Cherryville Repeater Association Memorial Scholarship Awarded

 

      The Cherryville Repeater Association (CRA), an amateur radio organization that has been providing communications services at public service events and during local emergencies in the Hunterdon/Somerset/Warren tri-county area for over 20 years, announced at their April 14th club meeting held in Flemington the selection of a Hunterdon County youth as this year’s recipient of their memorial academic scholarship.

 

      The recipient of CRA's Year 2000 Memorial Scholarship is Maria Russo of Lebanon Township.  The amount of the scholarship award is $500.00.

 

      Ms. Russo is the daughter of Peter and Annette Russo.  Her father is a longtime member of the Cherryville Repeater Association.  Maria currently lives at home with her parents, and will graduate from Voorhees Regional High School this June.   

 

      Maria displayed both academic excellence and has participated in many high school and church activities. These attributes, along with other criteria, were used by the scholarship committee during the decision making process.

 

      At the May 12th meeting the scholarship committee will present Maria with her award.  On the Scholarship committee are club members John Crovelli, Elaine Langdon, and Patrick Mauro. The Club President, Rob France, will present the winner with a scholarship certificate as part of the award ceremony.

 

      The CRA memorial scholarship honors the memory of deceased club members.

NEW SCI FI HAM FILM

 

      The new sci fi film "frequency" at the local movie.  This film gives an interesting twist to ham radio, and is sure to appeal to all radio buffs--especially if you grew up with heathkit equipment (was it an sb303 that they showed in the movie?).  If you liked the "back to the future" series of time travel movies--you will really like this new movie.  Enjoy!

DXCC DESK ACTION

 

      I received this email just a few days after sending my cards to the League by UPS, thought some of you might find it interesting:

 

Hi Keith!

I am a fellow NJ Ham (from "down the shore".) I had a few days off this week so I drove up to Newington CT for the first time to check things out and to have 113 cards checked for my first DXCC. (Two cards were duplicate Russian entities, so I wound up with 111 confirmed.) Got my certificate right there!

 

Anyway, while Bill was checking my cards I saw your stack on his desk. I assumed you were from "5" land but then I noticed you were from NJ so I thought I would e-mail you to let you know your cards are safe and sound at the DXCC desk!

73,

Tom N2LDE

Duncan will be a participant in this event, so you get a bonus if you come out for this event!

 

4th of JULY PARADE

      The Lebanon 4th of July Parade will be, you guessed it, July 4th in Lebanon. Come join the fun, have some hot dogs and beer (root or regular), see the sights, and show your patriotic and club spirit. 20 people are needed!

 

MARCH OF DIMES WALKATHON REPORT

      A very nice day, sunny and warm, but very very windy. It  seemed they had a slightly smaller turnout than I remember in previous years, although this is the first time I have been to it at this location. (Compared to the Triathlon, the parking lot and crowds were very small.)

      The event went off without a hitch, the most excitement being one of the ambulances taking a call for a rescue from the reservoir for a boating accident.

American Lung Association seeks

hams for 2000 ''Big Ride''

 

      The American Lung Association is recruiting ham radio ''communicators'' to assist in its Big Ride Across America 2000. The 2000 ride--only the second to use ham radio operators--is the third annual event to raise money and awareness for the American Lung Association's fight against lung disease.

 

      It's a 3500-mile bicycle trek from Seattle, Washington, to Washington, DC, from June 19, 2000 to August 5, 2000. More than 850 cyclists have raised in excess of $7.2 million during the previous rides.

 

      Details are available at http://www.bigride.com. Volunteers can sign up for the entire Ride or choose from one or more segments of the country. The direct link to volunteer information is http://www.bigride.com/Get/get.html. The Crew Registration Form on that page lists the segment dates and locations.

 

BOARD MEETINGS

TIME CHANGED

 

      The board and I decided that we need to adjust the time of the board meeting back to 8:00pm. 

 

 "Board meeting: Wednesday prior to the second Friday of the month, 8:00pm at the Hunterdon County EOC. Please note that board meetings are always open to the general membership." 

 

       We want to stress that board meetings are always open and that all members should feel welcome. We'd love to hear from them. 

 

      We are not going tho change the general membership meeting time on Friday. The time will remain set at 7:30pm.  

Thanks, Rob

Antenna Construction

New Antenna Conductor Material

for Efficient Very-Small Antennas

 

      One of the all-time favorite topics of discussion among Hams is antennas. Most of us probably think that towers, beam antennas, wire antennas, etc., are rather attractive. Unfortunately, it seems that many of our neighbors don't share in this opinion. In fact, some of them think that antennas are downright ugly and detract from their property values. Also unfortunately, it is a fact that antennas are required for both the transmission and reception of radio signals. Given these conflicting pressures, it is only natural that there is a lot of research being done on how to make antennas smaller, yet not make them inefficient. We can see this in the proliferation of such miniature antenna products as the Isotron, the Super-C, the Crossed-Field Array, the Contrawound Toroidal Helical Antenna, etc. There have been a lot of wild claims made recently about such miniature antennas, however, when put to the test, many of them perform about as well as dummy loads. 

