 The Houston Amateur Radio Helpline, a telephone, touch-tone activated
 service for Amateur Radio operators in the Houston area is back on line
 again after a major hard drive crash.

 This service is over 2 years old, receives around 700 calls per month.
 We try to keep up to date with all the VE sessions, clubs, club activities,
 special FCC and ARRL happenings, Classes,etc.

 If you are in the Houston Texas area please give it a call. If you have
 information which needs to be posted please use the 04 option from the
 main menu to leave the information in 'your' voice. We need input as well
 as people using the output :)

I used a glass-mount antenna for a while and was extrememly unhappy with its
performance.  If your friend can't bring himself to get out the drill, you
might suggest he try a trunk lip mount and snake the cables into the cab
though the back seat.

And if his concern about drilling a hole for a proper roof mount is resale
value, remind him that he can advertise the car as "cellular-ready."  ;-)

Be forewarned that learning the code as visual of dots and dashes is not a
particularly good idea, as it introduces an additional level of translation
(aural to visual) that you will probably find puts an upper limit on the speed
at which you will be able to copy.  Ideally, you want to "hear" the
characters, not "see" them in your head.

You would probably be better off visiting your local purveyor of ham goodies
and investing in a cassette training course, or using a computer-based
trainer.  A good FTP site for the latter is "ucsd.edu" under "pub/hamradio"
(if I'm not mistaken.)  SuperMorse for DOS is dandy (look for "sm###" where
"###' is a version number), and I'm sure you'll find some UNIX-based software
there as well if that's better suited to your environment.

So, rather than warning one another off constantly, though I guess it's
good to know what you're in for, how do we encourage Ramsey to continue
taking steps in the right direction, rather than driving them from the
business?

Heath is gone, and with it THE major source of economical amateur
radio gear, and 'on the job' training.

I've seen some of the first of the Heath ham gear, and it was probably
in the category of 'not too good,' too. They were selling oscillator-only
transmitters when such things were kind of marginal as state-of-the-art.
And I'll bet their manuals didn't start out perfect.

Goodness knows Knight-Kit had its problems, though they went to school
pretty well on Heath. Eico didn't go to school as well, and produced
some real losers, along with a few winners.

And some people don't realize that that mainstay of 1950's and 1960's
ham hear, E.F. Johnson, produced some of their more basic gear in kit
form. If we'd known that buying them would have ensured us easy access
to transimitting variables for life, we probably would have made the
investment :-)

Anyway, I'm glad Ramsay and some of the others are around. But since
they're really start-ups, they're going to have problems. The question
is, how do we help them improve?

...or buy a kit of parts for one of those same projects from a
supplier of parts who expects you to work from the construction
article.

Personally, the part I *hate* is collecting the parts. After all,
in single-unit quantities they get to be expensive. Not to mention
the time and gas expended. 'Twas easier when I lived in silicone
valley, because I could get most things at Halted, two minutes from
work. (They also have Ramsey kits at discount prices, BTW)

Certain simple projects, like power-supplies, can be built from
Radio Shlock stock. But not many things.

These mini-suppliers seem to be the ARRL's answer to the complaint
voiced by many a dozen or so years ago that the QST projects were
fine if you had the ARRL Hq. lab's junk-box at your disposal. They
amount to a 'group buy,' with a little fee for the trouble of the
guy who puts it all in a bag.

The one that always tickles me is crystal controlled QRP transmiters.
They're usually designed and written by guys who must have a whole
box of surplus crystals. Buying crystals is now very expensive, and
the quality can be real iffy. VXO rigs are a bit better, but a
decent, basic, VFO is an experimenter's friend.

BTW, I believe that Doug DeMaw is a saint, as is Lew McCoy. These
folks, from the days of the 'Novice Transmitter Using Parts Gleaned
from Two Dead TV Sets' to the days of 'Tuna-Tin Two,' have always
shown what can be done with making lots of fun out of little money.
Another deity has to be Wes Hayward.

Their are a couple of heirs apparent, but they haven't come into
their own, just yet.

By the way (ARRL, are you listening), guys like these probably have
done more to increase the ranks of membership than all of the Civics
Book rhetoric about representation combined.

Subject: RF Site/Region Modelling
To: [e-mail]

Hello there folks. I am looking for information, pointers, etc.
on doing some terrain analysis with respect to radio signal (RF)
coverage modeling.  I know that commercial consultants to broadcast
outfits use something along those lines, but (A) I've never really done
any serious elevation-dataset work, (B) I'm an ham who works with GIS,
(C) I can't afford the commercial rates for site modeling, and (D) I
have the data in hand in terms of ham radio repeater site locations, i.e.,
antenna height, effective radiated power, and the USGS Digital Elevation Maps
from resdgs1.er.usgs.gov for my area of interest (State of Tennessee, USA).
I am seeking any experiences from those of you who might have worked with
this application.  I have access to GRASS 4.1 and AGIS/MAPIX GIS packages
for full treatment of DEMs, site modelling, etc. so that might suffice
rather than recommending I go buy a multi-hundred$ analysis package, or
paying similar consultant fees.

