WARRIOR REVIEW: Versa Duo Portable Radio

DURING MY EPIC THRUHIKE of the whole length of Cebu Island, from southern tip to northern tip, in 27 days between January and February 2017, I gave premium for radio communications, simply because I am a licensed amateur radio communicator and I also wanted to test the repeater equipment of Ham Radio Cebu at distances and remote locations that were not done before with any amateur club in Cebu on their own by their members. It was an expedition within an expedition.

I am advocating for people to rediscover the joys of amateur radio because radios function long after cellular phone signals flounder during and after calamities and disasters. And also because I am an advocate of bushcraft and survival which I taught to a lot of people anywhere in the country. Portable radios are always part of the equipment when I am doing dirt-time with my outdoors club – the Camp Red Bushcraft and Survival Guild, or when I am doing seminars.

Now back to the Thruhike, I was fortunate enough that TECH1 Corporation loaned me two units Versa Duo VHF/UHF portable radios, together with extra batteries and desk chargers. Me and Jonathaniel Apurado carried a set each as part of our load. We both attached or clipped the radio to one of our shoulder straps. Sometimes, I just place it among bread and Yakult bottles inside a plastic bag I carried with a hand as I walked.

The casing and battery are black with orange highlights on the volume control, the flashlight, squelch button, VFO/MR button and the functions printed on the keypads. The antenna is about 11 inches long. It is longer than my Yaesu and Cignus units. Yes, it is made in China and it looked like a Baofeng UV5R but, unlike the Baofeng, Versa radios are approved for use in the Philippines by the National Telecommunications Commission and come with proprietary programming software.

When I received the radios, TECH1 Corp. had their showroom located then at Tipolo, Mandaue City. Currently, their showroom is located at SM Seaside City, in the South Road Properties, Cebu City. All Versa radios sold by TECH1 Corp. are under warranty. Besides that, TECH1 Corp. accepts repair of defective Versa radios and would program and load frequency channels for you on request. It is a very flexible radio that can be used in ham communications, civic activities and business operations.

The radios were exposed to the elements at any time of the day or night everyday for 27 days, along the routes and in our campsites. It functioned well even under prolonged exposures to the sun and heat, dust, moisture, rain, cold wind and, of course, rough handling. The total length of our walk was 400 kilometers at least, from sea level up to 972 meters, over an irregular and jagged landscape of ridgelines, rivers and valleys, steep hillsides, limestone forests and remote hamlets.

Operating the Versa Duo for propagation tests were done at 06:30, 12:30 and 18:30 everyday for 5 to 10 minutes duration. The Versa Duo allows for manual storage of frequency channels of different civic radio and FM stations and it could also be done with a software program, provided you have a Versa programming cable. The rest of the time, I turn off the Versa Duo to save power, unless I catch an FM signal at night and listen to music.

At the most, it took five days for the batteries to drain and charging power was never a problem since we sometimes stayed in villages. Power output for the Versa Duo is 5 watts and you would be amazed that at such strength, it propagated successfully to the repeater site of Ham Radio Cebu, located at Busay, Cebu City from Mount Bandera, Cansaloay, Oslob on Day 3 of the Thruhike. That is a distance of over 100 kilometers on line-of-sight principle!

The weather that time was stormy and we were enveloped by thick fogs yet it functioned well enough to maintain an exchange of readable conversation with another amateur station far away. It was amazing. At another time, on Day 15, I propagated from Kaluwangan, Asturias over mountainous obstacles about 20 kilometers away, but I pointed the antenna to the coastline, and I surprisingly received a reply. Another time, during Day 16, from Mount Mago, on the tri-boundary of Danao City, Tuburan and Carmen which is around 28 kilometers away.

