn Battery will be at the top of the power curve.

FCC APPROVES FIVE FREQUENCIES FOR 60 METER OPERATION


The Federal Communications Commission has approved limited Amateur Radio operation on five frequencies in a new 60 meter band effective July 3. ARRL and others had sought a new 150 KHz ham band in the 5 MHz. area. The band was opposed by the National Telecommunications and Information Administration (NTIA) which cited a possible need for the requested band by federal government users and proposed limiting hams to five specific frequencies for use on a secondary basis.

The five spot frequencies or channels are 5332, 5348, 5368, 5373, and 5405 kHz. The FCC has granted operation on USB (2K8J3E emission) only, with a maximum effective radiated power limit of 50 W relative to a 0 dB gain antenna--a half-wave dipole. The channels--each with a maximum permissible bandwidth of 2.8 kHz--will be available to General and higher class licensees.

Dave Sumner, K1ZZ of ARRL said "while the new amateur privileges at 5 MHz are not as flexible as we had hoped, we recognize that much has changed since the ARRL petition for rulemaking was submitted to the FCC in the summer of
2001. Federal agencies with homeland security responsibilities have renewed interest in HF radiocommunication."

END FED ANTENNAS AND APARTMENT DWELLERS

By Bill Larned, KA1WHT

Ham radio in an apartment complex involves creativity and compromise. Low profile operating is the art of getting on the air without alerting other residents or the landlord. Antennas are frowned upon in my apartment building. In fact, they're not allowed. “No radio or television aerials or wires shall protrude from or leave the inside of the apartment building,”my lease says. With no desire to quit operating HF CW or SSB, I threw an end-fed random wire into a tree anyway. At one end, I formed a loophole and weighted it so I could control the trajectory. The tree is 25 feet from my third-story window. I tune with an MFJ-949D. My best results are on 10, 12, 15, 17, and 20 meters.

A problem created by using an end-fed wire has been RF hotspots on metal objects in my hamshack. One ground wire is not enough to prevent this. My operating position is thirty feet from the earth, and running a ground wire that far to meet ground rods is not acceptable. On the higher HF bands, a ground wire run 30 feet or longer can radiate much like an antenna. Keep in mind that even when ground rods are feasible, running a one-quarter wavelength ground wire to them could create an impedance inverter. The part of the wire attached to the rods will be a low impedance, but the end inside the hamshack, attached to the ground terminal, will be high impedance, hence RF burns, and hotspots.

One way to reduce RF hotspots is to cut separate, different ground wires and hide them beneath a carpet or along the baseboards. The ends of the ground wires should be attached to the tuner and the transceiver.

The opposite ends should not be attached to anything.

Each should be a quarter wavelength for the band you want to operate on, and insulated, particularly at the ends, where the RF voltage will be the highest. Remember that ground wires radiate. They are the other half of the end-fed antenna. “The counterpoise [or ground wire] lowers the impedance and lowers the RF voltage at the transmitter end of the end-fed wire. However, this voltage never approaches zero,” says Jim Thompson, W4THU.

Below are quarter-wavelengths for each band I operate on. Some of the figures are rounded to the nearest foot:

10 meters………….….8 feet

12 meters……………..9.5 feet

15 meters……………..11 feet

17 meters……………..13 feet

20 meters……………..16 feet

Using a cold water pipe as a ground is bad for several reasons. You don't always know where the pipe terminates. It may meet other pipes. An extra long path to ground is bad news. In fact, the ground wire may radiate more than the antenna itself. Using an end-fed antenna places the operator in the middle of the antenna system. If the cable TV company and the phone company also ground their systems to the same cold water pipe, transmitting may cause a lot of RFI. Using a cold water pipe as a ground is a violation of the National Electrical Code, because of RF currents that appear on it during transmissions.

If you still encounter problems with RF in the shack, change the length of your antenna, and reduce power. Lengthen or subtract an eighth of a wavelength from your antenna. If all else fails, you can build or buy an artificial ground.

I remember when I was first licensed in 1990, and I tried to omit a ground for my first antenna. I was 17, and my father shook his head when he heard I'd gotten bitten by RF. He was a highway engineer, and had never been a ham, but he knew enough from having once been an electrician. Patiently, he handed me some wire, and said, “You know Bill, your hobby, if you're serious about it, isn't just about being an operator, it's also about being a technician and solving problems.” Those words still echo in my head whenever I'm tempted to skip an RF ground.

K4PYT LOGS ANOTHER ISS CONTACT

Jim Nipper, K4PYT made a quick, nice contact with the ham station aboard the International Space Station (ISS) on August 21 at about 1:20 pm local.  Jim made an ISS contact last year and regularly monitors for space station activity. 

