2014/07/24 — Thursday

Our morning started off with a Skype conference meeting with the Human Resources department at TWR Cary headquarters.  There were people from about 5 different locations involved in this meeting.  I continue to marvel at what can be done using today’s technology!

After the meeting, I continued to work on the adapter to connect the VIM probe to the balun.  This required some lathe work to make everything fit together.

All the parts for assembling the connector, except for one.  I had to turn a plastic spacers on the lathe to hold everything together.  The lathe was also used to make the ring in this photo and to shorten the other end of the connector to make the probe fit better into its 'socket'.

All the parts for assembling the connector, except for one — I still had to turn a plastic spacer on the lathe to hold the parts snugly together. The lathe was also used to make the ring in this photo and to shorten the other end of the connector to make sure the probe fit to the correct depth into its ‘socket’.

The spacer made on the lathe is being held in place here by the ring.  Notches were made on the inner diameter of the ring to allow it to be tightened (or removed) using circlip pliers.

After the reducing coupling for copper pipe is pressed onto the connector, the project is complete.  The probe can now be connected neatly to the balun without danger of bending the probe tip.

The Vector Impedance Meter and balun were now tested with a 300 ohm load.  The readings were correct from 3 to 20 MHz.  We can now be confident in the readings when the antenna switch matrix is measured to verify whether the impedance is correct.

The Vector Impedance Meter and balun were now tested using the 300 ohm load. The readings were correct from 1 to 24 MHz. We can now be confident in the readings when the antenna switch matrix is finally measured to verify whether its impedance is correct.

We learned that the two containers, with the old transmitters, are supposed to be loaded onto a ship on 30 July.  This means they should be picked up soon — preferably before this weekend’s anticipated rain.

 

2014/07/23 — Wednesday — Connector Fabrication

The proofread copy of our August McGuiReport was returned to us, so I took a few minutes before work to make the suggested corrections and update our travel plan information, now that our air tickets have been purchased.

My first task of the day at the transmitter site was to document what was done on the PA inductor yesterday, and outline what still needed to be done, then submit this information to Mike.  Hopefully, he can have the final improvements done to the coil, once the newer design of leaf springs arrive.

Mike wanted me to verify that TWR Guam’s vector impedance meter (VIM) was measuring correctly.  This needs to be done to insure that it is ready to use when it becomes time to verify that the antenna switch matrix impedance is acceptable before putting the matrix into service.

The probe of the meter has a very fragile tip, which is vulnerable to bending, or breaking.  These tips are obsolete and very expensive to replace, if one can even be found.  I was looking for a special connector that would protect the tip and connect directly to the N connector on the balun.  [Since the transmission lines are unbalanced and the meter has a balanced probe, it is necessary to use a balun to get accurate measurements.]  TWR Swaziland has this same model of VIM and it came with a kit of special connectors.  Unfortunately, the special connector that I was looking for could not been found and no one was aware that there had ever been one.

After a bit of searching, I managed to find some parts to make a special connector using a type N cable connector and other parts in the transmitter stockroom and in a back room with plumbing fittings.

The first part used was a 3/4 to 1/2 reducer for rigid copper pipe.  I was amazed -- the large end was a perfect press fit over the N connector and the smaller end was a perfect snug fit over the outside of the probe.

The first part found in the plumbing stock was a 3/4 to 1/2 reducer for rigid copper pipe. I was amazed — the large end was a perfect press fit over the N connector and the smaller end was a perfect sliding fit over the outside of the probe.

This gives some idea of how the special connector will fit together.

This gives some idea of how the special connector will fit together.

The next challenge was to make a contact for the tip of the probe.  I remembered the connector pins that we replaced on the servo motors.  One of these mated perfectly to the probe pin.  The solder end of the center pin of the N connector, that is usually soldered to the center conductor of the coax cable, was then enlarged slightly — just enough for the connector pin (used for the servo motor) to be pressed into it. [Hope to have photos of this in our next blog entry.]

