everyone out there for their opinion on our new
meeting methods. I think it has opened up some great
possibilities but I want to hear what the membership
thinks. Feel free to send me an email and let me know
your thoughts.
K1VDH
May is already here! Start warming up you
voices and fists, we are close to Field Day; less than two
months away. As always we are looking for band
captains for Field Day. You can contact anyone on the
board and let us know what band you would like to run.
The June meeting will be our summer VE Session and
Field Day planning meeting.
Every meeting we ask about awards and of late
the response has been nil. Just want to remind
everyone of the great awards that are out there from
the ARRL. We have a fairly diverse membership and
when you mention awards it seems everyone thinks big
like DXCC. Well there are quite a few others some
lengthy, some not, and one that you don’t even have to
be a ham to achieve. Worked All States (WAS) is a nice
challenge. You can work the 50 states in any
combination of mode and band to be eligible and then
work on the harder single mode or band endorsements.
Worked All Continents is a nice stretch for the avid HF
operator. Anyone that can copy W1AWs morse code
qualifying runs with a solid minute of copy is eligible for
award. Check out the league website for a schedule and
give it a shot. Take a look around on the League website
there are other awards and details on these. Get out
there on the air and give it a shot.
It has been a few months now since we
changed up how we meet and I just want to ask
Just a reminder regarding QSL Cards: Over the
past month the US Postal Service has increased the
charge for mailing postcards by 1 cent. So when you
send out that QSL card remember to put 29 cents on it.
Look forward to seeing everyone at our May
meeting where we will get to check out the Bergen
County EOC and all of its toys. Should be a high interest
meeting; see below for the details and address.

by Howie WB2AWQ More News from 7 Land ……
Antenna work continues here in the High Sierras. The weather is moderating, the daytime temperatures
are reaching into the 70s occasionally, and it appears that the snows have ceased here below the
mountain peaks. The higher elevations above 9000 feet or so are still subject to snow. Time to get
cracking on antennas.
First, with landscaping starting in a couple of days, I have to disconnect my 80M and 40/20M dipoles and
roll the coax up until the yard work is done. To fill the void (and to satisfy my curiosity), I’ve embarked on
construction of two magnetic loop antennas. I will reinstall my dipoles, but the loops seem like a nice
thing to have on hand.
Why a loop? Magnetic loops are small, relatively speaking, they are efficient if tuned properly, and can
compare favorably with a dipole in performance. And, they work reasonable well even when mounted
close to the ground, and require no ground radials or counterpoises. No, they will not make you the DX
king, but they WILL get and keep you on the air.
These are the small circumference jobs, similar to the MFJ loop. The first one I built covers 40, 30, and
20 meters. It is made of ½” copper pipe and fittings, and is 5 feet per side in a square, and a variable
capacitor. A circle is the ideal shape for a loop, but ½” soft copper tubing is too flimsy for this size, and
¾”, if you can find it, is pretty pricey. You could make a loop out of wire, but with small loops wire would
constitute too large a portion of the overall resistance of the antenna.
40-20 METER MAGNETIC LOOP HANGING ON MY FENCE. JUST 5 FT PER SIDE
There is nothing magical about this loop, standard construction as per the ARRL Antennas book.
Components are readily available at any good building supply outlet except for a variable capacitor,
which can be fabricated with parts from the same outlet. All pipe joints are soldered, and the variable
capacitor is special – the plates, both rotary and stationary, are soldered to their respective supporting
members. The spacing between the plates is about .09 inches, good for at least the 100 watt level. For
those who are not familiar with small loops, their radiation resistance is extremely low, meaning that very
high voltages and currents will be developed around the loop – we’re talking tens of kilovolts and tens of
amps of RF, hence the need for high voltage rating on the capacitor, soldered, mechanically strong
joints, and large diameter conductors (the pipe).
Gain and directionality aside, there are three desirable factors in any antenna – efficiency, large
bandwidth, and small size. And you can get any two of the three with most antennas, but not all three at
once. The loop is small, and properly tuned, it is efficient, so the factor that suffers is bandwidth. As
expected, this loop, on 40M, is good for about 40Khz at the 2.5-1 SWR limits before the capacitor has to
be readjusted. 30 and 20M are a bit wider, but not much. While this could be a problem for some, my
operations are almost exclusively CW, and 40Khz of territory is fine with me.
