New President, New Year of Meetings

Hello All,

Well a new year has began for the club. We are happy that Rich has made himself available to be President of the Elmira Radio Club. The same goes for Tom who is now the Secretary. The position of Treasurer has remained under Reg. The posts of Vice-President and Trustee have not been filled. Hopefully someone will step up to the plate and fill these positions. We like to thank Alan for his years as President and under his leadership the club has become the better for it.

Al was presented with a plaque during the last meeting. Unfortunately the picture of the presentation I took did not turn too well. I will forward it to Bob to see what he thinks of it.

Rich is pushing the county of Woolwich to accept the ERC as the people to turn to in case of communication difficulties in an emergency. On Oct0ber 04 we will have an emergency training to see from which emergency centers we can operate from. As of to date, seven centers have been selected to operate from. The exercise is fairly basic, just to see if we are reachable from these centers.

Election Time

Gentlemen,

 

It is time to step up to the plate. We could not complete our May elections as there was no one who volunteered for the Presidents position. We will try again at the June meeting. It is not hard or difficult to be in the President’s position, as a matter of fact you will have all the support that you need. We just need someone to be running the show and the monthly meetings. Rather than to follow Al’s great example, we might get in speakers and have perhaps have social hour at each meeting. Here we can informally exchange ideas. We have now 41 members, and we should not remain rudderless.

All positions are filled, we even have a Trustee this year.

For now it looks like as follows:

 

President: unfullfilled

Vice President: Johan (until a replacement can be found)

Secretary: Tom

Treasurer: Reg

Trustee: Al

Emergency Coordinator: Rich

This is your slate for the 2014-2015 season.

 

 

 

Name & Call SIgn

I never finished the Name and Call Sign page. The idea was that we could have some pertinent member information there as well as our membership list. The page is password protected and one need to log in in order to access the information. So I do not want to make some complicated and cumbersome, as in the end someone need to administer the details. In an email I will propose something, no need to do this here in an open forum as NSA has enough to do.

Crown Antenna

The idea of the crown antenna came from the UK. Mr. Carl Mason GW0VSW, developed the idea and Dennis VE3UTN used a modified version of it during last year’s field day. It was a smallish affair and the height was around 2′ and 6′ despite the small area Dennis used it successfully in digital mode. I believe that Dennis received close to 80 contacts. The drawing below is showing Carls’ attic version. The high peaks are at the gable ends and the low peaks are along long end of the house.

GW0VSW, CROWN wire loop antenna

In order to experiment further with this type of antenna a new one was setup at Johan VA3JBO. This time the crown antenna was vastly expanded, it measures 68′ by 34′ (20.7 m by 10.3 m) and the low points are 2′ (0.6 m) of the ground and the high points are 12′ (3.66 m) of the ground. The total wire length is close to 245′ (74.7 m). The antenna is corner fed using a 4:1 balun and the coax cable used is a piece of LMR400 of 120′ (36.6 m) in length. The radio used is a Yaesu FT897D. Contacts were made to Washington state and Georgia during a recent contest. Both stations reported 5 over 9.

Friday, September 27. Three members came out Al VA3TET, Bruce VA3QB and Dennis VE3UTN were present and brought with them the field day radio (since this is a tried and true transceiver they felt more comfortable using it). Again several contacts were made as far away as Germany. This fellow came booming in as he was using 500 watts. After trying for several more hours it became apparent that the something had to be done to improve the radiating qualities of this antenna.

Saturday, September 28. Well Friday became Saturday and Dennis made a few more contacts. After some fruitless hours Dennis changed the feed point from the corner to the center of the long end (the antenna was fed from the north/east corner and is now moved to the south/east center). It apparently made some difference but not enough. Dennis was of course disappointed with the results (and he may not like it that I am telling) but he asked me to remove the pictures, however I believe that they should stay as this is what experimenting is all about. In the end they will tell a complete story.

Remarks. The next step is to square up the antenna so that we have equal sides of peaks and valleys. Meaning a 68′ by 68′ square.

Tuesday, October  01. Changed the rectangle configuration to a square one. We now have an equal number of peaks and valleys on each side. Each section of angled wire measures 20′ in length and there are 16 sections, thus a total of 320′ of wire.  I know that one side of the square is 2′ short due to my deck being there. For those mathematically inclined we have actually only 318′ of wire.

We now have to wait for radio to be back here and then we can continue testing. The loop is still center fed. So can change one more parameter (connecting to a corner) and then I guess we are at the end of our song.

Wednesday, October 02. Reconnected the balun and connected the antenna to the transceiver. Not much going on around 14:00 – 15:00, tried again at 17:30 and got a hold of someone in Sao Paulo, he repeated my call sign but then conditions worsened and could not get him back. Pity. Again at 19:00 and the airwaves were full with American stations, could not get a word in edgewise.

The low point of the crown antenna is 2' of the ground

The valley is 2′ of the ground

 

The peak is 12' of the ground

The peak is 12′ of the ground

The area is: 4624 sq. ft.
Length: xxx, Width: xxx

All four sides now 68′

 

Tower Climbing Safety Gear

I was recently present at an antenna and tower take down. I observed that the people climbing the tower were using a “Shockwave Lanyard” as a safety rope. This is a dangerous procedure. The shockwave lanyard is a folded up and sewn together lanyard. If one falls of a tower the thread is meant to break thus slowing the fall of the climber. If this lanyard is used as a safety rope it is conceivable that the stitching may give away and the climber will find himself “falling” away from the tower.

The lanyard above is clipped to the large D-Ring at the back of the harness. The lanyard below is clipped to the rings on either side of the belt.

The lanyard below is a safety working rope. The large clip is clipped to the leg of the tower and the two smaller clips are clipped into the safety belt.

Cell Phone Tower Locator

This is an interesting web site. It will show you where cell phone towers are located and who owns the tower. This might be good information if or when moving into a new area.
