- Revision: 1.6 12/26/93 15:45:09
- Changes: Added new index file, Gopher, WWW, and WAIS entries
-
- This administrivia file and the companion Amateur Radio Elmers Resource
- Directory are intended for non-commercial distribution via Usenet. Any
- other uses, please E-mail for permission.
-
- A Brief Historical Overview:
- ++++++++++++++++++++++++++++
-
- If there is any one constant in the changing state of the communications
- art, it is that "Hams" (Amateur Radio Operators) have always been on
- the forefront of it. Rumors abound where the term "Ham" came from.
- Some of the more amusing are described at the end of this article.
-
- Regardless of origin of the name, a "Ham" is universally recognizable as
- one who experiments in radio and communications.
-
- Whether it be constructing a low-power CW radio with vacuum tubes, or
- designing TCP/IP packet networks, such experimentation has historically
- spilled over into the mainstream such as was the case with Edwin
- Armstrong, who developed the regenerative oscillator and FM radio, or
- General Curtis LeMay (W6EZV) who was instrumental in making Single-
- Sideband the communications standard for the Strategic Air Command
- (1947-1992, now reorganized into a joint command called USSTRATCOM) and
- eventually the U.S. Air Force. Although packet-switching techniques
- originated from DARPA (Defense Advanced Research Projects Agency) and
- the ARPANet, no one can deny the tremendous influence that amateurs
- have had in demonstrating the viability of TCP/IP and AX.25
- communications via radio links. The efforts of AMSAT (the Amateur
- Satellite Corporation), including the development of many ham satellites
- and the low-orbiting Microsats (communications satellites no bigger than
- a breadbox that use store-and forward packet techniques), have certainly
- advanced the state-of-the-art in communications, one of the defined
- purposes of the Amateur Radio Service, as recognized by international
- treaty.
-
- Since in many cases hams are writing "the book", there is often no
- "book" or other established reference for a beginner to refer to.
- Traditionally, information has been passed on from ham to ham via word-
- of-mouth. Like many of the traditional crafts, a variation of the
- Master-Apprentice system has emerged, the Elmer-Novice relationship.
- Called "Elmers" because they are usually older and wiser, having the
- benefit of many years in the hobby, including several failed projects,
- and an electric shock or two, they have traditionally been the mainstay
- of amateur radio, and the source of many new hams, particularly those
- interested in working on emerging technologies.
-
- Even more importantly, Elmers provided an outlet for the impatient
- newcomer who wanted "to know everything, and right away." Faced with
- such a request, a good Elmer will smile and proceed to lead the novice
- through some project or operating experience. Several hours, days, or
- weeks later, the novice would have his answers, but would have earned
- them. Even better, the sense of accomplishment would boost the novice's
- confidence and nudge him or her down the road to being a model,
- experienced ham operator.
-
- Many present hams feel that such an experience is missing today. In
- today's hustle-bustle world, the response to such natural curiosity and
- desire to learn is, more often than not, "I'm too busy" or "RTFM." As a
- result, the quality of new hams declines and the knowledge and operating
- habits they develop in their first formative months and years leave much
- to be desired. And the very same hams who claim that they "can't
- understand the new generation" also, in almost the same breath, lament
- about the "decline of amateur radio."
-
- What is an Elmer today?
- +++++++++++++++++++++++
-
- An Elmer today is of any age, male or female, who has some expertise and
- is willing to share it with beginners. Elmers don't even need to be
- licensed amateurs, just people with knowledge in some area of
- electronics or communications technology.
-
- What is a Usenet Elmer?
- +++++++++++++++++++++++
-
- With the ever-widening scope of the Internet, and the amateur radio
- newsgroups on Usenet, the potential for Elmers to share their
- knowledge to a wide audience has never been greater. To that end, I
- have started to maintain a list of such Elmers. Volunteers need only
- send me their name, E-mail address, and area of expertise. I have set
- up an administrivia mailbox for this purpose (elmers-request@
- unomaha.edu, the default Reply-To: of this message).
-
- Those desiring a more extensive list, or who need more specific
- assistance, are encouraged to contact Rosalie White, WA1STO, Educational
- Services Manager at the American Radio Relay League, 225 Main St.,
- Newington, CT 06111 or via electronic mail addressed to
- rwhite@arrl.org.
-
- How may I obtain the latest copy of the Elmers List?
- ++++++++++++++++++++++++++++++++++++++++++++++++++++
-
- There are currently 7 ways of obtaining the Elmers List. Any site
- at least reachable by Internet E-mail can use options 3 or 4:
-
- 1. Usenet News: The latest copy of the list can be found in the
- companion posting to this message, "Amateur Radio: Elmers Resource
- Directory." Since the list is cross-posted to rec.radio.amateur.misc,
- rec.radio.info, rec.answers, and news.answers on the 1st of each month,
- with an expiration date 6 weeks into the future, there should always be
- a copy available at most news sites. Check your newsreader
- documentation for information about reading previously-read articles.
