- The following is a QST
-
- The United States Supreme Court rules that complaints about
- indecent broadcasts can't be pursued past the FCC, AMSAT says no
- to the NTIA and a ham is knighted. Find out why on Newsline
- report number 877 coming your way right now!
-
- (*****
- SUPREME COURT SAYS NO TO LISTENER COMPLAINTS
-
- The Supreme Court has let stand a ruling that bars members of
- the public who are upset over what they feel are legally indecent
- broadcasts from asking federal courts to revive complaints that
- the FCC has dismissed. This by refusing, without comment, to
- review a ruling that says listeners generally don't have the
- proper legal standing to pursue such complaints beyond the Federal
- Communications Commission. The decision not to act could make it
- very difficult to take potty-mouth hams off the air.
- The case involves a complaint filed before the FCC by Peter
- Branton of Chattanooga, Tennessee. Branton filed his complaint
- after listening to a National Public Radio news program on radio
- station WSMC-FM the evening of Feb. 28, 1989. He claimed that
- the program contained a report on reputed New York mobster John
- Gotti, and that it included a tape-recorded telephone conversation
- between Gotti and an associate that was used as trial evidence.
- Branton says that he was offended by the language. He filed a
- complaint with the FCC's Mass Media Bureau, requesting commission
- sanctions against NPR. But the commission refused his demand. It
- ruled that the report was part of a bona fide news story being
- reported nationwide. So the Chattanooga resident then sought help
- from the U.S. Circuit Court of Appeals for the District of
- Columbia but that three-judge panel of that court dismissed
- Branton's appeal last June. In fact, that court went so far as to
- say that Branton actually lacked the legal standing to file it.
- Branton then went to the United States Supreme Court.
- Ironically, his appeal was supported in a friend-of-the-court
- brief submitted by two advocacy groups, People for the American
- Way and the Washington Area Citizens Coalition Interested in
- Viewers' Constitutional Rights. The brief was an unusual one,
- because the advocacy groups said they oppose Branton "on the
- merits of his indecency complaint."
- But lawyers for NPR and other broadcast organizations that
- intervened in the case urged the justices to reject Branton's
- appeal. This is exactly what they did in turning away the Branton
- appeal.
- What does this mean for ham radio? The FCC does not always
- act on complaints about the operations of potty mouth hams. In
- the past, if the problem was truly bad enough the Amateur Radio
- community would seek alternatives including taking the matter to
- other government agencies or approaching congressional leaders for
- intervention to the FCC. That road may no longer be open since
- the Supreme Court feels that the average person is not legally
- astute in determining what is and is not legally indecent.

- AMSAT COMMENTS TO NTIA
-
- In comments filed with the National Telecommunications and
- Information Administration in response to the agency's Preliminary
- Spectrum Reallocation Report, AMSAT-North America has asked for
- wider amateur and amateur-satellite service bands at 13 cm. The
- NTIA's Preliminary Report, published in February, proposed to cut
- U.S. amateur 13 cm allocations in half, from the present 2300-2310
- and 2390-2450 MHz to 2400-2402 and 2417-2450 MHz.
- AMSAT has instead proposed a primary allocation of 2400-2410
- MHz to be shared by the amateur and amateur-satellite services, in
- addition to the 2417-2450 MHz proposed by NTIA. In support of
- this request, AMSAT cited the likelihood of greatly increased
- demand for amateur satellite operations in the 13 cm band in
- coming years, far more than can be accommodated within 2400-2402
- MHz. It also noted the unsuitability of 2417-2450 MHz for
- amateur satellite downlinks because of interference from such
- devices as microwave ovens and the need to coordinate
- amateur-satellite allocations internationally so that they
- are available on a global basis.
- AMSAT has also proposed that a narrow band of 1-2 MHz,
- somewhere between 2300 and 2400 MHz. This to be allocated to the
- amateur service to accommodate the experimental weak-signal tropo
- and EME work now carried out around 2304 MHz. Under NTIA's
- proposal, this would be displaced.
- The NTIA's Preliminary Spectrum Reallocation Report was
- prepared pursuant to Title VI of the Omnibus Budget Reconciliation
- Act of 1993. The same act also requires that comments from
- interested parties such as AMSAT be reviewed by FCC and NTIA
- before any final decision is taken.

