1998 TEXAS WATER SAFARI
"THE TOUGHEST RIVER RACE IN THE WORLD"
THE RADIO-ACTIVE POINT OF VIEW
by Paul Johnston -
KA5FYI
That's right partner! Two hundred sixty miles of non-stop paddling form San
Marcos, Texas to Seadrift, Texas. Start out at the beautiful Aquarena Springs
on Spring Lake (the headwaters of the San Marcos River) where glass bottom
boat tours are given. Now start paddling your arms off in the clear fresh
spring water and end up in the salt water of the Gulf of Mexico after you
have navigated across open water in Guadalupe and San Antonio Bay. The finish
line is the flagpole at Bayfront Park; Seadrift, Texas.
If you are the winner, you will have completed the non-stop race somewhere
in the area of 35-43 hours ( 1997 high water record was 29hrs:46 min.) when
there has been lots of rain to fill the rivers. If there has been little
rain, then you, the winner, will spend 47-58 hours ( 1984 low water record
was 54 hrs:00 min.) in your ordeal of fire. What if you are not the winner?
Holy Cow! You only get 100 hours to finish! The race starts at 9 A.M. on
a Saturday morning in early June and ends the following Wednesday at 1 P.M..
There are several classes of canoe teams that can enter. If you are real
macho, you are allowed to go solo. To see the 1998 Texas Water Safari Complete

Now that we have gotten past the starting line, what kind of physical dangers
will our bodies go through? Let's start with sleep deprivation, heat exhaustion,
dehydration, amnesia, followed by vivid hallucinations. Now comes the water
hazards: rapids, paddling over dams, struck by overhead branches and other
manmade structures, pinned against tree limbs, trunks, or rocks, and lastly
portaging your canoe through, over, and around log jams. Oh yes, one other
matter of concern, the perils of mother nature: wasp stings, fire ant bites,
snake bites, alligators, stepping on stingrays and finally sharks. Since
you will be wet much of the time, you may have to contend with diaper rash.
But despite all of the above, when you finish, you will have a new outlook
on life forever. Believe it or not this is really a fun event. This year
will be the 36th river race. It all started back in 1962 in a
bar when some people bet some local that they could take a motorless boat
from San Marcos, Texas to Corpus Christi, Texas. Thirty days later they succeeded
and thought that others might enjoy the challenge. So, in 1963, the first
race was held. Would you believe at that time the race was over 500 miles
long? That was when people were leather tough? Even today everything has
to be carried inside the boat. The only thing that can be given to the canoers
is water and ice.
Now for the fun part, amateur radio (ham) to the rescue! You can imagine
what a chore it is keeping up with 50-70 canoes and crews strung out over
260 miles of river. However, with 50 plus hams located at 13 check points,
the job gets done in an excellent manner. Our job is to provide a margin
of safety and to keep track of which boats have pulled out of the race so
people will not start trying to locate boats that are no longer participating.
There are race officials at various check points where the teams have to
sign a rooster. At these checkpoints, we make a note as to what time the
boat passed and what the boat number was. This information is then transmitted
downstream to the next point. If a boat quits, that information is also relayed.
In this manner, if any boat does not pass a certain point within a reasonable
time, the race officials will know exactly what section of the river a boat
is missing, thus saving valuable search time.
The farther from the starting point a check point is located,
the longer it has to be manned by amateur radio operators. The hams near
the finish have to be in place a little after a day has passed from the starting
time to the official finish time. Thanks to many willing volunteers, this
public service activity is a real joy to participate in. This will be my
17th year to serve. I look forward to this event every year; it
has now become a family event. A little over a year ago, my wife Barbara,
KC5ZSB, and my son, Sam, KC5ZSQ, became "radio-active". That is, they studied
and earned their amateur radio license from the Federal Communication Commission.
For the last two races they have collected boat numbers, times, and radioed
this information downstream from Cottonseed Rapids to Staples Dam. Each year
I meet new hams and lots of familiar faces. I am at the start of the races
at Aquarena at 9 AM Saturday morning. Then, we drive to Cottonseed Rapids
about 5 miles east of San Marcos and start recording the first boats coming
past this point starting around 10 AM.. What nice memories this event has
made for me.
