Research via the Internet By W2ILP [Jean Parker Shepherd, K2ORS
(1921 – 1999)] |
Last
month I wrote about Jean Shepherd. I
spelled his name wrong. It should not
have been spelled Gene Sheppard. I also
spelled Ralphy instead of Raphie and Shultzy instead of Shultzie. This was a clear case of an editor not
editing his own work. There is no excuse for such ignorance. I could have said that I purposely spelled
Shep’s name wrong so that his heirs might not be able to sue me for infringing
on what he had copyrighted. To be
honest that was not my intent. In the
future I will always do some research before I write anything. I have the whole Internet browsing system at
my disposal and I intend to use it wherever possible to help to clear up my own
limited memory. I now use the Google or Yahoo search engines on the
Internet. Both of them seem to give
basically the same results. If your
computer and your ISP are capable of fast operation, you can get information on
almost any person (living or dead) or any subject (scientific or supernatural)
in milliseconds. I don’t know how those
search engines can work so fast. Anyway
when I did a search for Gene Sheppard, I got a lot of stuff about a John
Sheppard, who worked with genes. So then I tried Jean Sheppard and I got items
about a female vocalist. Finally I gave up on Shep’s name and I did a
search for Wanda Hickey. She was one of
Shep’s fictional characters. This led me to many pages of links to the real
Shep. I searched in vain to see if there was a complete speech by Shep that was
the same as I had heard at the Hudson Division ARRL convention. I found two speeches that Shep had made at
Dayton HamVentions. They contained bits
of what I wrote, but not all of it. One
of the speeches was hard to understand because the microphone was not placed
properly. The other was solid
copy. I also found a site where I could
down load many of Shep’s actual WOR radio broadcasts. I could not listen to them all, but I listened to ones that were
labeled “Ham Radio”. I found an
introduction to an ARRL code practice tape that Shep had made. You can listen
to his last impish suggestion and decide for yourselves
why some conservative hams wanted the tape recalled. In Shep’s memory I’ll print:
FLICK LIVES! EXCELSIOR YOU FATHEADS!

Not too much
happening here, we are near
the beginning of March, and it has been a cold, snowy
Winter
so far. The solar cycle is near the bottom, so the DX conditions are not that
good. This is a good time to get on the CW bands and practice code, but for
some reason, I can’t find the time, or I am too tired. Life at “Grumman” is
still good, and the Bethpage campus is very alive. If you haven’t been to
Bethpage in the last 5 years or so, you might be shocked by the changes that
have taken place there. Plants 3 and 5 are still unoccupied. Both were taken
back by the Navy with plans to cede them to Nassau County. But, there is a snag
somewhere, and the County hasn’t taken the buildings. They sit empty, and it’s
been almost 5 years. A few months ago, Facilities people had to go to 5 to
retrieve a piece of equipment. Because
the heat is off , the place is damp and moldy. They had to wear masks to
protect their faces and lungs. Also, the piece of land that was the western
most part of the runway (just west of the new water tower) was sold last year.
That’s why we had to move our Field Day operation off of it. Recently there has
been some heavy equipment on the site. They have been digging up the asphalt
from the old runway surface, and grinding it up for salvage. There’s a few
large piles of black stuff there, but we don’t know if they will erect a
building there or not.
I mentioned a few months back that my
IC706 was acting up. It would get very
“staticy” sometimes when I was listening to the repeater. And when I
transmitted, the guys would say my power level was way down, and they could
hardly hear me. It was an intermittent
problem, but it was getting worse. When it got bad enough that I was sure a
repairman would see it, I decided to send it out to get it fixed. My dilemma
was either send it to Icom or use one of their authorized repair centers, which
they list on their web site. I chose “local”, and used a place in Queens. He
had to resolder some circuit traces, and he called to tell me. Then he sent it
back. Very quick turn around, just a few days. The radio was fine for about a
month, then it started acting up again, but nowhere as bad as it had been. So,
I shipped it back to the repair guy. Of course, on his bench, it played
beautifully. Since I was going to
Florida for a week, I asked him to hold on to it, run it a week, hit it with a
hair dryer, and the Freon, to force some temperature extremes. Now I’m back. I have to call him. I hope he
found something else to fix. If not, I’m probably screwed, and will be unhappy
with my decision to use a local shop, although lots of people here have used
him. They are all pretty happy with his work.
Our February meeting was quite
successful. W2KRM was our guest speaker.
Geopge did a lovely presentation on old radio pioneers, and then demonstrated
his antique spark transmitter. A few of the members then pounded the real
brass, making CW on the rotary spark gap. We have lots of pictures on our web
site, thanks to N2PYV and AB2EF. Our
next meeting will be
At
UL on March 16th. I hope to
see you there.