Some people equip the variable capacitor on their loop with a motor drive so it can be tuned remotely. I
haven’t gotten that far, but plan to do so. For now, though, I am limited to hand tuning if I want to change
bands or even frequency ranges within a band. That part is a little inconvenient. But it keeps me on the
air.
I’ve also built a smaller loop, about 3 ft in diameter, to cover 17 through 10 meters. This loop is small
enough to work well with soft tubing, meaning I can get close to the optimum circle design, constructor’s
concept of a “circle” notwithstanding! The capacitor for this loop has to go from very low capacitance, a
few pF to about 100 pF, so to get that I used a dual section transmitting capacitor with 200 pF per
section, wired in series. The series wiring does two things – it lowers the minimum capacitance to about
8 pF, while the maximum capacitance is 100 pF. It also doubles the total voltage rating of the capacitor
assembly, again giving a total gap of about .09 inches.
17-10 METER MAGNETIC LOOP – JUST 3 FT IN DIAMETER
Both loops are fed at the bottom, opposite the capacitor. The large loop uses a gamma match (often
used on a beam), consisting of an 80 pF fixed capacitor in series with about 18 inches of wire, the far
end of which is attached to the loop about 30% out from the ground of the connection. The smaller loop
uses a simple smaller loop inside the main loop. This loop is about 18 inches of #14 solid insulated wire
in a 2 X 8” rectangular shape and connected across the coax feed line. Either method is satisfactory so
long as the SWR at resonance is lowest at the middle of the loop’s operating range, and is close to 1.
With this accomplished, the lowest achievable SWR should be 1.5 even at the ends of the loops
frequency range without further adjustment.
From this point, tuning a loop is straightforward. With your transceiver set to your band of interest, the
capacitor is adjusted for maximum receiver noise. This will put the loop very close to the desired
frequency range. A quick exploratory check of SWR up and down from your intended operating
frequency will confirm if you have to increase or decrease capacitance to obtain a reasonable SWR. A
little tweak if necessary, and you are set to go.
A loop antenna displays some specific signal patterns. Unlike a dipole, whose signal is ideally strongest
broadside to the antenna, a loop has its maximum signal lobes on a plane with the loop. Also, unlike a
dipole, which radiates SOME signal off the ends of the antenna, a loop has a very sharp and deep null
broadside to the loop. For me, to work the east coast direction, my loop has to be on an east-west plane,
while a dipole would be on a north-south plane.
I’ve also installed a random wire from the shack, out the door, and up along the eave on one side of the
house, and a counterpoise running along the foundation of the house. This antenna, being end fed and
some 70 ft long, will be very low impedance on 80M, somewhere near 50-100 ohms on 40M, and high
impedance on all bands above that. This necessitates the use of a tuner. My choice of tuner circuits is
the Ultimate circuit, developed in the 60s. I built this tuner several years ago, and used it in NJ. It
consists of a roller inductor, a dual section 300 pF per section tuning capacitor, and two 200 pF
capacitors in parallel for output tuning. I can load the antenna up on any band, although it takes a few
minutes. Band changing is NOT quick with this method.
THE WB2AWQ VERSION OF THE ULTIMATE TRANSMATCH
In the March 2011 issue of QST (their annual antenna edition), a design caught my eye, a Near-End-Fed
dipole. This is nothing more than a half wave antenna fed very near one end, through the use of a 16:1
balun. I built one for 20 meters, and it works OK. While it is no different from the dipoles in performance,
it offers me another option for locating and feeding some wire. I used a spare Amidon FT240-43 toroid
core to construct the 16:1 balun. A 4:1 turns ration gives 16:1 impedance. This means 50 ohms in is 800
ohms out, which on a half wave antenna would be about 3% from one end. This would make a dandy
portable antenna – you hang one end up high, and the other end need not be too far up, meaning a short
feedline, with no ground needed. Pretty neat and VERY simple. I’ll have to experiment with this one to
see if it could be made into a multiband job………
BUSINESS END OF THE NEAR-END-FED DIPOLE
Last but not least, for no particular reason……….