My last successful propagation test was from the upper rim of the Doce Cuartos Mountain Range, in Mabuli, Tabogon, during Day 22, about 68 kilometers away. Beyond this line, it would be impossible anymore to do tests and I let the Versa Duo catch FM stations instead. On the last day of the Thruhike – Day 27 – I caught a transmission signal coming from Ham Radio Cebu at Bulalaque Point, Maya, Daanbantayan. The distance was just too great, about 120 kilometers. The Versa Duo propagates at just 5 watts. If it had 10 watts, I could possibly connect.

It was the first time that a Versa 2-way Radio was subjected to severe tests in a very unwelcoming environment like my Thruhike of Cebu. The rough handling was bad enough but it went well, nevertheless, through the whole nine yards of exposure to the elements – extremely - like every other gear that I brought and worn. I would most likely purchase a Versa Duo in the future or another model because it is a great radio equipment and it has a legitimate distributor in TECH1 Corp., where I am assured of technical support.

TECH1 Corp. also sells other Versa 2-way Radio models like the Alerto, the Command Tri-Band, the Quicktalk and the Quicktalk Pro, as well as speaker microphones and earpieces for Versa and other names. Aside that, TECH1 Corp. distributes the Versa brand of surveillance equipment and car security and products carrying the name of Ocam and Amaryllo. You may visit their showroom at SM Seaside City, SRP, Cebu City or contact them at (+632) 414-5177.

THE THRUHIKE JOURNAL: Days 2 and 3 (Monteverde to Cerdeña)

DAY TWO ::::: THE STRONG WINDS HAVE MELLOWED down while the monotonous tap-tap of the rain on my canopy have lulled me to laziness. It should be a cold morning but I am surprisingly warm. The Therm-a-Rest insulated foam pad which was provided by Michael Schwarz for the Thruhike have given me strange comfort which I have had not experienced before.  Indeed, I had a good night’s sleep free of worries but I have to rise from the comfortable capsule of my hammock.
 
I was amazed at our coverage of Day One.  We were not supposed to be camping here at Monteverde, Samboan yesterday but somewhere down short of here.  The first day adrenaline spurt might have to do with that.  Or that I intend to change the itinerary.  It is the latter but adrenaline and, perhaps, capsules of multivitamins and Guarana may have helped.  Here, we have a good water source and a perfect ground to set up hammocks and shelters.

It is 06:15 and I need to boil water for coffee.  Suddenly, my hands are afire.  Ants, known locally as “hakot”, have invaded the nooks and crannies of my backpack where I stashed my rice and everywhere on the ground and then my feet got stung and it was all over me quick.  They were working all night while I had that hangtime.  They were also on my Park N Go bread.  I gyrated to a tuneless dance and dragged my bag far, slapped it hard and shook off the tiny army.

 
I did have that coffee while watching over my Trangia alcohol burner doing its work on rice.  Jonathaniel Apurado, my buddy of this Thruhike, is cooking Knorr soup on his alcohol burner.  You might wonder how much food we carried for this journey?  We carried food good for five days only, intending to replenish our supply at Mantalongon, Dalaguete on Day Five, which would be on January 21, 2017.  We each carried a half kilo of rice, repacked in five plastic tubes weighing 100 grams each, and three packs each of Knorr flavored soups and another three for Korean spicy noodles.  Actually, I carried more for insurance if ever Murphy’s Law imposes its will on the Thruhike.

The warm Knorr soup mixed with warm rice on a cold morning is wonderful.  My food plan are soup for breakfasts, baked goods and energy bars for lunch and spicy noodles for dinners.  When we get a chance to pass by markets, we will change our diets but, basing on my food plan, this would be rare and few.  By now, you would get the idea of our eating habits for a month.  You know, planning the Thruhike is not easy.  You will have to study your itinerary long and hard before making it final, careful enough not to overestimate nor underestimate the distances between places found in maps.  When you have the itinerary, planning your meals are next.

The good thing about my itinerary is I could change it if I wished it.  I can enjoy this privilege because I have explored these places in segments.  Days One, Two, Three and Four are part of Segment VIII which I had passed by last September 2016 but we did that starting from Upper Beceril, Boljoon going down to Liloan, Santander and this Thruhike is going on a reverse, which is kind of tricky on your planned pace because it is uphill.  But Day One was spectacular because I changed it.