 

      Recognizing the great need for a truly high performance miniature antenna, I set out to invent one for myself. Being an engineer, I approached this problem logically and mathematically. There is no physical law that forces small antennas to become inefficient. A very short dipole antenna has a gain just slightly less than that of a conventional half-wave dipole. This is not due to inefficiency, but to a slightly different radiation pattern. In practice, the reason that very short dipole antennas become inefficient is that the radiation resistance becomes very small with respect to the resistance of the metal (Copper, Aluminum, etc.) that the antenna is constructed of. Consideration of this led me to the conclusion that there are at least two ways to go: 

1. Increase the radiation resistance of a small antenna, or 

2. Decrease the resistance of the metals from which the small antenna is constructed. 

I could see no way to attack the first alternative, therefore I decided to investigate ways to decrease the resistance of the metals. Suddenly, the light came on: the reason that the metals used for antennas have significant resistance is that radio frequency currents flow on and near the surface of the metal. In other words, radio frequency currents utilize only a small fraction of the available cross-sectional area of the metallic conductor, and as a result, flow through considerable resistance. It would be nice if somehow, we could attract the current toward the center of the conductor, and utilize as much of the conductor's cross sectional area as possible for the radio frequency current flow. How can we fix this? It is well known that the current that flows in metallic conductors consists of electrons, and that electrons are negatively charged. Negative charges are attracted by positive charges. If there were positive charges in the center of the antenna conductor, then some of the electrons that normally flow on or near the surface would be encouraged to travel nearer the center. 

 

      I had my lab assistant construct a special conductor for use in high frequency radio antenna construction. This conductor was made in a way similar to how ordinary electric fence wire is made. The difference was that the inner portion of the wire was made from a highly p-doped semiconductor material (similar to what is used for the bases of NPN transistors), rather than the Steel material used in electric fence wire. This then was coated with a Copper layer. The ratio of the semiconductor radius to the thickness of the Copper layer was about 1:1.

 

      By now, you probably have grasped the basic concept: the RF current that flows in the central portion of the special conductor is composed of positive charges, which is the mechanism by which current flows in any p-doped semiconductor material. At the same time, the RF current that flows in the outer Copper layer is composed of the usual negatively charged electrons. Since the positively charges flowing in the center attract the negatively charged electrons that are simultaneously flowing in the outer layer, this attraction causes the electron flow to spread more deeply into the Copper, and the resistance of the conductor at radio frequencies is dramatically reduced. 

 

      I wanted to give this material the ultimate test. Therefore, I built a center-fed dipole from it, and cut the length of the dipole to 1 foot. I then mounted this dipole on top of the mast that already existed on the roof of my house. It was about 35 feet off the ground. I tried transmitting with it on 160 Meters, but the SWR was outrageously high! However, my trusty antenna tuner soon took care of that minor problem, and I was successfully delivering 100 Watts of RF power to a nearly invisible 1 foot long dipole antenna on 160 Meters! I waited until it got dark, and then I held the key down. I sent my XYL outside to look at the little dipole. It did not start glowing red or melting! Therefore, I decided to jump in the pile-up for the Clipperton Island DXpedition. They came back to me on the very first call with a 599! Wow! That's the real proof-of-the-pudding, eh?  I am uncertain whether to market the material, or the antenna. Please send me your opinion as soon as possible.

OO notice

 

      The following actually on a repeater in central Jersey a few weeks ago. One ham was telling another how he had missed his chance for the upgrade sessions on April 15th. There was a third party listening to the conversation. The calls are left out to protect the innocent…

 

Ham: 'oh screw it, maybe next time'

OO: I am an OO and you just crossed the line

Ham: what do you mean?

OO: you said the S word

Ham: I did not say the F word, I said screw it

OO: not the F word, the S word and you just did it again.

Ham: I said what?

OO: the S word

Ham: you mean screw it?

 

      This went on for a few more rounds, getting more incredulous. A few days later the Ham received an official post card from the OO for his 'infraction' of FCC rules.

 

      For those who are not aware, OO stands for ‘Official Observer’. OO’s are hams who volunteer to watch over the ham bands for infractions of FCC rules. On the HF bands, they often watch for people operating out of bands for which they are licensed, or out of the bands altogether. Many contesters and DXers have received an OO post card for operating too close to the band edge.

 

 

What a difference an antenna mistake can make!!!!

 

      I  thought I was RF challenged down in this canyon  ( I get absolutely no FM radio reception here) so I didn't think much about my 40 meter dipole having a BAD feed line configuration.

     

I cut some nyties and set it up again and then WOW...... reception increased 100 fold. My RFI problems also stopped and my computers stopped crashing when I keyed more than 10 watts.

 

      So... I edged up to 50 watts and made a contact in New York. New York was always off limits before...I never get New York. I think it worked. I had worked CUBA with 6 watts so I really didn't mind running low power because higher would blow my computers up.

 

      Are conditions absolutely gangbusters tonight ?  or was I always supposed to hear  CW on every frequency between 7.105 and 7.120    and      7.010 and 7.058     at  1AM in the morning? suddenly ......  I feel like it’s crowded here.

AN OLD HAM RADIO JOKE...

 

Ham 1: Hey did you hear that ol' Smedrick KB3ZZZ died last week?

 

Ham 2: No! That's too bad...what did he have?

 

Ham 1: Oh, an FT1000, an Alpha 77, a TH6 and two elements on 40....