-
- 2. Anonymous FTP: If your site is directly connected to the Internet,
- you may retrieve the latest copy via File Transfer Protocol (FTP) from
- the following sites:
-
- ftp.cs.buffalo.edu /pub/ham-radio/elmers*
- rtfm.mit.edu /pub/usenet/news.answers/radio/ham-radio/elmers/*
-
- 3. Mailing-List: Since the list is cross-posted to rec.radio.info, the
- latest copy may be obtained from the mailing-list gateway for that
- newsgroup (along with many other informational articles about radio)
- when it is published each month. To subscribe, send E-mail to:
-
- listserv@ucsd.edu
-
- and in the BODY (not the Subject) of the message, write:
-
- subscribe radio-info
-
- The server may not be able to determine your return address. In that
- case write:
-
- subscribe radio-info (your E-mail address)
-
- You should get an acknowledgement very shortly.
-
- 4. Mail-Server: If you don't want to read through the entire gateway
- of rec.radio.info, or want a copy of the list right away, send E-mail
- to:
-
- mail-server@rtfm.mit.edu
-
- and in the BODY (not the Subject) of the message, write:
-
- send usenet/news.answers/radio/ham-radio/elmers/admin
- send usenet/news.answers/radio/ham-radio/elmers/index
- send usenet/news.answers/radio/ham-radio/elmers/list
- send usenet/news.answers/radio/ham-radio/elmers/diff
-
- and the latest copy of the list should be sent to you E-mail within 24
- hours (the mail-server uses batch priority to reduce system demand).
-
- The last three services are experimental. I'm not terribly familiar
- with them, and cannot offer much technical support regarding their use.
- (I'd appreciate feedback on whether or not you find them useful,
- though.)
-
- 5. Internet Gopher: The latest copy of the list should be available
- from the following Gopher sites, all at standard port 70:
-
- cc1.kuleuven.ac.be
- jupiter.sun.csd.unb.ca
- gopher.univ-lyon1.fr
- ftp.win.tue.nl
- gopher.win.tue.nl
-
- see also comp.infosystems.gopher
-
- 6. World-Wide Web (WWW): The latest copy of the list should be available
- from the following WWW site:
-
- URL: http://www.cis.ohio-state.edu:80/hypertext/faq/usenet
-
- under pages:
-
- radio/ham-radio/elmers/admin
- radio/ham-radio/elmers/index
- radio/ham-radio/elmers/list
- radio/ham-radio/elmers/diff
-
- see also comp.infosystems.www
-
- 7. Wide-Area Information Service (WAIS): The latest copy of the list
- should be available from the WAIS server at rtfm.mit.edu (standard port
- 210) in database "usenet."
-
- see also comp.infosystems.wais
-

- * Possible origins of the word HAM:
-
- The acronym "Home Amateur Mechanic" or...
-
- from the Cockney pronunciation of "L'amateur" or...
-
- the initials of the founder of the American Radio Relay League, Hiram
- Maxim, W1AW (his actual middle name being Percy apparently
- notwithstanding) or...
-
- from the call letters of one of the first amateur stations at Harvard,
- H.A.M. (please, no flames from W1XM at MIT)
-
- Dale Mosby, N7PEX, offers the explanation that HAM must stand for "Hardly
- Any Money," considering the investment one could make in the hobby.
-
- Knowledgeable individuals from the American Radio Relay League (ARRL),
- and other radio historians, seem to agree that the terms "Ham" and "Lid"
- (an inept operator) both originated with landline telegraphy. A "Ham"
- was a show-off and a "Lid" was a telegraph operator so inexperienced, he
- had to use a pot or can lid to rest his telegraph sounder on to properly
- copy the code.
-
- As an interesting historical footnote, early telegraph operators may
- have been the first to experience the infamous curse of our
- communications age, Repetitive Stress (or "Carpal Tunnel") Syndrome
- (called "Glass Arm" in those days, which encouraged the invention of the
- semi-automatic or "bug" key).
-
- (Larry E. McDonald, N6ZMB, wrote to point out another plausible origin,
- which doesn't necessarily contradict the ARRL version. The term "ham"
- may have been derived from "ham-fisted" or "ham-handed" to describe poor
- telegraph operators who were hired from the ranks of radio operators.
- Or maybe "ham-fisted" and "ham-handed" are derived from "ham." Who
- knows?)

-
- Yes, indeed, it does cause a noticeable degradation in audio quality.
- In the case of units like the 2010 which are primarily going to be used
- to listen to commercial broadcasters, there is a good bit of benefit in
- having a detector that can correlate both sidebands, though admittedly
- for ham work, it's much less of a requirement.
-
- But it basically comes down to how much audio degradation you mind. If
- I am listening to a commercial shortwave broadcaster, I expect much higher
- fidelity than I do from amateur SSB transmission. With SSB, I just want
- to be able to make out the words. (On the other hand, I expect a lot