We leave the campsite at 08:15 just in time when curious locals visited us.  The wind began to pick up its strength and rain lashed at us but we still retained good manners to accommodate their questions and it turned out well and good.  One of those who came is Dominador Rodriguez, and we met him last time when we passed by here.  We followed him as we continue on our journey today, January 18.  Before I reached the boundary of Oslob, I informed their police station about our presence and our activity.  I might not get that chance for I know cellular phone signals ahead are absent. 
  
I do not feel tired nor I feel muscle pains from the labors of a forced march yesterday.  The amount of time walking among mountains done every Sunday for eight years have done wonders for my body and I have adapted well.  If this is to be a gauge then the Thruhike is good as done!  I have trained myself well even before this epiphany happened in 2011 but the greatest transformation is my mindset.  I might be older but I am better than when I was an invincible adventurer of the ‘80s and the ‘90s.

The trail passed by a well but we have already secured water.  We reach a paved road.  This same road goes down to Tumalog waterfall and to the coasts of Oslob but the one we are following is the unfinished Trans-Axial Highway which goes uphill.  The scenery begins to change when you are on higher elevations.  Valleys, farms, verdant hills, rocky cliffs and solitary huts dot the countrysides.  A Brahminy kite flew from behind me to the right and I take it as a good omen.  I tried hard to capture it with my camera but another one caught my attention as it called me with its shrill whistle.

 
For the moment, there is no other way to walk here but I see some shortcuts where it would bypass the pavements and it goes through forest trails.  Actually, you would not know these until you see a long bend or a hairpin turn and then you decide to explore a path which puts you on places where you most wanted it to be.  It goes perfectly well on three of such places because I was certain it would.  We reach Cañang, Oslob at 10:15 and rest at its barangay hall to talk to a local.  Although the building gave us warmth and protection from the rain and cold, we need to continue our walk and so have to leave this friendly village. 

The same road goes into more scenic scenery of long deep valleys on either side, choked with trees and approached by a series of low hills, farms and verdant meadows, landscapes which you would not know existed in Cebu.  The same Brahminy kites that I saw a couple of hours ago appeared.  By now, the weather turned mild with bit of sunshine.  We came upon a waiting shed at 11:25, at a place called Mohon, already part of Can-ukban, Oslob and we stopped for noonbreak. 

Since we were on higher ground, I decide to test the Versa 2-Way VHF radio on selected frequencies for Cebu City, Alcoy, Dalaguete and Argao.  Both Jon and I possessed amateur radio station licenses, being members of Ham Radio Cebu.  Cloudy weather, distance and mountains forbid me to come in contact with these repeater stations.  The rest is a good thing for it made me appreciate this structure at closer range than the last time I passed by here.

Well rested, we leave Mohon at 13:00 in a cloud of light showers. The concrete road is in good condition as it weave its way among hills and pocket forests which, to my mind, contain an enormous number of avian species.  From a distance, you will see this same road climbing up through more elevations and it would probably deter you when you walk it in another time.  The wet weather brought by a Low Pressure Area might have helped us in overcoming this obstacle but you will feel the cold as you go higher.

We arrived too early at the place where we are supposed to spend our second night, at 14:10, but it is pointless to go on under this uncooperative weather to seek shelter on another place.  We will just have to take advantage of the friendship we made with a couple who owned a concrete house which is located just across the Vincent de Paul Hermitage.  It is convenient for us to honor the itinerary this time, just in time to see Miguel Aniñon grind ears of corn with a millstone, which I caught in video.