Internet Link of the Month
I
had promised to print an internet link for “internerds” that is of interest to
hams in each newsletter. Editors note: I have invented a new word: INTERNERD = A
Nerd who uses the Internet. This is no big deal. I have made up words before.
When I find that other people are using my words I feel almost as good
as when people repeat my jokes, and tell them without laughing because I
can’t. If anything I might leave my
words to posterity. An example of a
w2ilp designition:- Citizens’
Multibanders (CMBers ) = No Code+ No
Theory Hams. “CMBers” became a common designation on some ham chat reflectors,
when the ham license requirements were proposed to be changed. I started it. I was a mugwump at the time.
Don’t blame me for anything the FCC finally decided to do.
Last
month I mentioned WinDRM, which is a new digital mode that is still being
developed.
You
can get started with it and get on the e-mail list with those hams who are
experimentally trying to use it by going to http://www.qsl.net/HB9TLK/ HB9TLK is in Switzerland and is the prime
developer. He types in perfect
English. His handle is Cesco. I said
that WinDRM is the same as Ham Dream. Actually they are two different versions
by HB9TLK. WinDRM = Windows Digital
Radio Mondiale. Don’t ask how to
pronounce “Mondiale”. It was debated
internationally on the WinDRM reflector with no consensus. This month I was going to talk about
WinDRM. This is a system to transmit and
receive voice by a digital method. It
can also be used to send still pictures, like SSTV, only better. It is a digital QAM mode.
Before
I go any further I want to thank Dave Ledo, AB2EF for sending me a list of many
web sites where we can download programs that are related to ham radio
communication. The list can be found
at: http://www.qsl.net/rv3apm/
I also want to thank Dave for a link to another
digitized audio system that can be downloaded from:http://www.eSoftAnywhere.com/Install/eSoftwhere-Ham-Radio-DSP.html
I
am trying to use it for audio processing but I see that it can also be used to
transmit audio in a digital mode, so it is like WinDRM, but a different
software program and display. So far I tried it on an AM broadcasting
station. I adjusted the levels so I
could hear the station through the computer’s speakers rather than the radio’s
speaker. I tried to see what the DSP
filter settings could do. I can see
that it will take some learning for me to use the filters to advantage . I will be trying this DSP on the 40 Meter
WAG net, where I always have lots of noise.
I missed the net last Sunday morning because I was busy filtering zees
through my nose at that time and in a dormant standby condition. You need not wait for me to define each link
in this newsletter. Aside from that
you can search Google or Yahoo for anything you may be interested in, so long
as you know what you are looking for. (See
my comments on page 1) It is interesting to see that although many of the
ham programs are free, there are some that require payment. On the one hand the FCC says that hams
should not use any coding methods that are not available free for all hams to
monitor (as well as free for the FCC to monitor). That is because special codes
that require payment from amateurs may be defined by the FCC to be as illegal
as “secret codes” before they are really popular. I myself am not transmitting in the free developing modes,
especially until I can receive in those modes.
On the other hand I understand that it is hard to write software that
relies only on freeware. When we use most programs we are using an operating
system such as Windows. Windows and
other MS programs are not free, even though you get them preinstalled when you
buy most PCs as a part of the package.
If you want to build your own PC legally, you have to buy a Microsoft
programs from Billy Gates or you have to pay for some other O.S. If a ham wants to develop software that
might include some subroutines from special programs he might have to buy the
subroutine programs if it not preinstalled on his hard drive. Maybe that is why
these ham developers are usually in foreign countries. Even if the ham who designed your freeware
pays for the subroutine, that may not enable you to use it legally without also
paying. This is a very murky area. We find similar problems with music
copyrights because it may be hard to write a song that doesn’t use a few bars
from a song that someone else is selling. Obviously programs that cost money
are not going to be popular with the hams, who can get similar programs for
free. When audio and video tape
recorders were first being sold, Walt Disney and others sued the manufactures
because they feared that music and movies could be easily copied and bootlegged
without paying the real source. The
courts threw the cases out and ruled that the recorder manufactures were not
liable for anything that the users did.
The recorders could be used for copying stuff that the users made with
their own microphones or camcorders and that is legal. In other words if the users sold copies of
copyrighted songs or movies it was only the individual users that should be
punished (if you could find them). Recently there has been a reversal and a
court decision said that the manufacturers of DVD copying devices are
responsible for preventing the copying of proprietary stuff. How this can be enforced, I don’t know. We
have seen that proprietary ham programs are harder to win popularity and thus
it is harder to find them on the ham bands.