By now, it was quitting time, so we’ll plan to finish this tomorrow.

I did two projects after arriving at our apartment.  The balcony walkway on our apartment tends to flood, especially when rain comes from the west.  I managed to get two of three drains unplugged earlier, but the third one (nearest our door) seemed to be blocked with cement,  It was probably never opened after the concrete forms were removed.  I brought home a long punch this evening.  After a couple taps with the hammer, a 1″ long plug of cement popped out and the puddle of water drained quickly.  No more need to wade out of our apartment!

The second project was replacing the ceiling fan light switch in the second bedroom, where we do all our computer work.  The light switch had gone bad, so we had picked up a replacement switch while in town on Sunday.  After using a table lamp for the past week, It was nice to have plenty of light again!

 

2014/07/22 — Tuesday — Rainbow Greeting

Here is a photo of the beautiful rainbow we saw arching over the transmitter site when we arrived this morning:140722 -- RainbowMy goal for the day was to improve the performance of the PA inductor that I inspected on Friday.  One of two thin shims was removed under one of the idler roller carriers.  The idler rollers now only touched slightly in one spot and the drive shaft of the inductor turned much easier.

This is the shim that was removed resting against the carrier from under which it had been removed.

The plastic splined drive shaft is supposed to move in-and-out freely, but was too tight.  It is supposed to be just tight enough to not allow backlash when changing direction.  Absent a milling machine to slightly widen the slot in the spline, I tried a file, and sandpaper with little success.  Evently, I scraped it with the blade of my pocket knife.  It was a slow, tedious process, but it did the job!

The white plastic drive shaft, at the left bottom of the photo, pulls out about a foot further than seen here.

This evening we took a step of faith and purchased air tickets for our month-long trip to Swaziland starting in mid- October.

2014/07/21 — Monday — Liberation Day 70th Anniversay

We woke up wondering if we would still be going to the Liberation Day 70th anniversary parade.  It had been pouring down rain most of the night.  Everyone decided to give it a go anyway.

TWR staff, that were going to the parade, met at the apartments.  We all went in two vehicles.  Virginia and I rode with Grant and his family and parked just up the hill from the Pacific War Museum on Route 6.  We walked down the hill to Marine Corps Drive (Rt 1) then east to find a good place to set up our folding camp chairs.  We had walked about 1/2 mile when someone from the Lutheran Church invited us to sit under their canopy.  What a fantastic opportunity to stay out of the intermittent rain storms — much better than just our umbrellas!

Thanks to the hospitality of the Lutheran Church, we had some protection from the rain and/or sun.

The parade was supposed to start at 9 am.  It rained fairly heavy until about 9:15 am.  It was about 9:45 before the honor guard reached us.  We were near the end of the route, about 1.5 miles from the start.

Before the parade officially started, bicyclists and motorcyclists drove the parade route.  Out of about 100 motorcycles, only two were not Harley Davidsons.  The flags are showing the direction and velocity of the wind.

2014/07/20 — Sunday — Memorial & Underwater World

Tomorrow is the 70th anniversary of Liberation Day, the day that American forces returned to Guam to liberate the island.  There are commemorations going on everywhere on Guam and the service at Harvest Baptist Church was no exception.  The service opened with a video of the American forces coming ashore on the western beaches.  One could feel the emotion of gratitude for the freedom resulting from that sacrifice, which was being displayed on the screen.  The people of Guam consider themselves American and are U.S. citizens.  One of Guam’s mottoes is “Where America’s Day Begins.”

First this Chamorro adult choir led the congregation in the National Anthem, then sang Guam’s Hymn (their territorial anthem)

After church, I wanted Virginia to show me what she had seen at the South Pacific War Memorial.  She had gone there a few weeks ago, with Kathy and Joanna.  On the way, we stopped by Wendys.

The shortest way from the church to the memorial was the road around the airport.  We decided to take a photo of the welcome sign that is seen upon leaving the airport.  I was asked what I was doing by an airport policewoman, just after taking this photo!