- FCC DENIES MORE RULES CHANGE REQUESTS
-
- The FCC has denied two petitions for reconsideration that
- sought a broader definition of permissible communications by
- amateurs. The petitions by David Popkin, W2CC, and Rolland D.
- Cummings, WA0EDA, sought expansion of FCC rules changes that went
- into effect in September 1993, in Personal Radio Docket 92-136.
- The two petitions sought permission for amateurs to retransmit
- certain US government broadcasts, such as time signals. Popkin's
- petition also sought a wording change to the new rules, from
- ''classroom instruction'' to ''instructional activity.''
- These new rules which were the result of an ambitious rewrite
- of Section 97.113. These changes gave amateurs greater
- flexibility in providing noncommercial communications for public
- events and permitted paid teachers to use Amateur Radio in their
- classrooms. They also allow such personal communications such as
- making appointments and ordering pizza over an autopatch.
- In denying the requests the FCC said that the ideas expressed
- in the petitions already had been aired and considered during the
- public comment period for PR Docket 92-136.
-
- (*****
- THE REASON WHY
-
- The FCC is with more and more regularity turning down what it
- seems to view as pointless and mundane technicalities in rules
- changes. It says that a goodly number are filed for no purpose
- other than trying to solve a dispute that has arisen between one
- or two hams. This the Commission says is something that the FCC
- is not about to do. At the recent Dayton Hamvention the FCC's
- John B. Johnston, W3BE explained why minor rules changes are
- becoming harder:
-
- "One approach that we try very hard to use is to avoid what we
- call 'How to' rules. These are rules that specify just how you
- are to do something. And you ask for a lot of 'How to' rules.
- But they seem to always make for problems sooner or later. When
- you have a 'How to' rule your probably trying to solve a problem
- with an existing system. Sooner or later that system is going to
- become passe. But rules seem to have a habit of taking on a life
- of their own and get in the way of new systems." John B.
- Johnston, W3BE.
-
- As far as mundane and non essential changes are concerned, the
- FCC is not going to get involved. They say its a waste your time
- and theirs. And that more than explains why the Popkin and
- Cummings rule change requests were unceremoniously turned away.

- AMATEUR RADIO TO ASSIST OAKLAND CA DURING EMERGENCIES
-
- The City of Oakland California and the Oakland Fire Department
- have entered into a partnership with the Oakland Amateur Radio
- Emergency Services Organization. The Oakland City Council has
- voted a resolution which directs the City Manager to enter into a
- letter of understanding with the Oakland Amateur Radio Emergency
- Service and designate them as a Radio Amateur Emergency Civil
- Emergency Service during any locally declared disaster.
- Members of Oakland ARES will respond to the City's Emergency
- operation Center following any disaster or emergency which may
- threaten life and property in Oakland. They will then disburse to
- assist with the communication needs of emergency operations
- throughout the city.
- The Oakland City Council says that Amateur Radio Operators
- have always been recognized by Oakland as being an effective means
- of providing critical back up communication links during
- emergencies. They note that Amateur Radio Operators have been on
- the scene of virtually every recent major disaster whether in the
- United States or abroad, in some cases they provided the only
- communication with the outside world.

- (*****
- Long Island NY Tower Case Update
-
- Mark Nadell, NK2T says that he has received a favorable
- decision by the New York State Supreme Court in his antenna battle
- with the Town of Hempstead Long Island, but the victory will
- probably be short lived. This is because Hempstead has filed a
- motion to re-argue the case. The motion was filed on the May 10th
- and that forced NK2T to file a cross motion to re-argue his side.
- Nadell believes that Hempstead will probably get a
- clarification of the original finding. This was a court decision
- that annulled the towns order for him to take down his tower and
- antenna.
- If a clarification is granted then Hempstead will almost
- assuredly file a formal appeal. As such, the case could go on for
- years, possibly ending up in the United States Supreme Court if
- both sides decide to wage the legal battle to its ultimate end.
-
- (*****
- 20,000 REPEATERS
-
- On a brighter note, can you believe that there are now over
- twenty thousand FM coordinated repeaters, packet bulletin boards
- and propagation beacons on the air in the United States? Well
- those are the numbers contained in the new edition of the ARRL
- Repeater Directory that made its debut at the Dayton HamVention
- four weeks ago.
- 1994-95 edition of the ARRL directory has been reorganized for
- easier use on the run. The Leagues says that this makes it easier
- to find the listings of the coordinated and registered FM relay
- devices nationwide. The new directory does not contain an
- estimated 5000 to 10,000 more uncoordinated repeaters and unlisted
- packet BBS that are also believed to exist.

- FOUR HAMS JOIN CQ HALL OF FAME
-
- CQ magazine has inducted four amateurs into its halls of fame.
- Joining the CQ Contest Hall of Fame is John Thompson, W1BIH also
- known a PJ9JT; Atilano de Oms, PY5EG; and the late Herb Becker,
- W6QD.
- Thompson, 79 and licensed since 1930, is well-known as both a
- DXer and contester. For more than 20 years he has operated from
- his winter home on Curacao in the Netherlands Antilles.
- De Oms is credited with encouraging contest operations all
- over South America, is an active contester, and has one of the
- most potent stations on the continent. He also is at the top of
- both the Mixed and Phone DXCC Honor Rolls.
- Herb Becker, W6QD, was one of the handful of DX and contest
- operators who conceived, in the late 1940s, the idea of the CQ
- Worldwide DX Contests. The basic rules he helped write more than
- 40 years ago have remained essentially unchanged.
- Charlie Mellen, W1FH, is this years loan entry into he CQ DX
- Hall of Fame. A DXCC member before World War 2, he started over
- in 1945, climbed to the top of the DXCC ladder, and stayed there
- through most of his career.
- The ceremony inducting the four took place at the recent
- Hamvention in Dayton, Ohio.