Radio communications itself between checkpoints can be challenging. Almost
all of the communication points are located below a highway bridge. Over
past years, VHF/UHF repeaters that take radio signals from the checkpoints
and "retransmit" them downstream were sometimes not available for various
reasons. This made communications more difficult. Beam antennas would have
to be mounted on a short pole and carefully clamped to the bridge as to cause
no hazard to traffic. Drops of 100 feet of coax from antennae to radio are
not uncommon. If you are not located under a bridge, then you are down at
river level which can be some distance below the average elevation of the
terrain. Given these communication obstacles, experimentation with various
combinations of equipment, antennas, and location is a natural evolution
of the communication problem solving process.
Over the years I have tried many mad scientist radio brainstorms. Maybe these
brainstorms are really a manifestation of the "junk box" mentality or "What
can I use that I already have?". At Cottonseed Rapids where I work down at
river level, there is a large hill of about 300 feet from the main road to
the river. Over this distance there is a vertical drop of about 50 feet
elevation. From this point to the downstream communication point at Staples
Dam, the river has many bends and is heavily wooded. At Staples Dam, the
hams set up a beam antennae pointed toward Cottonseed Rapids. Unless we have
a push-up pole located at least 100 feet or more up the hill, we cannot
communicate. Even repeaters were hard to hit at river bottom. What that means
is that you will have to climb the hill in the hot summer temperatures many
times over a four hour period to communicate. Once up on top of the hill
at the main road, then only a watt or two on vhf mag mount 5/8 th wave antennae
works very well.
Pondering the above in 1988, I realized that what I needed to
accomplish communication was to
get my signal up the 300 foot hill and down the road. I began
to think of the various radio equipment that I had ; I did not have all the
right combinations of equipment. Enter the brainstorm. I remembered my now
late friend, WA5RON, Jerry Johnson had a pair of World War II vintage
walkie-talkies called the BC-611. This radio operates on 80 meters (3885
MHZ) AM and puts out 1/4 watt. Could this radio be used with a cross link
from my Yaesu FT-757GX HF rig that will operate AM to my Yaesu FT-209R all
mode 2M rig. With Jerry's help, the answer was "Yes!".
It worked well. Here is how the set-up looked. In my Suburban,
I had the FT-757GX connected to a Hustler 80M whip antennae. My 2M rig was
linked to the HF radio by a simple circuit designed by Jerry. The 2M rig
was connected to a 5/8 wave mag mount on the roof. Down by the river, we
used these John Wayne walkie-talkie on 80M AM to get up the hill and come
out on 2M FM heading for Staples Dam. The 2M signal coming from hams at Staples
Dam would go back down our hill on 80M AM.. Our only fear was that some local
SPAMMERS (Society for the Preservation of AM) might be on the frequency these
walkie-talkies were set up on. We had heard them there before. We were fortunate
and things worked out just fine.
In 1990 following the same train of thought of using what I
had, I fixed up cross links of 49 MHZ to 2M and a back-up cross link of 11M
to 2M. However, the 49 MHZ link did not work due to a large amount of electrical
interference at this location because of the high voltage lines nearby. So,
I connected up the 11M / 2M link in the Suburban and used a AM 11M talkie
to get up the hill. All this experimenting was very educational and gratifying
to know that I used what I had easily available to me.
By 1997, cross band dual band mobile rigs and handi-talkies
had become a common item. Last
year we used 440 MHZ of a dual band handi-talkie to get up
the hill to the mobile dual bander and out on 2M to the repeater. This year,
we had access to a repeater that was easily accessible by handi-talkie from
river bottom. This made it a real treat to operate by not having to lug lots
of radio equipment up and down the hill.
So, if you have a desire to walk, talk, and swim on the wild side, come on
down to San Marcos, Texas at the first part of June and either join up with
amateur radio operators or become a maritime mobile "River Rat" in "The World's
Toughest Boat Race".