Pactor I and II are examples of digital modes that require special TNCs
and they are not as popular as RTTY or PSK-31 which can be run using only a
very simple home brewed interface or
the lowest cost RigBlaster. WinDRM
uses only the same simple interface which I built to connect my PC to my HF transceiver
for RTTY, PSK,MFSK and Hellschreiber.
WinDRM requires a PC with a fast microprocessor. It is being designed for Windows XP, but
some hams are trying to use it with older versions of Windows and are having
some success. The other big change that
some hams have made is to add a second sound card to their PCs. HB9TLK has tried to keep WinDRM working with
one sound card, but there are advantages for those who can install a second
sound card in an open slot on their PC’s motherboard. I had bought another Creative sound card some time ago, before I
knew anything about WinDRM. I haven’t
installed it into my new PC yet. I
guess that figuring out my income tax this month has priority. With two running computers and monitors,
microphones, speakers, a camera, a USB drawing tablet, a modem, a telephone, my
simple interface and an IC-706 ham station with power supply on my desk, there
is a rat’s nest of cables behind it. I
have to put a label on my lamp cord to remember what it is for. If I pull the wrong plug I could be lost in
the darkness while crouching on the floor behind my desk and never be able to
find an open socket to plug in the next human interfacing device. I would have to wait for the light of day to
be able to plug and play or to get up without stepping on wires.
GARC VE
EXAMS We are continuing to proctor exams for
all classes of ham licenses on the second Tuesday of each month, starting at
5:00 PM. The present exams are: Element 1: 5
WPM CW, Element 2: Technician, Element 3: General and Element 4:
Amateur Extra Class. The fee for 2005 is $14 for all exams taken in one
sitting. Applicants for upgrading should bring
a photocopy of their present license and their FRN number. New, first time, applicants should be
aware that their Social Security number will be required on their
application form. All applicants should bring drivers license or other
picture ID. The exams are given at the Underwriters Lab in Melville, unless otherwise noted. This is the same building where GARC
meetings are presently held. For any further information e-mail: -
[email protected] or phone: - (631)
499-2214 Study material
information is available at the http://www.arrl.org or the http://www.w5yi.org
web site. All VECs use the same Q & A
pools. Since the beginning of the VE program
the GARC has provided opportunities to take ham exams monthly, during all
twelve months of every year. Bob Wexelbaum, W2ILP and the Grumman VE team. |

while, but eventually I’ll be using only the cable address. I have spoken
to many hams over the years, and have found many differing views about
what ham radio is and what ham radio should be. The two basic areas most
considered are TRADITION and TECHNOLOGY.
Some of us old hams are living in the past. We remember the thrill
of our first QSO and we talk with nostalgia about what ham radio was like
in the “good old days” and how its rules and traditions evolved. Others of us are interested in the
technology of the future and want to learn about the new nano, fiberoptic,
and digital techniques that are
advancing the science of radio communication. I guess I tend to do a little of both. Ham radio is also a social hobby
because it is designed to connect people. I must always remember: Ham Radio means different things to
different people. GRUMMAN

TECHNICAL BITS
I am going to talk about communications systems here and I
will start at the beginning. The
simplest system is the one bit or beacon method of signaling. An example is the smoke from a signal fire. Indians used this method and I am sure that
the ancient people did too.
Now if there is just smoke or there is no smoke that could
be a binary bit of information. One
smoke could be a beacon to mark a location also. If you see smoke in the west the enemy is coming from the east or
smoke in the east means the enemy is coming from the west.
.
No
smoke = no enemy. Anything different is
a different condition. The smoke is
like a continuous radio carrier. The
carrier can serve as a beacon, and it might mark a frequency and be used for
propagation studies, but it can’t carry more than a single bit of information
if it gets propagated from the same location.
We hams call a Morse code keyed RF carrier CW, but it is not a
continuous carrier when we turn it on and off by keying it with a serial
digital code. The Indians could also send codes by turning on and off the smoke
with a blanket. This all sounds very simple but just wait until I get into more
complex communications methods.
We
can use Morse code to send and receive all of the characters that are in the
code. We could also make more
combinations of dot and dashes to transmit more characters than are now in the
code, but we would have even a harder time learning to copy the code by
ear. If we make a code that has a fixed
number of dots and dashes for each character then we become limited to 2^n
possibilities for the different combinations.
Morse code is not limited to a fixed number of bits per character. It has only one bit for “e” and five bits
for each of the numerals. This allows
for more possibilities and makes it possible to send common letters faster. To be continued next month.