According to Jim, "It has been a long time since I have heard voice activity on the Space Station.  I do hear the packet signals on almost every pass. "

 
He adds, "it appears that the hams aboard the ISS at this time make very few 'random'  voice contacts, as most of their QSOs are pre-arranged with school groups.   However, they do occasionally make random contacts on holidays and weekends. "
 
Downlink freq is 145.800 Mhz and the uplink is 144.490.   Jim uses an Icom 275H   multimode two meter transceiver and is assisted by  InstanTrack software.

PENSACOLA AFTER THE STORM

By Todd Lovelace, KI4ADK

Hello All! Todd Lovelace, KI4ADK here! I’d like to share an experience with you that I’ll never forget - going to Pensacola, Florida to help others one week after Hurricane Ivan passed thru in September 2004.

After experiencing more or less just the skirts of Hurricanes Bonnie, Charley, and Ivan - I realized just how fortunate that we citizens of Jacksonville had been. We certainly were affected by these storms, but reading numerous internet news accounts of what had happened in the rest of Florida convinced me that I needed to contribute some energy to help others that were not so fortunate.

I mentioned my interest to Duval ARES EC Ed Ramsey (KG4THS) and before I knew it there was an email from ARRL’s NE Florida Section Traffic Manager Dale Sewell (N4SGQ) in my inbox. Dale’s message included ARRL Tracker Number Documents (travel credentials to get me thru the police roadblocks!), a list of suggested take-along essentials, and the following map to help me detour around the storm-ravaged I-10 and US 90 bridges. There was also a warning that there was no gasoline available closer that about 60 miles east of Pensacola! My goal at the end of the road would be the Escambia County Emergency Operations Center.   CLICK FOR MAP AND PHOTOS.

My emergency radio gear (including spares!) had been packed for weeks. I added my portable generator, nine five-gallon containers of gasoline, my new Stihl chainsaw, plus two ice chests full of frozen two-liter coke bottles of water and non-perishable foods. I didn’t want to get assigned to a barrier island outpost without the essentials!

After receiving official blessing from my bosses (the Wife and my JEA supervisor), I headed for Pensacola early Tuesday morning, one week after Ivan went through Pensacola. By 4:00 PM, I had reached the end of the line for mere mortals traveling I-10: a series of concrete barriers guarded by National Guardsmen with M-16 rifles. All of the “normal” westbound traffic was being re-routed north and waaaay around the bay, but I displayed my ARRL Tracker form and told them that I was headed for the Santa Rosa County EOC in Milton, Florida.

With no hesitation, I was pointed around the barriers and back onto I-10. I drove for a while and exited at the last possible road before the ill-fated I-10 bridge. After a few more miles of driving wide-eyed through the “damaged area”, I arrived at the Milton, Florida EOC where I was greeted by Bill Hayden, the acting ARRL Section Manager. Bill thanked me profusely for coming and provided me a briefing on the local conditions. This advisory was being administered to all hams being sent further into the damaged area. The most important things to remember were 1.) Obvious hurricane-related hazards (downed wires, trees, broken glass and metal) and 2.) All intersections without functioning traffic signals were to be treated as a four-way stop. Simple enough, I thought. Back to the truck, and away I went.

After a 5-mile, 45-minute drive in stop-and-go traffic, I made it to the point where I was supposed to follow the circuitous route around the bay. Fortunately, one side of the double-span US90 bridge had recently been restored and two-way traffic was sharing the two lane span. I crept across the bridge and had a lot of time to survey the damage on both sides. The first thing one noticed was the really big boats that were scattered around the marshland like LEGO pieces in my kids’ room. I mean BIG boats……the ones that cost more money than I’ll make in an entire lifetime. The second thing was that I could see Plant Crist, one of Gulf Power’s largest electric generating stations. As a power plant engineer myself, I mentally wished them well in restoring their equipment. As I passed back onto dry land, I could see what shut the bridge traffic off on the other span….all of the approach road to the bridge had been washed away by the flow of the storm surge. The bridge itself, being installed on concrete piers driven down to bedrock, was still intact.

I finally made it across the “bay” (marshland actually) and was again on the four-lane road that lead into Pensacola. I had a difficult time finding my way across town to the EOC even though I had a good map - there were lots of street signs missing! In addition, there were few traffic signals working, in fact, many intersections were missing their signals altogether. Only the really major intersections had been restored completely and were powered by a generator (chained to the nearest light pole!)

