2014/06/03 — Tuesday — Lunch at Jamaican Grill

After the wiring changes yesterday, I was able to complete the move of a power supply for a LED strobe light that is turned on outside the building anytime a transmitter is on the air.  This is used as a warning any time high voltages are present on the feedlines and antennas.

At noon the staff, including wives and children, was invited by Daryl and Gaynelle Renshaw to lunch at the Jamaican Grill — http://www.jamaicangrill.com — at the north end of Guam where the major stores are located.  Daryl and Gaynelle are home-based in Singapore where Daryl serves as the Asia Regional Support Services Leader and Gaynelle serves as the Member Care Coordinator for TWR’s missionaries in Asia.  They are visiting with the TWR Guam staff for a few days.  It took about 30 minutes to get from the transmitting site to our apartment, where I freshened up and picked up Virginia, then another 30 minutes to get to the Jamaican Grill.  There we had a great time of fellowship with the Renshaws and all the staff.120603 -- JamaicanGrill

After lunch, we returned to the site and I attempted to repair one of the spare analog-to-digital metering boards for the Thompson 250,000-watt shortwave transmitters.  I was told that the 5v to +/-15 v converter was bad, so I installed a substitute converter, since the part originally used is obsolete.  Unfortunately, it did not correct the problem and because the day shift was ending, this became a project to tackle tomorrow.

2014/06/02 — Monday — 2nd Day at Transmitter Site

Today, Virginia moved our things into ‘our apartment’ which is located in Agat, Guam on Route 2 about 200 feet south of its intersection with Route 12.  We are across the road from the ocean, but because our apartment is on the second floor, we have a good view of the ocean.  The sunsets should be amazing! If this link — http://goo.gl/maps/LRofz — works right, our white roofed apartment will be under the point of the green arrow.

Virginia is standing by our apartment on the far right of the top level.  The other two apartments are vacant at the moment.  The typhoon shutters are closed on our bedroom in an attempt to keep it cooler.  The Toyota Highlander that we are using is the vehicle on the far right.

For reference, TWR’s transmitting site is at — http://goo.gl/maps/4vSra

At 7am I left for the transmitting site with Paul and started work at 7:30am.  Devotions are at 8:00am and usually last 15 to 30 minutes, but today the Director of Asia Region for TWR was here and spent a couple hours talking about new developments within TWR.

After the meeting, I helped Mike Sabin, the chief engineer, tune up the HC100 on an out-of-band frequency that he had been unsuccessful in tuning.  This frequency will be tested later this week for use in broadcasting in cases of emergencies, such as major typhoons, earthquakes, tsunamis, volcanoes, etc.  This is being done in cooperation with a large network of stations in many countries.

This afternoon, Mike gave me an inside tour of the Thomson 250,000-watt shortwave transmitters.

Later, I began to do some rewiring to facilitate a major move of the old Harris transmitters that should be taking place next week.

It was nice to come home to our own place this evening, and supper prepared by Virginia!

2014/06/01 — Sunday — Harvest Baptist Church

We attended Harvest Baptist Church — www.hbcguam.net — this morning, which is about a 30 minute drive from where we are staying in Santa Rita.  It is to the north and located on the south side of the airport.  We did not find the former supporter today.  One of the members stated that he has been experiencing “health issues,” but that he is usually there.  Maybe we will try again next Sunday, but doubt that we will drive that far every Sunday as there are so many other good churches much closer.

First time visitors at the church are given welcome bags.  Each of us, got a nice insulated drinking cup with lid and straw.  There was also a Hershey bar in each bag, but with the heat they were in a liquid state.  A few minutes in the freezer when we got home restored them to being edible, versus drinkable!

On the way home, we stopped by a couple of the many war memorial parks that are on Guam.  Our last stop was at the T. Snell Newman Visitor Center — http://www.nps.gov/wapa/t-stell-newman-visitor-center.htm —  just outside the navy base, which gives a great timeline of the history of Guam and especially the events from 8 December 1941 (when Guam was invaded by the Japanese only a few hours after the attack on Pearl Harbor) to 21 July 1944 (Liberation Day in Guam when American forces began to retake Guam) to 10 August 1944 when Japanese resistance ended.

We only saw a few of the displays before closing time, so will go back later to see more.  This really shed some light on the significance of the various other war memorials we have already seen and many others we hope to visit while here,

2014/05/31 — Saturday — Lunch at Sabins

Today was a rather lazy day trying to recoup from the first full day of work yesterday,

This morning was spent adding photos to and updating our previous blog entries.  As usual, our computer did not want cooperate and, at one point, it was necessary to uninstall our photo editing program and reinstall it before it was possible to get it working again,

At noon we were invited to Mike and Eli Sabin’s home for lunch.  Eli had made a taco casserole with large pasta shells.  It was very good.  We had a wonderful time of fellowship for almost four hours.  The Sabin home is in the ‘mountains’ above Santa Rita in a somewhat rural setting,  Free range chickens lay eggs in the carport.  Wild pigs and monitor lizards are common visitors.  Two streams met in their back yard where a large forest of bamboo plants about 60 feet tall are located,

We had a light supper of salad with the Gregowskes this evening.  Also, are planning our trip to a church on the north end of Guam in the morning.  Hopefully, we will meet a friend there who supported us for many years.

2014/05/30 — Friday — 1st Day at Transmitter Site

Paul  decided that we should take the Highlander to work to get it repaired.  I verified that the problem was not the transmission, but the linkage.  With assistance from Paul on the brakes, it was possible to manually shift it into ‘drive’ from inside the engine compartment to allow us to drive it to the transmitting site.  Since it was not possible to downshift going down the hills, we drove slowly for the 15 mile trip and had no problems.

While I evaluated some transmitter ‘challenges’, Joel Harp took apart the gear lever linkage, discovered and repaired a plastic bushing that was cracked.  The repair was done in about an hour.

The HC100 has been tripping off very briefly several times during the past few evenings due to an optical arc detection.  I saw that the boiler feed pipe had a lot of ‘dirt’ particles in it.  Since there are peaks of 30,000 volts across this pipe, this could be the source of the problem.

Phil and I removed the pipe and cleaned it.  It was decided to flush the boiler for the tube as this is the primary source of the ‘dirt’ particles.  Having done the flush and reconnecting the pipe, Phil began to refill the system with clean water.  Fortunately, I was watching closely and noticed ‘dirt’ particles being carried into the feed pipe from the opposite end of the pipe from the boiler.  As a result, we determined it best to remove the feed pipe again, clean it again, and flush the system from the other side.  Hopefully, this will take care of those pesky trip offs,

I was also asked to look at the HC100 tunable harmonic filter and discovered that the active turns of the two coils are not the same — they should be the same!  It will be necessary to obtain some more information from the technology center in Elkhart to make the proper alignments.

Tonight we had supper — meat, mashed potatoes, gravy and corn — with the Gregowske’s, where we are temporarily staying.  We had been invited to see a movie at church, but decided to pass,  I was too tired and we had already seen this particular movie.
