The April Feedback

-by N3GXA

Thanks to those who complimented Mark and I on the New Feedback format. At least this month I have a pretty good idea what things will look like. I have limited access to the Internet, so I haven't looked for the on-line version yet. I may not do so for a long time. Mark has scanned in some photographs for the draft version, and these may appear in the final. We have wanted to publish higher quality photos for some time. Joe/NA3T was one of our best contributors, and he liked to use pictures, but the quality of a xeroxed photo print degrades very quickly. One of the advantages of being editor is that I got to see the color originals of things like the Algonquin dish antenna. I have always felt that the Feedback is the primary source of LARC information for many members, so if we can show a few shots of our activities, like Field Day, it will give a better idea to our friends who just can't make it to these things.

Our March meeting, featuring Chris Imlay/W3KD, was extremely well attended. There were quite a few new members who I think felt welcome, and I would daresay the evening was quite a success. It appears we have 17 new members since our mailing to local hams. So, if you think you're seeing a lot of new faces at the meeting, you probably are, and I encourage you to say hello and introduce yourself. I would also like to point out that with all this sort of activity, Patty and I have been very busy at the meetings and just can't talk to all the people we should, so please let us know if you have fallen between the paperwork cracks somewhere. (After all, Kevin/W3DAD only had to remind me about 10 times to straighten out those Sweepstakes pins.)

I hope you're getting into the habit of posting the Calendar of Events somewhere conspicuous, (perhaps on the front of a major kitchen appliance). This month, we have the updated Membership Roster for 1997. Make sure you save that thing so you can refer to it throughout the months. I still make use of these things from several years back, believe it or not.

Take notice of the Thank You note sent to Norm/K3QDC. He received this from yet another happy customer of the Laurel VEC, and it's very nice. These notes are a not uncommon, but all our long time VEs deserve a pat on the back once in a while. Also be sure to read Kevin's excellent as always article on antennas before you leave for the meeting. If you don't have time, just bring your trusty Feedback to the meeting.

President's Ramblings

As Howard/K3IOG would say, "Busy, Busy, Busy!"

First of all, let me apologize to our new members. I had intended to send a welcome letter and copy of the bylaws to all of you. I hope you will let me get away with giving you a big WELCOME here! I've had the pleasure to meet several of you, and hope to meet the rest of you soon. From the information on the membership applications it looks like you have a broad range of interests and skills. I hope you will not be shy, jump in ask for help or lend a hand. We can always use some new ideas.

You should find a copy of the club bylaws enclosed. I am sending them to everyone since I did not get them out to the new members and suspect some of the other members haven't seen them either, now everyone should be covered. As I write this I don't know how good the copy will come out. We wanted to get a full Feedback out, the bylaws, and the membership list without incurring too much of a postage cost. The reduced copy is either a scanned or cut/paste version. I scanned the bylaws through my OCR software but decided not give out an altered document. Going through I found a couple typos which we should probably correct this year. So, go ahead and read them through, and bring up any suggestions for changes at one of the next meetings.

As you will see mentioned later, the club has picked a 70cm simplex frequency to hang our hats on. Our first official use of the channel will probably be at the Main Street Festival. In the past we have used two 2-meter frequencies, one for general use and one specifically for parade coordination. This has caused some de-sense problems that should be alleviated by moving the parade frequency to 440. If you don't have a 440 HT, I might suggest that you stop by Radio Shack and check out the HTX-404. They are being discontinued and are on sale for $179.95 though April 26. I have one and have been very pleased with it. Joe/N3TZA and Phil/K3MEG had made special arrangements with two different Radio Shack stores to get an additional 10-20% off for a group purchase. Both of these deals fell through on their subsequent visits. Thanks for your efforts guys! And don't forget about John/WB3GXW's 444.250+ PL156.7 repeater or the repeater at MRC (442.500+ as I recall).

If you didn't make it to the March meeting, you missed a good one. Chris' discussion about antenna restrictions was of particular interest to me since I moved to HOA-land last Fall. I just received from my HOA a copy of the proposed changes to the antenna covenants that cover my home QTH . The 'Antenna' section used to be just one line: No outdoor antennas are permitted. The section is now a full page, but the first sentence is: Satellite dishes less than 1 meter in diameter and antennas are permitted. While it goes on to explain all the approval procedures, there is no language about the antennas having to be receive-only or TV-only. Maybe there is some hope here.

