**  What do all those "tones" mean?
	Sub-Audible Tone:  A low tone that you're not supposed to be able to
	hear.  It's used as a "PL Tone."  PL is "Private Line", a trademark
	of Motorola for their implementation of CTCSS (Continuous Tone Coded
	Squelch System).  Basically, the transmitter sends the signal with
	the Sub-Audible tone and the receiver only opens when it hears signals
	with that tone.  Signals without the proper tone are ignored.  This
	is useful for "closed" repeaters, or for repeaters on the same 
	frequency that have overlapping geographic areas.
	Tone encode refers to the feature of providing the tone on transmit.
	Tone decode refers to the feature of responding to the tone on receive.
	Tone squelch refers to all of the above.  DTMF refers to Dual Tone 
	Multi-Frequency, or "Touch Tone" which is a trademark of AT&T.  DTSS
	probably means Dual Tone Squelch System and refers to the feature of
	providing a predefined sequence of Touch Tone digits to open the
	repeater for transmit.  DTSS is an alternate method from CTCSS, which
	provides a way to use a "closed" repeater even if your radio doesn't
	do Sub-Audible Tones.

**  Where can I learn more about Amateur Radio if I live outside the US?
	Write to the ARRL and ask.  They can usually tell you how to get a
	license in your country.

	If you know of any location where this information is available
	electronically, whether by an e-mail server, anonymous FTP, or a
	contact person, please mail it to us so we can include it here.  Send
	it to hamradio-faq@uts.amdahl.com.

**  How can I get a "reciprocal license" if I am a licensed ham from another
**  country or if I am a FCC licensed ham who wants to operate in another 
**  country (on vacation)?
	You need to submit a FCC Form 610-A to the FCC, PO Box 1020, 
	Gettysburg, PA 17326.  They will then send you a reciprocal permit 
	for alien amateur licensee (FCC Form 610-AL).  You must be a citizen 
	of a country with which the United States has arrangements to grant 
	reciprocal operating permits to visiting alien Amateur operators.

	For FCC licensed hams operating abroad, the following guidelines
	apply:
	* A reciprocal license is required in all foreign countries (that have
	  a reciprocal operating agreement with the US), except Canada, where
	  the FCC license is automatically valid.
	* Send a SASE to ARRL Regulatory Information Branch, telling them
	  which country you are going to visit and they will send you the
	  info and an application form.  Foreign hams can likewise request
	  information from their national Amateur radio society.
	* Submit your application with a certified copy of your Amateur 
	  license (ie, notarized copy), and fee if applicable (use a bank draft
	  of a bank that does business in that country) to the appropriate 
	  licensing administration of the foreign country.  Processing may
	  take 30 to 90 days.
	* If less than one month, you could try sending the application and
	  pick up the permit upon arrival in that country.
	* Most countries will not allow you to bring communications equipment
	  into their country without a license or permit.  If you applied, but
	  haven't received the permit yet, show the copy and your FCC license
	  to the customs officer, however, the equipment may still be held at
	  customs until your departure.
	* Be sure to use only those frequencies covered by your FCC license
	  which are also used in the foreign country, unless otherwise
	  authorized.

**  My apartment or housing complex does not allow outdoor antennas, now what
     do I do?
	First of all, don't despair.  Many hams have similar problems.  Many
	books offer advice for the growing group of hams that cannot put up
	antennas.  Some options are:
	* Install an "invisible" antenna made of magnet wire.
	* Disguise an antenna as a flag pole.
	* Install an antenna in the attic.
	* ASK the apartment manager.  You may find they will let you put up
	  something as long as it "is invisible" or "doesn't disturb your
	  neighbors" or "doesn't attract lightning".
	* Operate primarily from your car.
	* If the restriction is due to local ordinance, you may have relief 
	  via PRB-1.  Meet with the local government and seek an informal
	  compromise.  It is possible to win in court...but it's expensive and
	  time consuming.
	* If you are restricted by "covenants" attached to the deed of your 
	  home, your options are severely limited.  Covenants are considered
	  to be private, voluntary contracts between individuals and are 
	  outside of the intended application of PRB-1.  In many cases, you
	  can petition the Homeowner's Association for an exception.  Sometimes
	  you can win in court on the basis that other violations of the 
	  covenants by others without action taken constitutes abandonment
	  of the agreement.
	* For further information, contact the General Consel's office of the
	  ARRL, 225 Main St, Newington, CT 06111.