Herb N2OPJ on SDR
Computer Controlled Radio aka SDR Software Defined Radio
Probably back around 2000 I said I wanted to get a Computer Controlled
Radio called a Kachina 505DSP designed and built in USA (I wonder where
that country is???) since everything then was mainly Japanese. The cost then was $2,150 a tidy
sum of money then. My plan was to save up and buy one. Alas my plans fell apart May 16,2001
when they discontinued manufacturing of the 505DSP.
The next near item that really interested me was the Icom PCR1000 general coverage receiver.
AM/FM/CW was the modes available no SSB This receiver covered 100khz through 1.3 ghz
(1300 Mhz) This was all contained in a black box the size of a hardcover book. The display on
the computer monitor was a dedicated size that had resemblance a receiver. The jack on the left
was a DIN 9 which ran a cable to the computer a BNC connector connected whatever antenna
you wanted to use or the supplied telescopic aluminum whip antenna. A small speaker was
inside the box or another jack allowed you to connect up a better pair of speakers. On
installation you had to decide what you were going to use for speakers internal or external. The
internal speaker was not worth using at all as it had low audio. In order to switch between
internal and external speakers you had to disconnect everything on the black box remove a
good amount of tiny (2-56 maybe) screws to remove the top cover. Get a magnifier to find a tiny
DIP switch to move over one position.
The display was actually a set of boxes above one
another that you could click and drag around.
Frequency display with mode, amplifier and a
band-scope which just displayed plus or minus a
center frequency. There was absolutely no way to
click on the stronger signal and drag it to center to
tune to it.
After several years with this I put it on e-bay got
about what I paid for it and parted with it.
I always held an interest in what later was to become SDR
Software Defined Radio’s especially the Flex-Radio SDR1000 12Khz to 60Mhz 160M to 6M bands a transverter for
2m was available. the output originally was only ONE watt
upgradable with a module for 100 Watts dependable on
mode and frequency later units were all 100 Watt. This
unit was rather cumbersome with numerous cables etc. I
read many articles on this right from the engineering technical to the mundane what it did and
what it did not do. Many of these SDR-1000’s are still in service today. Now they have four
different models available.
The first is the Flex-5000A pictured above for those with an existing computer in the shack that
will handle this rig. More on minimum computer requirements later. For those that do not have a
computer available they manufacture the Flex-5000C one that is twice the size that has the
computer already built in. Pictured below.
This has now given birth to the Flex-3000 below. This radio is Blue in color all others are black
and silver. They held a vote on three different colors before the rig came out in Blue. Yours truly
voted Blue.
These radios have an output of 100 Watts the Flex-1500 (below) is a total different type of rig
with a different purpose totally as the power output is 5 Watts. This rig is for the QRP lovers out
there. It is known as QRP SDR.
The 1500 is suited to be the ideal IF deck for VHF-Microwave operation.
The operating modes available are USB, LSB, DSB, CW-L, CW-U, AM, SAM, DRM, DIGI-U,
DIGI-L, and FM (narrow). All power outputs are Full Duty Cycle.
The 1500 sells for $649 the 3000 is $1,699 the 5000A begins at $2,799 user upgradable to have
two receivers $649 add the Autotuner $299 (which I have) The VU5K module is available as a
factory install $1,246 giving you 144-148 MHz and 430-450 MHz all mode 60 watts output. Now
for those that must have a knob The Griffen Power Mate is $55.
The Griffin Knob (left photo) is a multi function tool that plugs into an
available USB spot on your computer. This knob has numerous functions I mainly
us it for tuning if needed but I prefer the click and drag your signal method.
(CAUTION: If you install this knob on your computer for the Flex it may also do
something else in another mode such as MUTE when I was on PSK-31 taking me
off the air)
In several articles I intend to cover what the radio does and the basic functionalities that you
have available on the display. Flex is constantly upgrading software (FREE OF CHARGE) for
the radio thereby giving you a totally new radio with every download. The first version (below)
that I had the display was simple as below the new display is similar in layout but looks more
like a radio. Enjoy the below for now till I write the next article.

This ham plate is rare in that the state almost invariably refused to issue call signs without the US or LA
stacked prefix. I know of only 5 or 6 that the state allowed. When the US or LA were added it made the