We spend the rest of the day unloading our things to dry it out, together with our bags.  The hammocks were dry and that is the most important thing.  We do not have to worry about the rain since we tied it on the concrete posts of an unfinished concrete structure where there is a roof, although without walls, and owned by the Aniñon Family.  The location of their house, together with the hermitage, are located on top of a peak and we are, nevertheless, exposed to the spray of raindrops and cold wind.  That night, strong gusts and heavy downpour brought by the storm pelted our camp. 

Distance Walked: 10.37 kilometers
Elevation Gained: 754 meters from a low of 538 meters

DAY THREE ::::: THE COLD CREPT INTO MY SIDES where the Therm-a-Rest had not clasped me as it gave way to weight of body inside a hammock which had become soggy from the intermittent spray of moisture.  It was like that for the rest of the night and, here, early in the morning of January 19, I begun to wiggle out of my discomfort zone.  Jon had already started cooking the rice and boiled water for coffee on our alcohol burners.  The skies were still in a dour mood and it was raining.  The things that we dried yesterday, remained moist.

Fr. Carlo Curacot of the Vincent de Paul Hermitage came to pay us a visit after breakfast and asked of how are we doing?  After a while, he sent us warm buttered pancakes and, finishing it, we set out on our journey to the north.  The ground was wet and slippery but we decide to go against common sense by taking a steep shortcut downhill to evade a long bend of concrete road. We realized it was difficult to stay erect following this trail, more like a suicide mission, but we survived this unscathed.

 
An unpaved road is nice but trails are better.  Only, the trails to our next destination are in short supply.  When there is a shortcut, we took it and, most often, it is so muddy and slippery.  We stop by a small house with so many family members at 09:50 on a boundary between Oslob and Ginatilan.  A matriarch, Damiana Cariño, 72 years old and bent to so much time working in the fields, talked about her predicament of never receiving cash allocated to senior citizens from both towns.  We advised her to focus on the town where she is registered as a voter.  That is where most local funding is based on, of small towns where politics are so divisive.

Another shortcut brought us to another stretch of unpaved road and a welcome sign says Manlum, Oslob and another says Cansaloay, Oslob.  Up ahead would be a shallow well fed by a natural spring.  It is a small marshy place and is one of the headwaters of the Laguinsan River which wind its way to the coasts of Oslob.  A trail goes up to a bald hill which goes up and up.  The rains had not abated, winds picked up strength as we gained elevation.  Fogs obliterate the landscape, making navigation a patchwork of guesses and tells.

Most of the time, I am caught off-balance by the force of the wind.  The Therm-a-Rest is slung across my shoulder to the front of my body and is the object of so much wind resistance so I have to clip it lee of the wind with my left arm.  Mt. Bandera would just be around there beyond my vision obscured by fogs.  As I go further, terrain which lay invisible begun to show its earthly appearance, blurry humps at first then in great details.

Now I am on the hump that is Mt. Bandera and we stop for a while to send out another propagation test to a repeater station of Ham Radio Cebu, found in the Babag Mountain Range of Cebu City, a distance of about 118-120 kilometers.  I am testing a Versa Duo VHF Radio, with stock antenna and 5 watts power.  The first stream of communications was received by station DY7EYN at 11:00 but was interrupted by bad weather and cut short.  The second one at 11:30 went out seamlessly and acknowledged by station 4F7MHZ.

Satisfied by the results of the worthiness of the Versa Duo in extreme weather conditions, we go down the trail towards Tigib Spring, another source of the Laguinsan River.  We arrive at 12:10 and enjoy our 50 minutes of noonbreak under the onslaught of streaming winds and whipping rain.  We munch on energy bar, biscuits, bread and mixed trail food.  I foraged ripe guavas and sliced it in halves with my Buck Classic 112 knife.

 
At exactly 13:00, we followed the trail that would join with an unpaved road, which would become one with a paved one, recently concreted.  This road goes on lazily uphill, twisting and bending forever towards the sky, passing by either at Malabuyoc or at Boljoon, again and again.  The good thing is the rain had abated for a while and there are no fogs to block your view ahead although the wind still ruled the higher elevations, especially at the most exposed areas.  At this stage, I informed both the Malabuyoc Police Station and the Boljoon Police Station of our presence in their area.

