2014/07/14 — Monday — Servo Amp Repair

Not much happened on the antenna switch installation, because Jim worked shifts over the weekend and today was his day off.

I did troubleshooting of two servo amplifiers for the Thompson transmitters.  There are two spares and neither of them work.  Each amplifier has two different boards.  We discovered that only one board was bad on each amplifier.  Fortunately, the bad board on each amplifier was not the same type on both.  It was possible to make one good amplifier out of the two.140714 -- ServoAmpsOur evening was spent working on our August 2014 McGuiReport, which is due for proofreading on 15 July.

 

2014/07/13 — Sunday — Ritidian

There was a great septet of lady Chamorro singers at Harvest Baptist Church.  Pastor Herron continued his series of messages from Genesis on the life of Joseph.  This series will come to an end on the last Sunday we are here.  How’s that for timing?!

140713 -- SeptetAfter church we headed north to Ritidian Point. This is the place we arrived at last week too late to enter.  We wanted to get there as quickly as possible.  Here is a photo tour of our afternoon:

First a quick stop at Home Depot to get a replacement light switch for one of our ceiling fans, then a quick stop at Kmart for some bread and milk.  At Kmart we saw at least four buses bring Japanese tourists from the hotels.

To get a quick lunch, we stopped at this McDonalds, with a retro look, on the way.  Actually it is on Navy property, but open to the public.  The fence of Navy property goes around the perimeter on three side.  There were two large refrigerated semi trailers parked behind the store to provide extra cold room capacity.

The road to Ritidian became quite full of potholes after the last main gate into Anderson Air Force Base.

The island of Rota is about 40 miles away.  Although smaller than Guam, Rota's mountains are higher.  As of July 2013, there were just 131 registered automobiles on the island of Rota -- http://en.wikipedia.org/wiki/Rota_(island) -- compared to tens of thousands on Guam!

Our first trail originated at the nature center.  We're off to find Casa Real the site of an old church.

Our first trail originated at the nature center and headed toward the beach. We’re off to find “Casa Real (Site of Old Spanish Church).”

We looked all over for Casa Real, but found no signs or anything else, except maybe this 'clearing'.  Doing research at home we found that although there are photographs of ruins taken in 1952, that the area was bulldozed in the 1960 for a Navy Sound Surveillance System (SOSUS).

We looked all over for Casa Real, but found no signs or anything else, except maybe this ‘clearing’. Doing research later, we found that although there are photographs of ruins taken in 1952, that the area was bulldozed in the 1960s for a Navy Sound Surveillance System (SOSUS), which was decommissioned  in 1992 after the Cold War. This information should be on the provided maps, or at least on a sign.  We wonder how many other people have searched and found nothing!

Walking through the ‘jungle’ towards the beach, we did find hundreds, maybe thousands, of butterflies — they were everywhere! It was hard to get a photo of them, but a few can be seen on the branches.

Each butterfly would land, folds its wings and then open them once, or twice, before keeping them folded.  It was a challenge to try to catch on with its wings open, especially with the time delayed shutter of our small camera.

It was a challenge to try to catch one with its wings open and get it in focus, especially with the time delayed shutter of our small camera.  Here’s the best we could do.  These are Blue Banded King Crow Butterflies.

After passing through the 'butterfly forest', we reached beautiful Ritidian Beach.  This is looking to the left (west).

When we got to Ritidian Beach Cave the trail was closed.  the entrance is just tall enough to walk into without bending down.  Apparently the caves and trail are closed for archeological reasons, so we did not go inside and returned to the nature center.

By this time, we needed to head for home.  Mike had requested that Larry go to the transmitter site with him at 5pm to help repair one of the Thompson transmitter that was having servo problems.  As it turned out, a connector was bad on another servo.  The spare servo motor was installed, and Larry repaired the connector on the servo motor that had been removed.  Another site that uses these Thompson transmitters has replaced all of these connectors with better ones.  That will probably be a good idea here, too — for all 26 servos or 52 connectors!

2014/07/12 — Saturday — South To Merizo

We woke up to find that it was raining fairly hard, but the wind was very light compared to the 60 mph winds that had been forecast.  We learned that the storm warning had been lifted.  Tropical storm Rammasun had swerved to the north, circumvented Guam, and continued on its anticipated course toward the Philippines. We know many were praying — could it be??!!

There was lots of standing water and it was still raining when we looked outside this morning.

There was lots of standing water and it was still raining when we looked outside this morning.  If it keeps raining like this in days ahead, there will be a jungle in our ‘front yard’.

About noon, the rain let up and we decided to head south again and took these photos:

As we started south, we noticed that there was a very low tide.  It appears that it would be possible to walk to these two islands in Agat Bay, which are normally surrounded by water, without getting wet feet.