I had the opportunity to attend a Foundation for Amateur Radio (FAR) meeting last week, this is a fine group of hams. I had previously thought the organization's primary function was the scholarship program, but they actually are a resource for a much broader range of amateur projects. If you have ideas for projects that are not club specific, but would enhance the amateur service on broader basis, please let Joe/KA3UZI, Dan/KA8YPY, or one of the LARC directors know. FAR may be able to help fund such projects. Tony/WA3YLO of FAR also runs the Widows Program, which sells equipment of Silent Keys - I'll try to get some more information out on this so you can add it your list of shopping resources.

I almost have something that resembles a shack now. I ran into this thing called APRS which has revived my interest in packet radio. I found myself going through my computer graveyard and piecing together a couple of computer systems to get online again. Anyway, you will find out much more about APRS at our May meeting when Bob Bruninga/WB4APR, the creator of APRS comes to speak. Maybe we can even track him to to the club house, I assume that 'Bob's Van' on my map is WB4APR. I'm also hoping to have at least one APRS station and tracker setup at Field Day. I guess part of my interest in APRS is that it is something that kids might think is cool and get them interested in ham radio. Or, maybe it's just for older and slower kids, like me.

Speaking of youth, that is where I am trying to expend much of my effort this year. We have two big public opportunities to hit them: Field Day and JOTA. I'm trying to get the word out to the schools, scout groups, and

other youth groups about our Field Day. This is an excellent opportunity to showcase the many aspects of amateur radio. I'm hoping all of you will really pitch in to make our Field Day a good PR event. Please let Jim/WI3N, Dick/N3MJA, or myself know of any ideas you have for presentations or demonstrations at FD.


Youth Mentors Needed



We are looking to introduce and promote amateur radio to youth through the following avenues:












We need members to develop programs for each of these areas, participate in teaching portions of the programs, and generally provide support and help wherever possible.




Field Day, June 28-29, will be our first opportunity to try out some of our ideas. We would like to have some interesting presentations and demonstrations that show-off the many facets of ham radio.




Please contact Mark/N3NTQ, Dick/N3MJA, or Jim/WI3N of you have ideas or can help out in any of these areas.



I also want to utilize the OASIS program this Fall to introduce youth to amateur radio. The OASIS program runs on Thursday evenings from 6:30-8:30pm at Eisenhower Middle School. Each session runs about 4 weeks. This program provides tutoring and special-interest classes to school-age children. We'll need to start soon to layout a program that should include videos, talks, and demonstrations. We might want to look at the requirements for the Boy Scout Radio Merit Badge and cover much of that material in the classes. This would be a way to get a good set of prospects for the class and get them prepared for JOTA at the same time. ARRL has some good materials that we can use to get the creative juices flowing.

I've probably missed some things, but it's almost 4am on Friday now, so guess I should sign. See you at the meeting, Montpelier, or Main Street. Oh, bring any good show-n-tell stuff, particularly related to Stealth Antennas, to the meeting this Wednesday.

Upcoming LARC Public Service Opportunities



Sunday, May 4 Montpelier Spring Festival


We need to get out there at about 8am, details to be discussed at the April meeting. Please let Roger/W3LM know if you can help out.




Saturday, May 10 Main Street Festival


We need folks from 6am to 5pm. Most our work is from 6am until about 10am. The parade will start at 9am this year. Please let Pud/W3YD or Howard/K3IOG know if you can help out, even for part of the day. Further discussion at April meeting.




Saturday, June 7 Laurel 5K Run/Walk


Will need 12-15 operators, a few at 6am and the rest by 7:30am. Stay tuned for further details. Mark/N3NTQ is the coordinator.




QSY to 445.975


LARC has selected its preferred 70cm band frequency as 445.975 simplex to complement its current 147.540 channel on 2m. Our selection has been submitted to T-MARC for publication. Although T-MARC does not coordinate simplex frequencies , it does note preferred club or geographic area usages.