I finally blundered my way into the Escambia County EOC parking lot and heaved a sigh of relief. I went inside and was ushered into the local ARES den…..a reasonable sized room with some interesting vintage HF gear that caught my eye. I didn’t stay long - the folks in charge said that they needed a couple of more hams at the Pensacola Corps Headquarters of the Salvation Army. As an added bonus, they had an emergency generator hooked up there that was “having some problems.” I was delighted to have a double challenge - electric power and communications! Hey, what challenge could a little electric generator be to a mechanical engineer?

After receiving directions to the Salvation Army headquarters, I headed out. Pensacola seven days after Hurricane Ivan can simply be described as a recipe of disaster. To put things into a Jacksonville perspective:

Take one large city - like Jacksonville. Have terrorists dynamite the Buckman, Fuller Warren, and Hart bridges into the St. Johns River. Remove 80% of all drinking water, wastewater, and electric utility services. Shut off most of the cell phones and landline telephones. Knock down several TV and broadcast radio antenna towers to add flavor. Randomly destroy most of the traffic signals and street signs, and shut all of the retail stores which sell essentials like food, fuel, and critical repair items. Add stress, hot weather and short tempers to help bring the pot to a gentle boil.

After another bout of low-tech, no-street-sign navigation through a heavily damaged, very-low-income neighborhood, I stumbled into the Salvation Army headquarters - a facility the size of an elementary school or a medium-sized church. I literally had to squeeze between tractor trailers being unloaded and dodge a forklift unloading pallets of foodstuffs. Just as the sun was setting I saw a van bristling with radio antennas so I bumped my truck over the curb to join in the excitement. I jumped out and was immediately greeted by Bill Brogan (KA1PA) of New Smyrna Beach. Bill already had HF and VHF stations on the air, obviously had communications under control, and so I went inside to introduce myself to the Salvation Army personnel in charge.

I was greeted by Captain Chris Nichols. (I quickly found that everyone in the S.A. has a military title!) He was ecstatic to find that I was interested in making his electric generator work properly. Seems like the FEMA-provided portable generator had worked for about one day then the facility AC system quit and the lights seemed about to fail, too. He set me up with a Major who almost dragged me out to the generator location…..and the “little” generator was revealed to me…. a screaming six-cylinder Cummins diesel engine driving half-a-megawatt of 480 volt, three phase generator, all built into a tractor trailer van! OK, forget the image of a Home Depot emergency generator! This generator was connected to the building with 12 flexible 4-ought copper welding cables as big as my thumb. In the headlights of my truck I walked down the system….and found one of the 480 volt cables lying on the ground by the service entrance breaker panel. NOT a good beginning! I didn’t want to shut the system down and darken the (still at work) facility at night so suggested that we wait until daylight to work on the system.

So Tuesday night I bunked down in one of the “classrooms” with six other SA volunteers. It was hot as blazes and muggy-still-close inside the building. There was still just enough electricity from the illing generator to ensure that fluorescent lights and receptacle power were working. I carried in and installed my bedroll and CPAP respirator. (I have a really bad dose of Sleep Apnea and must have my respirator anytime I want to sleep). The obviously exhausted volunteers looked at me, my bedroll, my respirator and my extension cord….one of them grinned and said - do you carry a fan too?? I grinned back and said “Sure, it’s in my truck!” He was really surprised when I made another trip to the truck and returned with a box fan. I was then warmly welcomed to join the group and we all hit the sack for some sleep. Just a breath of moving air quickly makes friends in the world of no air conditioning!

Sleep? So I thought. I had just gotten to sleep when I was awoken by the dead silence and no breathing air. Had the generator quit? It was REALLY hot and muggy in the building with about 125 snoring people spread around and no fans running in the halls. I grabbed my flashlight and crept out to the generator site…..sure enough it had quit. After a quick look-see, I mashed the starter button and the generator roared to life and the entire place lit back up. The all-important “electric breeze” returned. Back to bed I stumbled. I had just gotten back to sleep when I was rudely awakened again. I counted seven trips to the generator that night. I figured that a good night sleep with cool air for the SA volunteers was more important than my sleep.

The sound of tractor trailers, forklifts and voices woke me. The SA starts early….way before 06:00 they were unloading pallets of foodstuffs - sweet potatoes, turkey roasts, canned veggies, ice, and an endless vista of pallets of canned water. Anheiser Busch supplies SA with drinking water canned in aluminum cans marked “Drinking Water - Not for Re-sale “ and “Anheiser Busch”. I didn’t even mind the blatant advertising plug after I considered essential service they were providing to the tens of thousands of people without a safe drinking water supply.