Doing RF modeling is not exactly on a line-of-sight basis, although
that's a good base to work out from in the beginning.  Depending on
frequency there's a bit of bending that would influence signals in
valleys, etc.  I plan on investigating those factors carefully from
other references.  We are planning a packet-radio network that would
eventually span our state for message passing, hobby traffic, etc. and
good site planning is essential to our effort.  Funding is out of our
back pockets which have more change than greenback, but there is a
wealth of raw materials out there (DEMs, GIS software, site info) which
give us a healthy start and will allow us to plan wisely.  My lack of
personal experience in 3-D modeling leaves me with knowledge gaps on how
best to proceed.

Your input is appreciated; I would prefer responses directly to my mail
address ([e-mail]); if desired by anyone I can easily repost
a summary of responses.  Yes, I've cross-posted this to relevant groups
in the GIS world, so apologies for its verbosity on basic stuff.  PS,
GIS means Geographic Information System.

No, it's a straight (*ahem*) question.

It seems to me that the excuses for not covering Lambda are the
same as for not covering philatelists and train-spotters. Or
the reasons.

And, frankly, I'd prefer to see QST cover neither philately, train-spotting,
nor buggery.

Now that I've said that admittedly inflammatory thing, let me say that
ALL of these folks are legitimately hams, who inter-weave other key aspects
of their lives with ham radio. Be it stamps, trains, or what they point
their genitals at.

However, it seems to me that the 'angles' are irrelevant, and QST has
recently had the annoying tendency to show the cub-reporter's need for
an 'angle' story in order to fill up space.

The technical content of our journal has, in recent months, really
stunk. Oddly, some of the best technical material has been in the
'Beginner and Newcomer' section; perhaps in counting types of articles
for editorial purposes, these have counted as, and hence displaced,
more technical topics for more advanced hams.

I wouldn't mind the occasional article on "Hams Who Use Their HT's While
Bungee Jumping," if I didn't find that, by the time I wade through all
the ARRL and FCC news, and the semi-irrelevant "Human Interest" fluff,
I don't often seem to learn anything solid from QST. I'm better off
finding a back-issue and re-reading something by Lew McCoy or Doug
DeMaw.

Assuming that you're on a private plane and transmitting with the consent of
the pilot....

You might try an HF/SSB HT and look for someone to set up a collect patch.
Although I've never used one of these little beasties and have no idea how
well they work, AEA used to offer a 10M model, and that I believe J-Com still
carries them under its own label and offers models for several different bands
including 10M, 20M (hah!), and 40M.

------------------------------------------------------------------------

Here's a consideration in airborne operation:  please be mindful of
your "advantage".  Under nominal conditions your "footprint" is going
to extend over a 200 mile radius when transmitting from FL200.  That
covers a _lot_ of repeaters.  Before I transmit within the repeater
input segment of the band, I do extensive homework in the repeater
directory on the ground and monitoring in the air before trying to
hit a "specific" repeater.  I would discourage spur-of-the-moment
repeater work from high altitude.

Don't get me wrong.  I _love_ airborne operation on 2 meters and 70cm.
There's nothing like getting a report of full quieting from 275 miles
away when your putting out 2.5 watts from an HT.  I'd encourage anyone
who gets the chance to try it (legally).  But it involves more than just
walking on board and keying up.

BTW, for the home-grown lawyers out there, my operations were fully
compliant with Combined Federal Regulations, Part 97, paragraph 97.101
and Federal Aviation Regulations, Part 91, paragraph 91.21.

This subject has gone around so many times it's almost laughable.  Anyway,
the bottom line is this:
1.  Most airlines specifically prohibit radios (and other electronics)
 during flight; there is an FAR on this.
2.  On non-airline flights, it is the pilot's responsibility to determine
 if he/she wishes to allow the transmissions, with ONE exception:
3.  Radio transmission during IMC operations is specifically prohibited
 by FAR.

I am a pilot, I am a ham....unfortunately, I find the two don't mix very
well (when I'm piloting, I'm too busy hamming).  However, I have no objection
to another ham transmitting while I fly.  I have never had any trouble with
any ham radios in my airplanes.  Note that the airline FAR is a precaution...
and when you're talking about the lives of hundreds of persons, I can
certainly understand why this precaution is taken so seriously.

Cheers!

I recall once making a patch for someone flying over (presumably not on a
commercial airliner)

If you do want to try this, remember that amateur repeaters rarely (if ever)
permit long distance calls, so you could only phone someone in a city you were
flying over, while within range of the local repeater.  It would not be
possible to contact either your origin or desination while in mid-flight.