What about 10 Meters?


It has been suggested that the club select a 10 meter frequency to hang out on. A suggestion of 28.354 has been made. Do we have any others?



Come to the April meeting to discuss further.



Radio Shack HTX-404s on Sale



Radio Shack is discontinuing their HTX-404 line of 70cm handhelds. They are on sale for $179.95 through April 26.

APRS Presentation in May



You may want to dust off and power up your TNC in preparation for the May 28 meeting.

Bob Bruniga/WB4APR, known internationally for his work with the Automated Position Reporting System (APRS) application of packet radio, will be our guest speaker. We are very fortunate that Bob lives in Maryland and has agreed to spend the evening with us.



I think you will find APRS to be very interesting, particularly in the context of the public service and emergency activities that we perform.

Minutes of LARC Meeting - 26 March 1997






Stealth Antennas

Kevin Arber, W3DAD

At our March meeting, Chris Imlay, W3KD, provided some hope for amateurs living in antenna restricted areas. For those amateurs interested in UHF and above there is light at the end of the tunnel. From VHF on down, problems may remain for some time to come. On the other hand, in certain circumstances low profile antennas may be called for even if no antenna restrictions apply. Or, if you have obtained an exception, you may not want to give your amateur station a high profile for other reasons. In any case, some of the ideas below, while not new, may help in accommodating your particular situation.

In preparing these articles I usually outline the article first. This is usually an easy task and it keeps me from straying off the subject, however, I had some difficulty with stealth antennas. I could not easily determine a set of major paragraphs. I finally used, yard, deck and indoor antennas as the major headings, but could have opted for HF, VHF/UHF or e, tubing or some other classification. In any case, there is no clear dividing line between the classifications, and what can be used on the deck may be equally useful in the yard or indoors.

Yard Antennas:

If you have even a small yard, you may be able to have an effective HF antenna for communication out to 300 to 500 miles on the lower bands. An antenna close to, or even on or under the ground, can provide effective communications using NVIS (Near-Vertical Incidence Skywave). An article by Ed Wirtz, W7JGM appearing in the ARRL Antenna Compendium #5, on his results is worth reading. Ed used 100 feet of wire, lying on-the-ground, fed against a copper ground rod and used an antenna tuner with his NVIS setup. The wire need not be in a straight line, but can conform to your particular yard layout. Wire laying on top of the ground may not be convenient. In that case a slit can be cut in the grass and the wire laid in the slit. Soon the grass will cover the slit over and it will not be noticeable. If your neighborhood allows radio controlled dog fences, which employ buried wire, then they should not object to the buried NVIS antenna.

If your yard is fenced with a wooden fencing, then a wire can follow the fence. There is no need to create a center-fed dipole, however, remember that the wire will have high and low voltage points existing along them and you will likely find it easier to feed it at a low voltage point (1/4 wavelength, 3/4 wavelength, etc.) rather than at a high voltage point. In this case, since the wire is above ground and accessible to others, caution should be used that someone does not inadvertently come in contact with the wire while you are transmitting. Using insulated wire would be prudent.

Vertical antennas can be very effective over the HF band if installed over a ground plane or counterpoise. If a tower is out of the question, but a small structure is permissible, then a commercial antenna such as the Cushcraft R7, Butternut HF6 or a GAP vertical could be erected. These antennas are under 30 feet high and can be anchored easily to a 6-foot fence post. They are visible, however they are unobtrusive. I have used verticals for all my HF operating for many years with good results. Another option is a mobile whip. This may be especially effective if operation is on the upper HF bands and the whip can be mounted several feet above ground. For a stealth antenna experiment, I mounted a whip antenna at the top of a 6-foot fence post and ran a counterpoise consisting of two radials under the antenna. I was able to work many stations, including African and European DX, with this antenna over the late February and March time period.