Mt Jumullong Manglo, to the south of Mt Lam Lam, has about a dozen crosses on the top. It is the second highest peak on Guam at 1,283 feet.  Hundreds of Guam Catholics make an annual pilgrimage on Good Friday to the top.

Our next stop was at Merizo — http://www.guampedia.com/merizo-malesso  — where we were rained out on our last trip south:

The Meryl G Cook School in Merizo was built before World War II.

This Merlyn G. Cook school in Merizo was originally built in early 1941 by the US Navy for radio communications just before the Japanese invasion.

We headed back north toward ‘home’ in Agat, but decided to stop at the village of Umatac to see if we could be more successful in locating Fort Santo Angel than last time.  This time, we determined to try access from along the shore.  Virginia was not wearing shoes to traverse the rocky shore and waited for me.  Starting from the sign for Fort Santo Angelo — http://www.guampedia.com/fort-santo-angel/ —  I walked along the rocky shore for about 100 yards and saw steps heading up the rock at the entrance to Umatac Bay.

Walking on the shore, it was easy to see the Fort Santo Angel on top of the rock. [Sorry this photo is out of focus and our camera's battery died before I could retake it.  Will try to replace this photo with a good one]

2014/07/11 — Friday — Prepare for Tropical Storm Rammasun

I helped Mike inventory the parts for the solar panel array that arrived Monday.  Photos of some of the parts are below:

Forty of these steel post are cemented into the ground to support the panels.  Each post supports six solar panels.

Forty of these steel post will be cemented about 6 feet into the ground to support the structure for attaching the solar panels. There will be 4 rows with 10 posts in each row.  Each post will support 6 solar panels.

Because of all the other projects underway here at TWR Guam, a local contractor will be doing the installation of the solar system. Hopefully, he can start on it soon.  We would like to see what it looks like before leaving here on 31 July.

Because of the extra cloudy day, the antenna curtains seemed to stand out more clearly than normal.  Here are a couple fairly clear photos:

All day, reports were coming in that tropical storm Rammasun was to hit tonight.  Local stations were warning everyone to prepare for this storm and the possibility of being without power and/or water for several days.  Many offices were closing early to allow their employees to prepare their homes for the storm.

After we prepared the site for the storm, by securing anything that might get blown around in 60 mph winds, Mike allowed us to go home a couple hours earlier than normal.

The first thing we did when I got home was to fill two of our 5-gallon water jugs. The Water Store had already closed for the coming storm, so we headed to another one we had seen about a 1/4 mile in the other direction from our apartment.  Fortunately, it was open.

Virginia filled a large waste basket, a bucket and another water jug with tap water in case we needed water for non-drinking purposes.

Next on the agenda was to close all the typhoon shutters all six windows.

The shutters are held closed by deadbolts at the top and bottom.

The shutters over the windows are closed — now to close the shutters over the door.

Lastly, we tried to close the shutter on the front down, but found a problem!  The screen door is between the shutter and the front door.  The shutter could only be closed from the outside!  That is not problem, if you are living on the ground floor, because you can close the shutter from the outside and get back in through the back door.  That is not an easy to do when our apartment is on the second floor.

We have a problem!  The screen door has to be open to close the shutter from the inside.  Not possible!

We have a problem! The screen door has to be open to close the shutter from the inside. Not possible!

After investigation, I discovered that the screen door is designed to lift off its hinges.  Another problem — the plaster around the door was done in such a way that the screen door could not be lifted high enough to get it off its hinges (maybe the hinge pins will need to be shortened for future storms). To still have this problem, this apartment complex was probably built after the last typhoon that occurred 12 years ago.

Since this is only a tropical storm and not a typhoon and we should not experience storm surge, especially on the second floor, we decided to leave the door shutters open.

The Lord provided a beautiful sunset this evening before the coming storm.

2014/07/10 — Thursday

Not a lot to report for today and, sorry, NO photos!

Here are a few things that were done:

1. Advised Mike about the various possible options of obtaining  a spare DVR2000E+ regulator for the standby engine from Ebay.  The Plus version has a digital readout which can be fine tuned more easily and it can be set up on the bench.  The DVR2000E has to be set up, and adjusted, in the extremely noisy environment of a running engine.

2.  Cleaned the rust off the drive spline of the servo that we removed and repaired yesterday.  The servo was then returned to the stockroom.

3.  Helped in the shop with preparing the piping for the first connection from an antenna switch to the overhead line installed earlier in the week.

Jim invited several of us to have dinner with him at Denny’s this evening.  Virginia and I rode with Joel and Joanna for the 13 mile trip to Tamuning and met Jim there.  Phil and April were the only other ones able to be there.  We had a fun evening together and came home stuffed.