- DX - SAINT PAUL ISLAND

- In DX, word that Saint Paul Island with operators KW2P, WA4DAN,
- AA4VK, N0TG and possibly W0RJU plan to be active for the first

- 1992 and 1993. Landing permission and transportation for Saint
- Paul has already been received.

- SCOTTISH DISTRESS
-
- Did you hear a strange signal on 14.001 MHz which sounded like
- a distress signal? GM3YEH did. He says that It appeared in
- Scotland on the 2nd of April around 14:00 UTC.
- The Scottish Coast Guard Rescue service in Greenock were
- alerted. In short order they reported back that it is not a
- distress signal but faulty equipment being tested in Florida.
- They would not elaborate further or indicate who the transmitter
- belonged to. But they did indicated that it could take a while
- for engineers to get the signal off the air.

- PLUMBING
-
- Our heartiest congratulations to Andy Watts, G4VIW, on being
- named as a "Member of the British Empire" in the 1994 New Years
- Honors List.
- We have been told that being named as a Member of the British
- Empire is akin to knighthood. Andy, who is Chief Executive and
- Secretary of the Institute of Plumbing in Hornchurch Essex was in
- effect knighted for his -- and we quote-- his "Services to
- Plumbing."
- And no this is not a joke. The honor is for real. The
- British do things in a slightly more formal way then we do here in
- their former colonies.

- Side Note from Steve: It is not unusual for a plumber to be made a Member
- Of The British Empire. The first plumber was appointed by Queen Victoria
- to put in the sewers and water supply system in London. His company also
- manufactured and installed most of the bathrooms a hundred years ago.
- During World War I, American dough-boys stationed or passing through London
- were forbidden to openly gamble. However, that didn't stop them from
- shooting dice in a place where they would not be interrupted, the "loo".
- The royal plumber's name was Thomas Crapper. And so now you know how a
- game of dice, and something else we are all familiar with, became known as
- "craps". -Steve

- ** MROP, GROL and GMDSS exams in Cambridge MA ** Sat. June 18th 1994 **
-
- ** LAST CHANCE BEFORE THE NEW REGULATORY FEE IS ADDED IN JULY
-
- The MIT Radio Exam Team will conduct exams for the General
- Radiotelephone Operators License, the Marine Radio Operators
- Permit and the Global Marine Distress and Safety Systems
- Licenses. The exams will be held at 10AM on Saturday
- June 18th in Cambridge MA at 77 Mass Ave in MIT Room 1-150.
-
- A regular schedule of exams is planned for Cambridge MA on the
- second Saturday of odd numbered months. For more information call
- Nick at 617 253 3776 (9-5).
-
- There is a $35 examination fee. Bring the ** original ** and a
- copy of any commercial license or proof of passing certificates
- you want to claim credit for. Also bring 2 forms of picture
- ID, a black pen and a pencil.
-
- ** If you are thinking of getting a commercial licence
- now may be the time. The FCC is talking about imposing
- an additional "regulatory fee" after July 1. This will
- probably be $105 - ouch- for GROL applicants. Since
- the GROL is a lifetime license getting it now avoids
- the fee.
-
- This exam session is timed to allow all the paper work to reach
- the FCC before July to avoid the proposed "Regulatory fee"
-
- Copies of the question pools are available from the
- Government Printing office or from W5YI at 1 800 669 9594.
- This is probably the best study guide available for the
- moment. A few copies are available for pickup in Cambridge.
-
- The General Radio Telephone Operators License is required to
- service transmitters in the aviation, maritime and international
- radio services. A Maritime Radio Operators Permit is required to
- operate radiotelephone stations aboard large ships and certain
- aviation and coast stations. Large ocean going ships will be
- required to carry Global Maritime Distress and Safety Systems
- licensees. A GMDSS Maintainer License is required to service
- GMDSS equipment.
-
- The Global Maritime Distress and Safety Systems Operator
- (GMDSS-O) licenses exam question pool is scheduled for release
- shortly. Exams for this license will be offered if the necessary
- material reaches us in time.
-
- At a later date exams will be available for the Commercial Radio
- Telegraph operators licenses. Amateur Extra Class operators may
- be particularly interested in obtaining a commercial telegraph
- license as they will receive credit for the 20 WPM 2nd class code
- exam.
-
- The MIT Radio Exam Team operates under the auspices of the
- National Radio Examiners COLEM, part of the W5YI group.

- Um, 200ppm pretty much wants more than a simple varicap to make it happy. Even
- with carefully selected (and spurious de-Q-ed inductors) past 200ppm it is
- remarkably easy to get into odd spurious oscillations due to crystal spurs. As

- Hi Jim,
-
- Don't coordinators do this anyway? If "Applicant A" applied for a pair 2
- months before "Applicant B", yet the second applicant's station location
- provides better spectrum use and no interference, who should the
- coordinator give the available frequencies to?
-
- I also think that if "Scrubba" made it a policy that 75% of all repeater
- coordinations were to be for "open" repeaters, as long as that policy was
- equally enforced, they'd be safe.
-
- Yes, they might get sued. You might get sued. You might sue me. The
- real threat of getting sued should not drive decisions. The threat of
- losing should.