**  I got TVI...HELP!!!
	Here's some hints on Television interference, but this is not a
	complete list.  There are also books on the subject available from
	ARRL.
	* If cable TV is an underground feed, look for central distribution 
	  box.  Check for a grounding rod.
	* Try installing torroids on the cable TV cable close to the TV, and
	  maybe torroids on the AC cord as well.
	* VCRs are notorious for RF leakers, try disconnecting the VCR.
	* Check to see if interference is better or worse when cable is
	  disconnected and you use rabbit ears instead.  It could be the
	  cable company's problem!
	* Calling the cable company may get results, since they are also
	  responsible for RF leakage from their equipment.  However, they
	  are very often obstinate.  Good luck!  Try some or all of these
	  suggestions before calling the cable company:
	  1.  Log the interference, noting geographical location, frequency,
	      and characteristics.
	  2.  Bring it to the cable company's attention in writing, preferably
	      addressed to "Chief Engineer", or "Technical Staff".
	  3.  Don't be accusatory, instead ask for assistance in resolving
	      the problem.  Try to work it out with someone technically
	      knowledgeable.
	  4.  Do mention your "licensed radio system", but try not to be too
	      specific about "ham" or "CB" unless requested.
	* Try moving the radio antenna further away from the TV sets.  Make
	  sure the SWR is LOW.

**  Did you know that you can get college credit for being a ham?
	It's true!  You can receive up to 14 credits in electronics and
	engineering thru placement tests for CLEP (College Level Entrance
	Placement) exams and DANTES (Defense Activity for Non-Traditional
	Educational Support) exams if you have an Advanced or Extra class 
	Amateur license.  For more information, ask your campus education 
	office or (for DANTES) your military education office.

**  Can I take my HT on an airplane and operate it if I get the permission
    of the captain?

	Technically, maybe.  But don't count on it.  In general, you can't use
	a radio or scanner on an airline (or charter) *unless* the airline
	allows it and the pilot-in-command (PIC) determines that it will not
	interfere with the instruments and radios on that specific aircraft.
	Very few US airlines allow passengers to use radios so be ready to
	disconnect the antenna when you ask.  (Don't even ask to transmit.)
	For reference (in the US) the pertinent portion of the Federal Aviation
	Regulations (FARs) is Part 91, paragraph 91.21.

	Due to airport security, you may have a little difficulty carrying the
	HT (or any electronic equipment) onto the airplane.  Generally, you 
	can appease the security guards, simply by showing that the unit is 
	operational and doesn't have a bomb inside.  For a radio, just turning
	it on and opening the squelch satisfies them.  Expect more difficulty
	during periods of increased security.

	On a private airplane, it is legal to operate an amateur radio if you
	have the permission of the PIC.  It is still possible for the radio to
	interfere with the plane's navigation or communication equipment, so
	be sure to ask first.  Always obey the requests of the PIC.  He knows
	his airplane and radios better than you do.

**  What is the standard for measuring Morse code speed?

	The word PARIS was chosen as the standard length for CW code speed.
	Each dit counts for one count, each dash counts for three counts, 
	intra-character spacing is one count, inter-character spacing is three
	counts and inter-word spacing is seven counts, so the word PARIS is
	exactly 50 counts:

        PPPPPPPPPPPPP     AAAAA     RRRRRRRRR     IIIII     SSSSSSSSS
	.   -   -   .     .   -     .   -   .     .   .     .   .   .
	1 1 3 1 3 1 1  3  1 1 3  3  1 1 3 1 1  3  1 1 1  3  1 1 1 1 1  7 = 50
          ^                      ^                                     ^
          ^Intra-character       ^Inter-character            Inter-word^

	So 5 words-per-minute = 250 counts-per-minute / 50 counts-per-word or
	one count every 240 milliseconds.  13 words-per-minute is one count
	every ~92.3 milliseconds.   This method of sending code is sometimes
	called "Slow Code", because at 5 wpm it sounds VERY SLOW.  