Deck Antennas:

A mobile whip can be mounted on a deck railing as easily as on a fence. A C-clamp can be used to hold a mount tight if screws are not permitted. For better concealment, mount the base of the antenna at floor level. The difference in height will make little difference in overall performance. VHF and UHF vertical antennas designed for mobile use will also work well if placed on a deck. Magnetic mounts can be placed on metal tables, or a short counterpoise used. There is no need to use the traditional four radials as only two are necessary; even one may

work. Make the radials equal length, then adjust the antenna length for best SWR. If you have difficulty getting the SWR under 2:1, unbalance the counterpoise. Shorten one of the radial wires by folding it back upon itself until the SWR is lowest. This will likely result in some radiation off the counterpoise; but we are not interested in a clean pattern, just getting some RF into the ether.

At VHF and above, antennas come down in size to the point where you may be able to use a tripod mounted Yagi. The Cushcraft 11-element 70 cm yagi is only 56 inches long. If you have a clear view to the North and South many QSOs would be possible during contests and some casual operation would be successful. Combination antennas for 70 cm and 2 m can be constructed on the same boom.

Deck mounted antennas will work well for satellite operation, provided the satellite is not blocked from your view. For the Phase II satellites (RS-10/11, 12/13, 15, 16, FO-20 and 29, and the Microsat digital satellites) vertical J-pole antennas work well for close-in passes. Combination 70 cm and 2 m J-pole antennas can be mounted as a collinear unit as described in the ARRL Handbook, 1994, page 23-27. Total length is only 61 inches. A dual band indoor J-pole with receive preamplifier is described in the January/February issue of the AMSAT Journal. Yagis or other gain antennas may be needed for low horizon passes. Yagi antennas will have to be repositioned as the satellite changes its position in the sky. However, at the beginning and end of the pass, the azimuth angle change is relatively small permitting full attention to be given to making QSOs. At L and S band the antennas are very small and a dish can be used. An 18 inch dish will provide about 16 dB (50% efficiency) of gain at 2 GHz. A satellite operation with a 1.2 GHz uplink and a 2 GHz downlink is being touted as the way to go for P3D. Both antennas could be mounted on a camera tripod, pointed at the satellite and not moved for long periods of time, thus permitting relaxed operation.

For local FM simplex, repeaters and local packet BBS a minimum antenna is usually sufficient. Any of the ideas above will work, however, a low profile 1/4 wavelength antenna or a short mobile is sufficient. The J-pole made from 300 ohm TV feedline is useful if you would like to hang an antenna from an overhead flower-pot hook. These antennas can also be stapled or taped to an external wall, but may need some after installation tuning.

Indoor Antennas:

If you happen to live in a multi-story condo, then the ideal place for an indoor antenna is in the attic. A dipole for 40 meters is slightly less than 70 feet long and may be accommodated if the ends are bent or folded back on themselves. Linear loading of the antenna is also a possibility, or loading coils / traps can be used just as if the antenna were outdoors. I have had many HF QSOs, including DX, with hams who were using indoor antennas and only a 50 or 100 watt transmitter. During the peak of the last sunspot cycle I was able to work many Japanese stations on the 10 meter band who were using indoor antennas. Attic antennas can be strung between corners of the attic or stapled to the rafters. Because of the proximity to other objects they will likely have to be pruned to resonance for the chosen band. If your attic is situated such that the rafters are broadside to Europe or another favorite direction, then a wire Yagi is possible for the higher HF bands. The attic could also house VHF and UHF antennas for local, terrestrial or satellite work and may be large enough to rotate a small VHF Yagi.

Using indoor antennas in the living space of the home may be more of a problem, however, a couple of ideas come to mind. If your home has large glass patio doors, then a VHF/UHF antenna can be taped on the glass. Conductive tape is available for this purpose from HAMCO, A2, PO Box 25, Woodland Park, CO 80866. A loaded-loop HF antenna, sometimes disguised as a box fan, can be placed in a window. You may also experiment at VHF and above with slot antennas using aluminum foil pressed against window glass or as a slot in a metal screen.

Whatever you try, you should be successful enough to be encouraged to continue. Part of the fun of amateur radio is in experimentation with different ideas. Try some of your own.


Recent QSTs Wanted


Please let me know if you have recent QSTs, less than 2 years old, that you would like to part with. I want to provide them to schools, libraries, and other public places with a LARC label on each.



Don't throw away your old QSTs yet. I am hoping to build sets of them to provide to schools and libraries later this year.
