you ever wondered why radio amateurs are called “Hams”? Well it goes like this:
The word “Ham” as applied in 1908 was the station call of the first amateur
wireless station operated by some amateurs of the Harvard Radio Club. They were
ALBERT S. HYMAN, BOB ALMY, and POOGIE MURRAY.
At first they called their station “HYMAN-ALMY-MURRAY”. Tapping out such
a long name in code soon became tiresome and called for a revision. They
changed it to “HYALMU”, using the first two letters of each of the names. Early
in 1910 some confusion resulted between signals from the amateur wireless
station “HYALMU” and a Mexican ship named “HYALMO”. They decided to use only
the first three letters of each name, and the station call became “HAM”. In the early pioneer days of unregulated
radio, amateur operators picked their own frequency and call letters. Then as
now the amateur stations had better signals than the commercial stations. The resulting interference came to the
attention of congressional committees in
APRIL FOOL! I don’t know if the above
article was in an APRIL issue of “
A ham who called himself Bubba had another theory to add to the Deja thread. I don’t remember Bubba’s call letters. His theory went something like this:-
Some early Ham leaders in
In my opinion it is a good thing we are
not called “
Now back to why we are called “Hams”. The word “Ham” was initially considered to be a derogatory title for a radio amateur. Many amateurs did not want to be called “Hams”. (There are now some Hams who don’t want to be called “Amateurs” either.) The “H..” word was not to be spoken, but only used, like Q code, in CW messages. The ARRL didn’t use the H.. word in any of its early publications, and that may be why its origin is uncertain. Like the RF gain of antenna configurations, this subject became a no-no for early ARRL editors, who avoided it lest they might start a heated debate or insult members. As younger Hams took over the ARRL, the feared legacy of the H…word seems to have diminished. Next month I’ll go over the three most probable origins of the word HAM. W2ILP (I Like Pastrami) Page 2

instead of a regular meeting. As we have done in the past, we’ll meet at the

I have mentioned that we have to move the 745 repeater from where it is on Plant 14 because the E2C people need to get that space back. They loaned us shack space, and tower space, and need to use it now. So I spoke to Public Affairs here, and they contacted the Sector Management to get the ball moving. I was since contacted by a Facilities Manager. I filled him in on the requirements, specifically the altitude we need. But, from what I’m hearing, he might not want to go out of his way to put up any towers. So we might get plopped on top on Plant 25, at a lower height than we are at now. We are supposed to have a meeting soon to discuss this. I don’t have a good feeling on this one, so wish me luck.
Also, we are no longer having Club meetings at U.L. Bill (N2SFT) has retired from there, and we don’t have a person inside that can get us in. Starting in January, we’ll be meeting at our usual time in Ellsworth Allen Park in Farmingdale. It’s just south of Rte 109. See our website for directions and a map.
I’m still working on emptying my house in preparation to putting it on the market in early Spring 2007. We have been going through closets, cleaning them out one at a time. I seem to have collected a ton of “projects” over the years, and I have come to realize that I will never work on them again. So, into the trash they go. My house is a lot emptier now than it was last year. But, there are always some things of value that I don’t want to part with. They get wrapped, and placed in boxes, and those boxes get labeled. Hopefully, when I am retired, I will find time to work on them. My yard has a few things that need to be disposed of before I call the moving truck. I have two or three really good HF beam antennas there. Right now there is a TH3 and a TH6 looking for a home. The TH6 is an exceptional, high gain beam that works really great. And I really don’t want much for these guys, so make me an offer. Also, I expect that the antennas at NN2C’s house will become available soon. He has a Force12 on a rooftop tripod. This is a really good setup for anyone who can’t put up a tower, but would like a good HF antenna as the sunspot cycle starts increasing and the bands load up with good DX. Let me know if you are interested in any of this. It’s time for me to get rid of it.

e-mail address is: email@example.com It is a good idea to get on his e-mailing list, as he is constantly updating his software. He uses the handle “whitehat” for e-mail. Anyway this is what he sent to me as recently as March 21, 2005.
This is software for printing your own QSL cards, matching envelopes, and also a very complete logging program. I first downloaded and tried the software last year and it worked fine, even on my old computer. I don’t know how he keeps finding reasons to update improvements but I will now copy his last e-mail information here:-
I recompiled the envelope program and uploaded it. I downloaded it and it’s OK.
I also made a slight change in the cardmaker program and uploaded it. Works fine.