After cracking open my first Diet Mountain Dew of the day and grabbing a cold leftover breakfast hotdog, I immediately headed to the generator. I took my Fluke multimeter and saw that there was a voltage problem with the generator output. I should have seen 480-480-480 volts measuring phase-to-phase. I saw 350-350-480. No wonder the AC chillers had quit! In addition to the uneven phase voltages, the voltages were not consistent - they swung up and down constantly, explaining the flicker of the lights and pulsation of the fans inside. There was something really wrong inside that generator!

I went back to my truck and got out an official ARRL message form (my legal pad!) and wrote a concise message for Bill to call into the Escambia EOC. I explained that we had no refrigeration in an emergency food processing facility, a serious fire safety hazard, and a deteriorating personnel situation due to the lack of full power (ie, AC) at the SA Headquarters. Most of the 100+ SA volunteers are retirees; many had been working every day since Bonnie came ashore nearly five weeks earlier! Bill transmitted our message, got a “solid copy” reply, and so we sat back to review the situation….what could we do to help now?

Bill and I spent much of the day re-starting the generator whenever it would quit. It would begin revving up in speed, then dropping in speed, and the changing speed and voltage caused large current swings on the generator, and the generator field winding breaker would trip, and “boom boom, out go the lights!” After watching this happen many times, I decided that the engine itself was starving for fuel (in addition to the generator’s voltage illness) and decided to try to find fuel filters for the engine.

While I was musing over this, one of the SA members had the misfortune of having a forklift lower a pallet (loaded with foodstuff) onto his hand. Between the bleeding from the laceration, the heat, (and I’m sure the pain), the fellow went into shock. Bill radioed the Escambia EOC and a few minutes later an ambulance arrived on the scene and took him to the hospital. What a sobering thought - nine days after the hurricane, there was still very spotty landline phone coverage, very limited Nextel/cell phone coverage…. and ham radio was the fastest way to get help. Imagine that…….!

Mid-afternoon I tired of sitting waiting around for the generator to quit. I rooted around in a hot, deserted office until I found a phone book. “A large NAPA store will have fuel filters for a Cummings Diesel” I thought. I wrote down the address of the Pensacola NAPA store, informed Bill and the EOC of my plan, and headed out on a mission. (ALWAYS let your EOC contacts know where you are!)

After two hours of circular driving (no street signs!), help from four different people giving instructions, and the grace of God, I found the NAPA dealer just before they closed for the day. They had Cummings fuel filters, and I got a case of motor oil just for good luck. In route, I saw two collapsed AM (?) radio station towers and numerous similar high-winds catastrophes. I also saw the other end of the Salvation Army relief operation - a parking lot where water and ice were being distributed to those in need.

When I got back, there was no power (again) and it was getting dark. There were more trucks to unload, and there was no light in the gymnasium-being-used-as-a warehouse. Bill and I had a quick dinner, (it was chicken and dumplings, not quite as good as my wife’s hand-made dumplings, but they sure tasted good to us!) We then headed out to the generator and worked with flashlights and my truck headlights to change the fuel filters on the generator engine. When we re-started the big diesel, it ran fine (no surging and dying out) but the generator itself had continued to decline in health throughout the day. The voltage at the electric receptacles had dropped to just 70 Volts AC……it would hardly run the fluorescent lights and the pedestal fans in the hallways and rooms.

Wednesday night I slept in the front seat of my truck…..not the optimal solution for a 46-year-old with back problems. The low voltage situation kept the fans from moving much air indoors, and I knew I couldn’t deal with sleeping inside with no air movement to help keep me cool. I had a 12 volt gel-cell wired up to my respirator to allow me to sleep…..a recent lesson learned during Hurricane Ivan’s minor visit to Jacksonville.

First thing Thursday morning, Bill and I realized that the Army needed some reliable power. We ginned up another message to EOC aimed at FEMA declaring a state of electrical emergency at the SA headquarters building.

After we received confirmation from EOC for our latest request, Bill and I unloaded my 4kW generator and pooled our extension cord assets. We hooked up all of the ventilation fans in the building and let the “big” generator handle just the fluorescent lights. Between the two of us we had a weeks worth of fuel to run the little generator.

With several big pedestal fans running at full power, the facility became livable again - we had mild temperatures and moving air made it almost livable.

Around lunch time, Captain Nichols approached me and asked if could help a nearby citizen.

Apparently the local United Way had called with a plea for someone to assist a nearby handicapped shut-in that could not get out of her house. A fairly large tree had fallen across her handicap access ramp and this woman had been barred indoors for about a week.