	The "Farnsworth" method is accomplished by sending the dits and dashes 
	and intra-character spacing at a higher speed, then increasing the 
	inter-character and inter-word spacing to slow the sending speed down 
	to the desired speed.  For example, to send at 5 wpm with 13 wpm 
	characters in Farnsworth method, the dits and intra-character spacing
	would be 92.3 milliseconds, the dash would be 276.9 milliseconds, the
	inter-character spacing would be 1.443 seconds and inter-word spacing 
	would be 3.367 seconds.

** How do I modify my current Amateur license?
	To modify your license (change of address, change of station location,
	change of name, renewal, or even change of callsign), submit an FCC
	Form 610 to the FCC.  Forms are available from the FCC or ARRL or a
	local VE session or ham radio store.  Do NOT use a photocopy.  Check
	off the appropriate boxes, fill in the new/changed information, SIGN
	THE FORM, and attach a copy of your current license (or a brief letter
	of explanation for its absence, ie, "my dog ate it").  NOTE:  If you
	check the box to change your callsign, YOU WILL GET A NEW CALLSIGN,
	even if all you wanted was to supply a new address; if you want to keep
	your callsign, DON'T CHECK THAT BOX.  Send the form to FCC, POB 1020,
	Gettysburg, PA 17326.  Turnaround time (for CURRENT licensees only)
	is about 2-4 weeks.

	ANY ham can apply for a new callsign (this is different from the past
	where you can only get a new callsign if you move or upgrade).  You 
	can't specify WHICH ONE you want, a new one comes from the same pool
	as new licensees for that class of license.  The callsign is based on
	your mailing address.  For overseas military and civilians, be sure to
	specify a station location that is within FCC jurisdiction.

	New licenses are for 10-year terms.  If you apply for renewal before
	its expiration date, the expired license is valid for 60 days after
	expiration to allow for the new license to arrive.  You have up to
	2 years after expiration (5 years for an old 5-year license) to renew
	before re-examination is required (but you can't operate with an 
	expired license).  You will lose your current callsign after 1 year 
	after expiration if you don't renew.

**  I'm confused about XXX, should I ask the FCC?
	Whatever "XXX" is in this case, the overwhelming ARRL and net opinion
	is a resounding "NO!", at least not as a first step.  Amateurs are
	generally very law-abiding people and have historically written the
	FCC asking for clarification on some operating practice or another.
	This is a very dangerous practice, for several reasons.

	Most amateur radio regulations (contained in Part 97) are generally
	very loosely-worded, so as not to restrict experimentation and new
	techniques.  But asking the FCC for a clarification will set in motion
	the process of "clarifying" it for everyone (i.e. new rulemaking.)

	Examples of such restrictive rulings include varying topics like when
	Hams can help non-profit agencies or effectively forcing packet BBS
	sysops to screen messages before forwarding them.  They were the result
	of well-intentioned questions by Hams that forced the FCC to make a
	ruling where they previously allowed the amateur radio community to
	police itself.

	Under all circumstances, it is better to first read the rules yourself.
	Then, if there's a problem, ask your national amateur radio organiza-
	tion (such as the ARRL in the US) which can give qualified advice about
	interpretation of FCC regulations.  Organizations like the ARRL also
	have the influence to ask the FCC informally, without forcing a ruling.

	Even if asking the FCC doesn't result in a restrictive ruling, it is
	generally a good idea to not overburden an under-staffed and under-
	funded government agency with a lot of correspondence.  The Amateur
	Radio Service has traditionally been a low-workload "hands-off"
	service, and has enjoyed a wide latitude from the FCC.  Please don't
	ruin this image for your fellow amateurs.