At a point where it is most elevated, the road begins to twist and bend downward.  Heavy rains have clogged up ditches with silt and pebbles, on some points, carrying whole culverts down the mountainside.  Landslides threaten a house below while cracks on elevated ground above roads is something you would not want to happen where people pass.  I have not seen one vehicle, not even the omnipresent motorcycles-for-hire.  But there is life here.  A boy rode the back of his carabao while a noisy party of intoxicated locals just came out from a house where there is a feast of some sort.

Schoolchildren walked their way home from school and some of them run at the sight of us.  Stories of child snatchers pervade everywhere and we fit the description of big bags to stuff children inside.  Cannot blame them for these places are indeed lonely which a newly-opened road could not change immediately.  In time, maybe they will get used to the sight of a backpacker.  I hope so.  The Thruhike opens you to different local cultures and different people who harbor different beliefs and, most of them, are talkative enough to tickle you with their simplicity.

By now, the road is eerily empty and silent.  I found a copse of mahogany trees which I have eyed before as a perfect camping site for hammocks.  It is now 15:30 and I do not know if we would get another opportunity to find a good place like this to camp up ahead.  This is perfect, although it is just ten meters away from the road.  It is slightly elevated, since we are at the shoulders of Mount Ablayan, and trees are growing near each other that could hide several shelters.  I got a light gray taffeta sheet and Jon has a brown laminated nylon sheet.  Both are of neutral colors and we are good in stealth camping.

Immediately, I tied the partly-moist hammock to separate trees to wick away moisture while I fixed over it my wet taffeta shelter.  Then I removed all the things inside the bag to let it all dry, carefully storing the food cache above the ground.  I fixed the drip lines at each end of the hammock in the event rain will come.  Set up my Trangia alcohol burner at a spot where I could comfortably sit, scratched the small ferro rod of an Advanced Pro Fire Starter over the alcohol fumes and a fire erupted.  So began my coffee moments.

I cooked the rice and then my first supply of spicy Korean noodles.  Jon seems satisfied with his shelter but there is something different in him today.  He looks fatigued.  Maybe the weight he carried.  His bag is bigger than mine.  We both expect an expedition type of activity but I carried things that are necessary even though some have redundancy in functions.  I even left my metal cup, preferring to savor coffee from the extra lid of my smallest pot.  The only extra luggage I have is a selfie stick.

But there is also something different with my feet today.  I felt a soreness at each base of my big toes.  Walking with wet unbroken shoes and new socks since Day One might have rubbed the skin of the big toes.  The pair of Jack Wolfskin fits just right but it would have been better if I broke it down for a few days before engaging on the Thruhike.  Same with the Lorpen cotton socks which were provided by Viajero Outdoor Centre at a special price.  We are still on the third day and I do not want some things putting a monkey wrench on the Thruhike.

 
In my mind’s blueprint, I would use the same socks and undershorts for four days and will change to new ones only on the fifth day and the eighth day afterward for this southern leg.  The Silangan Outdoor Equipment hiking pants and shirt would be worn without spares for the whole of the Thruhike.  I could only wash it, perhaps, in places where there is an abundant supply of water but that is just about it.  I cannot assure myself if I could take a bath nor brush my teeth.  I hanged my moist jersey, hike pants and wet socks for drying.

Despite our efforts to camp stealthily, I noticed schoolchildren running so fast on the road when they passed by near our campsite and then sneak a glance at our direction.  They have developed keen eyesight even at hours where everything stood gray and they could distinguish something that is not right.  I may fool a mainstream hiker but I cannot fool a mountain youth.  I toast my coffee lid, for want of a cup, to them.  There is light rain yet we enjoyed supper at 18:00, while there is still light.  Rain and wind lashed back its fury during the middle of the night but I am warm even half naked.

Distance Walked: 11.94 kilometers