Captain Nichols took me to the house in an “inner city” neighborhood. On the way I was amazed at the amount of damage there was - tons of mutilated trees and structural damage to homes. Upon arrival I introduced myself to a lady in a wheelchair. She had both legs amputated just below the hip but was amazingly mobile in her wheelchair. She was extremely thankful for the offer to help and I spent several hours sawing up the tree into firewood lengths. While I was working, numerous neighbors came by to chat. Many of them spoke of volunteers from other places that had helped them or their families. When I was done, this lady thanked me profusely and told me that I must have been sent by God. (I’m sure Captain Nichols of the Salvation Army would have taken that as a compliment!)

I left the lady sitting in her wheelchair in her newly cleared driveway. For several days my thoughts kept returning to the blurb from an ARRL/ARES website stating that hams were supposed to restrict their activities to communications. I hope that Sir Hiram Percy Maxim will forgive me for my indiscretion. (Just kidding, sir!)

When I got back to the SA Headquarters, another miracle had occurred. FEMA had delivered a new (literally) generator to the site. WOW! Shiny new paint and a full tank of fuel! The electricians that delivered the generator had it hooked up and ready to run. We started it up (the diesel roar was music to my ears! - OK, I’m a geek!). We checked the voltage…..uh, 208 volts, shouldn’t it be 480 Volts!? Several cell phone calls later (yep, cell service was coming back after 10 days!) a factory rep was on the way to help us get all the bugs worked out. By dark we had 480 volts feeding the SA facility and lights were on. Bill and I worked together for quite a while to get the myriad of power panels reset. Bill found the operating manual for the chiller tucked into the control panel and soon had the chiller system re-started.

By the time the evening SA meeting was over, there was cool air flowing from the air vents in the meeting room. The people were ecstatic to have power and cool air restored. One crying lady came over and hugged me and told me she was so grateful to have a cool, lighted place to work. You just can’t believe the stress of working in such adverse conditions for days and days until you try it.

The only thing that Bill and I never got working was the water heater for the gymnasium…..we all took cold showers that night. I’m still trying to figure that one out. So after (another) cold shower and a few QSOs on the truck radio, I hit the sack.

By the time we woke on Friday morning, the word was out that the entire SA contingent needed to pack up ASAP and head to the Tallahassee EOC to await orders to deploy to whatever area needed help after the next hurricane…….Frances. Bill and I packed up our gear. I wrote up a detailed description of everything I could think of to help get the Salvation Army facility electrical service repaired and back on the electric grid. (Rental on the new generator was about $4,000/day!)

Captain Nichols and his fellow SA employees were profusely thankful for the ham radio and other support we had provided. By noon time Bill and I were back on the road. We had an 8-hour-long QSO using 2 meter simplex on the way home……is there a Guinness World Record for longest single radio conversation?....and we talked about radio and every other subject pretty much continuously for as we drove the long boring I-10 journey back across the state.

Postscripts

As a relative newcomer to the world of ham radio and volunteer emergency work in general, I have a few observations to make:

1.) Society as we know it comes to a grinding halt when the electricity, water, sewer, and retail sales (gas, food, supplies) supply systems stop. You can move back in time about a hundred years in a day or so when these essential services disappear.

2.) Restoration of these critical systems is extremely slow and inefficient without reliable communication. A week after Ivan, a backup emergency radio system was still needed in many parts of the Pensacola area.

3.) Never, ever count on cell phones for communications in any kind of emergency! For many reasons, cell phone systems can only be counted on to be conspicuously absent after a big storm. (What we suffered here in Jacksonville was just a windstorm!)

4.) There is whole a lot more to the Salvation Army than just the used-clothes store and Christmas-time bell-ringers. I was amazed at the extent and the organization of the SA emergency operation team. I saw loads of professional, dedicated, and truly compassionate people working - on the volunteer staff and the full-time SA staff.

5.) Despite the recent pooh-poohing of the need for (emergency) amateur radio services by some (amateur radio) individuals in (amateur-radio-related) online forums, I have witnessed first-hand what doesn’t work and what does work for communicating after a major storm or other emergency. After serving in Pensacola, I heartily recommend that all Florida amateur radio operators become active in their local ARES, RACES, Salvation Army, Red Cross, ham radio club, and other public service entities. Don’t let the negative nay-sayers turn you off to the utility (and fun!) of amateur radio!

5.) Everywhere we went in the Pensacola area there were signs proclaiming sincere thanks to the volunteers that came from other places to help.

6.) Camaraderie in ham radio still exists. Bill (KA1PA) and I met under adverse conditions, worked together, learned a bunch together, and had a great time working together, and will continue to QSO and meet in the future to expand our mutual interests in the hobby.

7.) Ed, after what I’ve seen, you can count on me for my support in future ARES exercises and activity!
