Subject: *** R-U-A GENIE Garage Door Opener Guru???.....Talk To Me!!!!..please?
To: [e-mail]

I have had some experience as a commercial two-way radio tech, and as
a result have recently been "suckered" into helping a friend fix his
Genie Garage Door Opener.  If you are at all knowledgable about these
things, could you PLEASE be filled with Christmas Spirit and help
a guy, whos helping another guy???? :-)))
Here are some of the questions I have:
(by the way,....the mech. portion of the door opener is working fine)

*The receiver is a model "AR-75" and also states a freq. of "310"
 Does this mean that the transmitter and receiver operate on 310.000Mhz.,
 or just within this general freq. band???

*This is an older system that uses a plastic "code key" that allows small
 jumpers or fingers to make contact with ground.  How does changing this
 code effect the carrier?  Is the freq. pulse modulated or other?

*What is the best method to align the transmitters with the receiver?
 (I do have access to an FM service monitor, freq. counter, wattmeter, etc.)

ANY help or suggestions you might have would be VERY MUCH APPRECIATED,
and might even get you on my "Christmas List"!!! :-)

Please email "[e-mail]"

Thanks again and Happy Holidays!
Jeff

Subject: Adapting Larsen whip to swivel mount.
To: [e-mail]

  I am trying to find an adapter to connect a Larsen whip to the
3/8"-24 hole on a standard car swivel mount.  Something which has a
3/8"-24 thread on one end and a 0.100" hole with a set screw on the
other would do it.  Even better would be something threaded 3/8"-24
on one end and 5/16"-24 (standard Larsen thread for antenna cones and
springs) on the other.

  I'll probably just make my own adapter in the machine shop, but I'm
amazed that no company seems to manufacture such a device.  Does
anyone know of a source?

It is slightly thicker but not too much.  It also gets a little warmer when
used than the 7.2.  The charger stand that is used for the 7.2 can also be
used for the 12.  At least the one I have can use it and it is just the
standard Alinco charger for the F1JT

Subject: FM stories wanted for QST
To: [e-mail]

As conductor of the FM column in QST magazine, I'm working on a
possible upcoming article about operating VHF/UHF FM from outside
the US. The idea is to let VHF/UHF FM users know what kinds of
things (good and not-so-good) can be expected if, for example,
they bring a hand-held transceiver along on a vacation or business
trip to the Caribbean, Europe, Asia, Australia, etc.

If anyone has had a FIRST-HAND opportunity with operating
VHF/UHF FM outside the continental US, please shoot me a note
about your personal experience. I'd like to hear about obtaining
licensing/operating permission, use of repeaters/simplex, popular
bands/frequencies, unusual operating practices, bringing equipment
into other countries, if social contacts resulted, etc. Perhaps
I'll be able to "anthologize" several people's stories in one
column or in serial form. Depends on the response.

Reminder: I don't like to write the column; it's a forum for *you*!
We want ARRL Members from all over the world to share your thoughts
on Amateur Radio FM operating and technology. We're always looking
for *any* interesting stories, anecdotes, suggestions, comments,
case histories, photographs, opinions, etc, for the FM column...
so send 'em in!

Thanks for your help and happy holidays!

I can't answer for Steve's cabinet, but I can answer at least somewhat for
Bill Burden's.  Bill WB1BRE is the New England Division Director.  Like Steve,
Bill also runs a cabinet meeting a week or two before the Board of Directors
meet.  Bill invites his vice-director, all division appointees, all Section
Managers and their appointees, the Presidents of all ARRL-affiliated clubs
in the division (the clubs may, at their discretion, send someone other than
the club president), and selected others.  He tries to make his agenda known
to these folks beforehand, so that they may solicit input on the discussion
topics.  If there are issues that he wants very wide input on, he sends out
a division newsletter with a questionnaire (and if not enough people respond
to the questionnaire, he sends his cabinet members out to clubs, etc. with
questionnaires).  As president of our radio club, I've attended two of the
NE Division cabinet meetings now, and I can tell you that they are hardly
an "amen chorus"!  There are some very outspoken people in the leadership
of the sections and the division, and believe me, not everyone agrees with
everyone else.

Does Bill listen to his cabinet?  Yes, but he also lets them know what he's
heard from the membership at large, and he incorporates that into his words
and actions as well.

Bill uses the cabinet meeting as a sounding board, as a chance to get to know
the ARRL and club leadership (SMs, appointees) in his division, and as a chance
to educate those leaders about issues involving Amateur Radio, the ARRL, the FCC,
etc.  Each of the cabinet members has his own reasons for attending.

Possibly.  It's also possible we'd get a more divided organization -- consider
how well DXers and Contesters, repeater owners and weak-signal folks, CW fans
and haters, etc. get along now (okay, okay, so I've been reading too much
r.r.a.policy lately! I keep forgetting the Internet isn't a good cross-section
of the amateur world... :-)

I do know that at least some of the directors currently get input on
some of these topics (digital considerations, DX, repeater issues, etc.)
from the ARRL committees whose purpose it is to oversee the particular
area(s) in question.  If I remember correctly, reports from these committees
are given at each Board meeting; I do know that Bill WB1BRE often (always?)
invites the New England representatives of any of these committees to his
cabinet meetings.  My hope is that other division directors would do the same,
though I realize that may only be wishful thinking...

Amen to that!  Volunteerism is not a popular thing these days.  And I suspect
that's why elections aren't held at these levels.  It's tough enough finding
folks to run for Section Manager...  Interesting thought, though.

  Since we're dealing with coherent fields, wouldn't the total field
strength be doubled, giving a quadrupling of the power density?

It's good that you did! When we hams think of digital communications,
we tend to forget that there are other modes, and that there are
reasons for selecting specific protocols. The books don't say much
about this kind of stuff (well, not the ham radio books, anywho).

Yeah, I know. But think about all those solder joints, all done to
consumer-electronics specs...  ...ugh.

Really, the vibration is awful. And the mounts tend to absorb more
shock than vibration.

I'd look to the commercial world, to some simple process-control
computers used for embedded systems (help me out, some of you
control-systems designers!). There are small computers that are
designed for dedicated applications in hostile environments. You
could load up the RAM and then leave the disk drives on the ground,
or even embed control program in non-volatile memory. Considering
that the hard drive is three times the weight of a good-sized
control computer...

Hey, if you insist... ...but (tempt tempt) wouldn't it be interesting
to be recording and processing telemetry on the ground while someone
else flew the airplane? (Hey, Joe, that was a 6G turn!).


In the event of a failed mission (or the unlikely event of a water landing),
you'd have data right up until time of death.

Ah! Here's where knowledge of how R/C aircraft are constructed actually
would help. ALL of them have big access hatches (usually the wing
unbolts) to get at the radio. The charging connections and such
are frequently inside. So could be your serial port.

Again, go for a simple computer that talks, either via a radio
link or via a serial cable, to another, more sophisticated computer.

Bear in mind, when you think about flying it anywhere, that you have
a liability problem. You can't fly R/C, and be insured, except at an
AMA sanctioned field. That means no coverage of news events. Your
altitude is also limited by FAA regs, so you can't foul up air
traffic. By the way, people have been sued for millions after their
airplane whacked someone, so this is not trivial matter.