FUZZY LOGIC? By w2ilp (Imprecise
There has been a great deal of misunderstanding about the term “fuzzy logic” and this has led to many engineers calling various systems fuzzy systems that are not fuzzy and to jokes about the very definition of fuzzy logic being fuzzy. The truth is that most old engineers never learned about fuzzy logic in college. Some learned about it from an article in “The IEEE Spectrum”, which they did not read completely and thus they had only fuzzy ideas about what can be technically defined as a fuzzy system, and what can not. All they learned from the article was that Lotfi Zedah of UC at Berkley had defined something that was supposed to be fuzzy, and from then on anything that they were not so sure about became grandfathered (Zedah means grandfather) into the domain of fuzziness. You can search the web for FUZZY LOGIC and learn about it but I will try to explain it here as simply as possible, without taking more than the space left in this newsletter to do so.
there were digital computers, lots of systems worked entirely using analog
devices. A usual part of analog control
systems was what were called follow up feedback servos. This was basically a servo motor which
mechanically drove a potentiometer or resolver and sometimes other rotating
devices. A driven rotating device
potentiometer or resolver would feed back a DC voltage or an AC voltage and AC
phase which was compared to a DC or AC voltage and/or phase. The servo motor would run until the output
device nulled out, which means it achieved close to zero voltage and/or phase
difference. The original voltages could
come from sensors or be computed by analog operational amplifiers, which could
perform various arithmetic and error rate computations by scaling
voltages. And that is basically how
analog computers operated. Now we use digital computers for the guts of most
computer systems rather than analog operational amplifiers and the programmers
get involved in developing software for the computers to drive industrial machinery
or whatever the analog systems used to drive.
Computers work with Boolean Logic and they use digital numbers, just
like calculators do. Microprocessors
allow computers to perform with higher speeds and more flexibility than the
analog hardware could achieve, but also must be told what to do by software
that must be well designed to do even simple tasks in real time steps. The trouble is that the digital resolution
may be far too precise for what is practically required if we program absolute
numerical values into it. Thus Zedah
concluded that we need to define a set of logic commands that would not make
the computations so nit picking that a practical real time solution could not
be achieved in a practical real time.
This was already being done in both analog and digital systems, but
Zedah defined it in program command terms by recognizing “If” and “If not”
logic commands to replace absolute numerical commands. The truth is that your old mechanical bread
toaster is a fuzzy system, simply because it senses the thermal conditions and
pops the bread out when the condition you want it to pop the bread out is
satisfied. The bread toaster was not
told exactly when numerically or at exactly what numeric temperature to pop the
bread out, so it could be called a fuzzy system. Now I got into a big debate with some
“experts” who called the Hellschreiber mode a fuzzy system. Hellschreiber is a digital mode that produces
typed characters on a computer monitor screen.
It was originally used in
The characters are made up of black pixels, which are simply the same as CW dots and dashes, only sent a lot faster. An asynchronous scan puts them into a 7 by 7 matrix. When the characters appear on the screen in a high noise background level they appear “fuzzy”, but this does not make Hellschreiber a fuzzy system. It is true that human word recognition can help to read message words in noise that the computer might not be able to decode to an ASCII font itself, but still that is not any reason to claim that a fuzzy logic loop is involved, unless we think about the recognition loop that may exist in the human brain itself. In my opinion the brain is not a part of the system because it is intrinsic to human sensory functions that use many factors in recognition that couldn’t even be defined by Marvin Minsky (author of “Society of the Mind”). Fuzzy logic depends on an overall feedback control scheme. There is no real time feedback involved with Hellschreiber. The sending station can not know in real time if any hams receiving its CQ message can read it. The sending station can do nothing to alter its signal in real time to help the receiving ham or hams to be better able to read the signal once it has been transmitted. There is no control loop. As far as the communications system itself goes there is nothing fuzzily logical about it. If the human mind is a fuzzy system then everything we see or sense is fuzzy and the entire world is fuzzy. How can we call everything our brain senses “fuzzy” “if” we can’t logically define anything our brain senses that is “not fuzzy”? This is indeed a paradox. Thus I have to limit my definition to Zedah’s definition of fuzzy logic, which only works if “If” and “If not” are logical possibilities. If you agree with this definition it is not fuzzy. If you don’t agree with it, it is not fuzzy…but if you aren’t sure at this time it might be fuzzy for you.. Nah…It is too late now for me to respond to any feedback from the readers of this or to wake up anyone who fell asleep while reading it. “CQ de WA2LQO”, like all newsletters, is an open loop system. Your response (if any) is too late.

I will continue to write about communications systems here. The simplest system for the radio communication of messages is Morse Code.
The Morse system, originally used on land lines was quite different than the CW system which Hams learned to use and love on radio bands. The original system used a simple electromagnetic clicker as a receiver. It produced a click sound when a DC voltage was applied and another click sound when the voltage was removed. The original Morse Code (later known as the Continental Code or American Code) differed somewhat from the radio Morse Code (known as the International Morse Code). Some of the letters were different in the original code and some of them depended on spacing that differed from the spacing of dots and dashes in the radio Morse. Land line telegraphers were highly skilled in order to read the clicking code. Originally S.F.B. Morse did not think it could be read by humans and planned to have it punch paper tape. Humans took on the challenge of being better than the tape devices at copying weak clicks and schools for the click readers arose. It is interesting to know that some the original land line telegraphers were still alive when I first was interested in being an SWL and a ham. The FCC made sending clicking codes illegal on most ham bands. But the clickers still wanted to use their click copying skills. They were allowed by FCC regulations to do so only on the 11 Meter ham band. The 11 Meter band was known as the garbage band because there was diathermy, model control, and other odds and ends permitted on it, as well as hams with strange modes, before it became the channelized Citizen’s Band. I guess all of the clicking Hams are sk by now. I wonder if all of the CW toners will someday also be silent?. w2ilp
